[Crossover X Onmyoji] Why Did My Lost Shikigami Become a Special-Grade Cursed Spirit?

Even with a smaller body, her mind is still sharp and her movements still agile (or so she claims). Today, as always, this young Onmyoji player is running all over the place looking for her missing shikigami. Scene One: Ibuki (lying flat): No slacking, meow. Go earn money and buy me dried fish! Girl: Heh... What kind of System is this? More like some spoiled lordling. Poor me, I've lost my shikigami and my job, and now I'm reliving bald-inducing geometry functions just to play a game. Can you act like a person for once? Scene Two: Girl (pointing at a black, shapeless blob): You said the thing running around over there was my Kimen, so who's that girl squatting on the ground and crying? Ibuki (licking his paw): Isn't that Kimen? She only lost her mask. Hurry up. No slacking when my dried fish are at stake! Ever since someone arrived in this world, the streets of the Jujutsu world have been filled with curses and all sorts of strange things, making life even harder for the already understaffed Jujutsu High. Scene Three: Aoi (striking a pose): What's your type? Girl [30+ years old across two lifetimes, posing as a young girl]: Me? At least older than me. I don't have any other particular requirements... I guess it depends on the feeling. The 16-year-old pink-haired and black-haired high school boys, the reliable 27-year-old corporate drone, the 28-year-old unhinged teacher, and the King of Curses, who's lost a finger, all pull out notebooks at the same time. Ibuki, who knows too much: I think everyone except the last one is going to get rejected. Everyone: ??? Content warnings: This is a crossover quick transmigration story. The early part is mainly set in the Jujutsu Kaisen world. The girl comes with an Onmyoji System. There is OOC, and the author may be proven wrong. The heroine is overpowered and has a great time. The main story features multiple love interests. Please don't offer writing advice in the comments. Crossover worlds: Jujutsu Kaisen, Inuyasha, The Kitaro of the Graveyard and other classic anime (more will be added later). Theme: An Onmyoji player races to the front lines of battle to get home.
