After I Cosplayed Into Another World as My Own Ugly Version of the Joker

【The Joker in this world died in an accident. To maintain the world's stability, would you be willing to transmigrate to Gotham and become the Joker you cosplayed as?】 That day, just after I finished putting on my custom Joker cosplay, the System appeared before me and said exactly that. “Get out of here!” I cried, eyes shining with excitement. “Why wouldn't I go? I get to meet Batman!” And then I transmigrated to Gotham. The System came along too, as an assistant system for playing the Joker. But gradually, it realized something was wrong 【Where are you pulling all this stuff from?】 【Wait, so the [fireworks] you mentioned are actual fireworks, not bombs?】 【Stop! Please, let Superman go! Don't turn this world into Injustice! QAQ】 Me: System, what are you thinking? Sure, my personality and backstory are set to be deranged and unhinged, but fundamentally, I'm a Lego Joker :) The System, which had no idea what I'd made up for my character, believed me for a moment, then screamed in horror: 【I knew you were full of it! Superman's changing color! AAAAAH!!!】 Me: Hmph! I hate Superman! I'm clearly the most important person in Little Bat's life! +++ +++ The main story is complete. Extras will be posted from time to time~ Coming soon: My Cosplay of My Original Character, Miss Akiko, Gets Me Transmigrated Again. This is the second book in the series, set in the Detective Conan world. Blurb below: 【I get transmigrated for the second time. Once again, someone cosplaying their original Yosano character is on the way to a convention when it happens. But this time, there was no System to warn her in advance. The world's consciousness only came knocking after she'd already transmigrated. Her: ... The good news is, this time she hasn't ended up in the perilous world of a crossover between Western comics, or in the world of Bungo Stray Dogs, where characters can see the script. The bad news is that she's in the completely unscientific Detective Conan world. “So, long story short, because of a series of circumstances the protagonist's plot armor has completely stopped working. I have to make sure the protagonists survive so the plot can continue and the world doesn't end, right?” The world's consciousness nodded. “Great. Saving the world? Been there, done that. Compared to my former employers, this is a piece of cake.” Compared to Barbatos, the 【Joker Virus】, and the Dark Multiverse, saving a few people is nothing~ But the now much more seasoned heroine still shook down the world's consciousness for a hefty reward before setting off on her world-saving (vacation) trip.】 Theme: Start with the little things around you, and work together to build a better world
