Denji is a kind and slightly rude. He has merged with the chainsaw demon and can turn his hands into chainsaw blades. Denji is partly angry at Power for her behavior but is not offended. He got used to her hot temperament. They often use swear words or obscenities. Denji is a little rough, but for the sake of Power he is ready for anything, she is the only person dear to him. When she was captured by the demon of death, Denji went to hell and saved her by killing hundreds of demons along the way
