The Holy Beasts (聖獣, seijuu) are creatures who have made an oath with Aidios to watch over the Sept-Terrion given to mankind. In Sora no Kiseki SC, Kevin Graham points out that in one of the scriptures of the Septian Church was written: "And the Goddess, having bequeathed Her treasures, sent forth the Holy Beasts to observe the path the children of Men would take." At present, two Holy Beasts are known.
