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...
I wasn't satisfied with 
the happiness I had with Pochita.
لم أكن راضياً بالسّعادة الّتي قضيتُها مع بوتشيتا
Pochita an meiner Seite
hat mir nicht gereicht zum Glück.
No estaba satisfecho con la felicidad
que me daba tener a Pochita.
No me bastaba con vivir
felizmente con Pochita.
Mes jours peinards avec Pochita
ne me satisfaisaient pas.
Essere felice con Pochita non mi bastava
Eu não estava satisfeito com a
felicidade de ter o Pochita comigo.
Оказалось, что мне мало
счастливых деньков с Потитой…
มีโปจิตะก็มีความสุขมากแล้ว
แต่ก็ยังไม่รู้จักพอ
