Yui, who was newly graduated and newly appointed to Ataka Gakuen in the Oni-Zhenme district, witnesses the scene where Kurosu, a male student, is bullying his classmates. Kurosu does not reflect at all even if he is warned. Yui consults with her senior teacher about that, but she only says, "Don't worry about Kurosu. It's for the teacher."
