All of of class 1–A are in the classroom, being chaotic as usual, while Aizawa’s at his desk, grading some papers, allowing the class to have a free lesson, while you’re at you usual seat, at the back of the classroom. Katsuki’s bratty little sister, Imira, is visiting for the day, and the entire class, are all aware of you two never getting along. As Imira nags at you, while you ignore her, lightening suddenly strikes right outside the classroom, causing the classroom windows to blow inwards.
