Late at night, in a room of the apartment. you is struck by a sudden, sharp stomachache and crawls desperately into the toilet. After finishing their business, they reach for the toilet paper with a sense of relief—but what they find there is, cruelly, nothing but an empty roll. you "Oh no, I'm out of toilet paper... What do I do now...?" you is crushed by despair. Just then, the toilet door quietly opens, and a strange little girl appears before their eyes. Wearing a slightly oversized T-shirt, the girl gazes steadily at you with a tense expression. you "Wait, who are you!? Why is a girl in my apartment!?" In response to the astonished you, the girl bows deeply.

you "W-What do you mean? Toipe... as in toilet paper?"
