Main Characters


 * Okumura Rin:
 * Okumura RinThe fifteen year-old protagonist of the story, Rin is the son of Satan born from a human woman and is the inheritor of Satan's powers. His powers were sealed at birth into the demon-slaying blade Kurikara, or Koumaken, by Mephisto Pheles, allowing him to live a normal human life for about 15 years. Rin became aware of his true identity after Kurikara could no longer seal the blue flames he inherited from Satan, setting a chain of events that led to the death of his guardian, Father and Exorcist Fujimoto Shiro, at the hands of Satan who attempted to drag Rin back to the demon realm. Exorcist Mephisto Pheles confronted Rin after Shiro's funeral with several exorcists, giving Rin the option to kill them all or die. Rin instead demanded to become an exorcist, an idea that amused Mephisto. Rin was then enrolled personally by Mephisto into the True Cross Academy Exorcist School, and since been pursuing his goal to become a Paladin and to defeat Satan. He is currently an Exwire and attempting to gain the title of Meister as a "Knight" (an exorcist who fights with a sword).
 * Rin can tap into the power he has inherited from Satan through the use of a demon-slaying katana, called Kurikara or Koumaken. The sheath acts as a portal to Gehenna (the demon world) which when drawn returns Rin to his demon form. While in his human form, Rin exhibits a number of physical traits that are signs of his demonic nature, such as sharper-looking teeth, slightly pointed ears, and a black, fur tufted tail (which he keeps hidden in his shirt). As a demon, Rin gains two blue flames that float above his head, long elf-like ears, and his eyes turn bright blue. In both forms Rin can control incredibly destructive bright blue flames, the trademark sign of anything related to Satan. However, when he draws Kurikara, the magnitude of the flames dramatically increases and often leads to Rin being "consumed" by his own flames and losing his mind. Rin also has a demon Familiar Cat Sith, Kuro, who was initially Father Fujimoto's.


 * Okumura Yukio:
 * Rin's younger twin brother. Though Satan's powers were expected to be split between them, due to the weakness of Yukio's body at birth, Yukio did not inherit any of Satan's powers. Yukio received a Mashou at birth from his brother, allowing him to become aware of demons since he can remember. Yukio secretly trained to become an Exorcist since age seven in order to protect Rin (through the help of (Fujimoto). While both Yukio and Rin are in their first year at True Cross Acadmey, Yukio is already an instructor at the Exorcist cram school who teaches Anti-Demon Pharmacology to Rin's class. It is often stated that Yukio is a genius, having already acquired the title "Meister" in both the Dragoon and Doctorclass, while ordinarily most people would aim for Meister in one class (both are still fully qualified exorcists). He is currently ranked as a Middle First Class exorcist. He has also recently shown that he can be a Tamer if the situation demands for it.


 * Suguro Ryuji:
 * Suguro Ryuji (nicknamed "Bon") is Rin's rival and the prodigy in the class. He was the child of the Cursed Temple which was destroyed by Satan 16 years ago. Bon takes everything seriously and is trying his hardest in order to become an Exorcist powerful enough so he could one day defeat Satan (a goal he claims Rin stole from him) and rebuild his Temple. Currently Bon is trying to acquire the title of Meister in both Aria (a person who recites holy texts to kill certain demons) and Dragoon (a person who fights with guns and other heavy artillery). He is currently an Exwire.


 * Moriyama Shiemi:
 * Shiemi is Rin's class mate and friend. Before she met Rin, Shiemi tended her grandmother's garden while her mother ran an Exorcists only shop inside True Cross Academy. During her encounter with Rin and Yukio, they were able to discover that Shiemi was having her life force leached out by a Demon. After Yukio exorcised the demon, Shiemi finally decided to become an Exorcist and started to attend class. It was later revealed that Shiemi had talent in becoming a Tamer, as she was able to summon a Greenman Spirit during class. It is apparently a rare talent to possess amongst the Exorcists, where there are only a few who can control demons and fight.
 * She is currently an Exwire.


 * Kirigakure Shura:
 * Kirigakure Shura is an Upper First Class Exorcist and Rin's mentor. She trained under the guidance of
 * Fujimoto Shiro to obtain the title "Meister" in Knight and can draw a demon sword from a symbol
 * above her chest when she states "Devour the Seven Princesses, slay the Serpent". Frequently chipper
 * and obnoxious, Shura is carefree about her job, known for drinking and oversleeping. She appears to
 * harbor a dark past, as she claimed Shiro "came and rescued" her. When she was introduced in the
 * manga, she broke up the fight between Amaimon and an exhausted Rin. Out of a grudge against Shiro
 * (who asked her to teach Rin how to use Koumaken) for "casting her aside" and orders to eliminate
 * anything she discovered related to Satan, Shura intended to "clean up her Master's messes".
 * However, Rin told her he would prove Shiro was right to let him live by becoming a paladin, leading
 * her to spare him and become his mentor. Shura also knows Yukio and nicknamed him "scaredy cat
 * four-eyes".
