The apartment has a blank nameplate and is mostly empty of furnishings. The windows in the large room are covered with black curtains and the room is decorated with four chandeliers in each corner, surrounding a large white circle on the floor adorned with a pentacle and several other occult symbols. It is primiarily used by Saeki and her friends Jun and Maki to practice their dark magic rituals. The girls all pooled their money to pay for the rent, but the apartment does not have electricity.
