|“||The mother is mundane. The father is unholy. And this child possesses both a human soul and the blue flames.||”|
—Uriel, In Chapter 4, A Look Behind The Curtain
Rin Okumura is the son of Satan, half-demon, older brother of Yukio Okumura, and main protagonist of the Blue Exorcist fanfiction "Black Heaven".
Rin was born a few minutes before Yukio. The twins were both taken in by Shiro Fujimoto before he sealed away Rin's demonic powers inside the demon blade Kurikara.
Rin lived for fifteen years under the belief that he was a human being until he was attacked one day by the King of Rot, Astaroth. In the heat of the situation, Rin's blue flames awoke.
After being saved by Shiro, Rin's adoptive father revealed to Rin that he is not a human being, but rather a child of a demon born through a human mother. And the demon who fathered him was Satan himself.
Shiro quickly took Rin back to the church where he was attacked by another wave of demons. The demons were eventually fought off by a group of exorcists who worked with Shiro. However, Satan possessed Shiro's body and attempted to pull Rin into the Gehenna Gate. Before he could though, Shiro regained control of his body and killed himself to save Rin.
However, Rin was still being pulled into the Gehenna Gate. And so, Rin unsheathed the Kurikara sword, ending his existence as a human.
Later, Rin was approached by Mephisto Pheles, who said that Rin was far to dangerous to keep alive at this point. He gave Rin the option to either run away, or simply be killed on the spot. Instead, Rin declared that he would become an exorcist and kill Satan.
The rest of the canon in the story leads up to the Investigation Arc.
Chapter 1 Edit
Rin is in the process of recovering from a hangover when Yukio decides to pull a prank on him by turning on his music as loud as it will go.
Rin is about to respond to Yukio's actions when the entire building begins to shake.
Rin and Yukio then go to Mephisto's office where he explains that earthquake was the result of a demon, digging underneath the earth to enter True Cross Academy.

Chapter 3 Edit
Rin battles demons for a mission inside an abandoned school. He struggles against them, but then Gabriel enters and begins to kill his fair share of demons. Because Gabriel had not noticed Rin yet, Rin sheathed Kurikara, unsure if Gabriel was an exorcist.
When they returned to the cram school, Gabriel rejoined Uriel and the pair revealed that they would be attending the school as students. The pair then went to their own penthouse in the company of Yukio and Rin.
Rin and Gabriel then began a conversation in which Gabriel said he could tell Rin wasn't happy with working with his brother, but not to worry, because Gabriel had two siblings besides Uriel with whom he fought often.
Once Gabriel and Uriel went inside, Rin asked Yukio if he thought that their newest additions to the class knew he was the son of Satan. Yukio told Rin that they probably didn't, so it would be good practice in controlling his flames if Rin didn't use them while Gabriel and or Uriel was around.
