Peko comes off as a very serious and stern woman who shows little to no emotions. Despite her authoritative tone, she is respectful of authority figures and does not police the other students. She also loses track of time when practicing martial arts, but she is not antisocial or unwilling to stay around the other students. It also revealed that she was not able to smile because she thought she never really needed to smile. Over time, because she completely neglected it, she eventually forgot how to smile. She wants to make her childhood friend smile again, so she has a strong motivation to able herself to smile. Eventually, she learns that, “Smiling is not something you have to force. When your heart gets warm, smiles come to you naturally.”
