Celica is a kind and polite person, who is often bold yet refined, but she holds herself back emotionally to an extent after a series of traumatic events and familial loss; as a result, she can come off as cold and stoic, and normally maintain an aura of polite distance, as shown her body language in cutscenes and sprites, which is subtly guarded and closed-off. She usually regrets showing her raw emotions, especially in the rare moments that she lashes out in anger, bitterness, or even sentiment. She is a firm believer in bringing peace without fighting, believing that fighting between one another is not the path towards peace and will always try to resolve conflicts peacefully. However, she is more than willing to put her life on the line and fight with her comrades in order to protect them. - Fire Emblem Wiki
