He is shy and stammers often. According to him, he is easily pushed around by his sisters who end up teasing him or forcing him to dress as a girl in public (to which many men find him attractive).It isn't until he starts playing Vanguard that he gets some backbone and being more open about how he feels. Despite this, he is still weak willed to a degree.In Cardfight!! Vanguard will+Dress, he became the leader of Team Blackout following Danji and Tohya's departure.
