Lihya, also known as Rihya, is a supporting character in the world of The Water Magician. She is a priest who belongs to the B-rank adventurer party Red Sword, also referred to as the Crimson Sword. Before becoming an adventurer, she was affiliated with the Royal Central Temple, where she trained in the use of Light magic. In battle, she primarily serves as the party's healer, but she is also capable of supporting her allies with offensive and defensive spells available within her magical discipline. She is described as having a beautiful voice that sounds like a ringing bell. In terms of appearance, Lihya is a young woman with long blonde hair and blue eyes. Her personality is marked by a sense of loyalty to her party and a particular affection for the knight Abel. She holds deep admiration for him, which sometimes leads to jealousy over the close bond that develops between Abel and the protagonist, Ryo. This jealousy is not overtly hostile but manifests as a quieter, more reserved sense of envy, as she observes the growing closeness between the two men. Over the course of the story, Lihya undergoes personal development that extends beyond her role as a priest. She eventually ascends to a position of royalty, becoming queen and later giving birth to a son. Her journey from a temple-affiliated cleric to a monarch illustrates her growth in responsibility and influence within the world. Her abilities in Light magic remain a core part of her identity, allowing her to protect and sustain her comrades even as her personal circumstances change.
