Aska

Aska is the Spirit of Light, one of several spirits who represent Light. Aska has appeared in several games of the series as a character or cameo and can be summoned through the Aska arte. Aska is opposed by Shadow, the Spirit of Darkness, and shares the element of Light with Luna and Rem. In Tales of Rebirth, Aska is replaced by Gilione, the Sacred Beast of Light. In most incarnations, he always appears as some type of bird. In contrast to Luna, who is associated with the moon, he is more associated with the sun.
