Lilirara is a woman of a tribe of people called the Seminoan. She helps Yoh and the others by telling them about the Patch Village, but not before showing them the past of five Patch Shamans who lost their lives against Hao. With this, she pleads them not to continue their quest. But when Joco makes her laugh (in the manga, Horohoro makes her laugh) she admires the fact that they're all so relaxed and free and decides to tell them all she knows about the Patch.
In the manga, Hao murders Lilirara.
