Yuuri is a young boy with black hair and eyes, to which the Mazoku people call as a «soukoku» (double black). He wears black clothes that look very much like a typical Japanese high school uniform, and brown shoes. When attending formal events, he sometimes wears a violet mantle around his shoulders with golden shoulder pads.
In the anime, when entering his Maou mode, Yuuri's hair grows longer until it reaches shoulder length and his eyes becomes slit. In the manga, his hair doesn't grow, but there is that visible change in his eyes. In the novels, there is no note about a change of appearance whenever he enters his Maou mode.
Yuuri is a cheerful, baseball-loving, idealistic, naive, emotional, and likable Demon King who dislikes war and conflict. Everyone who disapproved of him first somehow became drawn to him most likely due to his warm personality and determination to bring change to the world. He most often believed that anything can be solved if people took the time to understand each other, and always attempted to prevent any battle or conflict to happen while he's around. He always goes around doing everything in his power to get things done, even if it's to risk his own life. Miraculously, he always gets out of it alive.
Yuuri easily gets caught up in his emotions, to the point he loses control of himself. He’s quick to anger and once angry he can not stop himself and keeps ranting till he exhausts himself. He had a music teacher in elementary school who called his outburst a "Turkish March". Before he learned to use his magic, his powers only really emerged when he had a strong emotion so they came out when he had one of these rants. Since Yuuri is a huge fan of Japanese historical dramas, he tends to uses expressions from historical dramas. Fans call this condition Maou mode (or emperor mode (お上様モード uesama mo-do ) in Japanese).
Yuuri was born in Boston, Massachusetts, but grew up in Saitama, Japan. The kanji Yuuri's parents chose for his name is 有利, which means "advantage", a very strange kanji to choose for a name so many people make fun of his name while he was growing up by saying Shibuya Yuuri, Harajuku Furi (roughly translated meaning "if Shibuya is at an advantage, then Harajuku at a disadvantage") and making jokes about it having to do with his father being a banker.
His mother insists that she named him Yuuri because he was born in July and that it had nothing to do with money or the fact that his father is a banker. While the choice of kanji remains a mystery, Yuuri later finds out that it was Conrad who inspired his mother to use the name since he ran into her when she was in labor and mentioned that where he comes from, July is called Yuuri.
Yuuri was just a normal Japanese high school student who loved baseball until he was taken to another world and is told that he is the 27th Maou. At the beginning of the series this was the only way Yuuri could access his magic and he would became worn out and in some cases passes out and did not remember what happened afterwards. But later in the series, Yuuri learns to control his power. He can summon powerful magic, even in the human territories, while most Mazoku can only perform limited magic outside of the country.
This is because the particles that obey their maryoku are lower in the areas where humans who worship god live. He is unaffected in houseki filled areas such as the houseki mines and can even still use his magic while full blooded Mazoku have difficulty standing and even breathing. Yuuri has a contract with water and uses his magic to create various monster like shapes, most notably he uses it to create water dragons, but he has made many other messy magical "creatures" made from mud, food scraps etc. much to the horror of the other Mazoku and every one who sees them.
Yuuri ends up engaged to Wolfram von Bielefelt when he first meets him through a mishap. Wolfram, angry at the idea that Yuuri, a half blood, is supposedly the king, insults Yuuri's mother for being human which earns him a slap. According to noble Mazoku culture slapping another noble on his or her left cheek is the way in which noble Mazoku propose marriage. Wolfram, considering this insult, challenges Yuuri to a duel (by throwing his knife on the floor) which Yuuri also mistakenly accepts because of his unfamiliarity with a Mazoku custom of when someone throws a knife on the ground it is a challenge to a duel and picking up said knife is accepting the duel.
It is revealed fairly early in the series that Yuuri is in fact the reincarnation of Suzanna Julia von Wincott who was a blind healer that died during the war against humans 20 years before the present story line. Conrad gives Yuuri a pendant that used to belonged to her. When Yuuri first arrived in the other world Adalbert brought out his stored language memory in his soul so he can understand the spoken Mazoku language but because Suzanna Julia was blind he was unable to read the language. Although, he can read raised letters with a finger. There is a time in the novels where he panics Julia's influence takes over and he temporarily loses his eyesight.
Differences in the anime
The anime is greatly changed from the original novels. In the anime they gathered all 4 of the forbidden boxes and found out that Shinou was possessed by Soushu and so Yuuri has to defeat him in order to defeat Soushu. This is not possible in the novels because Henri Régent (one of Murata's past lives on Earth) took the forbidden box that was on Earth (Mirror's Depth) to hide it somewhere safe where no one would find it but the boat he was on ended up being attacked and so he and the box sunk to the bottom of the Pacific Ocean.
In order to explain how Yuuri is still able to travel between worlds in the anime after Shinou is defeated they say he is the most powerful Maou after defeating Soushu and freeing Shinou from the dark power so he has the power to travel between worlds.
