Muzan, Devour My Three-Legged Golden Crow!

The Flame Hashira found a strange little bird. Three legs, a crow, its feathers as golden as the sun. The golden little bird was covered in wounds and barely breathing. The Flame Hashira found a veterinarian to bandage its wounds. When he turned around, the bird transformed into a person right before his eyes. The Flame Hashira: "..." Umm! Lu Ya, the Tenth Prince of the Demon Tribe, was out for a stroll one day when he stepped into thin air, tumbled into a space-time rift, and landed in an unfamiliar world, covered in injuries. Fortunately, he met a human who looked just like an owl demon and came to his aid. Lu Ya: "Good. I'll repay the favor before I leave." On a mission, the Flame Hashira turns around and takes him aboard the Mugen Train. Lu Ya casually breaks the spell on his ticket and watches the Demon Slayer Corps slay demons. At the end, an Upper Rank Three jumps out beside the train and tries to talk our upstanding young man into joining him. Lu Ya, Tenth Prince of the Demon Tribe, son of Dijun, the true sun: How could I put up with that??? PS: 1. No pairing, Muzan gets killed. Ultimate wish-fulfillment story, everything is for a happy ending. 2. [Headcanon everywhere] [Headcanon everywhere] [Headcanon everywhere] (important things are said three times). Any out-of-character behavior is the author's responsibility. 3. I've already discussed and reached an agreement with my editor. It will be released on January 8, a Sunday. [Important] In mythology, the three-legged Golden Crow is a black three-legged crow in the center of the red sun. In this story, the three-legged Golden Crow is literally a "Golden Crow." Please don't confuse it with the original mythology. A preview of "Yokohama Simulation Game" Kozume Asu was randomly selected online for a beta-testing spot in a single-player game called "Life Simulation in Another World." Thrilled to try a full-dive game for the first time, Kozume Asu said, "Awesome!" Then she was shot in the head as soon as she entered the game. Kozume Asu: ... Although Kozume Asu suffered three different deaths on her first day in the game: getting shot in the head, stabbed in the back, and murdered, she still diligently became a player focused on construction. Generally speaking, the defining trait of construction and farming players is: if you won't let me build things, I'll plant you in the fields. So Kozume Asu diligently planted a local kingpin, a troublesome kid, and an antisocial criminal in her fields, one after another. Local kingpin: "...Can we talk this over? I can go back home and farm." Troublesome kid's backer: "...Seriously? You can get me into school?" Antisocial criminal: "...Ah." PS: 1. The synopsis may be revised, but the basic premise won't change. No pairing, all relationships are platonic. 2. A crossover between Bungo Stray Dogs and Haikyuu!!. Haikyuu!! takes place in the real world, while Bungo Stray Dogs is a game world accessed remotely. Both worlds are real. The worlds do not merge. 3. A fun, everyday-life story with a happy ending.
