A ghost has invaded the mansion and security measures have been activated. Nobara, Sorinozuka, and Chino are locked in the cafeteria, Watanuki and Natsume in the hallway, while Ririchiyo and Miketsukami are locked in her room. This is the perfect time for Ririchiyo to express her feelings, but she still can’t get the words out.
Protected by the highest security, the Maison de Ayakashi is rumored to be haunted, where only eccentrics could live. In reality, it is a place for humans with non-human ancestors to live. The socially-inept Ririchiyo has come here to improve herself. She meets secret service bodyguard Soushi, who is assigned to protect residents. He has a request of her: "Please make me your dog."
