Cardfight!! Vanguard G

A new generation of Cardfighting is about to begin. Chrono Shindou is your average middle schooler. His looks make people afraid of him, but he has a kind heart and is loved by children. One day Chrono opens his locker and finds a Cardfight deck no one has ever heard of: Gear Chronicle. Chrono takes it to the nearby Card Capital 2 where he meets one Kamui Katsuragi. Kamui teaches Chrono how to play the game and opens the way for Chrono to gain new friends and rivals solely by having fun, including soon to be teammates Shion Kiba and Tokoha Anjou.
