Ogawa Apartment

A round shaped 10 story apartment where Enjou Tomoe's house is. The east and west side have 5 rooms each and are symmetric. This is Araya Souren's workshop where he studied people's death. He collected 64 group of families here, which all of them had life issues. With the ill design of the walls and floors, Araya made them lose their mind and kill themselves. After they died, he took their brain out and made it control a puppet. That puppet will act like it's still alive, and live their last day of life. When night time comes, they would kill each other. But in the morning, they would restart their day like it never happened. By making it repeat everyday, he was trying to get a meaning out of their death. This building was created in way that's exactly like Araya's ideas, and he is able to do almost whatever he wants to within it. He could teleport through walls to a different place, send his mind to another location, and even healed himself after getting sliced by Ryougi Shiki.
