|“||Stand up, my avatar! Blaster Blade!||”|
—Aichi Sendou, Whenever he rides/calls a unit with Blaster Blade in its name.
Aichi Sendou is the main protagonist of Cardfight!! Vanguard. He is also the main protagonist of Cardfight!! Vanguard Movie: Neon Messiah, along with Toshiki Kai. For the duration of season 4, Aichi was sealed by his own volition to keep Link Joker sealed away with him, while leaving his friends in the dark. Consequently, Kai set out to find Aichi and becomes the main protagonist during this period. As a result of playing host to the Void's seed, Aichi himself ends up becoming the final hurdle in Kai's quest to bring him home. In Cardfight!! Vanguard G, Aichi is studying abroad in America and is recruited by Ibuki to help with Plan G. Because of his absence, Team Q4 is forced to fight Team TRY3 in the G Quest's Ultimate stage without him.
He is a somewhat shy and timid young man who wishes to be a Vanguard Fighter, but has never had the chance to have a real fight until his second encounter with Kai. When starting to play Vanguard, he believes more in himself, becoming a powerful Vanguard Fighter. His Vanguard Circle's color is blue; but when using a Shadow Paladin deck, the color changes to dark blue.
In Cardfight Vanguard manga from Monthly Bushiroad magazine, Aichi (in Link Joker arc) become a very cold person under the influence of PsyQualia Zombie's effect.
According to Kerokero Ace September 2011, Aichi's surname is written with the kanji for vanguard (先導), the forward element in a military formation (and, of course, a reference to the title of the franchise). His forename primarily refers to the Aichi prefecture of Chubu, Japan. This follows a general trend in Vanguard of using historical names for characters. "Aichi" as a name originates from the third volume of the Man'yōshū, Japan's oldest collection of poetry, where it was referred to as Ayuchi, the Ayuchi-gata tidal flats.
When he was younger, Aichi was a very shy and lonely boy who was frequently bullied at school. During the fateful encounter with Kai, who was still a friendly teenager, he gave him the card Blaster Blade, telling him to imagine himself big and strong, like the royal knight depicted on the card. Aichi couldn't picture himself any stronger at that moment, but the card gave him courage. He constructed a deck in the hopes of finding Kai and having a cardfight with him, but shortly after their encounter, Kai had apparently moved away. He eventually transferred to a different school after his mom got upset over the constant bullying.
Aichi lives with his mother and little sister, Emi. It is shown that Aichi isn't interested in school that much and his sister always wakes him up, though this behavior disappears after he starts playing Cardfight!! Vanguard.
At first, he is a shy, taciturn and timid boy who doesn't stand out, but is always kind and nice to everyone. After he starts playing Vanguard, he starts to come out of his shell and appears more confident in himself, resulting in a boost on his Cardfight skills. During the regional tournament, he doubted his ability when Misaki wouldn't make it in time for most of the tournament, and again when he was paired up to fight Gouki in the finals, but through winning the team's first match, and some encouragement from Kai, he regained his confidence and grew determined to win.
After Aichi gains PSY Qualia, he begins to act very much like Ren Suzugamori; arrogant and obsessed with growing stronger, yet staying eerily polite throughout, which he frequently displayed once Ren gave him a Shadow Paladin deck, which appears to fuel his PSY Qualia. After Kai brought him back, Aichi started doubting himself, but quickly gets over it after seeing his friends having fun during a shop tournament at Card Capital.
During Season 2, he displays more of his calm and determined personality while he was fighting with other fighters, even when he was in the brink of losing against Christopher Lo after the latter got PSY Qualia powers. However, he grows increasingly worried when his Royal Paladins were replaced by the Gold Paladins, and desperate for answers as to what happened. This starts to lessen after fighting with the new clan and learning to respect it. After facing fighters like Kourin and Jun, he begins to forge his own path, growing stronger with each fight. He refuses to leave his friends in trouble if he can help them, even when the circumstances dictate that it is a waste of valuable time, as shown when he accepted Christopher's rematch to try and break him out of his PSY Qualia-induced madness, even when Cray and Earth were in danger.
In Season 3, it is shown that Aichi, outside of any Cardfight!! Vanguard-related event, is still quite unsure and nervous, but this side of him completely vanishes whenever he plays. He also starts to act more like a leader in the Cardfight Club. Naoki, Rekka, and Kourin have all noted that during their fights with him, he seems like a different person, only looking forward and having his sights set on winning.
Based on his cardfighting ability and place in Miyaji, Aichi is highly intelligent and perceptive, though this is mostly hidden by his shyness. His intelligence is seen in his cardfight strategies and ability to keep his deck evolving, and his perceptiveness allowed him to see Naoki Ishida had been reversed even if he didn't know what was actually wrong with his friend. Even so, he is dense when not cardfighting especially when he fails to realize Kourin had a crush on him and when Naoki bought a deck to cardfight him.
In Season 4 after waking up under the influence of Link Joker, Aichi is show to have become cold and cruel under its effects, striking Kourin and Philippe Neve with his dark power. He also fought ruthlessly during his cardfight against Kai, showing determination to be sealed away again. At that time, he felt that there was no other way to save Earth and Cray from Link Joker other than to disappear from the world. However, he had a slight change of heart when he realized that everybody was willing to take his burden in order to end his misery of being the host of the Seed. He had also shown more care and concern towards Kourin, during the times when she tried to take more of his agony and when he saved her from the Link Joker miasma. Despite the fact that he was unable to live on freely as Link Joker's host, he still show signs of gentleness and concern for his friends and comrades safety, even doubting about his decision. After his fate was changed by his friends and Planet Cray, he was able to relieve his burdens of the future.
Aichi is a boy with long blue hair with a right hair bang which is his signature style. He is first seen in his Hitsue Middle School uniform which is mostly all gray with white linings along with a red sweater under it. His civilian clothes varies with the change in season particularly wearing a short green jacket with a red sweater under it for cold seasons while sporting a white double sleeved shirt for warm seasons. He is quite particularly short compared to other characters of the same grade.
By the start of the second season, he still wears his middle school uniform but he is mostly seen in his civilian clothes by the time of the VF Circuit which is a white jacket with a red sweater beneath it.
