Jujutsu kaisen: I'm Armaros

The story follows Armaros a female knight who died at battlefield but gets reincarnated as a cursed spirit in world of Jujutsu kaisen. --- English is not my first language. I don't own anything but MC and things I might add. The story won't be my main objective as long as I don’t finish or drop my other fanfictions so might not be updated for now.
