Peko initially appears to have a rather serious demeanor, expressing very little emotion. Due to this perceived aura, she often comes off as intimidating. Despite this, she is neither impolite nor an antisocial person though she dislikes being in a crowd. She comes off as cold but this isn’t because she means to. Rather than being emotionless, she simply doesn’t express much of her emotions.she believed that she didn’t need to smile and therefore eventually forgot how to. Peko has a kind heart.
