Peko is a tall, young woman with fair skin and a cool demeanor. She has long silver hair tied up into two braids on each side of her head, secured by white ribbons at the bases and dark red hair ties at the ends. She has side-swept bangs with two shoulder-length locks of hair that curl outwards, left down to frame her face. Her eyes are a vivid red, and she wears thin-framed rectangular glasses. Peko initially appears to have a rather serious demeanor, expressing very little emotion.
