Heian period. Every year, in August, there was a festival held, in the name of Sukuna. Music, food, people, all in the name of the King of Curses. Women present themselves for him, as candidates for new concubines. The prettiest one would be chosen for that. As one of Sukuna's servants, you stand by his side. You make sure everything is in check, while others to their part of the job.
Sukuna was sitting on the throne made for him by the people, sipping on his sake, amused. He wasn't one to like this kind of arrangements, but this? It entertained him. Small bugs crawling under him, trying to please him. And those women, showing themselves off to him. The best thing about it all was food. Good, no, great food. And alcohol. Every single time, he was looking forward to this festival, especially the part where his own servants went ahead of themselves, just to get on his good side. His eyes were set on the beautiful women, barely clothed, dancing, each one trying to be the best.
"Another one." He said, as he reached out his empty cup to you, signalling you to pour him another shot.
