After a hunt gone wrong, the Winchesters find another pair of brothers stranded on the side of the highway. Seems pretty simple, but there’s just something...off about the kid.

Apparently, in this world, having pointed ears makes you an Elf. In other news, Rin has fallen into a medieval world and has no idea what is going on. Rated T for excessive use of line breaks.

Renzō has been dropping subtle hints to Rin about his feelings for him, but Rin has misunderstood every one of them. Renzō knows things would be easier if he cleared some things out from the start, but hasn't been able to bring himself to do it. Things take a different turn when he invites Rin to a friendly date. RenRin.

How do you hide being the son of Satan? How do you deal with a body that is unknown to you? How can a demon possibly become an exorcist without having his true identity discovered? Do tails have a life of their own? Are there classes you have to avoid? How far can you go without others getting suspicious? /Rin learning what not to do as a half-demon.

What if blue flames weren't the only thing Rin inherited from Satan? The fiddle is the devil's instrument, so what would happen if Rin got his hands on one? He knew taking high school courses had been a bad idea from the start. Post Kyoto Arc. Two-shot.

The secret is out that Rin Okumura is the son of Satan. Now he's been sent away to Yokai Academy for everyone's safety including his. Abandoned by his friends and the only family he has left, will he be able to make new friends and have a life in a school full of monsters or will this be another Blue Night waiting to happen? Will follow elements of mostly the anime and maybe Manga.

When Rin develops magic at a young age, he is sent from hell to go to hogwarts and eventual enslave humanity for satan. Little does he know, Rin had a plan to kill his father as soon as he can. Question is, will the chosen one want to help?

A few things that make Rin himself and the thoughts and stories that come along with it.

He's well-known for being the spawn of the king of Gehenna. But contrary to popular belief, Rin is the furthest thing from a demon. A series of Rin-centric drabbles in which he proves that he, as the son of Satan, is full of surprises. Gen, rated for swearing. Genres vary.

"When you called and said you needed me in Assiah, I didn't think this was what you had in mind." "Trust me, Amaimon, it very much wasn't, I had no idea he was even capable of these heats." Rin's issues happen to include more than being in a tug of war between the two halves of himself. Now, they include demonic hormones too.

AU Seven year old Yukio swore to protect his younger brother Rin when he was born. Eight years pass and he's kept that promise ever since. He works to keep Rin safe from demons as an exorcist but that turns into a challenge when the seal on the sword that the young half-demon's powers were sealed in weakens. (Full summary inside)

Rin experiments with some unknown powers along side Mephisto and Amaimon. This is a one-shot that's not connected to my other stories.

What would happen if Rin is taken as a baby by Mephisto? What would happen if he was made a full demon, and Yukio a full human? What would happen if Rin was raised in Gehenna? This and more in Blue Flames & Pink Smoke. Adopted from WhitB. UNDERGOING REWRITES

With the awakening of his demon blood, Rin has had many changes and he has to learn how to adjust to the sudden enhancements, abilities, extra limbs, and anything else he gained from his demon blood. This is a collection on how he adjusts to these things.

Movie AU. In which, Rin didn't make it off the runaway Phantom Train in time…and ended up in Gehenna. The Grigori was not amused. Satan on the other hand- "Aww, come on, smile for Daddy!" "Urusei, baka-Ossan!" *You do not have to have seen the Movie to read this.* Language and Violence. Still GEN folks.

Arthur Auguste Angel did not want to admit that the antichrist was anything more than, well, the antichrist. It did not matter how pleading he could make his kicked puppy eyes go, Rin Okumura was the Son of Satan. This mindset would be ingrained in him until the day he died… or so he thought. [One-Shot]

Seven-year-old Rin only wanted to escape. In the process of doing so, he finds out he has the ability to summon blue fire. But when he is approached by a stranger claiming to want to take him home, what does he do?

Various (mostly comedic) ways of exposing Rin's demonic secret. Post a review containing an idea for a reveal and it may get featured!

"I'm not crying…" the boy stuck his nose in the air and wiped his cheeks. Amaimon grinned."What's your name then, and why are you NOT crying?" Amaimon asked and the boy grinned up at him a teensy bit. "My name is Rin. My…my daddy left me here while we were playing, 'cause he had to do something. What's your name?" Amaimon stuck out a hand to help Rin stand, "My name is Amaimon."

In a world where Rin is the younger brother and born with the ability to see demons too feels abandoned when Shiro begins to teach Yukio and ignoring him unintentionally. He needed someone there for him too and luckily or unluckily Mephisto seems takes an interest in him and take him under his wing. But is it all or is it another of his plans?(Genius,not violent,polite.Rin)

"Ah, I guess you could say I'm your older brother. Nice to meet you. From now on, please call me 'Amai-nii.'" Rin meets his first demon when he is seven years old.

