Serika is taken by the strange man she meets, Takuru, into the school basement. Takuru says that he has an important task to do there, but he's reluctant to take her along at all...
And that's the reason I

Eso es lo que me permitió regresar.
C’est ce qui a permis
mon rétablissement.
E essa foi a razão pela qual pude me recuperar.
