Cardfight!! Vanguard: Link Joker-hen

Months after the Asia Circuit, Aichi Sendou enters Miyaji Academy hoping to enjoy a normal high school life without giving up the card game that has shaped him. When his classmates dismiss Vanguard as childish, he decides to build a Cardfight Club from nothing, gathering new and familiar players while confronting a student council determined to keep the club from being recognized.

What begins as a struggle for a place to play soon grows far more dangerous. A sinister force known as Link Joker begins corrupting cardfighters and turning friends against one another, forcing Aichi and his allies to defend not only their bonds, but the future of the world connected to Vanguard itself.
