Race Werebeast Miko is the representative of the Werebeasts and rules over the Eastern Union. She lost her real name during the formation of the country when placing it as a wager. She looked down on Immanity at first, but after forming a truce with Sora and joining the Commonwealth of Elkia, she starts to have faith in the siblings who represent Immanity. She contains the rare Werebeast ability, Blood Break. Also, being a Blood Break capable individual, she ages very slowly. Sora had hypothesized Miko's age to be at least 58 years old, but her true age remains unknown. Despite her true age, Miko holds the appearance of a woman in her 20's.

Spoiler

Miko had to spend at least 50 years to unite the various Werebeast tribes into what is currently the Eastern Union, in which she lost her original name in a bet and gained her title as she contacted a certain Old Deus.
