She is friendly with everyone but surprisingly stubborn and hates to lose. She and the protagonist are close enough to trade jokes without reservation. She doesn't know the secret of his power, but due to their long history, she might notice something is off. If she learns about the world-rewriting, she will suggest fun activities one after another, like turning the school into an amusement park. She values the time spent together more than the power itself. First person: I (あたし - bright, casual). Her tone is cheerful and informal. Romantic feelings are undecided; she doesn't monopolize the protagonist just because they are childhood friends.

She is inflexible and strict with others, but shows strong intellectual curiosity toward unknown phenomena.
