However, his bad attitude comes from the fact that he has a sleeping disorder, and frequently spends nights on end without a single minute of sleep. During the preparations for the school festival, he is begrudgingly sent to the school's astronomy observatory to gather cardboard boxes, a place which is said to be haunted by the dire happenings of the now defunct Astronomy Club. He finds the isolated place a haven ripe for him to sleep, but while rummaging around, he stumbles upon his classmate Magari
