"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.
And then you will appear,
after having given your suicide declaration.
وحينئذ ستظهر أنت بعد إعلانك عن انتحارك
Zu gegebener Zeit wirst du dort aufschlagen
und deinen Selbstmord verkünden.
Ahí aparecerías tú, que en teoría
afirmaste que te suicidarías.
Ahí aparecerías tú, que en teoría
afirmaste que te suicidarías.
Et c’est là que tu apparais,
toi qui as annoncé ton suicide.
Sarà allora che comparirai tu,
che hai annunciato il tuo suicidio.
E então você aparece, logo depois
 de dar sua declaração de suicídio.
