A haunted school building is shown at the episode's beginning. Lala, Risa, Mio, and a frightened Haruna are seen conversing about ghosts and monsters. Lala then suggests that the four of them and Rito should go explore the haunted house. As they all enter the building, a lock closes behind them. They continue to explore the old school and hear what sounds like approaching footsteps. Rito notices Haruna's fright and tries to leap at the approaching figure, only to find out it's Yami. They then hear a piano which chases after them. Yami slices the piano into pieces and everything seems alright...
