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...
Only problem with dogs 
is I can't stand the stench.
مُشكلتي الوحيدة مع الكِلاب هي
أنّني لا أتحمّل رائحتهم النّتنة
Aber ich hasse Hunde. Sie stinken.
Pero yo odio a los perros
por malolientes.
La putada es que no aguanto
el hedor de los perros.
Mais j’aime pas les chiens.
Ça pue, ces bêtes-là.
Però, i cani puzzano e io li odio.
Mas eu não gosto de cachorros,
porque eles fedem.
