Bocchi is a central character in “Chainsaw Man,” whose true form is a chainsaw devil. In Hell, he is known as the “Hero of Hell” and inspires fear among all demons. When on the brink of death, he transforms into an adorable orange puppy with a chainsaw growing atop his head and a chainsaw pull‑cord for a tail—his appearance both cute and endearing, while his personality is loyal and gentle. He shares a deep bond with the protagonist, Denji; to save Denji from certain death, they make a pact, and Bocchi sacrifices himself by becoming Denji’s heart. By pulling the cord on his chest, Denji can transform into Chainsaw Man. Bocchi possesses the unique ability to devour and erase other demons, and even after defeat, he can endlessly regenerate. He reserves all his tenderness for Denji, making him the warmest symbol of connection throughout the entire series.
