Yukio Okumura

Although they are twins, Yukio is frequently noted to be the exact opposite of Rin, and Ryuji even states that he finds it hard to believe that they're related. Yukio is mostly seen as quiet and calm, but often has mood swings. He is usually seen happily smiling, but can easily get sidetracked due to Rin's personality clash, and becomes rather dark. He takes things seriously, but he knows a joke when he hears one. Although he and Rin get along for the most part, Yukio is usually quite aloof towards his brother, finding him annoying and often scolding him for not thinking things through. He also has a secret resentment towards Rin, not only because he's a demon and the son of Satan, but also because he feels Rin is the one responsible for their adoptive father's death. On few occasions, he is shown to have a very aggressive side, though he is very good at hiding it. If he is pushed too far, he can gain a fiercely angry personality. His angry side is so intense that it frightens Rin when it makes itself known. This may be as a result of his Demonic heritage even though he didn't acquire Satan's flames like Rin. The things that annoy him include, but are not limited to, people criticizing Shiro, Rin being "childish", Shura's teasing, being kept out of the loop, people asking him if he's alright and being called "weak". He doesn't like to partake in 'unseemly' actions. He is usually punctual and lectures Rin on how to behave. As the manga goes on, Yukio gets more and more frustrated with his twin because Rin keeps doing things that put him at risk. While Rin finally accepts what he is and the fact that he is Satan's son, Yukio just can't seem to accept Rin as a brother like he used to. Yukio is an extraordinary Exorcist, graduating at the True Cross Academy before becoming the next teacher in Demon Pharmaceuticals. Despite being one of the fraternal twins of Satan, Yukio did not inherit the blue flames.

He is shown to have demonic powers in him later in the anime, allowing Satan to possess him without any danger as a perfect vessel. He also is shown to have blue flames like Rin and his blood is that of a demon's. Although his demonic form has only been revealed in the anime, it has been revealed in the latest chapter of the manga that Yukio has, indeed, inherited some of Satan's demonic powers. Whether or not this results in demonic physical characteristics has yet to be shown. They say that his eyes are not his. We do not yet know what this means. As one of the youngest doctors in the True Cross Order, Yukio's medical abilities are top notch. He was able to treat Noriko Paku after being injured by a Naberius that Igor Neuhaus summoned, after being treated by Shiemi. In the manga, during the theft of the left eye of the Impure King, he cured a child named Satoru by inserting needles into the miasmatic boils on his body without rupturing the membranes of the cells, demonstrating his advanced knowledge of cellular biology- this is made further impressive as at the time, Yukio was also infected by the miasma while left reeling by the words of a possessed Saburota Todo. When he and his brother were young, he would treat Rin's injuries when ever he came home after getting into a fight. Yukio has brown hair and turquoise eyes. He also has three moles on his face and wears glasses (that's why Rin calls him Spotty-four eyes). In the first episode, Yukio wears a plain shirt with a beige cardigan. Later on in the episodes, Yukio has an exorcist coat that he wears over a white dress shirt and black dress pants. Over his coat he has a leather pallet of bullets and his guns. He has black leather shoes. and black socks. In his left breast pocket of the coat, He has a Knights Pendant. Colors of blue, red, and silver. He has two Springfield M1911A1 Champion pistols, both black with a glossy wood side cover on handle, and the True Cross insignia engraved into the slide. he is 5’11.

He is popular with girls, though he finds it difficult to reject them. he tends to just run away, but some of the girls that like him are a little psycho. He averages 4 hours of sleep each night. His known pastimes are: formulating plans and reading Jump Square every month. His favourite manga genres are: comedy, horror, suspense. He is embarrassed and extremely bothered by how many moles he has. He gets irritated with Shura ever since they were young because he always gets defeated by her (and she’s always drunk). He is ambidextrous meaning he is dexterous with both hands and has used this to his advantage, combining it with multi-tasking. This ability shines through when he is in battle. He has a small crush on Shiemi Moriyama, so does rin. Shiemi has straight, shoulder length platinum-blond hair (though her hair is simply blond in the anime), green eyes, and fair skin. Her hair occasionally curls at the ends, and she is usually seen with a clip or headband in it. In the manga, her hair is much lighter than the anime, appearing almost white at times. Shiemi also has noticeably large breasts despite her figure, which shocked all of the guys when they first saw her in the school uniform as the kimonos she usually wore concealed her figure. she is very kind and optimistic and treats everyone she meets with respect, even if they don't always return the favour. She also starts rather clumsy, frequently tripping, though she overcomes this after swapping her kimono for a school uniform. Shiemi is also very naive; most of her life was spent within the premises of her home, therefore she is rather clueless when it comes to typical adolescent experiences and grew up without any real friends. However, she is incredibly loyal, patient and hardworking; she would do anything for her friends, even if it would make others feel uneasy.
