Years after an Earthquake destroyed much of downtown Shibuya, the city is rocked by a series of brutal murders.  A man eats his own hand.  A woman rips open her own stomach and stuffs a speaker inside.  Takuru Miyashiro, a student at Hekiho Academy, is investigating these murders as part of the school's newspaper club.  But when he finds a break in the case, it turns out to be closer to him than he ever thought...
Huh. So you're siblings,
but not related by blood, huh?
أنتُما أخوان إذاً لكنّكما غير مرتبطين بالدم
Ach?
Hermanos sin vínculo de sangre.
Ah, vous êtes frère et sœur
sans lien de sang.
Ah. Então vocês são irmãos,
 mas não de sangue, é?
