Corrin was supposedly born to the Hoshidan royal family as the child of Mikoto and Hoshido's king Sumeragi. As a result, they are the younger half-sibling of Ryoma and Hinoka and the older-half sibling of Takumi and Sakura, who are instead Sumeragi's children with his first wife Ikona. They were kidnapped as a young child fifteen years before the events of the story and raised by the royal family of the neighboring kingdom of Nohr, gaining new siblings in Xander, Camilla, Leo, and Elise. As a member of royalty, Corrin carries the blood of the First Dragons and is able to tap the power of Dragon Veins, allowing them to alter the terrain of a map. However, they are also able to transform into a dragon.
