The main character of this story, Aichi Sendou, is a rather shy junior highschool student who doesn't even stand out in class. However, this rather withdrawn boy who normally spent his time looking over his shoulders has a strong support in his life. It is the card, Blaster Blade, which he received as a kid. That card was the main driving force behind him starting cardfights and changed his life forever. The name of the card game: Vanguard, which takes place on an alternate world called "Planet Cray", took the world by storm with its fresh and exciting game system. Filled with an overwhelming interest for Vanguard, Aichi has met many new rivals, as well as many new friends like Misaki, Kamui and many others. During these encounters, Aichi has grown to appreciate the world around him. For Aichi, there is one more goal which he has set his heart on. That is, to challenge another cardfighter, Toshiki Kai, to another cardfight again. Toshiki Kai, a super strong high school student in Vanguard, who has a rather proud and cold demeanour. He is also the one who introduced the game to Aichi in the first place. To Aichi, Kai not only saved him, but is a leader (vanguard) who has led him to discover the card game, Vanguard. Aichi will continue to work hard and hone his skills at Vanguard. All the time dreaming of the day when he will have a chance to challenge the one whom he looks up to, Kai---!
