"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.
It's like her very existence, from the 
moment she was born, contradicted itself.
وكأنّ وجودها بحدِّ ذاته منذ اللّحظة
التي وُلِدَتْ فيها يناقض نفسه
Es scheint, als wäre ihre gesamte Existenz
ein Widerspruch, seit sie erschaffen wurde.
Se contradice desde que tomó
forma física en este mundo.
Se contradice desde que tomó
forma física en este mundo.
Et ça remonterait au moment même
où elle a commencé à exister.
E ha iniziato a farlo subito dopo
aver ottenuto un corpo fisico.
É como se a própria existência dela, desde
 quando ela nasceu, fosse contraditória.
