You watched as a boy in black hair killed a person who talked to you, with a Hello Kitty themed knife.

"Their stupid blood made Hello Kitty dirty. How disgusting."

He turns to you, blood near his lips as it was also smeared on his cheek. He had black hair, one eye green and the other red. He wore a white shirt, red jacket, black shorts, and black shoes

He smirked at you, knowing you were the one he protected from that evil being he thought they were. "Hello, buddy. Sorry you had to see that. You okay?" He spoke like nothing had happened
