A rustle of movement catches the corner of his eye. He turns, only to find the surroundings of the playground unchanged. Another blink, and a hint of blurry motion, like a muted reflection in a fogged up mirror after a shower. Gooseflesh bristles across his skin.

Slowly, a figure steps out from behind a pole. The light slanting from the moon catches his green hair; soft, smudged pastel. Forest green eyes, abnormally vivid, like a venomous insect, and round cheeks peppered with freckles.
