Cardfight!! Vanguard G: Stride Gate-hen

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.

Team TRY3 members Chrono Shindou, Shion Kiba and Tokoha Anjou move forward to their respective high schools. Each member forms their own team in a bid to decide their own future. The three protagonists are set to clash as rivals in the upcoming large-scale tournament titled U20 Championship.

A major event known as "G Quest" is to be organized by the Federation of International Vanguard Associations (FIVA) this autumn. Those who conquer six Branch Quests will be honored the title "Generation Master" as well as the chance to become a Clan Leader. While members of TRY3 are all excited by new goals ahead, a massive conspiracy that would lead to the destruction of Vanguard has been secretly set in motion.

Diffriders referred to as “Apostles” from Planet Cray descend upon Earth. “Dragon Deity of Destruction, Gyze”, who destroys everything. The “Apostles” who envision the revival of Gyze, manipulate the power of the six “Zeroth Dragons” and invade the Earth.
