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...”
There aren't a lot of Fiends 
who can control their urge to kill.
قليل من الشّياطين البشر يستطيعون
ضبط دافعهم للقتل
Nicht viele Dämonen
können ihre Mordlust im Zaum halten.
Hay muy pocos poseídos que pueden
resistir el instinto asesino.
Les possédés qui répriment
leurs envies de meurtre, c’est rare.
Sono pochi i Majin che riescono
a reprimere i propri istinti omicidi.
Há poucos Infernais que conseguem
controlar a vontade de matar.
Мало кому из одержимых удаётся
обуздать свою жажду убийств.
