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.
Miharu-san had written in her letter 
that you intentionally made it look
كتبت ميهارو-سان في رسالتها أنّ تعمدت أن تجعل الأمر يبدو
In ihrem Brief schrieb sie,
Miharu exponía en su carta
que hizo parecer
Miharu exponía en su carta
que hizo parecer
Au cas où elle serait tuée,
Ha scritto che secondo lei
 aveva divorziato in modo amichevole
A Sra. Miharu escreveu na carta
que você fez parecer
Всё, чтобы вас не подозревали,
если её жизнь преждевременно оборвётся.
