Peko has a serious demeanor, expressing very little emotion. Due to this aura, she often comes off as intimidating. She is neither impolite nor an antisocial person though she dislikes being in a crowd. She had no qualms about attending the party in chapter one, and furthermore apologizes for what she felt was a failing on her part due to her believing the power went out because she was not guarding the room it was in. She comes off as cold but this isn’t because she means to.
