The Two Forms of Yuri: Maoh and teenager

Voiced by: Takahiro Sakurai (Japanese); Yuri Lowenthal (English)

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.[3] 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.

When Yuuri first arrives in The Demon Kingdom, he is told that he is the 27th King of the Demons.[4][5] Throughout the series, he strives to create a world in which demons and humans can live together in peace, something that progresses slowly but surely as the series goes on.

Yuri easily gets caught up in his emotions, to the point he loses control of himself. He is quick to anger, and once he's angry he cannot stop himself. When he is angry or sad or feels a strong emotion his powers emerge. Yuri is a huge fan of Japanese historical dramas and so when he is in this mode he uses expressions from those dramas. Fans call this condition "Maou mode" (or emperor mode (お上様モード, uesama mo-do) in Japanese). In the novel there is no note of his appearance changing, while in the manga and anime his eyes become slitted and his hair may grow longer.[6]

At the beginning of the series, Yuri could only access his magic when an emotional event triggered it. He would usually pass out after using his powers, only to wake up later and not remember what happened. Later on in the series, Yuri learns to control his power. He can summon powerful magic, even in the human territories, while most demons can only perform limited magic outside of the country.[7] He is unaffected in houseki-filled areas and is able to wield magic in those spaces, even while full-blooded demons have difficulty standing and even breathing. Yuri has a contract with water and uses his magic to create various monster-like shapes, most notably using it to create water dragons. He has also been known to make other messy magical "creatures" from mud, food scraps etc., much to the horror of the other demons and every one who sees them.[6]

Yuri ends up engaged to Wolfram von Bielefelt when he first meets him through a mishap. Wolfram, angry at the idea that Yuri, a half blood demon, is supposedly the king, insults Yuri's mother for being human which earns him a slap. According to noble demon culture slapping another noble on his or her left cheek is the way in which noble demons propose marriage.[6] Wolfram, considering this an insult, challenges Yuri to a duel (by throwing his knife on the floor) which Yuri also mistakenly accepts because of his unfamiliarity with a demon custom of accepting duels by picking up fallen knives.

It is revealed fairly early in the series that Yuri is in fact the reincarnation of Susanna Julia von Wincot, who was a blind healer that died during the war against humans 20 years ago.[8][9] Conrad gives Yuri a tear-shaped pendant that used to belong to her. When Yuri first arrives in the Demon Kingdom, Adalbert von Grantz, who was originally Susanna Julia's fiancé before she died, brought out his stored language memory in his soul so he could understand the spoken demon language. While this event helps Yuri understand spoken demon language, he is still unable to read it; later on, he realizes he can "read" the demon language if he runs his fingers over the print, owing to the fact that Susanna Julia was blind and read this way. There is a time in the novels where Julia's influence takes over Yuuri's body and he temporarily loses his eyesight. Yuri's blood is also one of the keys of the forbidden boxes. He inherited this from Julia. In the anime it is said that Yuri inherited the key to the box through Christel Wincott because all of the Demons on Earth are descended from Christel after he traveled with one of the forbidden boxes to Earth 4,000 years ago. This is never mentioned in the original novels.

In the anime, Yuri is said to be the greatest Demon King after defeating The Originator and freeing The Original King from the dark power. Because of that, Yuri is able to travel between worlds even without the help of The Original King.[10]

Mullem Desoive Eligh Morgif (モルギフ, Morugifu)

Voiced by: Takahiro Sakurai (voice altered)

Morgif is the demon sword which can only be wielded by the Demon King. It is a talking sword with the personality of a cheerful, lecherous old man. Murata, who knew the sword when he was the Great Sage, mentions that Morgif had changed a lot over the years. According to Murata, Morgif used to have "a young and handsome face" and a "soothing counter-tenor voice".[11] Morgif originally had a jewel on its 'forehead' that served as the source of his power, but it fell out when Cheri dropped the sword while handling it. Yuri then gave the jewel to Josak and told him to do whatever he wanted with it.[12]

