Arechia Obsidias

アレキア・オブシディアス, Sire
He is the King of the Obsidias region which makes him Junos father. He sent for a hero to kill the Demon Queen. The death of wife interfered in his way of thinking and ruling: once a kind and gentle person when her wife died because of the attack of a monster group he became a closeminded man who only wanted to wipe out all the monsters in the world.
