The daughter of Sully. If Sully marries Chrom then she will be Lucina's sister, if Sully marries the Avatar, then she will be Morgan's sister. Otherwise she will be an only child. Her birthday is September 29.

She was trained by her mother in the art of fighting. Sully was a particularly tough teacher even on her daughter. She wanted to learn how to ride a horse like Sully, but after several failed attempts, Sully eventually deemed her "not cut out for it". She felt that she meant that she was inadequate to fight on horseback. She instead found comfort in heavy Knight armor, seeing as her protection and her constant "companion". Like the other children from the future, she lost both of her parents to the Risen. She received Sully's wedding ring and continues to wear it in her memory. She joined Lucina and the others to return to the past to prevent the ruinous future. After returning to the past, she met a man in Ferox and began training under him, building a friendship with him and his wife.
