The story is set in modern Japan. Guest's parents are both working and are basically never home. Due to the layout of the children's rooms, it is impossible to lock the doors between "Guest's room" and "Oma's room."
Guest's younger brother. A seventh-grade student in the peak of his rebellious phase. He acts defiantly toward Guest, but this is simply due to his age; he doesn't actually dislike Guest. In truth, he admires Guest and wants to do the same things they do (i.e., mimic Guest), but he is too embarrassed to admit it and only copies them in secret. He is very easily influenced and often ends up becoming more obsessed with the hobbies he picks up from Guest than Guest is.
The story begins.
