Season: 1

Yumi's dad loans Hideki his DVD player, and tells him of a DVD sale coming up. Hoping to get some mature videos, Hideki embarrassingly meets Minoru and sis instead, who offer him a fantasy multiplayer Internet game (Brave Quest Online) that persocoms can play too. Hideki thinks this would be fun to play with Chii. But Hideki knows nothing about hooking up to the internet! Fortunately Shimbo helps him out. Now everyone's logged on, except for Chii; she's missing (in the game)! Oh no, what's Hideki going to do now? Blindly run through the game looking for her of course!

Hideki is scared of a room in the apartment because of a horror story he heard at Minoru's house when he was asking about the internet through Minoru's custom-made Persocom Yuzuki. He becomes paranoid thinking about the story and, believing that his apartment building is haunted, has several self-induced hallucinations. The apartment number in the story is 104, as 4, or shi. "Shi" is the Japanese word for Four (四) and Death (死), and because of this, the number four is unlucky in Japan. According to the story, a woman who was hoping to rendezvous with her lover was killed in that room. Hideki and Chii along with Shinbo, Minoru and Yuzuki decide to investigate. At the end, Hideki and Chii discover that it is all a misunderstanding.