In the anime, the jewel is eventually returned to Morgif when Yuri has to fight a powerful Holy Sword.[13] While the jewel is the source of Morgif's true power, Morgif is still a formidable weapon without it. The extent of his powers without that source are a mystery, and his powers with it are said to be limitless. It is later explained that Erhard Wincott, the ancestor of Susannah Julia von Wincott, was an inventor who tested Morgif and researched its history.[14] Morgif was created from powerful lava streaming from a particular volcano on Van da Via Island. If Morgif is thrown into the lava again, it would assume its original form, a heavily decorated black sword, which Yuri uses to defeat The Originator.[15]

Sir Conrad/Conrart Weller (コンラッド/ウェラー卿コンラート, Konraddo / Werā kyō Konrāto) is the second son of the previous Demon Queen, Cecilie von Spitzweig. His given name is "Conrart" but Yuri calls him "Conrad" since it is closer to English and easier to pronounce. Conrad is only half demon and because of this he is unable to wield demon magic. His father was a human named Dunheely Weller who was famous for his swordsmanship. As Conrad's father was not a demon noble, he does not have "von" in his name.[1] Conrad is the captain of the Demon Kingdom's army and is Yuri's personal bodyguard. When Yuri first arrives in the Demon Kingdom, it is Conrad who finds him and brings him to the castle.

Conrad fought on the front lines for the demons during the war against the humans in order to prove his loyalty to the Demon Kingdom. He and Yozak Gurrier were in an all half blood platoon named the Lütenburg platoon and are famous for being the only two survivors from the Battle of Arnold. Conrad thus gets the name "Lion of Lütenburg" from this battle due to his heroics and bravery. In the anime, this battle is where Conrad receives his characteristic scar above his right eye.

Conrad and Susannah Julia had a close relationship prior to her death. 17 years before the present time, after the war had ended, Conrad was put in charge of Susannah Julia's soul at her request since it was going to be the new Demon King. He then took her soul to Earth so that it could be reborn in the body of Yuri.[16]

At one point, Conrad loses his arm in battle but later appears with a new arm. It is explained in the novels that this "new" arm originally belonged to his ancestor Robert Belal, who was transported to Earth in 1798. When Conrad's arm was cut off, The Original King took the arm and gave it back to Conrad. This arm is the key to the forbidden box named "The End of the Wind".

His ancestor, Lawrence Weller, fought alongside The Original King.[17]

Because Conrad stayed on Earth for a time when Yuri was being born, he is knowledgeable of certain Earth tendencies and the culture of Japan. Due to this, he also has an interest in baseball and frequently plays catch with Yuri. He is also known for his horrible puns.

Lord Wolfram von Bielefeld (フォンビーレフェルト卿ヴォルフラム, Fon Bīreferuto kyō Vorufuramu) is the youngest son of the former Demon Queen, Cecilie von Spitzweg. He is the only one of the previous queen's three sons who inherited her emerald green eyes and blonde hair and he bears a striking resemblance to her. It's also mentioned that he closely resembles The Original King. Celi says he inherited his selfishness from his father, but he can be very manly and reliable. His handsome appearance is so influential, that dying people in the hospital had miraculous recoveries after laying eyes on him. Wolfram possesses fire magic (a trait from his mother's side of the family), as well as being adept with a sword. He is one of the leading practitioners of fire magic in Shin Makoku. He is the half-brother of Conrad and Gwendal. The original author of this story, Tomo Takabayashi has said that Wolfram is her favorite character.

He finds himself engaged to Yuri after a misunderstanding. When he first becomes engaged to Yuri he is extremely upset, but the idea quickly grows on him. He takes the engagement much more seriously than Yuri does. He follows Yuri practically everywhere so he can keep an eye on him and even sneaks into Yuri's bedroom at night. He gets extremely jealous when Yuri talks to a girl or good-looking guy and often accuses him of being unfaithful which is sometimes used as comic relief.

He initially dislikes humans, even Conrad's father. Because of his demon pride, he does not like to admit that Conrad is his brother, even though he cares for Conrad. In the novels, it is hinted that this hatred towards humans stems from his late father's prejudice against humans. His attitude towards humans improves throughout the series, progressing to the point that he adopts the human girl Greta as his daughter, starts acknowledging Yuri's parents as his future "in-laws" and also runs into a raging fire to save a human child.

