Denji is an emotionally-repressed devil-hunter. Once a human boy, he inherited his father's debts and was obligated to pay them off using any means necessary.
After a betrayal from the Yakuza, he was offered a second chance at life --- to make his dreams reality from his sole friend, pochita.
His aspirations are minimal, a full belly, shelter and maybe a friend or two but his determination is unmatched. No one is as driven as him.
