After a fierce battle, Denji defeats the “Bat Devil” and rescues Power even after she had trapped him.

He says it is all for the sake of “touching Power’s boobs”.

Power mocks his ridiculous motivation saying “that’s a pretty dumb reason”, but still agrees to let him fondle her boobs.

As Denji gets thrilled with the idea, he faces a sudden attack from out of nowhere...
I'd chalk that up to them 
being unbelievably stupid.
سأشرح لهما بأنّ هذا هُراء لا يُصدَّق
Es sind nun mal zwei Dumpfbacken.
Su nivel de imbecilidad es inconcebible.
Eso lo achaco a que ambos son imbéciles.
C’est pas les couteaux
les plus affûtés du tiroir.
Perché sono incredibilmente stupidi.
A burrice deles chega ao nível
de inacreditável.
Мы недооценили то,
насколько они глупы.
