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”...
Everyone is serious about this except you.
الجميع جادّون حيال هذا فيما عداك
Außer dir meinen’s hier alle ernst.
Todos estamos en esto en serio,
menos tú.
Eres el único
que no se toma esto en serio.
Personne prend ça à la rigolade.
Tutti quanti fanno sul serio, tranne te.
Tirando você, todo mundo
tá levando a sério.
Все, кроме тебя,
пашут тут всерьёз.
