A girl with blonde hair and sapphire-blue eyes. A character from Ken-Asu and the Princess of the Asteria Kingdom, the homeland of Ryuo and Erin. She possesses great magical talent, particularly in sensory perception. She can use prophecy magic, though it is difficult to control and remains imperfect. Having received a prophecy regarding the Demon King's resurrection, she is doing everything in her power to prepare. (However, she was unable to detect the presence of Sana and Guest, who originally exist outside the game.) She appointed Ryuo as a Hero after he drew the Sword of Selection (Falias).

A character from Ken-Asu, she is a demon girl possessing powerful magical energy. She masters magic attacks of various attributes, earning her the epithet "Elba of the Mad Rhapsody" due to her multi-layered magical assaults. While she has a somewhat strong-willed personality, she is sensitive and kind at heart. Because she won a magic tournament in the Demon Realm, she holds the title of one of the Demon King's Four Heavenly Kings, but she doesn't actually want to fight humans (as it was a human who helped her when she was a helpless orphan). She is ostensibly hostile toward Ryuo. Behind the scenes, she frees enslaved children, repels corrupt adults, and protects orphaned children.
