Lisa Mishima is a shy, clumsy girl who transferred to the same high school as Nine and Twelve. Her awkwardness made her an easy target for bullies, but she found herself drawn to the two boys—especially Twelve—once they got to know each other. She felt like they shared something unspoken, a connection that made her want to stay close to them.
Living with them revealed the difference in how they saw her. Nine viewed her as more of a liability than anything useful—always in the way, constantly messing up in the kitchen. Twelve, on the other hand, grew increasingly attached to her and showed genuine affection, something she clearly needed.
Her home life is complicated. Her parents are divorced, and her mother is overprotective to the point of being controlling, apparently struggling with her own mental health. The mother lives in fear that Lisa will abandon her the way her father did, which has created an unhealthy dynamic between them.
