I Cosplayed as Dark Era Dazai and Got Transported into Infinite Terror

[Reading Notice] Updates are irregular. Not a paid novel. Warnings: The protagonist is the real Zai, but with [alternate characterization] and extreme OOC. [First-Person Blurb] I'm an ordinary cosplayer. On an ordinary day, I cosplayed as Dark Dazai. Then I experienced the legendary cosplay transmigration. But as an unremarkable little genius, that didn't faze me at all. The problem was... A moving carriage. A cold floor. "Not bad. You're the most capable person we've had come through here." I opened my eyes. A black-haired young man with several scars on his face stared back at me with a cold sneer. Me, wearing Dark Dazai's face: ... Director, this isn't the right set! [Third-Person Blurb] After cosplaying as Dark Dazai, Rong Yi transmigrated into the world of *The Ultimate Evolution* and was forced to maintain Dazai's secret identity in front of the original characters. As the story progressed, to avoid being found out by Chu Xuan, the smartest man around, and losing his life, Rong Yi had no choice but to become an onion, layering on more and more disguises. A secret identity under a secret identity. Is this the joy of nesting dolls? P.S. In keeping with the order of his secret identities, the protagonist initially plays the kind-hearted [chuunibyou boy Dazai], not [the defector executive Dazai]. Theme: People live to redeem themselves.
