Ai admires delinquents and applies to Mana and Hikari to become their apprentice. At first she is rejected, but a word from Junichi, the team's leader, allows her to become their apprentice. At that time, Junichi receives news that Manabe has returned from the juvenile detention center. Manabe is a delinquent from a different town and holds a grudge against Junichi and his friends.

Mana and Hikari are both leaders of girl gangs in the same town. They are rivals and constantly fighting. Recently, they heard rumors that their town is being vandalized. Eventually, Mana, Hikari, and their friends are also harmed. They each think it is the opposing gang that causes the harm, but it turns out it's a gang from the neighboring town, with dangerous backing. Can Mana and Hikari protect their town?