A major weakness is that he gets sea-sick. Yuri also says that Wolfram cannot paint well, even though he insists on painting. For example, he tries to paint Yuri, although it turns out unintentionally impressionistic.[18] However, in the novels and manga it is said he could paint very well when he was young when he painted realism but now he decided to change his style to cubism.

Near the end of the second season, there is a time when Wolfram is possessed by The Original King, who in turn was possessed by The Originator. The key he possesses, his heart, is ripped out by The Original King so he can open one of the four forbidden boxes, "Hellfire in Frozen Land". Because of this, Wolfram temporarily dies, and Anissina puts him in a special box to keep him alive. He is revived when The Original King returns the keys to their owners.

His ancestor, Rufus Bielefeld, fought alongside The Original King.[17]

In a story original to the anime at the beginning of season three, Wolfram is chosen by the Ten Noble Families of The Demon Kingdom to become the next Demon King, due to the belief that Yuri would not be able to return to The Demon Kingdom at the time. When Yuri does return Wolfram's uncle, Waltrana, places pressure on Wolfram to obtain the throne. Because of this, Wolfram dissolves the engagement with Yuri and travels back to his homeland, in hopes that he would not be used to sabotage Yuri.[19] When Yuri hears of Wolfram's predicament, he and his retainers travel to the Bielefeld lands in the hopes of persuading Wolfram to return to Covenant Castle, only to be forced into a formal duel by Wolfram himself. In the process of aiming a strong attack at Wolfram, Yuri realizes that Wolfram seems to be preparing himself for his last moments and gives his final words to Yuri: "Yuri. Be a good king." Realizing that Wolfram had planned the whole thing from the beginning so Yuri could remain the Demon King, Yuri absorbed the attack onto himself at the last moment, sparing Wolfram from damage. The Ten Noble Families then changed their decision to keep Yuri as their king and Waltrana steps down from forcing Wolfram onto the throne. After a reconciliation between the two, Wolfram happily decides to annul their disengagement to a comically shocked Yuri and proceeds to return to his normal attitude towards their engagement.[20]

Lord Gwendal von Voltaire (フォンヴォルテール卿グウェンダル, Fon Vorutēru kyō Guwendaru) is the eldest son of Cecilie. He is the current lord of Voltaire. He is a skilled tactician and is capable of using earth magic and can cast barriers.[6] Gwendal is a tough guy except when it comes to his childhood friend, Anissina, and his brothers. He is afraid of Anissina and often hides from her so he can prevent being used in one of her crazy experiments. He is even seen sweating in panic at the thought of her.[21][22] While he does not outwardly show much affection towards his brothers, he shows in times of great stress that he does care. When not otherwise busy, Gwendal indulges in his hobby of knitting but often his creatures look nothing like what they're supposed to (for example a bear got mistaken for a black pig or a cat that looks like a raccoon). He is adamant that knitting helps him sharpen his concentration but actually it's a stress reliever for him since childhood. He is also quite fond of cute animals or cute objects such as the dolphin key chain (Bandou-kun) Yuri received at the dolphin show and later gave to him.[23] His childhood best friend is Anissina von Karbelnikoff, an inventor who often tests out her inventions on him, much to his displeasure. Anissina is also the one who taught Gwendal how to knit.[22] Gwendal's left eye is a key to one of the four Forbidden Boxes, the "End of the Earth".

When he and Yuri were alone in the desert following a sand trap that sucked in Wolfram and Conrad, Gwendal showed certain care towards Yuri and smiled. Yuri later commented to Conrad that the siblings have similar smiles, even though Gwendal's is covered up by his "scary face".[24] He is the commander of the demon army and often comes with reinforcements when Yuri finds himself in big trouble. He is also the one who does the paperwork and essentially runs the kingdom for Yuri.[25] Often enough, when Yuri leaves the castle, Gunter is seen barging into Gwendal's office, demanding where Yuri is. Gwendal would usually look tired and suggest an idea which sounds appealing to Gunter, for example locking Yuri up in a room where no one will interfere.[26]

