Cyrille is much the opposite of Toma in many ways. While Toma could be considered the "temperamental barbarian boy", Cyrille is the "calm educated girl". Not much is known about her family other than her grandfather, but she received a highly prestigious education when she lived in the Noswald Empire, one of the two factions at war in Shining Force EXA. Thanks to extensive researching and a gifted mind, she mastered the magic arts at a young age and can wield a variety of spells at once, making her quite formidable on the battlefield. It is also not known at what point Toma and Cyrille met before the events of their game began, but she teamed up with him when she learned Toma was seeking the legendary holy sword, Shining Force. She too was seeking it, but for a mysterious reason she kept from the rest of the party. Toma managed to acquire it before she did at the very beginning of the story, and Cyrille remained with him to make sure he understood the responsibilities that came with wielding such a coveted item.
