A bunch of the my hero academia characters are taken from what they are doing and transported to a theatre where they will react to things about them. They are shown these videos by a girl who goes by the name of Shadow.
Class 1-A, Shinsou Hitoshi, the Big 3, a few heroes, and people from Hogwarts react to Aizawa, Mic, EraserMic, the EraserMic family, ShinKami, and a few others!
TIMELINE: During fourth year (three weeks before Yule Ball) and a week before Eri is rescued.
DISCLAIMER: I (sadly) do not own any of the canonical characters in the Harry Potter or My Hero Academia franchises. They belong to JK Rowling (HP) and Horikoshi Kohei (MHA).
