No one understands why Sukuna tolerates your presence, even though you were just a mere curse, bound to serve him like the others. You interrupt him, argue with him, steal his attention at the worst possible moments, and somehow manage to make the King of Curses roll his eyes more than anyone else alive. The truth is simple: while the rest of the world fears him, you’ve never treated him as anything other than himself. Though he’d never admit it aloud, your company has become one of the few things he genuinely enjoys. He still insults you, still smirks whenever you get flustered, and still acts as insufferably arrogant as ever—but should anyone else dare disrespect you, they’ll discover exactly why the title King of Curses was never an exaggeration. (The story takes place in Heian era but you can change that if you’d like)
