"Taishi Miwa" is a minor character, and later one of the protagonists in Cardfight!! Vanguard anime and manga. His Vanguard circle is yellow.


He is a friend of Toshiki Kai; they have been friends since they were young and he is Kai's only friend. (However, this plot seems to have been amended in Neon Messiah, with the appearance of another childhood friend, Ibuki Kouji.) He understands Kai and plays Cardfight with him. Unlike Kai, he's much nicer and friendly to people, and loves to joke. He also goes to the same school as Kai.


Like Kai, despite continuous reference to 'Miwa' both in-series and out even by friends, Miwa's given name is in fact Taishi.


Season 2

Miwa was left behind in Japan to look after Card Capital with Izaki as the Acting Shop Owner during the Tournament Period.

Season 3

Miwa is now a senior with Kai. During his fight against Shingo, Shingo underestimated Miwa's skill and Miwa manages to wipe him out easily.

He later faces off against Misaki during the regional qualifiers, using his deck full of Seal Dragons, but falls short of defeating her.

When Kai returned to Japan after travelling around the world following his Reverse, Miwa confronts him, having learnt of cardfighters suddenly becoming strong and gathering more into their group worldwide from the net. He was also able to deduce that Kai was the cause of the growing chain of the Reverse fighters, despite hoping that he was wrong. Saddened upon knowing of the expected truth from Kai, he challenged Kai, using his old Kagero deck with Dragonic Overlord the End, only to lose to Kai's new ace card, Star-vader, Chaos Breaker Dragon. He subsequently gets Reversed as well.

After getting Reversed, he plays the role of being Kai's right hand, going off to defeat the underground fighters and even Jun so that they would not interfere with Kai's desire to fight Aichi.

He is seen with Kai at Tatsunagi Industries welcoming Aichi, Misaki, Naoki, Kamui, and Shingo. He challenges Aichi to a cardfight, saying he wants to test him, but ends up fighting Misaki. He manages to get the upper hand with Dauntless Dominate Dragon "Яeverse" but ends up losing to Misaki's new ace card, Omniscience Regalia, Minerva. After being defeated, he reverts to normal but feels sorry for Kai for being alone again.

Season 4

When Aichi disappeared, Miwa also lost his memories of him. At school, Miwa was seen with Kai in their own vanguard club, where Kai challenges him to a match. During the fight, Miwa struggles to remember the person that Kai keeps on mentioning, but to no avail. As the match reaches to its climax, Kai rides Seeker, Thing Saver Dragon and continues to attack, but Miwa successfully guards all three barrages. Realizing that he must use his own power to recall the person that he forgot, he break rides Dragonic Overlord and attacks with full power. However, Kai manages to guard all those assaults, leaving Miwa close to giving up remembering the blurry images looming around his head. Then during Kai's turn, he activates Legion, calling Blaster Blade Seeker to the vanguard circle alongside with Thing Saver Dragon, triggering Miwa's memories of Aichi and thus beating him. In some part of a match, Aichi asked Miwa what is his plan and Miwa answered he is going to an elite university with Misaki. Misaki helped Miwa to pass the entrance test.

After the match, Miwa learns of a butler that has some sort of a connection to Aichi.

G Season 2

Miwa makes a reappearance in Cardfight!! Vanguard G: GIRS Crisis, during the "G Quest". He is seen as an employee at Card Capital, being called the Sub-Sub-Manager by Misaki, and as a guardian in the G Quest in the Dragon Empire.


Season 1

Miwa uses a Kagero deck similar to Kai's. Yet, he only had 2 on-screen battles against Aichi Sendou in Episode 38 and against Katsumi Morikawa in episode 51 and lost.


In Season 2, Miwa uses a Narukami deck since the Kagero clan is sealed.

Season 3

In Season 3, Miwa returns to using the Kagero clan adding Dragonic Lawkeeper to his arsenal. Later, he changes his deck to revolve around the Seal Dragons.


When facing off against Reversed Kai, he uses Kai's old Kagero deck utilizing the Break Ride, Dauntless Drive Dragon in conjunction with Dragonic Overlord the End, using their re-stand skills in order to put extreme pressure on his opponents.


Upon becoming Reversed, he swaps out Dragonic Overlord the End for Dauntless Dominate Dragon "Яeverse". The Crossbreak Ride retires Grade 1 or lower units for every Grade 1 or higher unit drive checked as well as add 3000 power to its attack. Along with Dauntless Drive Dragon's Break Ride skill to re-stand, it can retire up to 4 Grade 1 or lower units as well as gain a maximum of 12000 additional power by the end of the turn. 


G Season 2

He once again uses a Seal Dragons deck, focusing on adding power based on the number of Grade 2s the opponents have.






  • When the seal is broken, the dragon’s flames will reduce everything to ashes! I ride… Hellfire Seal Dragon, Blockade Inferno!
  • At the end of an endless quest, this is the pinnacle of its evolution. Sublimate your savage soul and show your true form now! Break ride! Dragonic Overlord the End!
  • Squirming black dragon slashing in the darkness, bestow despair upon him with your fang of destruction! I ride Dauntless Dominate Dragon "Яeverse"!
  • (JP): Let there be light! Give power to that hidden fiery soul! I ride Perdition Dragon, Pain Laser Dragon!
  • (JP): Seek mate! Line up, two souls! Take revenge on the enemy with power that is fired up with passion and hope! Legion!
