Christopher wears a green sweater with a frog head design on the hood in Season 2 and a dark blue sweater with cat ears on the hood in Season 3 and 4. He has long red wood color hair. He first appears in Cardfight!! Vanguard: Asia Circuit, episode 70 .
Chris is a 12 year old student at the Singapore Institute of Technology, alongside his friends Lee Shenlon and Ali Pajeel. In his group, he is the most respectful and often has to hold Lee and Pajeel back as they have short tempers. He is also a member of Team S.I.T. Genius alongside Lee and Ali. While only being 12 years old, he is able to attend S.I.T. due to grade skipping. During his match against Aichi Sendou, Takuto Tatsunagi gave him PSY Qualia to fight against Aichi's PSY Qualia. Upon receiving it, Chris was almost instantly corrupted by it and began acting just like Ren and Aichi did. Aichi, knowing of the temptation that PSY Qualia brought, pleaded to him that PSY Qualia was not the way but Chris just waved him off and told him that Aichi was too weak to use that power properly. After that, he confronted Ali Pajeel because of his loss to Kamui Katsuragi, much to Lee Shenlon's anger. Later he defeated Kenji Mitsusada and told him that he has a ways to climb before he can reach his level, and welcomes him in S.I.T.
Later at the final stage of the VF Circuit he and his team watch as Team Q4 win the final tournament. After the winning ceremony, all the teams gather in a room that has a portal that creates a space connected between Cray and Earth to fight a mysterious empty power, Void. Team S.I.T. Genius gets separated with the other teams by Leon Soryu not long after their arrival in the space. Chris uses his PSY Qualia to sense Leon's in order to find him. However, while doing so he seems to be corrupted by Void and then turns on his team and defeats them in a fight. Team Q4 arrived when they heard the commotion and Aichi decides to defeat Chris to free him from both PSY Qualia and Void's hold. As they first begin to fight Chris uses his PSY Qualia to predict that he will defeat Aichi. While Aichi at first does not use PSY Qualia he decides he needs to in order to defeat Chris. Despite Chris's image of victory given by PSY Qualia, Aichi is able to defend himself and defeat Chris with Blazing Lion, Platina Ezel's Ultimate Break, freeing Chris from the influence of PSY Qualia and Void. However, as Chris was the leader of Team S.I.T. Genius and lost, they are sent back to earth.
Chris and his team are first seen at the end of the VF Circuit, where he loses to Aichi. He is later seen at Card Shop Capital where he sees Aichi fight his classmate Naoki Ishida. In episode 135 he comes back from S.I.T. as well as Kenji Mitsusada. however, when they meet up with him they find that he is acting strange (unaware that he had been Reversed by Kai or what Reverse even is). He then challenges Chris to a cardfight where he reveals Dark Dimensional Robo, "Яeverse" Daiyusha who Chris figures out has something to do with Void. However, despite using his new break ride card, he is defeated by Kenji and is Reversed. After Leon defeated and unreversed Kenji, the duo defeated Chris and his teammates, along with Yuri, and unreversed Chris.
Chris appears in the ending song Get Up. He is later seen in the Card Capital in episode 196.
G Season 2
Christopher makes a return as a guest fighter for the Zoo Branch G Quest. Currently, he's 15 and the current president of Genius Communication Technology. According to Shion, Christopher Lo is a recognized top-class Asia fighter as well a child prodigy. He is seen later fighting against Tokoha in a cardfight as part of the finale for Zoo Branch's G quest. He lost the battle against Tokoha after her drive check revealed a critical trigger which brought him to 6 damage, ending the battle.
In the fight against Tokoha, he utilizes a combination of Cath Palug and Crayon Tiger to power up his other rear-guard so he can overpower his opponent. This lets him attack multiple times with more power than before while also replenishing his hand with Coiling Duckbill, Crayon Tiger and Cath Palug's skill after they stack on top of each other on a rear-guard thus giving Christopher both offense on his turn and defense on his opponent's.
