Saralegui

The young king of Small Cimaron who asks Yuri to call him Sara. He is extremely beautiful and at first glance seems soft-spoken and kind-hearted. He's already at adult age but still uses 'boku' which is usually used by young males when referring to themselves. He can't remember much about his parents. He has the power of hypnosis, which he tried to use on Yuri, but with no effect. His first appearance was in the anime was during the third season where he meets a disguised Yuri at a ball. The two become friends despite misgivings Yuris friends have concerning the human king. During Yuri's visit to Small Cimaron, in what appears to be a selfless and heroic act, Sara takes an arrow in Yuri's place. Yuri is moved and even Wolfram, who had previously shown a strong dislike towards Sara, is touched by the young king's attempt to protect his fiancé. Murata and Conrad still remain suspicious of Saralegui's true motives. (Source: Wikipedia)
