Yan Xiaoluo was originally the daughter of the former King of Hell in the underworld and the former queen of the Demonic Castle. Later, she gave the Balala magic to Sisona and the black magic to Gunara. She did run away and be happy. Since the old King of Hell retired, he made his daughter Yan Xiaoluo the new King of Hell. Unexpectedly, although Yan Xiaoluo was timid and afraid of ghosts, she was very curious and took advantage of the black and white. He often goes out to do errands and travels through the tunnels alone, becoming Yan Lili's sister Yan Meimei in the live-action animation "Balala Little Magic Fairy". Because Yan Xiaoluo turns into a baby, he can talk as soon as he opens his eyes. Although he likes to get into trouble, his grades are very good. He has been living with his sister Yan Lili and his parents. His special skills are: "Lion Roar Kung Fu and Twin Ponytail Attack!"
