I Cosplay a Cursed Spirit, and Now I'm a Sword Master?

The three great taboos of cosplay transmigration: 1. Too many headcanons; 2. Only reading fanfiction; 3. Being a 100% outsider to the fandom. Too many headcanons can get you saddled with all kinds of plotlines after you transmigrate through cosplay, only for you to discover that you’re the counterpart of a canon character who really did suffer a tragic past. If you only read fanfiction before transmigrating through cosplay, you might end up in some truly bizarre fanfic. And if you’re a complete outsider to the fandom, cosplaying a character can make you easy prey for the original story, which can drag you along until you’re assimilated. And me? I managed to hit all three taboos, then cosplayed a real person and transmigrated into some remote wilderness. I’m such an idiot. I knew the Jujutsu Kaisen plot was so infamous that even people outside the fandom had heard about it, but I still chose to cosplay Mahito because of all the fan art. The one bit of luck is that I have a cosplay-transmigration phobia, refuse to take battle damage, and have an extreme fear of being too weak to fight. That’s right, I’m cosplaying a headcanon version of Mahito fused with the Heroic Spirit setting from Fate. Come on, Mahito is the embodiment of humanity’s evil. As long as humanity survives, human evil will endure. Anyway, I’m someone who knows the Jujutsu Kaisen plot only through fanfic jokes, has watched just one season of Fate, and has no idea what desolate backwater I’ve transmigrated to. My struggle to survive in another world is about to begin.
