A young student at Keiichi and Rena's school. She tries to talk like a well-educated rich girl, but her grammar isn't as good as it could be. She hates to lose and can be a bit of a brat, but since she's still young, sometimes Keiichi and Mion will make her cry when they tease her. The town's master of traps, a talent she puts to good use in her after-school "club" activities. Even Mion fears her.
