At an earlier age, Hugh acted as the primary retainer under Rebecca's father, who was the king of Zymot at the time. One day, however, Hugh had attempted to kill him, which was when the king placed his half key Spirit into Rebecca's forehead. Due to this fact, Hugh continuously captured Rebecca and later convinced Rebecca's father, whom he had let live, that he would marry Rebecca and become the new king of Zymot. This is only a trick, however, in order to make Rebecca's father release the shard within her head. After Hugh receives the shard, he kills Rebecca's father and casts her away, free to do whatever she wishes. After this event, Hugh became the new King of Zymot, and lusts to obtain every key Spirit he can get his hands on; this is Hugh's true ambition.
