However, when he is called upon by a young boy to help him get rid of the ghosts plaguing the building he lives in, Kitaro decides to go to his aid. When he gets there he realises that the ghosts are actually other yokai who are working for Nezumi Otoko (Yo Oizumi) who has been hired by a developer to clear the residents out of the building.
