Shortly after her hospital visit, Kotoko meets Kurou, the young man she helped two years prior. She takes the opportunity to confess, she who has the appearance of a schoolgirl, who has one leg, a glass eye, and who communicates with spirits…

Kotoko receives a request for help from a giant snake, who is the guardian spirit of Tsukuna Swamp. It appears that a murderer named Tanio Aoi disposed of a body in the snake’s swamp, but there’s something that’s just not sitting right with the snake. After learning about Kuro’s powers, Kotoko asks Kuro to accompany her on this journey, but Kuro declines for a certain reason…

Yokai, ayakashi, spectres, demons, mononoke, and ghosts... Everything has order, and you must never go against the order. Kotoko's fourth solution is accepted by the users on the wiki site and Kuro is able to give the final blow to Steel Lady Nanase. Will that be enough to finish her off?! And what exactly was Rikka's motive?

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!

Two friends meet for dinner in a classy unagi restaurant, and get distracted by an apparently young girl who is confidently dining there alone. Somehow, this leads to talk of murder...
