Hiasen was left by his father, Ran, a wanted man who is trying to either revive or at least solve the mystery around his dead wife and Hiasen's mother, Senika. Hiasen grows up under the care of Ran's childhood friend, Kasin, until he joins Yeohadan to find a boy named Certa - something he promised Melly when she granted his wish to see his father when Hiasen was still a child. Hiasen's memorizing abilities and personality are exactly like his father's, but for some reason, his Innate Mana is not.
