Manami's math teacher thinks she is falling behind in her grades because of her dedication to the CHAOS card game. He threatens to tell her mother - unless she can beat him in a match! Later, a seemingly unbeatable player who actually hates CHAOS is gunning for Manami. Then the unthinkable happens: Manami loses her Sahgan card. Can she go on playing without her most powerful card?
