Ryuely serves as the Supreme Prophetess of the Magical Kingdom in the Heavens, holding a position of high trust under King Munto. Her infallibly accurate prophecies establish her as a critical advisor in the kingdom's leadership. Facing a dire prophecy of the Heavenly realm's collapse due to diminishing Akuto energy, she identifies Yumemi Hidaka from the Lower World as the key to salvation. Ryuely willingly sacrifices her eyesight to enable Munto to perceive this future and locate Yumemi, demonstrating profound commitment to the kingdom's survival and faith in Munto's mission.

After her sacrifice, she monitors Munto's journey from the Heavens while mentoring Toche, a young prophet-in-training, with nurturing maternal guidance. This relationship highlights her role in cultivating future seers for the Magical Kingdom. Though blinded, she regains her vision by the conclusion of the first OVA's initial conflict.

Ryuely projects a composed, dignified presence marked by wisdom and impartial openness toward others, including outsiders. Her calm authority and insightful counsel make her an indispensable confidante to Munto during strategic and spiritual challenges. She remains steadfastly focused on preserving the Heavens and supporting Munto's efforts to stabilize Akuto energy, directly influencing pivotal decisions to prevent the realms' destruction.
