Gai Usui is a minor character in the Cardfight!! Vanguard Anime, and the brother of Yuri Usui.



He is known as Team Caesar's "Gladiator." Gai styles himself as Koutei's bodyguard, and so takes the field ahead of his teammates. His favored Vanguard is Super Dimensional Robo, Daiyusha, and like Koutei he works to reinforce his Vanguard with supporting units before striking out. However, Yuri often chides Gai for not having a clear winning image which has caused him to lose several key cardfights.


During the VF Circuit he was defeated by Ali Pajeel and Toshiki Kai.


Gai uses a Dimension Police deck centered around Super Dimensional Robo, Daiyusha. However, as Yuri tends to remind him, Gai doesn't exactly have a clear winning image going into certain fights and ends up losing them as a result.
