The Kyo Kara Maoh! light novel, anime, and manga series features a cast of characters created by Tomo Takabayashi and Temari Matsumoto. The story mainly takes place on an alternate world, in a country called The Great Demon Kingdom (眞魔国, Shin Makoku). Yuri Shibuya, a Japanese high school student from Earth, travels between this other world and Earth by coming into contact with water. On Yuri's first visit to the other world he is informed he is the king of The Great Demon Kingdom.

The Demon Kingdom is split into 11 different sections. One section is ruled over directly by the king and the rest are each ruled over by one of the ten noble families of The Demon Kingdom (Christ, Voltaire, Grantz, Bielefelt, Karbelnikoff, Wincott, Spitzweg, Gyllenhaal, Rochefort, and Radford). "Von" comes before the surname of anyone who is a member of one of the noble families.

The Original King's era took place 4000 years before the present storyline.

Yuuri Shibuya (渋谷 有利, Shibuya Yūri) is the protagonist of the story. He was born in Boston, Massachusetts in the United States and grew up in Saitama, Japan. He is a high school student who enjoys baseball more than textbooks. The kanji Yuri's parents chose for his name Yūri (有利) means profitable, so people make fun of him by saying Shibuya Yūri, Harajuku Furi (渋谷有利原宿不利) (roughly translated meaning "if Shibuya is profitable then Harajuku is unprofitable"). His mother insists that he is named Yuri because he was born in July and it has nothing to do with money or the fact that his father is a banker. In the English dub, this became the pun "Yuri is short for urine." He later finds out that Conrad inspired his mother to use the name since he mentioned while she was in labor that, where he comes from, July is called Yūri.
