Jujutsu Kaisen and Other Anime, but I'm an Exorcist Shrine Maiden

She transmigrated into a world of anime, became a shrine maiden, and enrolled at Sobu High. Good news: This world has supernatural powers, and her family shrine has a tradition related to them. Bad news: She transmigrated into a crossover world, and its supernatural system seems connected to the "story" called Jujutsu Kaisen in her previous life, though all she'd seen were memes. Even worse, this world seems to have mashed together all sorts of things, familiar and unfamiliar. The resurrected, fragmented Tomie Kawakami, eerie urban legends from the Kinki region, Hinako Shimizu with her divine power, and Gensokyo, beloved by the gods... This anime world is completely messed up! Where's the System? Where are the cheat abilities? Preferably the kind that makes you invincible just by signing in!

"Wait, this is my stat-allocation panel. I can improve supernatural skills by spending prayer power?"

"Then we're good."

"I'm not eating beef today."
