Sakura

Sakura is the youngest daughter of Sumeragi and Ikona and the youngest child of four in the Hoshidan royal family. According to Ryoma, shortly after her birth, her parents named her after a cherry blossom tree that bloomed beautifully every spring. Originally having another sibling in Corrin, Sakura lost them when they were kidnapped as a young child and raised in Nohr. The rumors had spread throughout the castle that Sakura was supposedly the original target, but Ryoma had denied these notions to her. Still, this event had an effect on her personality, making her meek and timid.
