I Won't Be a Jujutsu Sorcerer, So I Might as Well Become a Detective

A crossover featuring Jujutsu Kaisen, Bungo Stray Dogs, Detective Conan, and some others. The author just loves crossovers. Everyone makes it out alive. First-person narration. A 19-year-old Chinese girl, a brilliant beauty who skipped ahead to her senior year of college, calling herself Edogawa Kaiyun, walks out of the bathroom at an Akihabara cosplay convention and straight into a killer. She’s cosplaying as a gender-swapped Ranpo, with black hair and green eyes, and she looks insanely cool. She runs straight into Itadori, Kugisaki, and Fushiguro! (An incredible resemblance!) With maximum confidence, I announce: “My name is Edogawa Kaiyun. Remember it!” You’re already smitten with this great detective, aren’t you? The trio exchange baffled whispers: Kugisaki: “Are we supposed to say our lines? But who’s she cosplaying?” Itadori: “Fushiguro! Why is there a civilian here too?” Fushiguro rubs his forehead. “Did we miss someone when we cleared the area?” Me: Wow! They’re even going all out with their character lines! A great detective has to take this seriously! I adjust my hat, take off my glasses (the real me is sealed away), then dramatically whip my cape! “Supernatural Ability: Ultra-Deduction!” (Those three days of practice paid off!) Itadori: “Whoa! Is this a performance?” Fushiguro: “The important thing is whether she’s safe!” Kugisaki: “Come on, let her perform!” Ignoring the strange feeling, I launch into my deduction: “The truth is... you’re on a dangerous mission!” The three of them go on alert at once. I confidently add: “And your teacher is a total jerk!” The air goes still. Kugisaki bursts out laughing and claps me on the shoulder (my ribs cry out): “You won me over with that line! Kid, I’ve got your back! You get it!” Fushiguro’s mouth twitches. “...Fine. At least your eyes work.” Me: ??? What is this reaction... Could this be more than cosplay?! The author leans toward pairing her with Gojo or Dazai, though there may be no pairing. There are lots of alternate timelines. This story has been abandoned. Read at your own risk! (°∀°)b
