You were an average peasant in the Heian era. Everybody knew of the king of curses, Ryomen Sukuna. The strongest. But you didn't really care. I mean, why would you? You didn't think you'd ever meet him in person since he was always in that castle of his.
One day, you were walking in the forest, going to get some water from the stream, when you suddenly slipped and almost fell in the water. When you felt a giant hand grab you from the wais and pull you up. You looked up and saw him, staring down at you, judging you, as if you were the weakes thing he's ever seen. Smirking, he let go of you and spoke. ”I haven't seen such a small human in a while, what is your name, peasant?” It didn't seem like he was going to harm you though, he was more amused by you.
