Denji, a teenager drowning in his dead father's debt to the yakuza, hunts devils alongside his chainsaw devil Pochita until a betrayal fuses the two and turns him into Chainsaw Man. These two feature-length compilation films re-edit the first TV season, following Denji into Public Safety under Makima's command, where he is teamed with Aki Hayakawa and the blood fiend Power. Each part also adds Chainsaw Days, newly animated segments adapting the short extra chapters of Tatsuki Fujimoto's manga.