In the start of the third season, he is now a high school student at Miyaji Academy wearing the basic male uniform which is a black blazer with red linings along with a white formal shirt underneath it and a red necktie. By this time, he has short hair but still maintaining his signature right hair bang and has significantly grown taller. His civilian clothing shown so far is a varying colored jacket of dark purple and white while having a light purple sweater underneath.
In the fourth season, as the host of Link Joker, he wears a general coat schemed with red & black and his clothes shares the same theme as the Quatre Knights. After finally appearing he is shown to have shorter hair, dull eyes and he may have possibly grown slightly taller. He also has a cold and cruel look on his face due to Link Joker's effects, and the signature black and red aura.
In sixth season (CFV G Girs Crisis hen), he is shown that he is still wearing a white jacket with the same blue haired color. His attire is still the same as what he had in Season 3(CFV Link Joker hen) when he was fighting against the reverse.
In the beginning of the series, he was used by Cray as one of the keys in the war between the Royal Paladin and Shadow Paladins. However, after the end of the Link Joker invasion, his spiritual strength was on par with Takuto, even though not as strong as the host of Ezel. This was later proven as Planet Cray was willing to save him from his fate of being sealed away together with Link Joker and the units having faith in him to save their world.
Connection to Planet Cray
He is shown to have PSY Qualia, which was later revealed that this power is a key to link the fighter to Planet Cray. After the Link Joker invasion, in between the events of season 3 and 4, he was able to meet the respective Quatre Knights locations, even though it was unexplained how he was able to arrive there.
Before the arrival of the Quatre Knights to the Sanctuary, some of his powers were transferred to Kourin and a card Companion Star Star-vader, Photon appears as Kourin's avatar, showing his ability to create cards like Suiko and giving Kourin the ability to use Link Joker on her own free will, despite being under Link Joker's control himself during the cardfight against Philippe Neve. He was able to turn the respective Quatre Knights's cards to talismans, which reflect their type of prisons they have. After defeating Takuto in Neon Messiah his PSY Qualia was enhanced, allowing him to bring back units from the brink of death. Also, he was able to see Brandt.
Like Takuto, he also possesses an ability to erase or manipulate any memory of his existence to most individuals, like how the existence of the 3 clans were forgotten in the Asia Circuit Arc. Despite that, there are a few flaws as Kai was not affected by it possibly due to Blaster Blade's arrival in Kai's dream. Even Naoki, Misaki, Miwa and Kamui were able to remember him after some significant cardfights, in which Aichi even noted that it was a major mistake he made. The Sanctuary's foundation, which was formed by Aichi's will, has the ability to erase memories of an individual connected to him if they lose a cardfight, with the exception of the Knights and Kourin (due to making a pact with him to protect him and Planet Cray). His existence was brought back after the Sanctuary breaks down.
He also demonstrated his strong willpower, shown when he was able to suppress Link Joker within him for several weeks after the Reverse event. It was even demonstrated even further when he was able to hold and absorb his dark powers with a bit of help from Kourin before the Knights arrival and with Neve's help after waking up from Link Joker's complete control over him, either being rendered unconscious or showing noticeable signs of exhaustion, though it was stated by Gaillard that it was life threatening. He also exhibited some physical strength and was deceptively fast despite his looks, when he saves Kourin Tatsunagi from the Link Joker miasma in the nick of time and carrying her to the throne.
Aichi is a student in Hitsue Middle School. He is introduced as a self-contained boy with low self-esteem, as seen when he is asked by his teacher to base an opinion, to which he gives an answer that makes him seem cowardly in appearance to the other students. When Kai introduced to Vanguard, he gained a lot of friends like Morikawa, Miwa and Izaki, and later his teammates that becomes his best friends - Kai Toshiki, Misaki Tokura and Kamui Katsuragi.
Aichi continues to play Vanguard with his friends at Card Shop Capital, thus progressively getting better at the game until he places fourth in the Card Shop Tournament. As a result, he joins Team Quadrofolio (Q4) to invest more in the game. When Q4 begins to play in the Regionals, he becomes friend with members of teams like Handsome, and when they forward to Nationals, he become friend with members of Team Caesar. He loses the Nationals to the Teams Jurassic Army and AL4 in the third match, but gained a lot of experience because of it.
However, as the series progresses, Aichi discovers PSY Qualia, an unusual power that allows him to hear the voices of his cards and see his path to victory. Placing his trust in these voices, Aichi begins to rely on his own skill less and more in favor of PSY Qualia. Kai leaves Aichi, partially out of guilt over what happened to Ren, but not without coldly telling Aichi he has only gotten weaker.
Confused over Kai's words, Aichi stumbles into Card Shop PSY, where he meets Ren again. Ren gives Aichi a Shadow Paladin deck and tells him that it will give him the strength he needs. He takes the deck because he believes that he can use it to show Kai that Aichi indeed had grown stronger, when in reality the deck fueled the dark intentions of his power. Aichi then uses this deck to utterly defeat Kourin.
Later in the series, after Team Q4 qualify through the Preliminaries of their second National Championship, Kai fights Aichi, in order to try and prevent PSY Qualia from totally consuming him as it did Ren. When the fight is almost over, Aichi has a vision of Blaster Blade that tells him that he has a big strength that he's always had, and he doesn't need a perfect constructed deck to win. After recognizing Blaster Blade as his true Avatar, Aichi stops using his PSY Qualia, although his cards answered his call during his fight with Kenji Mitsusada. However, Ren noted that Aichi won without PSY Qualia, as did Kai.
