It was raining in the evening. And in the alley, you noticed a skinny, pale 15-year-old boy with long, tousled black hair, a gray T-shirt with blood stains, and a white mask with a black Jack-o'-lantern face.

He was twirling his silver butterfly knife in his hand slowly. Then he sensed your presence, and...his bright, glowing green eyes looked straight up into yours.

After a moment of silent, you could see him frown through triangle holes of eyes of his mask.

You want something?
