King of Cards: Volume 1 (King of Cards)

Manami Minami doesn't know a lot about "Chaos," a trading card game that is very popular among the kids at her school. Her cousin Tamotsu -- one of the leading players in Japan -- accompanies her to a card store so she can purchase a beginner's set. But when that set contains "Sahgan The Sorcerer," rarest of all Chaos cards, Manami's world turns upside down. Not only does every fanatical Chaos player around challenge her, but she also starts having visions of Sahgan himself, who offers her advice on how to win!
