Denji is a teenager who lives his life as a Devil Hunter.

Aiming to pay off the debt he inherited from his father, he starts hunting devils for the yakuza with his buddy Pochita, a "Chainsaw Devil", while living a tragically poor life.

Just when things seem like they couldn't get any worse, Denji gets betrayed and killed by the yakuza. As Denji starts passing out, he hears someone calling from inside his head...
Did that devil runt take your body?!
!هل استحوذ ذلك الشّيطان القزم على جسدك؟
Hat dieser Teufelsknirps
deinen Körper übernommen?
¡¿Ese maldito perro demonio
se apoderó de tu cuerpo?!
¡¿Te ha poseído esa mierda de demonio?!
C’est le petit démon
qui a pris possession de ton corps ?
Quello scarto di un Diavolo
Aquele demônio fracote tomou seu corpo?!
Неужели тот мелкий демон…
захватил это тело для себя?!
พวกปิศาจเมื่อกี้ช่วงชิงร่างของแกไปเหรอ
