"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.
Big Bro Takuru, how could you just 
leave without saying anything?
أخي تاكورو، كيف لك أن تغادر دون أن تقول كلمة؟
Takuru, du bist fies.
Takuru, eres malo.
Te fuiste sin decir nada.
Takuru, eres malo.
Te fuiste sin decir nada.
– Méchant, tu pars sans rien dire…
– Je ne veux pas écouter !
Sei cattivo, Takuru!
Takuru-nii, como você foi sair
 assim sem nem falar nada?
