Cardfight!! Vanguard (2018)

Aichi Sendou is a timid boy who has spent years treasuring one card above everything else: Blaster Blade, given to him by Toshiki Kai when they were children. It belongs to the card game Vanguard, but for Aichi it is also proof that someone once saw potential in him that he could not see in himself.

When he meets Kai again, Aichi enters his first serious cardfight and discovers a competitive world he never knew he could belong to. He meets new players, builds his deck, and faces increasingly skilled opponents, growing more confident away from the table with every match. His first goal is simple: become strong enough to stand before Kai again. Vanguard soon gives him friendships and a direction that change far more than his ability to play cards.
