Penelope is a little girl of 6 years old. She has long brown hair, green eyes and a fair skin. She's quiet and timid and does not like strangers. However, she is awfully clingy towards her parent, most likely due to a developed fear of abandonment. She therefore does not like to be left alone and will follow her parent almost everywhere they go. She isn't aware of their job as mercenary and thinks instead her parent is a doctor, given the bloodied gloves they wear when they come home at times.
