Mikado, Mukae, Sakaki, and Erika head to Sensei's house. It's necessary for Hiyakawa's sake too. But Sensei has used the sinister power he's gathered to block the roads, so they can't move forward. As they try to force a way through, a portion of the power swoops down, enveloping Sakaki. But all it does is pass through him...?! It seems that the effects of what Erika did to save his life have made Sakaki "deathless."
That's because you keep 
clinging and won't let go.
ذلك لأنّك تواصل التشبّث، ولا تفلت
Doch nur, weil du an mir festhältst
und mich nicht gehen lässt …
Es porque tú te aferras
y no quieres soltarlo.
Es porque tú te aferras
y no quieres soltarlo.
Perché tu ti aggrappi a me
e non vuoi lasciarmi andare!
Porque você fica se agarrando e não me deixa ir!