The probability of people being diagnosed with the Hereditary Evil Raiser Syndrome nowadays, in the year of 2017, was nearly impossible! Note: nearly. The HER Syndrome was supposed to have died out at EC 611, when Irina Clockworker, Eve Moonlit, and Levia's souls merged to form the entity known as MA! But why was Rin showing HERs' symptoms? Has some refs to the Evillous Chronicles

In which Rin struggles to hide another secret on his journey to become an Exorcist, Satan is having too much fun being stuck in the half-demon's head and the two (unknowingly) drive Yukio insane with their antics. "No Rin... I am your father." "You did not just go there!" "Ah, but I did." [Crack-fic!]

Yukio can't decide what's worse: the fact that he constantly has to act as an anchor for his brother, or that Rin is basically invisible to 90% of the population.

This story takes place if when Rin discovers his heritage Satan succeeds in dragging Rin into Gehenna. Rated M for graphic content! (you have been warned) This is my first time writing a fanfic so reviews would be greatly appreciated!

A story about Rin being exhausted and everyone else being annoying. Starring an angry Rin Okumura and his trusty sword sidekick. Rated a high T for Rin's language, because it's Rin and there's no getting around it.

What if instead of being 15, Rin was only 9 when Satan sends his demons to retrieve his son. But this time there's no Shiro to protect Rin, and our favorite half demon ends up in Gehenna. As he grows up inside Gehenna, Rin makes the best of his situation; he makes friends, gains strength, and desperately tries to get back to Assia to see his brother and family.- Blue Bloods

In which God has a wicked sense of humor and the Vatican is not amused. List with snippets attached. Everything goes. Including the cast of Ao no Exorcist's sanity. Rated T because Satan is a very bad parent.

AU Where Yuri survived and is raising Rin and Yukio with the help of Father Fujimoto and Mephistopheles. I'm bad at summaries.

When you hung around people who battled demons for a living, weird conversations were the norm. Stupidity however, had no bounds especially when Rin was involved. "Wait. If you're the son of Satan does that make you…the antichrist?" People start asking the real questions.

(AU) Rin, the youngest child of Satan, is captured by the exorcist and they plan to use him as a weapon. Yukio soon rescues the boy and grows to care for him. He tries to keep him hidden from both Satan and the Vatican, but it's hard when demons, exorcists, and a group called Witches is after him. But who are the witches and why are they after him? (I'm bad at summaries)

Rin is born in a different time and a different place and yeah lots of things are different.

Rin is transported to Berk by Mephisto's malfunctioning cuckoo clock. When he gets there he is faced with hostile inhabitants, fire breathing dragons and a language barrier. How in the world is he supposed to get out and back to Japan before these 'vikings' decide that he's too much to handle?

Yukio overhears something disturbing in his dorm room. What will he find inside? Pure randomness, contains mutilation of innocent sweets

Having his execution sentence lifted was great and all but why did he have to deal with Angel of all people? Far away from home, alone, and grumpy, a certain Demon King comes to make amends—as much as one can under threat of death by his older brother—and hilarity ensues. An ApprenticeRin! with a dash of Lightning sarcasm, a drunken Angel and an obviously socially-inept Amaimon.

Rin is beginning to develop a crush on Mephisto, something that really pisses him off. When his grades begin to slip due to his lack of focus, the latter is forced to confront him on why. Mephisto could have never guessed it was because of him.

Being both a demon and a human, Rin has the strengths of both. He also has the weaknesses.

When Rin Okurmura starts to feel urges that he shouldn't be feeling, he realizes that he is going through puberty. This is no ordinary puberty though, it's demon puburty. With hormones raging, will Rin find love or will what he finds or does be meaningless? RenXRin. RinXYukio. RinXAmaimon.

Rin enters Maiting Season for Demons and Shima gets strangely attracted to him. First Multi-Chapter Story.

Okumura Rin was entered into a boarding school at the young age of 5, but the boarding school was a lie and he was mercilessly stolen from the clutches of his father. Now, 10 years later, he has been found a cold and merciless killer; an assasin. Can he be the exorcist they need to save the world? Or will he destroy it before Satan can?

Amaimon begins to feel jealous of how Rin cares for Yukio and demands the same treatment. They are technically brothers, after all.

Amaimon has theories about Rin's life and decides to spill his inner thoughts shortly after kidnapping him for his own amusement. Things take a terrible turn and Amaimon is the cause. Rated M for future chapters probably.

Okay, who thought the son of Satan should be allowed near those summoning circles? Oh boy, here comes trouble.
