Cardfight!! Vanguard (2011)

'Cardfight!! Vanguard' is a card game created by Bushiroad as part of a mixed-media franchise that received an anime adaptation which aired for multiple seasons from 2011 to 2014.

The story follows Aichi Sendou, a timid middle school student who often gets bullied. The one thing that keeps him going is "Blaster Blade", a card from the popular trading card game "Cardfight!! Vanguard". After having it stolen by his classmate one day, Aichi chases him to a local card shop named "Card Capital", where he reunites with Toshiki Kai, an aloof high school student who originally gave Aichi his Blast Blade many years ago. After being challenged to his first cardfight by Toshiki and winning, Aichi reclaims his prized possession and sets out to be a stronger fighter so that he can once again battle Toshiki and have him recognize his worth.
