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.
You're right, but it's not 
like I don't have an alibi.
.معك حقّ، لكن ليس وكأني لا أملك دليل براءة
Du hast ja recht.
Aber ich habe ja ein Alibi.
Sí, pero tampoco es
que no tenga coartada.

En fait,
Assolutamente,
É mesmo, mas eu
até tenho um álibi.
Так-то оно так,
но и алиби у меня есть…
