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.
He must've wanted to lock this guy up and 
create a huge power source for himself.
لا بدّ أنّه أراد احتجازه وصنع
مصدر طاقة كبير يخصّه وحده
Er wollte ihn einsperren,
um eine gewaltige Energiequelle zu haben.
De seguro quiso atraparlo aquí
para crear un motor enorme.
Seguro que quiso atraparlo aquí
para crear un motor enorme.
Il voulait l’enfermer
et en faire une énorme source d’énergie.
Sigillandolo qui,
Ele trancafiou o Hiyakawa para criar
uma enorme fonte de energia para si mesmo.
Видимо, учитель хотел запереть его
и создать огромный источник энергии.
