Denji (デンジ, Denji) is a devil hunter working with a devil Pochita, in attempt to clear his debt.
Denji is a young man blond, scruffy hair. He has sharp yellowish-brown eyes with bags underneath and sharp teeth to match. He is a bit scrawny with protruding ribs due to malnutrition. Once Denji forms a contract with Pochita and Pochita becomes his heart, a chainsaw starter forms in the middle of his chest.
