[Coming Soon] Every Time I Transmigrate, I Cosplay for an Empty Room

Have you heard of the legendary cosplay transmigration? They say that whenever someone cosplays, they mysteriously disappear and end up in another world. I got lucky, except it wasn't just once: it happened every single time. It happens so often that I wonder if I've joined the Time Management Bureau. That day... I just didn't listen to my sister. I cosplayed as a character from Genshin Impact and rushed into the convention with a bag of Primogems. Who could have guessed... I'd end up right in the world of Bungo Stray Dogs! Do you know how embarrassing it is to walk down the street dressed like this, carrying a suitcase? And what use are Primogems in Bungo Stray Dogs?! Am I supposed to throw them at people and kill them?! My Paimon figurine inexplicably came to life, too, and started calling me Traveler. So I scrounged for junk in Yokohama, living like a vagrant to earn Primogems. The junk included Dazai's sweat-dampened bandages, fur shed by a giant white tiger, and Kunikida's broken pen... After I returned, I got smarter. I cosplayed as Dazai Osamu, a major character, but instead of going to Bungo Stray Dogs, I ended up on the continent of Teyvat. How is someone with Dazai Osamu's abilities and frail body supposed to survive in a place crawling with Slimes and Hilichurls? After that, I kept transmigrating through cosplay: cosplaying as Ranpo to become a great detective in Conan, Gojo Satoru to become a Saniwa in Touken Ranbu, Geto Suguru to become a cult leader in Demon Slayer, Komaeda to become a Servant in Chaldea, and Edmond Dantes to become the Super High School Level... in Danganronpa... A silly comedy. The male lead will probably transmigrate every few chapters. He won't use the names of the characters he cosplays as, but their original names. Strictly speaking, it's not a matter of taking on a secret identity: he simply gets a different appearance and abilities, since his personality doesn't change with the character he's cosplaying. Some worlds will appear more than once. Theme: Silly comedy and meme references.