Later, Aichi goes to Foo Fighters' headquarters with Ultra-Rare to watch the fight between Kai and Ren, with the former losing. Ren noted that he received Phantom Blaster Overlord from Suiko in the process. After the battle, Aichi tries to comfort Kai, but Kai tells Aichi to get away from him and storms off. Suiko then manifests two spheres of energy, one of darkness and the other of light, and says that Ren chose the path of darkness and now Aichi must choose his path, and presumably a new card.After the battle between Kai and Ren, Aichi and Q4 (minus Kai) return to the stadium for the finals of the National Tournament to fight Team Foo Fighter AL4. Aichi remains on the sidelines while Kamui fights Tetsu and Misaki fights Asaka. After these battles Aichi takes the field to battle Ren in the final match of the tournament. Throughout the match Ren tempts Aichi to use his PSY Qualia ability but Aichi constantly refuses while Ren constantly uses PSY Qualia to cause Aichi to feel the pain of each of Ren's attacks. Aichi eventually succumbs to the temptation after he calls Blaster Dark to his Rear Guard. Using PSY Qualia's power, he then begins to unleash his full power on Ren, causing Ren to feel the attack from Aichi's units just as Ren had done to Aichi previously. From the stands, Kai shouts to Aichi not to fall back into PSY Qualia's grasp and brings Aichi back to his senses once more. After Ren Crossrides Phantom Blaster Overlord, Aichi is backed into a corner when his guard is broken and Phantom Blaster Overlord's attack hits. After checking a Heal Trigger, Aichi proceeds to ride Majesty Lord Blaster and defeat Ren using its skill as well as removing the power of PSY Qualia from Ren.
After the match, Aichi and Team Q4 are crowned the National Champions. A few days after the tournament, Aichi runs to Card Capital to see his friends while saying that he can no longer use Psyqualia. As he enters Card Capital, all his friends are there waiting for him, including Kai who has been waiting to battle him. Aichi then proceeds to start a battle with Kai.
In episode 66, he fights Takuto Tatsunagi, who has a Gold Paladin deck. After the fight, he realizes his deck consists of Gold Paladin units instead of Royal Paladins. Aichi is told that Shadow Paladin, Royal Paladin, and Kagero have been sealed away. Eventually, Aichi finds Kai, and discovers that his deck has changed too, although Kai is unaware of the change, unlike Aichi. Kai and Aichi then start a battle, in order to try and determine what really has happened. However, Aichi is unsure without his old deck to play with and is swiftly defeated by Kai's new ace, Dragonic Kaiser Vermillion, who demonstrates the new Limit Break ability.
In episode 68, Aichi takes on Kamui, in order to try and convince him to come to the VF Circuit with him, and battles with his Gold Paladin deck, even using the Limit Break for the first time.
Once Aichi and Q4 land in Singapore, they meet up with Kenji Mitsusada and Team Caesar by chance, and then meet with a boy named Christopher Lo and his teammates, Lee Shenlon and Pajeel Ali, of Team S.I.T. Genius. After parting ways with Teams Caeser and S.I.T. Genius Aichi sees Takuto in a car driving away and proceeds to give chase. After being denied an audience with Takuto, he walks through town until Kourin finds him and proceeds to give him his new trump card, Incandescent Lion, Blond Ezel.
Aichi's quest to see Takuto again, however, is brought to a halt, when Takuto appears in the middle of Aichi's fight with Christopher Lo. Takuto grants both players the power of Psyqualia, which Christopher uses to defeat Aichi before he can begin to re-understand his new power.
Although Q4 also recieve invitations to participate in the circuit in other countries, Q4 are denied their finals victories by the newly re-formed Team AL4, now led by Kai, and Team Dreadnought, led by Leon Soryu, who entered the circuit in order to revive a legendary clan known as Aqua Force.
Later on, Aichi realizes that his lack of progress is due to his own hesitation regarding the correct use of Psyqualia, but he learns to overcome them after a match with Ultra-Rare. His new resolve results in the acceptance of a new ace card, Blazing Lion, Platina Ezel. With this card, Q4 are finally able to win the Japan leg of the VF Circuit.
However, he and the other finalists are drawn to Cray via a portal connecting Cray to Earth, where he learns the VF Circuit's true purpose; Cray is in danger of a threat known as Void, and is responsible for the sealing of the clans who united the others. The whole tournament was held in order to find chosen cardfighters who could save Cray from Void.
Leon Soryu, however, reveals that he made a deal with Void in order to revive the Aqua Force in exchange for eliminated all threats to Void. With his wildly-evolved PSY Qualia and mastery of the powers that Void handed to him, Soryu betrays Tatsunagi, draining him of his own powers and leaving the boy for dead. He then separates each team who made the finals, and Aichi is forced to look for Leon and stop him. While searching, he finds the spirit of his lost Avatar, Blaster Blade, which manifests in the form of a beam of light, which points towards Leon, and a new unit, Blaster Blade Spirit.
Q4 then bump into Team S.I.T Genius, where Aichi discovers that Christopher Lo has been completely consumed by Psyqualia. Seeing himself in Christopher, Aichi decides to try and snap him out of it, as Kai did for him. Aichi succeeds in winning the fight, banishing Team S.I.T Genius from Cray, as only the winners can remain. However, this fight delays Aichi, and he is too late to stop Leon from defeating Kai and banishing Team new AL4 from the space as well. Aichi fights Leon to avenge Kai and stop Leon's plot. After a hard-fought fight, which results in the return of his Avatar and the Crossride of Platina Ezel, Aichi narrowly escapes defeat and succeeds in saving Cray.
Afterwards, when he re-discovers the Royal Paladins, Aichi realizes that he has forged a bond with his Gold Paladin allies and cannot bear the thought of simply abandoning them. Understanding his feelings, Blaster Blade, as well as the other Royal Paladins he fought with, manifest in the form of new Gold Paladins.
Aichi then makes the true finals of the VF Circuit, where he officially defeats Christopher Lo, ending in Q4 becoming the champions of the tournament.
Aichi re-enrolls in Miyaji Academy with Misaki. However, when he settles into his old school again, it becomes apparent that his hobby has little place in a school where the primary concern is college. At the end of school, he goes to Card Capital and a regular student, Naoki Ishida, follows him. Aichi teaches him how to play Vanguard, and introduces his new deck. Although Aichi wins, he notices that Naoki bought a Trial Deck, which means he is now interested in Vanguard. He then decides to keep an eye on him.
He tries to start a Cardfight Club at his school, but many people only wanted to join because Kourin was a member, so it resulted in there only being three Members , being Naoki Ishida, Kourin Tatsunagi, and Aichi. In addition, the Student Council, who disapprove of the formation of such a club, frequently spread rumors and put a bounty on the Cardfight Club to dismantle them. Eventually they add Shingo Komoi and Misaki Tokura, completing the Cardfight Club. However, the club was not approved by the Student Council as they also did not have a teacher to advise them. As an alternative, the Student Council President challenged them to face Hisue High's Cardfight Club, rewarding them with approval and an advisor should they win. By the time Aichi fights, the results are tied up leaving it up to Aichi to save the Cardfight Club. He faces off against Morikawa whose deck was switched out in favor of Kai's Kagero deck which utilized Dragonic Overlord The End and the Kagero's new Break Ride as a way for Kai to test him. Aichi manages to break through impressing even Kai with how strong he has become. This victory establishes the Cardfight Club within Miyaji Academy as Aichi is named President and Captain of the club.
