The special product of this town is pumpkin.... Pumpkin and Halloween are used to liven up the town. Shunsuke's high school usually has a school festival at the end of October and his class plans to open a ghost house for the festival. There is an old house standing next to his apartment and it seems no one lives there. They decide to use this house as a ghost house. Shunsuke goes inside to look around and meets monsters.... He runs away but next day, a girl comes to his place with three followers. It seems that he met them before... actually, they are the ones he met at the old house! "We request for your cooperation!"
