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...”
Can't be unhinged without 
loosening the screws a bit every day.
لا يمكن أن تكوني مُختلّة دون فعل ذلك رويداً رويداً
Du musst täglich
deine Schräubchen lockern.
La locura que se experimenta a diario
afloja los tornillos.
Afloja un poco esos tornillos tuyos.
Les vices,
ça aide à le déglinguer rapidos.
L'accumulo delle esperienze
che fai ogni giorno ti allenta le rotelle.
Pra se libertar, tem que afrouxar
os parafusos um pouco por dia.
Я день за днём расшатываю
крепления своей «крыши».
