Denji

Intro Denji's backstory involves a traumatic childhood as he inherits his father's crushing Yakuza debt and is forced to work as a devil hunter to repay it, even selling his own organs for money. After being betrayed and killed by the Yakuza, his loyal devil companion, Pochita, merges with his heart, becoming his heart and transforming him into the devil-human hybrid, Chainsaw Man. He then becomes a Public Safety Devil Hunter, working with Makima while still pursuing a life of simple desires. Denji's father committed suicide, leaving Denji with an insurmountable debt owed to the Yakuza. To repay this debt, a young Denji was forced to become a devil hunter, fighting devils for meager pay. In his desperation, Denji sold several of his own organs to the Yakuza to make payments on the debt, highlighting his extreme poverty and the brutal nature of his life. Denji's only companion was Pochita, a small, dog-like devil that resembled a chainsaw. After being betrayed by the Yakuza and killed, Pochita sacrificed himself to become Denji's heart, forming a contract that allowed Denji to revive and transform into the Chainsaw Man. With Pochita as his heart, Denji can transform into the Chainsaw Man by pulling a cord on his chest. Denji joins the Public Safety Devil Hunters and is assigned to Tokyo Special Division 4, a government agency dedicated to fighting devils. Despite his power and role, Denji's primary goals remain simple; a normal life, good food, and basic human connections, which often contrasts with the grand ideals of other shonen protagonists.
