[Western Crossover] Would a Witcher Have Vigilante Brothers in Gotham?

Jesse Winchester is a demon hunter. He has an adopted brother, an adopted younger brother, and an adoptive father. One day, he suddenly discovers he has a biological twin brother. In Gotham. Gotham! Even demons wouldn't dare go there! * "Bro, I respect your taste, but do you really think wearing a red date-shaped helmet on your head is a good idea...?" * Some dark, terrifying vigilante: What are you doing here? Jesse: (reflexively) (throws salt) (sprinkles holy water) * "I'll bet you're the first person to throw salt in the face of Gotham's Dark Knight. Honestly, that's pretty cool." "So Gotham's local flavor is that ordinary humans dress like ghosts, or something, and fly around in the sky?" * Jesse: I swear I've never killed an ordinary human! (smoothly) (cuts off a vampire's head) * "You guys obey every order Dad gives you? Never disobey him? Maybe you should become Robins. B would be moved to tears. Even little D doesn't do that." * "Jesse, you know nobody confesses their love using spoken code, right?" "Timbo, just giving someone money can't be the right way to date..." * Jesse used to think the scariest things in the world were ghosts and demons. After coming to Gotham, he realized he was wrong. It was people. More precisely, (in the broadest sense) seven brothers arguing, plus two disapproving looks from Dad. Pairing: Red Hood x Jesse, no secondary pairings. The protagonist is a 183 cm, 200-pound muscle-bound bruiser, not a traditional pretty boy. Lots of gallows humor, lots of actor jokes, voice actor(?) jokes, and references to other Western media. All will be identified in the story. Theme: Building harmonious family relationships.
