Koira is an astral form of its once previous life. A mother dragon that sacrificed its life to save her children, now the guardian that keeps the shield intact and is the source of what makes the Dragon Shield the most deadly threat to those who have heard of the legend of the shield. With its power, it can easily (or possibly is in the wrong hands) destroy all of humanity. Alpha Demon can allow Koira to shoot short energy bursts to those who aren't really a threat. When it comes to a major threat though, Koira is released and its astral form is a lot more powerful than the short bursts. Alpha does fear that if Koira is permanently released, untold destruction may occur and Alpha would be held responsible for it. Koira is a dragon that should be held responsibly.
