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.
That was the one thing 
that hadn't betrayed me.
.كان ذلك الشيء الوحيد الذي لم يخنّي
Der einen Person,
die mich nicht verraten hatte.
Je n’ai jamais pu m’en détacher.
È stata l'unica che mi sia rimasta leale.
Foi a única coisa que não me traiu.
Только он и оставался мне верен.