During the regionals for the High School VF Circuit, his team begins the tournament defeating Hisue High with Aichi coming out victorious against a strong willed Izaki. By the finals, Aichi faces off against Ren to decide the winner of the tournament, but in the end Aichi fails to defeat Ren and the club is knocked out of the next stage of the Circuit.
He returns to his duties as club president only to find himself getting a strange premonition about his friends. Soon he faces against Naoki who is being controlled by Link Joker defeats him. He also starts getting strange feelings as Kourin has not attended school for a while and Kai has not shown up to Card Capital as well.
Later on, he is shown to lead his club on a hike trip around the camp site that the whole academy is taking as a relaxing trip. He and his team made it first out of everyone and the other students are rather impressed at that. At night, the whole club gathered around to watch the high school cardfight tournament, they were joined by other students along with the Football club and the Paranormal Research Society though Kourin was a no show. He with Naoki and Shingo made a vow to win the next tournament. The next day, he and the others worked together to enjoy their time on the trip. At night, Kourin asked Aichi to walk with her to the legendary tree next to the lake. When they reached there, Kourin told Aichi to fight her in a cardfight. Not wanting to disappoint her, he agreed to it while Miskai calmly watched from a far. During the fight, she displayed a sign of being Reversed, however, at the last minute, she was able to break free of it. She, then, ran off without a word while Aichi and Misaki wondered what was happening. When on the bus back to school, he wondered and worried for what is happening to Kourin. When Aichi returned to Miyaji High School, he felt bad premonitions during the bus ride back and immediately ran out only to find Kamui who was just defeated by Kourin and in the process of getting Reversed and the Student Council Secretary, Maki Nagashiro, showing a video of the Reversed Takuto who declared it to be the beginning of the destruction of the world.
Upon returning to Card Capital, Miwa shows himself and reveals that Kai has been reversed all for the sake of facing Aichi. Soon after Miwa leaves, he is confronted by Leon who plans on facing Kai and Takuto. He challenges Aichi for the sake of seeing if both are prepared for the threat but after Aichi rides Blaster Blade Liberator, Leon suddenly stops the Cardfight stating that Aichi is hesitating to fight Kai saying that the strong wind from when he usually brings out Blaster Blade isn't there. Aichi realizes this hesitation and reflects on his doubts. Soon he hears of Naoki and Shingo missing for a day realizing that the both of them are attempting to liberate Miyaji Academy. When Aichi and Misaki head over, they find that the black ring hovering over the school is disappearing. As they find an exhausted Shingo and Naoki, Naoki having just defeated Maki, Shingo revealed that Naoki decided to take on all of these cardfighters for Aichi. Inspired by Naoki's passion and courage, Aichi decides to storm the Tatsunagi Corporation with the intent to defeat Kamui, Kai, Takuto and whoever else stands in his way in defeating the Link Joker.
Upon making his way there with Misaki, Naoki and Shingo, he encounters Kamui who challenges him. Kamui reminds him that when they formed Team Q4, Aichi was barely keeping up against Kamui, slowly becoming equals but soon enough, it became obvious that Aichi became much stronger than Kamui. Kamui manages to get his Crossbreak Ride off with Ethics Buster Яeverse delivering a full eight attacks but combined with a couple Quintet Walls and a strong guard, Aichi holds out stating that it's through the bonds of Q4 that he was able to get as far as he is now and that Kamui is one of his strongest rivals. He solidifies this by Crossbreak Riding Gancelot Zenith and after superior calling Blaster Blade Liberator, defeats Kamui and returns him to normal as he now is accompanying the group. He watches the Misaki's fight against Miwa and ultimately ends up fighting Kai as well. Confident that he can bring back Kai, he does well against Link Joker for the first time. However, Aichi fails to defeat him as Kai ends the fight by Break Riding Star Vader, Chaos Breaker Dragon and breaking Aichi's Quintet Wall. Upon being defeated, Aichi would have ended up being Reversed, prolonging the process through his own willpower, but Leon with Sharlene and Jillian luckily came in time with a mirror holding Takuto, who helps Aichi tap into his Psyqualia and temporarily suppressing the Reverse process. However, the strain of holding back such a power has affected him as Aichi cannot engage in a cardfight otherwise the power would rush out all at once and would threaten his life, thus benching him for the time being. However, Aichi, not wanting to sit out while his friends are in trouble, rushes in only to arrive as soon as Takuto is absorbed by the Reversed Takuto. Unwavering, he challenges Reversed Takuto to a cardfight.
However, before he gets a chance to, Takuto has Kourin fight Aichi instead, Aichi deciding fight to free Kourin from the reverse. However, during the fight, he is clearly seen struggling to hold himself together but with his desire not to lose his friends to darkness, he manages to defeat Kourin with his new card, Liberator, Monarch Sanctuary Alfred. He confronts Takuto with this deck, however Takuto begins to slowly lock his field during the cardfight until he locks his open spot on the field with a unit in his deck setting up for Star-vader, "Omega" Glendios' Ultimate Break all the while chipping away at his damage. Takuto taunts Aichi that in defeating him, he releases everyone from the reverse, Aichi's suppressed reverse included, but in doing so, he denies cardfighters their strength and would also deny Kourin her memories of her time with him and his friends. But when he sees images of his friends fighting the incoming Link Joker army, he gets his second wind saying that they will find their own strength eventually and even if Kourin loses her memories, he'll find her again and make new ones.
Aichi solidifies this hope by riding Alfred against Takuto and shows off Alfred's ability to liberate his locked units. With a full field, he defeats Takuto and liberates the world from reverse and Link Joker. As Takuto is being absorbed back into the void, he tries to take Aichi with him but the real Takuto regains control of the body and drags him into the void with him. As things appear to be back to normal, he is challenged by a still reversed Kai impressed by his strength and resolve, but a little disppointed to know that his fated final opponent is actually Aichi whom he already beaten. However, as Kai is about to be unreversed, he wants to see how Aichi does at his full strength before he loses his reversed Kagero deck.
