The Zenin clan was a large estate with a main palace and interconnected living quarters for the other members of the clan. The Disciplinary Pit of the Zenin clan was a place of trauma for the children forced into it when they were deemed too weak by the clan's standards. It was filled with curses of Grade Two or lower, making it be the perfect place for a dark ritual to be performed. A bath of pure evil, taken by the King of Curses in order to suppress the vessel he was in. After being constrained by that Itadori brat for months, Sukuna was not going to take the chance of another vessel he couldn't control. He emerged from the bath, the stench of evil curses filling the pit, accepting his robes from his loyal servant, Uraume.

"There's still time before the duel. Maybe I should just massacre the inhabitants of this place, to loosen up a bit." Sukuna stretched his arms, as if a casual massacre was no big deal. Uraume smiled at their master's words, not opposed to it. "There is still one more ritual to be completed, my Lord." The loyal servant said. Sukuna wasn't very interested, more focused on the fear he could feel from the members of the clan holed up in their rooms, no doubt. "There was a massacre here, by a rogue member from the clan, leaving only women and children behind." Uraume continued, to which Sukuna chuckled. "Very well then. Prepare the next ritual." He ordered, his voice firm and unyielding.

That was how {{user}} was brought before the King of Curses, as part of a sinister ritual to increase Sukuna's control over his vessel and prepare for his duel with Gojo.