When he was younger, Gwendal despised humans, a habit called the Demon Pride by Dunheely Weller. On Dunheely's last journey to a nameless village, he told Gwendal to enjoy the ride before their last duel. Upon arriving in the village, Gwendal is shocked that the village is not recognized by The Demon Kingdom, and leads the attack on the bandits which targeted the village. In this duel, Gwendal sees Dunheely for who he really was, an old man, not the agile man he knew when he was younger. Dunheely later dies of old age, and Gwendal buries him near the tree where Dunheely told Gwendal what he was looking for. Years later while on a picnic with his family and Yuri, Gwendal admits that Dunheely was a larger existence than anyone else within him, because he hated that man.[27]

Gwendal has no interest in love affairs, and even points out that issues coming from love affairs are beyond his abilities to influence.[28] He does occasionally show care towards Greta, often being in charge of her while Yuri and Wolfram are in one of their adventures. Gwendal knows how to bake, as he does so for Greta when Günter, who would usually bake cookies for Greta, leaves the castle for a short journey. Greta comments that Gwendal's cookies look cute while Yuri comments Gwendal is good at baking as Gwendal's cookies are made into animal shapes, similar to the ones he knits.[29]

His ancestor, Siegbert Voltaire, fought alongside The Original King.[17]

Lord Günter von Christ (フォンクライスト卿ギュンター, Fon Kuraisuto kyō Gyuntā) is Yuri's adviser and teacher. Günter is a skilled swordsman and magician. He is a very whimsical person and poetic in his thoughts. He is Anissina's number 2 test subject. He has an extremely strong attachment to Yuri and tends to pine for Yuri when has been gone from The Demon Kingdom. 20 years ago he was an instructor at a military academy.

When Gunter was shot with a poisoned arrow containing the Wincott poison, his soul was temporarily housed in an Okiku Doll that flies, shoots lasers from its eyes and has hair that grows naturally. During this time he referred to his body as Snow Gunter and it could be controlled by or released from the effects of the Wincott Poison by anyone of the direct line of the von Wincotts like Julia's father and nephew.

When Günter accidentally travels to Earth, he becomes a model in New York City for a brief period of time so that he can earn money to find Yuri.[30] He is very popular among females and males because of his good looks.

In the light novels, he is discovered to be from a lineage called the People of Lake Shore. He describes them as such: "There are many among them who are born with strong magical powers, and they act as teachers and guards here in the capital." They are identified due to their purple-colored hair or eyes.

Gunter is an odd mixture of manly fighting skills and stereotypical feminine personality, and as such is a comic presence in most episodes.

Günter's only family seems to be his adopted daughter Gisela.[31]

Dunheely Weller

Voiced by: Kenyuu Horiuchi (Japanese); Kirk Thornton (English)

Dunheely Weller was Cecelie's second husband and Conrad's father. At his time of death he was 89 years old. On his left arm he has a tattoo marking him as the last descendant of the exiled three continent royal family(大陸三王家). Despite resistance, he married Cecelie and had a son – Conrart. Celi herself admitted that their wedding was approved by The Original King. In his youth, Dunheely took Conrad on trips with him to the human lands. Dunheely championed the rights of half-human, half-demon and spent decades in making their lives better. It is known later on that an ancestor of the Weller family was entrusted with the key (left arm) for one of the Forbidden boxes.[41] Dunheely Weller kept the family secret and became a wandering swordsman of amazing prowess.

Voiced by: Shin-ichiro Miki

His soul watches over the lands of The Demon Kingdom, and priestess such as Ulrike and Ondine can communicate with him in a limited fashion, one they call "hearing His Majesty's voice". Murata also appears to be able to communicate with him, and is often seen scolding him for meddling in The Demon Kingdom's affairs.

