Ikkou, Chitose, Hinata, Sakura, and Kazuki go on a haniwa excavation together. Kazuki shamelessly seduces Ikkou but is constantly thwarted by her fanboys. In a rage, Kazuki accidentally releases an evil spirit, that of a giant haniwa. Hinata is forced to make Master Devil, her little fire-spitting-demon pet, into a monster to destroy the spirit.
