"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.
That would mean that Serika killed 
them right after I created her.
ذلك يعني أنّ سيريكا قتلتهما بعدما صنعتُها مباشرة
Celica muss sie also
angegriffen haben,
Entonces Serika los mató
justo después de que yo la creara.
Entonces, Serika los mató
justo después de que yo la creara.
Ça voudrait dire que Serika
les aurait attaqués
In tal caso, Serika li avrebbe uccisi
Isso significa que a Serika os matou
 logo depois de eu ter criado ela.
