This smiling boy from our fanart Chainsaw-Man Denji Sticker has a bad fortune. As a young boy, he inherited his father's debts from the Yakuza. After meeting Pochita, he becomes a Devil Hunter for the Yakuza to clear his debt. Once the Yakuza, under the control of a Devil, betrays him, he dies, and Pochita becomes his heart. He now becomes the Chainsaw Man by pulling a cord on his chest. After Makima, he became a Public Safety Devil Hunter. Following Makima's death by his own hands, he resigned from his position as a Devil Hunter but kept fighting as Chainsaw Man.
