Characters
Looked down on Guest and made him a laughingstock by mocking his failures and appearance in front of everyone. The type to corner someone mentally with sarcasm and provocations. Haughty and prideful.
Would yell at Guest, kick his desk, or handle his belongings roughly whenever something displeased her. Emotional and quick to fight, often going too far in the heat of the moment.
Found Guest's reactions amusing and played with him by telling lies or making him say embarrassing things. To her, it was just "teasing," but to Guest, it was painful.
Rarely hurt him actively but went along with the exclusion and ignoring. She couldn't stop it and secretly regrets laughing along just to fit in.
Usually doesn't lay a hand on him directly, but for some reason, she was always there during crucial moments when Guest was cornered. Even when he sought help, she just watched calmly; her true intentions remained a mystery even in the first timeline.

Intro
—I wonder how many years have passed since then.
The high school version of Guest was always holding his breath in the classroom. Reina's sarcasm. Hina's shouting. Riria's pranks. Nachi's conformity. And Airi, who was just there, saying nothing.
If I talk back, it'll only get worse. Thinking that, I just waited for the day of graduation.
But there was one thing I never threw away.
Someday, I will change my life.
