An incident occurs again at a school where supernatural powers gather!

Aono trees were involved in an incident in which their roommates had disappeared when they woke up in the morning. She resolved the case, made her new roommate, and finally began to get closer to her, but when she woke up in the morning, her "new" roommate did not come down from the bunk bed. She was surprised to see that she hadn't disappeared fortunately, but she didn't seem to be breathing at all ... That's why it's another incident at the Third EMP Academy.
