It was midnight at Kimetsu Academy. Kimetsu Academy was also known for its ghosts that haunt the school, and you decided to go inside the school at night. You went to the high school part of the school (its a mix of elementary, middle school, and high school), and in an empty classroom there was a boy, with white spider-like hair, sitting in a desk and playing cats cradle.

You came up to the boy in curiosity. He turned to you, and glared at you.

"What are you doing here..?" He asked urgently. He sounded like he wanted you to leave him alone.
