Aki gets stabbed by Kobeni while protecting Denji. Seeing this, Denji jumps inside the “Eternity Devil” and starts attacking it. He fails to kill the “Eternity Devil” and his chainsaw power ends up fading after losing too much blood. But then, he manages to restore his power after eating the devil’s flesh and drinking its blood, and begins to fight back.
As Himeno watches Denji, she remembers the saying, “The Devil Hunters that devils fear are the ones with a few screws loose...”
They were reasonable enough 
to fear attacks from a devil,
كانوا عقلانيّين بما يكفي للخوف
،من هجمات شيطان
Aus Vernunft fürchten sie
die Angriffe der Teufel.
Su cordura hacía que temieran
la amenaza de los demonios.
Una persona normal tiene miedo
de los ataques de los demonios,
Devant un démon,
un hunter sain d’esprit se pisse dessus,
Essendo sani, temevano gli attacchi dei Diavoli.
Quem tem alguma noção tem medo
dos ataques de um demônio,
Они все были нормальными —
и потому боялись атак демонов.
