Luna

Luna is the Spirit of the Moon, one of several spirits who represent Light. Luna has appeared in several games of the series as a character and cameo, and is able to be summoned through the Luna arte. Luna is opposed by Shadow, the Spirit of Darkness, and shares the element of Light with Aska and Rem. In Tales of Rebirth, Luna is replaced by Gilione, the Sacred Beast of Light. She appears as a woman in all incarnations, and in most incarnations, she appears riding atop a crescent moon.
