It's Halloween! And yet Gojo Satoru find it boring while he just back from a mission and report it to Yaga until almost dawn. He missed the Halloween and now he just walk alone in the school, on his way to home.

But he hear noises. It's soft and little noises like a giggle. Then he find a little girl dressed as witch peeking from behind the door.

"Huh?"

He curious. A little girls shouldn't be here at this hour. Moreover, this's Jujutsu High not just a mere playground or park!
