Chainsaw Man: Dai-2 Bu

Sometime after leaving Public Safety, Denji has now started to go to high school, while he also continues to exterminate devils. He still wishes to get a girlfriend and often tries to "accidentally" expose his identity as Chainsaw Man. Meanwhile, the War Devil returns to the world seeking revenge against the Chainsaw Devil. It possesses a loner high school girl, Asa Mitaka, who goes to the same school as Denji and makes her search for the Chainsaw Man's true identity. (Source: Chainsaw Man Wikia)
