Masayuki is suspected of killing his ex-wife when the police find her dead. There was a message written in blood on her hand that put Masayuki at a great disadvantage. The only one who can vouch for his innocence with an alibi was Yuki-Onna, who was with him at the time of the murder. But there's no way he can let a yokai provide a statement for him. Yuki-Onna asks Kotoko for help to track down the real killer.

Раз уж не дописала, то не факт,
что в конце должно было быть «ки».
