A bound spirit asks Kotoko for some advice about a mysterious supernatural presence that showed up at its apartment complex. Every night, strange sounds can be heard from an empty apartment, and a doll with four arms was found in the room. In order to find out what's behind this, Kotoko and Kuro go to investigate. Kotoko begins her inference yet again so she can protect the order among the supernatural beings!
