[Mostly Jujutsu Kaisen] Wearing an OC's Secret Identity in the Jujutsu Kaisen World

You were once a creator of Jujutsu Kaisen OCs. Then one day, you transmigrated. You realized you couldn't remember anything, and somehow ended up in the world of Jujutsu Kaisen. You: *makes a questioning noise.jpg* With no preparation at all, you put on the secret identities of the many OCs you'd made in the past. Relying on the memories attached to each identity (that is, the settings and plotlines you'd come up with), you tried to make up for the regrets you remembered in this world. At first, your secret identities were in different worlds. But the nth time you used one, you discovered that your past self had already dug the trap and was just waiting for you to fall in. :) You: MMP! Did you hear me? MMP! * No CP. You're forever single. * There may be grudges between your secret identities, as well as tangled history between them and the characters. * There will be OOC, OOC, OOC. The main setting is Jujutsu Kaisen, though characters from other series may wander in (such as Bungo Stray Dogs, Touken Ranbu, and so on). * Mainly second person, with occasional passages in third and first person. * Lots of foreshadowing (probably). * Updates when inspiration strikes. Updates when inspiration strikes. * No identity reveals. Really, no identity reveals, since you're just playing yourself. :) Theme: Making up for some regrets
