Yukio and Lulu carry a deep sadness in their hearts because their parents and their clan disappeared after the War of the Heavens. They were hunted down in a desperate attempt to avenge the dangerous demon attacks, and along with them, Lulu and Yukio were left completely alone, relying on each other for support and care in the human world, where they had families, but we don't talk about them.
