Ep. 12: Hideki investigates a haunted apartment room after hearing a horror story from Minoru's Persocom Yuzuki.

Hideki becomes terrified of a specific apartment room after hearing a ghost story while asking Minoru’s custom-made Persocom Yuzuki about the internet. Believing his building is haunted, he suffers from self-induced hallucinations driven by paranoia. The tale involves room 104, where the number four, or shi, is considered unlucky in Japan because it sounds like the word for death. The story claims a woman was murdered there while waiting for her lover. Hideki, Chi, Shinbo, Minoru, and Yuzuki team up to investigate the location. Their investigation reveals that the frightening events are merely a misunderstanding, dispelling Hideki’s fears and the supernatural reputation of the room.
