"Let's meet at the place where it all began." The true plot is revealed as Takuru travels to the Hikariwo. There he eets the other person behind the series of brutal killings.  But a deeper mystery lurks in the background: what Serika is telling him doesn't make sense, and he's convinced that as horrible as the story is, there's more to it than even he knows.
I can't keep you alive.
لا أستطيع إبقائك على قيد الحياة
Ich kann dich nicht
am Leben lassen.
Ya no puedo mantenerte con vida.
Ya no puedo mantenerte con vida.
Je suis maintenant incapable
de sauver ta vie.
Non posso
Eu não posso te manter vivo.
