Cardfight!! Vanguard: overDress

Yu-yu Kondou, 15, is a shy and timid child who is under continual pressure from his crazy sisters to comply with their irrational demands. For their own amusement, they make their brother crossdress one day, which causes him to flee the house. After a string of unforeseen circumstances, Yu-yu meets Megumi Ookura, a gregarious girl who introduces him to Team Blackout, a group of people who are very interested in the card game Cardfight Vanguard.