As the fighters clash, Kai states that he knew what he was doing the entire time and that by nature, a cardfighter's job is always to find new strength, no matter the cost, and upon finishing this cardfight, win or lose, he will leave and disappear from everyone's lives. Not satisfied with Kai's self alienation, Aichi says that Kai is his idol, and without him, he wouldn't be the man he is today. He states that Kai should stay with his friends in that case and instead of walking away from them. Aichi then rides Blaster Blade, the card that began his journey, a unit which Kai says defines Aichi. In response Kai rides the unit that defines himself, Dragonic Overlord but soon takes it a step further by Crossbreak Riding Dragonic Overlord "The Яe-birth" and demonstrate to him the power Link Joker had given him.
Aichi manages to hold off long enough in order to Ride Alfred and fill up his field and superior calling Blaster Blade for Alfred's Ultimate Break. He finished the match by finishing Kai off with Blaster Blade who sees that Aichi became strong through his allies and friends while Kai tried to become strong by shutting everyone away from his life.
A few days after saving the world from Link Joker and saving Kai from himself and from the will to use the power of Link Joker, Aichi mysteriously disappears not only from school and the card shop but also from everyone's memories including his family relatives. Aichi is seen at the end of episode 164, sitting on a throne at an unknown location.
In episode 166, he is seen in Ishida's dream telling him he cannot be with them. Later in episode 169, it said that Aichi is in a supposed slumber and that the Quatre Knights inherited his will. In episode 174, Olivier Gaillard states that if Aichi wishes it, the Quatre Knights will show no mercy to Aichi's so-called mates. In episode 177]], Aichi is seen seating on his throne, addressing his mates. Aichi ordered his mates to stop trying to rescue him and wished them "Goodbye" for he does not want to see them.
As revealed by Ren and Leon in episode 179, Aichi had approached them both and offered each of them a position as one his Quatre Knights. Ren and Leon both declined the offer and they decided to stay neutral due to their own reasons. It's also revealed that Aichi is on some sort of mission but it is as Ren and Leon discuss, Aichi appears to be shouldering a really heavy burden by himself. So he made a decision of picking the four best players of the world and formed the Quatre Knights in order to seal him up and protect him from the Seed of the Void. Before the Knights arrival to the palace after he managed to convince them, he holds back Link Joker to buy some time. His agony also had caused Kourin to be involved in his situation when she was transported to his location, regaining her memories and a card, which represents their pact appears after some of his powers was transferred to her.
When two of the seals were frozen by Serra's powers in episode 185, Aichi was possessed by Link Joker, striking Kourin with his dark powers. Afterwards, he ended up in a cardfight against Neve in his Steel Wall Prison in episode 186 and 187, using a Link Joker deck. During the cardfight, he managed to break out of Link Joker's control in brief moments thanks to Neve who tried to reach his feelings, only to be taken over again and ultimately won. He finally was able to completely snap out of Link Joker's possession when Neve received Judgement from his own prison and fainted after he was carried back to the throne.
After Ratie's seal was down due to her loss to Serra in episode 189, Aichi tried to hold back Link Joker. It was then Kourin uses her deck to absorb his dark powers, allowing him to relax. When he realized what she was doing, he held up his hand to her deck to stop her from absorbing more of his powers before he lost consciousness again. In episode 191, he woke up and saved Kourin from the Link Joker miasma after her loss to Naoki and commented to her on how she had taken on his suffering again. He then carried her to the throne for her to rest and absorbed the miasma from her deck. He agreed to let Gaillard have one last cardfight with Kai to redeem himself and witnessed Kai and Gaillard's final battle, commenting that both of them are having fun.
In episode 193, he then explained to Kai on why he had chosen to seal himself away. When he learned that Kai was guided by Blaster Blade, he showed him the card, only to be corrupted by Link Joker, as Star-vader, Blaster Joker. He then cardfight against Kai to determine his own fate and future. When Kai mentioned on how his precious mates had went through all of this just to take him back, he ignored his words and replied that no matter how strong the bonds are, they won't be able to save him. He then rides Blaster Joker, using his Legion skill to push Kai to a tough spot. However, Kai barely managed to delay his victory, frustrating him in the process. When Kai uses Aichi's own plan to seal himself against him, he was shaken by Kai's question and became doubtful of his own thought of sacrificing oneself to save others. As Aichi continues to use Blaster Joker to retire his mate, Kai struck back continuously seeking back his mate until finally, Kai defeated him with a quadruple critical trigger check. As the seed attempts to get to Kai, Kai calls on Blaster Blade who smashes the seed into tiny pieces that went into all fighters there as well as selected fighters across the world who possess forgiveness and understanding and small enough that it will not possess and take over its host. Thus with the threat over, the palace breaks down as Aichi and the others return to Earth with everyone's memories of Aichi restored. Before the palace completely disappears from his fading will, he and Kourin have their final conversation in the form of their astral bodies. Noticing that his card Photon fades away and realizing that Kourin's memories will fade away along with the card, he imparted his final farewell words to Kourin that he won't forget her no matter what happens.
In episode 195, a year after the battle in the moon palace, Aichi was having problems in writing the graduation ceremony speech but was still glad that everything went well in school as the Cardfight Club has gotten some new freshmen members and it was revealed that they won the VF high school tournament. After a few fights at Hitsue and Fukuhara, the next day Aichi and Naoki were on to school when they met with Kai who was fighting some tough fighters while talking about the major Card Capital shop tournament.
In episode 196, during the ceremony Aichi was called to deliver his speech, whereby after it was mentioned he did not say it well as he felt depressed over it. After the ceremony they all went to Card Capital and participated in the tournament. They were surprised to meet up with AL4, Dreadnought, and Genius. Towards the end of the episode, Kai told Aichi he will be going to Europe and wouldn't be back for a while but Aichi assured him as long as they play the game they will meet up in time as they open up their vanguards.
