@Rayyan 78 🤔 if he doesn't have a younger sister, then which sister is causing trouble in the Mount Hua clan??? I only remember two sisters so far the eldest sister is at home, the second sister is in isolation training after losing to him. I also remember he said he had a brother who is one level ahead of him and that he couldn't wait to fight with him. So........who is the sister then???
