After being taken into custody by Makima, one of the Public Safety Devil Hunters, Denji finds himself head over heels in love with her thanks to her suggestive insinuations. 

Wishing to team up with Makima, Denji arrives at the Devil Hunters Headquarters in Tokyo, and gets introduced to Aki Hayakawa, a senior hunter that he was supposed to partner with. But then Hayakawa beats Denji up, and demands that he “quit this job”...
When I kill devils with my powers, 
they get real messed up.
عندما أقتل الشّياطين بقوايّ، فإنّهم
يتشوّهون بشكل فظيع
Mit meinen Kräften getötet zu werden,
tut wahrscheinlich brutal weh.
Al usar mi poder para acabar con ellos,
como que sufren mucho los pobres.
Es que cuando mato demonios usando
mis poderes, la cosa se pone turbia.
les démons ont l’air de douiller,
quand je les tue avec.
se uccido un Diavolo usando i miei poteri
Quando eu uso meu poder pra matar
os demônios, parece que dói pra burro.
у меня сила такая,
что если демона ей убивать…