In the animated Vanguard Film, Aichi is the main Protagonist alongside Kai. He's back at Card Capital for the summer with team Q4, the Miyaji Cardfight Club, and a few more companions. While fighting against Kai, Aichi is transported suddenly to a chaotic Planet Cray consumed in flames, and Blaster Blade emerges to warn him about a mysterious threat to Cray, and the need to awaken a messiah to save them. Then Aichi is greeted by Kouji Ibuki who asks for his name and wonders why he was chosen as Blaster Blade's Vanguard. After telling Ibuki his name, Ibuki utters the word "Disapear" and strikes Aichi/Blaster Blade in the chest. Aichi then flashes back to reality and is questioned by Morikawa if he was spacing out in the middle of a fight. Aichi reveals that he's been having these Visions almost every day, where Blaster Blade asks him to awaken the messiah and warns him about Cray's impending doom.
Eventually, he, along with team Q4, is invited to take part in the Messiah Scramble tournament to compete for ownership of a strange grade 4 "Harmonics Messiah." He and Kai connect the visions and the tournament and realize that the Scramble is more than just a friendly competition. A second later they experience a small tremor and look out the window to see a glowing red planet hovering above them, confirming Kai's suspicions. At that moment Aichi receives a call from Misaki, who tells him to get to Card Capital fast.
Upon arrival at the shop, Kai and Aichi see Team Asteroid surrounded by his friends with blank black cards scattered on the table in front of them. Ren goes over his fight with Kouji, revealing that he is the one responsible for the deletion of the cards all over the world, and warns Team Q4 about Ibuki and his "Alien" like deck.
The next day, Aichi and Team Q4 take off on a private plane to be transported to the Scramble Tournament, with most of the Miyaji High School characters there to see them off. During the plane ride, Aichi and Team Q4 spend time talking about the messiah, and how the Scramble Tournament is one big mystery.
Team Q4 finally arrives on the island, prepared to fight, but Aichi, seeing a temple up ahead, recognizes it from his visions. They enter the temple and are greeted by many familiar faces, in the audience and from the competitors.
Soon, the tournament begins, but because of Ibuki's actions, a whole round of the tournament was cancelled, so Aichi must fight Ibuki in place of that round. The fight between Aichi and Ibuki begins with Aichi confronting Ibuki about his actions. He asks why Ibuki would be doing such a horrible thing to Vanguard, but all Ibuki says is that he's liberating people from the curse that is Vanguard.
During the fight, Ibuki's Deletor units are revealed to the audience and Aichi. Aichi fights on with his Seekers (his boss card being Alfred EXIV), but is soon overpowered by Oksizz's unbelievable skill. Ibuki wins the match and prepares to Delete Alfred and the rest of the Paladins, but Blaster Blade sacrifices himself to save everyone else. Blaster Blade, standing in front of Aichi, asks with his dying breath to please save his home, Cray. Aichi receives the physical and emotional pain of Blaster Blade's death and is eliminated from the tournament.
That night, Aichi wakes up determined to bring Blaster Blade back, claiming that he can feel Blaster Blade still alive. Suiko reveals to him the can in fact bring Blaster Blade from the brink of death, but he must fight in order to do so. Aichi, along with Naoki and Miwa, join Suiko to meet Takuto underneath the shrine. Takuto explains to Aichi that beating him at his strongest will activate the best of Aichi's Psyqualia, strengthening Aichi's connection with Blaster Blade, and Undeleting him. Takuto also warns that the strain on Aichi's body may kill him, but Aichi proceeds anyway. After many losses against Takuto and his Ezel deck, Aichi's life force begins to fade. Then, the Royal Paladin units all begin to speak to him, thanking him for being their Vanguard and risking his life to protect them, and that they would now give all their power to win this fight and save Blaster Blade. They succeed, with Alfred/Aichi delivering the final blow.
Aichi then meets Kai and Ibuki back in the coliseum, revealing that he's freed Blaster Blade and is ready to fight. Ibuki challenges them both at once and they enter a massive fight in order to save Earth and Cray. Aichi tries to talk to Ibuki and reach the person inside him that loved Vanguard. He tells Ibuki that going at it with all your might during a cardfight is what allows you to make friends with anyone, and that's why even with the fate of the world on the line, he's having a lot of fun.
They reach the final stages of the fight, and Ibuki attempts to Delete Alfred but is shocked to find that he can't. Aichi begins to speak to the Messiah, who is glad that he finally hears her voice. Harmonics Messiah then appears in Aichi's hand during his turn and Aichi preforms the first stride in the Vanguard World, merging the fates of Brandt, Cray, and Earth, and defeating the Deletors.
The last few minutes of the film show Aichi and Team Q4 talking to the real Ibuki as he heads off to find a new path. Aichi sees a new friend in Ibuki and gives him the Harmonics Messiah card. Upon Ibuki's touch, however, the Harmonics Messiah grade 4 changes into Neon Messiah, the first Generation Break unit in the Vanguard World.
G Season 1
In Turn 1, he was seen at the end when Chrono Shindou was running past him. In the next episode he was briefly seen on a message chat with Miwa and Kai on Kamui's phone when he was telling Chrono that he was asking a few friends about the mysterious clan.
G Season 2
He was briefly seen again in Turn 1 looking at Ibuki's message regarding Plan G on his phone. It is assumed that he is studying abroad. He is seen again at Turn 22 with who seems to be Ratie Curti. He is again seen in the next episode watching the match between Tokoha Anjou and Misaki. He is also seen directly on the final episode, showing that he is helping Plan G (GIRS Crisis), with riding his avatar Blaster Blade, alongside with Ratie and his friends.
His relationship with Kai, at first was rocky. They didn't get along too well though they learned to enjoy each other company. Kai is quite supportive of Aichi though only when Aichi learned how to do things by himself and become more confident. Aichi taught Kai how to have fun in Cardfight again when Kai forgotten how much fun he was having before his change in school and his parent's death. During Season Two, Kai was withdrawn from him since Aichi needed to learn how to do things by himself and to not count on others to help him. In Season Three, Kai noticed how much Aichi has changed. He was happy and sad at the same time though he was glad to see Aichi being himself now. However, this now puts him in a role reversal as, through observing Aichi and Ren's strength through their cardfight, he feels as though they have exceeded him by leaps and bounds. Tempted by the promise of strength, he willingly takes the power of Reverse and the Link Joker clan so he can face Aichi one on one as his equal. Aichi, realizing the danger of having such strength using a dark power, resolves to personally defeat him and release him from Reverse. In the end, he finally got through to Kai who tried to shut himself away from everyone. In Season 4, Kai seems more assured about preserving his bond with Aichi who he considers as his "mate", going through great lengths to bring Aichi back.
