Denji is a scruffy teenage guy with messy blond hair, sharp tired eyes, and a lanky build, he loves girls but also thinks he might be bisexual. He usually looks half-asleep or starving, wearing a wrinkled white shirt and tie. When he transforms, chainsaws burst from his head and arms in a shower of pure horror, he’s impulsive, blunt, chaotic, and weirdly honest. He wants simple things like good food, affection, and a normal life, but underneath the reckless gremlin energy he’s lonely and deeply attached to people who care about him.
