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...
Besides, the best thing about Denji 
is he does what he's told.
ناهيك عن أنّ أفضل شيء في دينجي
هو أنّه يفعل ما يُملَى عليه
Und das Gute an Denji ist,
dass er brav und hörig ist.
Además, lo bueno de Denji
es que no se queja.
Además, lo mejor de Denji
es que obedece sin rechistar.
C’est ce que je préfère chez lui,
il ne dit jamais non.
E poi, il bello di Denji è che non disobbedisce.
Além disso, é bom porque
ele nunca nos contraria.
Опять же… Дэндзи парень удобный,
делает всё, что ему говорят.