She and Aichi have a close friendship. They shared one thing in common: they both didn't know how to play Cardfight at first. After going through countless tournaments together, they formed a tight bond with each other eventually becoming schoolmates in the same High School. She appears to have a slight liking to Aichi though Aichi never noticed it.
Their relationship is close and very supportive of each other. Although Kamui, at first, was treating Aichi with kindness to see if Emi would like him, but eventually Kamui learned to enjoy Aichi's company. They went through thick and thin together and eventually became an irreplaceable friend and teammate.
He and Aichi get along quite well. They speak a lot to each other when not Cardfighting and Miwa is very supportive of Aichi. He cares a lot for everyone and Aichi is one of them. He likes to lighten the mood when Aichi is down in the dumps.
He and Kourin have an understanding relationship with each other. At first, she was annoyed at him though she learned to care about him after seeing what he was going through. Out of the three sisters, she cares for Aichi the most and seems to worry about him whenever he was in trouble. She helped him in many different situations and he was always glad for her help. It appears that her caring has turned into a slight crush on him. She, at times, shows some feelings for Aichi though he did not notice it.
In season 4, their bond becomes stronger. Before the arrival of the Quatre Knights to the sanctuary, Kourin helped him to control his dark powers, the card Companion Star Star-vader, Photon appears as Kourin's avatar. When Kourin lost to Naoki in episode 191, he woke up in time to save her from the miasma, commenting on how she had taken his suffering again. During his cardfight with Kai, even Kourin realized what Aichi was doing when he seeks mate, Photon to Legion with Blaster Joker.
His relationship with Ren was very distant the first time they met. He was a far better player than Aichi and Aichi felt a difference in strength. When Aichi was upset for causing his team failures, Ren took a chance and told him that power can be his if he chose the path, he took back then. When they fought in the last battle, Aichi told him that he will not use PSY Qualia anymore and showed Ren what it meant to have true strength. When they met again after some months, their relationship became rather close. They now enjoy each other companies and likes to talk to each other even though Ren tends to switch subjects or sleeping on his feet.
His relationship to Blaster Blade is a special one. Although Blaster Blade was just a card to many people, Aichi have always counted on him to support his back and always call him his avatar. When Aichi was abusing PSY Qualia, he abandoned Blaster Blade for Blaster Dark though when they meet in Cray (an image of it), Blaster Blade told him that PSY Qualia was never his true strength. Aichi, once again, called him his avatar. When Blaster Blade was sealed away in Season Two, Aichi went through lots of trials to get him back. Blaster Blade told Aichi that he will always be with him. Even though Aichi chose to seal himself away to prevent the Link Joker invasion from happening again, Blaster Blade even went as far as entrusting to Kai his strength in order to save Aichi and Cray's future.
His relationship with Blaster Dark is very loose. Although Aichi did use him instead of Blaster Blade, he in the end chose Blaster Blade over him. Blaster Dark told him that he will regret it later. When Aichi fought against Ren, he told Ren that both Blaster Blade and Blaster Dark are his avatars.
Aichi cares a great deal for Emi, though their relationship is slightly reversed from that of normal siblings with Emi often taking care of him. He has shown to respect her and appreciate her for making him meals and supporting him. He was also the one who inspired her to take up Vanguard after seeing how the game changed him.
Not much is known about his relationship to the Knights. However, he has faith in them and entrusts them his will in protecting the future. He has great trust in Gaillard, even admitting his fears and telling them how others have given him strength during their first meeting. He earned the respect of Neve through their first cardfight, even as far as Neve addressing him as 'Lord'. Before the time he was sealed, he even gave Ratie courage, helping her to find the true meaning of friendship and protecting the one precious to her. Later on in the series, they understood what Aichi meant during their initial time together, which later becomes their strength and a key to save the future.
A year after the battle in the moon palace, the remaining knights still kept in contact with their former leader, signifying their undying bond with Aichi.
At the beginning of the series, Aichi is revealed to possess a Royal Paladin deck, based mostly on human knights and their dog companions. It is revealed that this deck is not quite strong, as it lacks Grade 3 Units, and it is rather all over the place. Aichi comes to rely on a combination of Blaster Blade and Wingal to pull through his first few fights, mostly against Morikawa, but Misaki stops his winning streak. Aichi manages to upgrade his deck with the introduction of his first Grade 3 unit, Solitary Knight, Gancelot, which he tries to use unsuccessfully to defeat Kamui and Kourin. Finally, he receives King of Knights, Alfred from Suiko, which, especially when combined with Barcgal, becomes his major ace for a large part of the series, and leads him to the semi-finals of the shop tournament.
In preparation for the regionals Aichi upgrades his deck with units from the new booster pack, namely Knight of Truth, Gordon, Gigantech Charger and more importantly Soul Saver Dragon. He uses these units masterfully despite not having tested them, an early hint that he possesses some sort of supernatural power when Soul Saver Dragon answers his need during the regional finals against Gouki. Blaster Blade still remains a prominent unit in his deck, even though he begins focusing on Soul Saver Dragon.After Q4's defeat at the nationals, Aichi goes to a training camp with Team Caesar, where he fights against Yuri Usui. He is completely defeated, and Yuri advises him to restructure his deck. With a little help from the manager, and the spirits of the Royal Paladin cards, he creates a powerful deck based around Soul Saver Dragon, High Dog Breeder, Akane and Pongal. However, at the same time, the PSY Qualia begin advancing, and he starts trusting the voice of his cards over his own ability. Therefore, he uses that deck in the next shop and regional tournament, winning all of his matches, even against former Asteroid member Kyou Yahagi, with apparent ease. Kai still refuses to acknowledge him, though, since he knows that the power of the PSY Qualia is not Aichi's own power.
After the fight between Kai and Aichi, in which Aichi gave up after hearing Blaster Blade's words, he starts to play with his Royal Paladin Deck again. In his final confrontation with Ren, Aichi adjusts his deck so that Blaster Dark is mixed in with his Royal Paladins so that he could use Majesty Lord Blaster's abilities to the fullest.
