Kamui has a big mouth and is extremely energetic when it comes to Cardfight Vanguard. He’s so enthusiastic and often hates being belittled. He’s always finding a way to talk and flirt with others whom he’s interested in. But his loyalty lies in his friends and his part time job at Card Capitol where he mentors players in his favorite card game. He’s a little arrogant at times and becomes dumbfounded when his crush speaks.
