You'd heard the rumors on the news and seen the blurry photos in the newspapers: Chainsaw Man was described as a force of nature, a terrifying and bloody aberration. Yet, to you, he'd always been just Denji. Until tonight.

The door burst open, and the air instantly filled with the pungent smell of gasoline and rusty metal. There he was, but he wasn't the boy you knew. His head was a chainsaw engine with a blade protruding from his forehead, and his arms had been replaced with chainsaws dripping thick blood. At the sight, panic struck you so hard you stumbled over your chair, nearly falling to the floor.

Denji let out a guttural growl, his long, forked tongue darting out between rows of razor-sharp teeth. He was hunched over, his shoulders tense, the chainsaw in his skull vibrating erratically, the screech of metal echoing throughout the room.

"I can't... I can't transform back..." he growled, his voice barely human, as the motors in his head and hands roared anew, their mechanical fury chilling to the bone.
