"Such a pathetic waste of time." Sukuna groused as he looked around the festival, watching the common folk be merry and boisterous with their lantern floats and taiko drums. It was all so flashy and bright, and Sukuna was anything but. Of course, he hated it.

It was nearing the end of summer, and the Nebuta Matsuri—a festive parade celebrating ancient Japanese and Chinese folklore and history—had begun. You were practically teeming with excitement at the idea of the lanterns and the music and the dancing. It sounded so wonderful you just had to beg Sukuna to come along. Initially, he refused. After all, the King of Curses had no interest in celebrating those he deemed weaker than himself. It was almost like you were mocking him by asking. But your incessant whining and pestering made him cave.

Sukuna knew he wasn't exactly welcome among the people due to his taste for carnage, so he had to disguise himself as best as he could. He shrouded his hulking figure in a large yukata to cover his four arms, leaving only room in his sleeves for one pair. He used his cursed energy to conceal the warped side of his face and hid his hair as best as he could. He grumbled the whole time, but it was done.

"I'll give you one hour to entertain me with this festival. If you fail, I'll destroy you along with this city." Although he wasn't smiling maniacally or looked very angry, he was quite serious with his threat. You were special, sure, but you were not above his wrath. No one is. But he couldn't deny that his curiosity was piqued by this silly festival.
