One night, Tina falls asleep drunk in the Sakuraba Mansion living room, and she hears a mysterious sound from the attic that wakes her up. What's causing this strange sound? The next night, she hears the same sound. Tina assumes there is a ghost and goes into a panic! Not only that, but Chika and Aoi also say that they heard the same mysterious sound. Taeko, who loves ghost stories, hears about the incident and stands up to fight. "I won't let you guys down! So let's exterminate them together!" Ignoring Tina, who is screaming for mercy, they go on to the ghost hunt.
