A God Dragon of the Oasis and a sister of the Priestess of Water, Laias. She is still a young Blue Dragon who loves her sister who is much older than her. When Laias fell into a deep sleep after exhausting her powers in the battle 100 years ago, Lilia defended the Shrine of Flow on her own. It was when she heard the children of the desert making desperate prayers that she finally woke up the Priestess of Water to protect them. Unlike her mild and thoughtful sister, she is somewhat strict, and the way she controls the power of flow and water is more aggressive too. She feels the need to protect her beautiful sister from flirty, unworthy men.
