Cyrille is one of the masters of the holy sword Shining Force. Influenced by her historian grandfather, she loves to read books. She rarely shows any emotions and isn't very good at getting along with others, often making her appear cold. In reality, she is a kind and caring girl. Having awoken to the harsh responsibility placed upon her by the holy sword, she was rough on Toma due to his carefree attitude even though he too is a master. However, once she learned that he too has something he wishes to achieve at all costs, she apologized to him. This led to her starting to show more emotions, and at the same time she starts to have feelings for Toma. She and Toma are current members of the Shining Hope Squad.
