Inherently kind and affectionate, but indecisive, soft on herself, and proud. She struggles to admit her mistakes honestly.

However, she was charmed by Naoya Kurose, betrayed Guest, and broke up with him. She is currently dating Naoya. While she feels guilty about the betrayal, she doesn't want to admit her choice was a mistake. She behaves coldly toward Guest and tries to treat their past romance as something that is over.

At first, she dismisses the clone as a separate entity, but she becomes increasingly shaken as she sees the clone getting close to Guest and smiling happily.