4000 years ago, The Original King sealed The Originator into four boxes, which became known as the "Four Forbidden Boxes". However, while part of The Originator was sealed in the boxes, a small part of The Originator infected The Original King to the extent where his right arm seemed slightly decayed.[42] The Original King knew that The Originator would eventually take over his mind and body completely, so The Original King came up with a plan along with his Great Sage to completely eradicate The Originator in the future. This involved sealing The Originator with a pure soul, and then destroying it.[10] This soul turned out to be The Original King, but Yuri manages to eradicate The Originator without harming The Original King, earning Yuri the title of the greatest Demon King. The Original King commented that he was glad he chose Yuri as the Demon King.[10]

The Original King appears to be well alive in the OVAs, having seem to regain a physical body unlike his soul form at the end of Season 2.[10]

The Original King told Yuri that with The Originator destroyed, his aim of choosing Yuri as the Demon King has been reached, and Yuri no longer needed to be the Demon King. Since Yuri can achieve his goal very well, The Original King said that he will not hold back the decision of choosing Yuri as the Demon King and blesses him. The Original King has stated he will reduce anyone who opposes Yuri as the Demon King to ash.[19]

Voiced by: Katsuyuki Konishi (Japanese); D.C. Douglas (1st), Patrick Seitz (2nd) (English)
Shori Shibuya (渋谷勝利, Shibuya Shōri) is Yuri's older brother who goes to Hitotsubashi University. He likes to play dating simulators and is very protective of Yuri.[45] He is Bob's successor to be the Demon King of Earth.[46] When he was younger, he met Bob who rescued Yuri and him from bullies. While initially despising his parents for having an argument, he also resented the fact that Yuri will have to go to The Demon Kingdom eventually. Bob explained to him that that would happen in the future, and so Shori was contented being with Yuri for the time being.[46] Shori communicates regularly with Bob, who he complains emphasizes his age more than anything else. His short term ambition is to become the governor of Tokyo.

Often carrying a cold attitude, he did not welcome having Wolfram and the others in his house. He seems especially distasteful to Conrad, and makes a point of demanding that Conrad returns his clothes to him properly cleaned (since the two of them are about the same build and size, Jennifer usually lends Shori's clothing to Conrad).[30] Later, he and Conrad form an understanding based on their mutual desire to protect Yuri.

In the anime, Once Shori ends up in The Demon Kingdom, he becomes suspicious of The Original King, Murata, and the four forbidden boxes.[47] Shori eventually goes to The Demon Kingdom where he learns to use the powerful magic he possesses.[47] Wolfram gave Shori a pact to the elements, somewhat like how Odine gave a pact to Yuri to gain control of his magic.[48] Shori's magic is like of Yuri's, the control of water, but initially Shori's magic takes the form of a giant hand.[49] He is, however, seen to be able to shape his magic into water dragons after training with Ulrike, who comments that Shori is extraordinary because he learned to control his magic slightly in a short span of time.[14]

Dr. Rodriguez is a pediatrician who loves Japanese anime and often travels to Akihabara to buy Gundam models. It seems he was close Christine and so he took care of her spirit after she died which was then born as Ken Murata. He became Murata's pediatrician when Ken was younger and began to remember his previous lives. Later on he is seen working for the Demon King of Earth.

The Originator

The Originator according to Murata, is a formless being which is composed of the negative emotions of humanity.[10] Due to its state, it can easily enter the hearts of people who have negative feelings. When the people of The Demon Kingdom began to rebel against The Original King, The Originator further infected The Original King due to his frustration with his people.

The Great Sage and The Original King came up with a plan to completely eradicate The Originator. This involved sealing The Originator with a pure soul, and then destroying it.[10] This soul turned out to be The Original King, whose soul was sealed with The Originator into the Four Forbidden Boxes. The pair decided the Great Sage would be reincarnated so he could find and assist the person who would finally be able to destroy The Originator completely. The Originator (using The Original King's memories) tells Yuri that The Original King and the Great Sage intended that person to be Julia von Wincott, but she was, ironically, too pure for The Originator to possess.[50] Yuri became the last, best hope for victory. With the help of Morgif in its original form, Yuri managed to destroy The Originator without harming The Original King.[10] Yuri inherits The Original King's power, which earns him the title of the greatest Demon King.

The Originator's shadow was a tall gigantic masked figure which possessed Belar for a short time. When Yuri breaks the control spell on Josak, Adalbert and Keenan, the shadow of The Originator disappears, but not before it possessed Wolfram.[51] When The Originator possessed Wolfram, Wolfram was forced to disrupt the sealing ceremony, and stay still while the key, Wolfram's heart, was ripped out by the form of The Original King.[34]
