The story's protagonist. Born and raised in Saitama prefecture. A high school student who prefers baseball to textbooks. Conrad 'named' him when he told Yuri's mother that, in his place of origin, Yuri means July. Early in the series, bullies mock Yuri's name by calling him "Shibuya Yūri, Harajuku Fūri" (advantage Shibuya, disadvantage Harajuku)—a reference to popular districts of Tokyo. In the English dub, this becomes a pun on "Yuri is short for urine."
Upon arriving in Shin Makoku, Yuri is declared the 27th Maoh of the Mazoku ("Demon Race"). Yuri easily gets caught up in his emotions to the point of losing control. He is somewhat quick to anger, and once on a rampage, he cannot stop himself. A former music teacher dubbed his rants "the Turkish march." When he is angry, sad, or experiencing strong emotions, his natural powers emerge. Yuri uses expressions from historical dramas in this state, likely because he loves them. This condition is sometimes called "Maou mode" (「上様モード」 in Japanese, "emperor mode"). In the anime, this form is recognizable mainly by longer hair and demon eyes. He can summon powerful magic (majutsu), even in human territories—a notable feat, as most Mazoku cannot perform magic outside their country. Even more remarkably, he can use majutsu in souseki-filled areas, such as the souseki mines, where other mazoku struggle to stand or breathe. Yuri's magic manifests in various shapes—usually one or more great water dragons, or some messy magical "creature" made from mud, food morsels, etc. After spending time in this form, Yuri becomes worn out and, in some cases, passes out and does not remember what happened afterwards. Later, Yuri learns to control his power and uses it to close the first of the Forbidden Boxes. At the beginning of season 1, he often fainted after using Maryokou (especially in Human land) due to exhaustion. But later, he was able to maintain his consciousness after returning to his "former self."
Yuri has many allies and friends. His closest allies are Wolfram, Conrad, Günter, Gwendal, Murata, and Josak. They help Yuri throughout the series. At his first encounter with Wolfram von Bielefeld, he ends up engaged to him due to a mishap: Wolfram, angry that Yuri has been chosen as the Maoh, makes the mistake of insulting Yuri's mother—which earns him a slap. Slapping another noble on his or her left cheek is the way in which Mazoku propose marriage (some consider the slap unmanly, but Yuri explains in the light novel that he only slapped Wolfram because he has a beautiful face; otherwise, he would have punched him). Incensed by this insult, Wolfram challenges Yuri to a duel, which is also mistakenly accepted because of Yuri's unfamiliarity with Mazoku custom (he picked up the knife that fell off the table).

Spoiler

Throughout the series, his main goal is to create a world in which Mazoku and humans can live together in peace, something that progresses slowly but surely as the series goes on.
