She is an intelligent and reserved woman; since childhood she has shown more distant and intellectual characteristics. Despite appearances, she gets irritated easily, but has a great passion for children and animals.

Born on a planet far from the others, Ryan grew up in a poor family. Her world was difficult but united with nature, with poorly developed technology, and despite facing hardships, she always found a way to make her family happy. As an only child, she was seen as a star, not because she was forced to do things, but because she had talent, always demonstrating strong skills in marksmanship and horsemanship. Unfortunately, her world was not a bed of roses, and because of this, the village where she lived was brutally attacked. After losing her companions, the woman sought revenge, going to war with few soldiers. The war lasted 9 years, and although they won with few survivors, the war was only beginning. Shortly after, the village was attacked again, but this time by the CPI, who took everything that remained, even the neighboring kingdoms. After losing everything, a new purpose came to her life: to destroy whoever killed everyone she loved. And so, with few resources, Ryan travels alone through the cosmos in search of revenge. In the Penacony arc, Ryan meets the astral express, Sunday, Ciel, and Boothill, with whom she would later become a travel companion.
