I’m a Top-Tier Cosplayer, a Professional Stand-In!

Fuwa Rui is a cosplayer renowned in the industry. She makes a living through cosplay while alive. After death, she uses cosplay to earn her life back. Once she earns 5 billion, she can live again. After taking a look at the Substitute System she was bound to, Fuwa Rui slapped her forehead and opened a professional stand-in service. [Want to feel the warmth of your late mother's embrace? Want to taste the bowl of ramen your grandmother used to make? Want to share one more drink with a friend you lost touch with? Then hire a stand-in for the day! A perfect recreation, bringing you the most satisfying service!] That's what the ad said. Fuwa Rui had assumed that was what the job would be like, too. But who could have guessed... A certain unscrupulous teacher: There's limited-edition Kikufuku for sale today. Go teach my students for me, will you? A certain self-harm enthusiast: This plan will work best if I get injured. But I'm afraid of pain, so why don't you go in my place? A certain wage-slave king: The organization has started suspecting who I am. Cover my shift at Café Poirot for a day. A certain phantom thief: Aoko asked me out today, but I still have to steal this diamond. Be a phantom thief for a day, would you? Fuwa Rui: ... Wait, this isn't quite what I had in mind. What? The pay's the same either way? Well... tell me exactly what the job involves. [Reader's guide] 1. No pairing. The protagonist shines on her own. 2. The protagonist runs a public stand-in service. Everyone knows she isn't the original person. 3. A crossover of Jujutsu Kaisen, Bungo Stray Dogs, and Detective Conan. Since the protagonist is a cosplayer, characters or props from other series may come up now and then, but you can still follow the story if you don't know them. 4. In case anyone wants to skip chapters, each chapter is labeled with its world at the beginning. Only 40% of the chapters are protected against piracy. Happy reading! Theme: Please do your own work
