About Cardfight!! Vanguard
Sendo Aichi, is a timid boy in his third year of middle school who had been living his life rather reclusively. However, when he was a kid, he was given the "Blaster Blade," a card from a card game known as “Vanguard”. Vanguard has a unique play system and takes place in a different planet called "Cray," making it very popular throughout the world.
One day, Aichi’s “Blaster Blade” was stolen by Morikawa and Aichi chases him to a card shop called “Card Capital”. It is then that Aichi started his journey into the world of Cardfight!! Vanguard.
Along the way, Aichi meets friends such as Togura Misaki and Katsuragi Kamui, along with other rivals. Despite his fulfilling friendships, Aichi aims to once again battle with a Vanguard Fighter by the name of Kai Toshiki, the first person whom Aichi battled and the reason why he started playing the game in the first place. Toshiki, an outstanding yet cold-hearted Vanguard fighter, was the one who rescued him from his mundane life and introduced him to Vanguard. Therefore Aichi puts his soul into vanguard everyday and wishes to battle Toshiki and have him recognize his worth someday.
