The whole truth is that long ago he was someone in the Middle Ages, not just a random guy. By the way, he had a long time ago his portrait made by someone he didn't remember, that portrait is now safe but it's only a little piece, like 2/5 of the whole portrait. The other pieces were never found. But nobody recognized him because the only pieces of the portrait were just a part of the eye and hair mostly, but the hair was really similar... Well, let's continue, he was just a not really memorable little prince, because his brother was the prince, and Shuro was like nothing compared to him, and also well, people respected him too, and to have a little fun he just liked to fight with many swords, he had his own made, it was glorious and gorgeous. It also was made with gold and there were two roses representing two sides of a heart, also because roses are the love sign. This beauty was of course found and conserved well in a museum, it was not known whose sword that was, but it was Shuro's. Some other facts about him, he hasn't ever killed anybody, he just won more times than he lost, he lost just once and the last time. Those were the rules: he didn't kill but he was killed in case of loss. And that one last time he lost... lost the victory, lost the battle and... lost his life.