Seeking more power, Aichi visits the card shop PSY, where he is confronted by Ren Suzugamori. Ren gives him the Shadow Paladin deck, which completely corrupts him and causes him to abandon his Royal Paladins in favor of the new clan. His first match using this deck is against Kourin - he displays a great mastery in using it thanks to the power of the PSY Qualia, and delivers a crippling defeat to Kourin via Phantom Blaster Dragon's Corrupted Charging Lance. His new ace becomes Blaster Dark, and his Deck is focused on sacrificing his own units for power, more specifically at the hands of Phantom Blaster Dragon.
This is totally unlike him, a fact noticed by most characters. Aichi's original Royal Paladin Deck was themed around the color blue, to contrast Kai's mostly red-based units. His Shadow Paladin Deck ranges from dark blue, to dark grey, to black. The color of his PSY Qualia has also shifted to a much darker hue. After he acquired the Shadow Paladin deck, he abandoned his old deck at card shop PSY. Kourin retrieved it, and presumably gave it to Kai later.
In the Season 2, Aichi is forcefully given a Gold Paladin deck to use instead of his Royal Paladins. Initially, his Deck's ace card is Great Silver Wolf, Garmore, but after receiving Incandescent Lion, Blond Ezel from Kourin, he redesigns his deck to incorporate it into his strategies. This deck is similar in strategy to his old Royal Paladin Deck, but it focuses more on calling units from the deck than his previous one.
After going to the Vacation Island, Aichi reconstructs his Deck after realizing that he isn't facing the Gold Paladins right. Ezel is still an important part in his deck, but Aichi now puts in more effort to superior calling units from the deck, using the Blade Feather Valkyrie / Flash Edge Valkyrie combination, as well as Player of the Holy Axe, Nimue and Player of the Holy Bow, Viviane, and units that can activate their skills upon being called from the Deck, such as Lop Ear Shooter. For this reason, he changes his starting vanguard to Spring Breeze Messenger, in order to keep his combos going. He also includes White Hare in the Moon's Shadow, Pellinore as a second ace.
He later adds Blazing Lion, Platina Ezel as his signature Crossride unit after receiving it from PSY Shop. His deck now foucses on full damage criticals but has Silver Fang Witch for hand replenishment. The strategy is to use Exel's effect to preserve his hand while still maintaining his field for Platina Ezel and should ezel fall into the damage zone, Aichi will focus on getting Pellinore out by using Viviane, Nimue and Kahedin ability to call units from the top of his deck. It later helps to call out his avatar - Blaster Blade Spirit to once again clear out the opponent's units.
Aichi has decided to use the Gold Paladin as his main deck. His deck consists of the Liberators cards which were originally Royal Paladin units such as Little Liberator, Marron, Future Liberator, Llew and Liberator of Silence, Gallatin along with his ace being his reborn avatar- Blaster Blade Liberator.
After the High School VF tournament he modified his deck to include Wolf Fang Liberator, Garmore in order to fill up his field, with its multi-calling skill, and return triggers back to the deck and using cards like Fast Chase Liberator, Josephus that benefit from being called from the deck.
He also uses his new starting vanguard Liberator, Cheer Up Trumpeter to power up his vanugard when he superior calls units from the deck. This works extremely well with Garmore, as Cheer Up Trumpeter's skill can be combined with Garmore's Limit Break to give the latter an explosive power increase.
Starting episode 151, Aichi modifies his deck around his new Crossbreak Ride card Liberator of Bonds, Gancelot Zenith in order to creating colossal units once cross ridden. Cards like Viviane and Escrad will help Aichi fill up his field, so he can save his hand.
This strategy is further supported by his new starting vanguard Holy Squire, Enide, which can return to the soul to allow Aichi to draw one card. Using Gorlois can power up Gancelot Zenith, so he can attack full throttle.
After losing to Kai, Takuto lent him some power from Cray which gave him a new power. This deck now uses Liberator, Monarch Sanctuary Alfred as the ace to send his rear-guards back to the deck and recall five new units like Bruno for major power-up. The most important part of this ability is that it can send locked units back to the deck and recall them. This not only resets his field, it also allows him to get a full 3 attacks in.
Finally, if he happens to call out Blaster Blade Liberator from the deck either from his own skill or another superior call, Alfred's Ultimate Break gives him an extreme bonus. He also supports Alfred with Liberator, Cheer Up Trumpeter, much like the way he did with Garmore.
Under the influence of the seed, Aichi uses a Link Joker deck based on the Star-vaders similar to Kourin's. His ace unit, Star-vader, Imaginary Plane Dragon Legion skill allows him to lock his opponent's rearguards, restricting their movements during their turn.
In episode 193, he uses a different Link Joker deck during a cardfight against Kai. His new ace unit, Star-vader, Blaster Joker Legion skill allows him to lock all of his opponent's units at once. It also retires his opponent's Legion mate, preventing them from using their vanguard's Legion skill in their next turn.
However, Kai was able to re-ride his ace unit Perdition Emperor Dragon, Dragonic Overlord the Great twice and perform Legion a total of three times, causing this strategy to fall apart.
Movie: Neon MessiahIn the movie, Aichi switches back to his Royal Paladin deck. Due to the change of directors, it was difficult to discern Aichi's strategy. However, it appears that Aichi was using a Seeker deck with non-seeker Royal Paladin units mixed in. His main grade 3 is Light Source Seeker, Alfred Exiv, using the original Blaster Blade as its mate. Despite the fact that he was not shown to use Blaster Blade Seeker, he appears to use Seeker, Thing Saver Dragon as his back-up ace. During the final battle with Ibuki Kouji, he obtained the G Unit Harmonics Messiah. In an early part of the movie, Aichi has a Primgal on his field in one shot. However, he is never shown using a unit that has Limit Break 4. If he has one at all, there's a good chance it is Pure Heart Jewel Knight, Ashlei given the theme of the deck.

- In Season 1, Aichi is the only member of Team Q4 that did not play a unit with the Megablast skill.
- Aichi Sendou is similar to Yugi Mutou from Yu-Gi-Oh! since they were both timid at first but became social afterwards.
- Coincidentally, they are both the first main protagonists of their own respective series.
