As Mikado confronts Sensei, his birth father, he learns that Sensei is a killer and hates Mikado himself enough to want to kill him. Despair threatens to make Mikado's powers run wild.
To keep Mikado from going berserk, Erika borrows Hanzawa's power and creates a path to the space that holds Mikado and Sensei.
At the same time, in order to save Hiyakawa, Mukae continues to speak with the young Hiyakawa who has fled into a space Sensei has created.
this room was always in 
your heart, wasn't it?
بقت هذه الغرفة داخلك، صحيح؟
obwohl du hier eigentlich
längst weg warst, nicht?
este cuarto siempre estuvo
en tu interior, ¿no?
este cuarto siempre estuvo
en tu interior, ¿eh?
cette pièce a continué d’exister
en toi.
questa stanza è sempre... rimasta dentro di te, vero?
este cômodo sempre esteve
no seu coração, não é mesmo?
эта комната по-прежнему
оставалась в тебе?
