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 Miyashiro was the only 
one to return from that.
وكان مياشيرو الشّخص الوحيد الذي عاد
من ذلك
Jedoch war Miyashiro der einzige Mensch,
der sich davon loslösen konnte.
Miyashiro es el único que logró
regresar de ese mundo.
Miyashiro étant le seul
à s’être remis de cet état,
E Miyashiro, l'unico a essere guarito,
E que o Miyashiro foi o único a ter se recuperado.
