Riphal Edea

レファル・エディア, King of Gastark
He is the ruler of the Gastark Empire and a powerful warrior. He like Sion dislike the idea of waging war and tries to reduce casualities as much as possible as he believes there is no other way to prevent war than waging war itself. He eventually meets Kiefer in a battle against Stohl and shows a liking for her after she tried to protect two defenseless children and eventually invites her to his side to which she declines for the moment. He possesses the Rule Fragment known as Glouvil which is a large one bladed sword which upon sacrificing something grants him great destructive powers that can easily surpass those of a largescale spell. So far he has sacrificed his right leg sense of smell and his left eye for this. Source: Wikipedia
