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.
The flow of time inside 
this barrier is slower...
مجرى الزمن داخل هذا الحاجز بطيء
In der Barriere fließt die Zeit langsamer.
Le temps s’écoule lentement,
de ce côté de la barrière…
Dentro la barriera,
lo scorrere del tempo è molto rallentato.
O fluxo de tempo dentro
da barreira é mais lento.
