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)

AU. When Rin was six years old, he got into trouble at school. Fearing the disappointment of his father, he did not walk home with Yukio; instead, he took a left turn-and future events started to shift. Rated T for safety.

In a land of myth, and a time of magic, the destiny of a great kingdom rests on the shoulders of a young boy. A twelve year old boy, to be exact. When Arthur attacks a Druid camp and is saved by a young boy, he has no idea the destiny that has drawn them together, nor how much the boy Merlin will come to mean to him. AU.

Mephisto X Rin X Amaimon Yaoi One sided Malphas x Rin

Since the dawn of time, the armies Heaven and Hell have been at war. But when humans emerged, angels retreated to Heaven, for if their battle continued, many humans would die in the crossfire. But now, it is time for Heaven to declare battle against Hell once again. But who will win? The Lords of Heaven, or the Dregs of Hell? And which side will the son of Satan find himself on?

Rin is taken away to Gehenna when he is a baby. Unfortunately, they can't obtain Kurikara. The young prince gets raised as a human by Satan and fifteen years later he has to go back and get his demon heart, so he can gain his demonic powers and become the worthy son of Satan.

Prince Arthur has been raised to one day rid the land of sorcerers and their magic as Uther wishes. He's meant to find and bring in Emrys, The Dragon Prince. Yet when he and Emrys meet it is nothing like he had come to expect. It is immediately clear that they are not friends but maybe not enemies either. Sequel to Moment of Chance. Can be read as stand alone.

Demons, Angels... Rin had pretty much seen it all. Too bad his family had no idea what he knew. Or who he knew. Archangels.

Slytherin!Merlin. Gryff!Morgana. RETURNING TO STORY AFTER 2 YEARS.

Inspired by ef07's Blue Fire. There are infinite universes out there, each just as beautiful and unique as the others, but Satan inevitably falls from grace in all of them. It was at least believed Assiah was lost to him, or so they thought. Rin Okumura, although thought to be the spawn of Satan, little did they know he was Satan himself. First in the Revelations series.

A new king rides through a village and finds a mother and son somewhat fascinating. The developing relationships might be enough to change the course of the future, as Merlin becomes a prince and Hunith almost a queen. I'm what iffing... again!

31st October 1981: Lord Voldemort is dead. The world is full of chaos, fear and grief. James and Lily Potter, who ended this war, have a life to repair.

Mephisto finalized his plan of sixteen years by trading Rin to Satan for his freedom, but things quickly fell apart. Now Yukio must find a way to rescue Rin from Gehenna, and Rin has to stay alive as he's trained to be the Prince of Hell - but what if he forms an alliance and decides to overthrow Satan's rule instead? -some chapters are rated M b/c of gore in some chapters

Rin lost control at the exorcist training camp, his father is dead, and he lost the friendship and trust of those closest to him. How does one carry guilt, face the consequences of past actions, and keep yourself from falling into despair and drowning? Seeking an escape from reality, Rin turns to the last thing anyone expected. CURRENTLY BEING EDITED

AU where Rin found out that he was the son of Satan early on and became a spy for his father.

Hey everyone. So this is going to be a Blue Exorcist Mini Fic. I am planning on changing a few things. Rin will be female, have more control over the flames, and have depression and anxiety. There are trigger warnings in this Fic for suicide, self harm, cutting, overdosing, pill popping. As by the title Rin will be with Ryuji. I have no proper title for this.

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 Uther genuinely believed that Merlin was his own son, and raised him as a prince? Series AU. No pairings except for canon.

Even after his friends accept him as the son of Satan, Rin still faces his regret, fear, and disbelief. WARNING: Contains depression, suicidal themes, and strong language.

Coincidence. The prefix 'co' comes from the Latin 'com' which means "together," and incidence refers to an event or occasion. What we think of as chance encounters, turn out to be something much greater. Changed to "T" so more people can read. Chapters with mature content will be marked!

Merlin is de-aged by a sorceress, and left as an innocent five-year-old. It's down to the Knights and Arthur to protect him in his younger, vulnerable state. But with interfering Druids, the looming threat of Morgana, and dangerous suppression magic, are they fighting a loosing battle? Merdred Merlin/Mordred

When Satan is told that Rin is now in the care of Mephisto (helpfully supplied by Amaimon) He decides to send Amaimon on a mission to retrieve Rin. So, what will happen when they finally meet? (I'm not the best at Descriptions so just read it?) [AU with only small bits of canon] [Amaimon x Rin] [Obvious Yaoi... So if don't like it than don't read it?]

Full summary is inside. I will just say that it involves Yukio and his little half brother Rin. Read and find out more. Will be a series of one-shots and arcs.

Gehenna and Assiah have always been described as mirror dimensions. And what is a twin but the reflection of the other twin?

A rewrite of the first part in my Dark Prince Trilogy. What if Wormtail hadn't told Lord Voldemort the Potters hideout. What if he took Harry straight to him instead? Book One of the Dark Prince Trilogy.

"My, my, this is really extraordinary," Mephisto commented. "Never thought Father's heritage would resurface again." Blue flames, tail, and sharp teeth against Grace, halo and wings. Because some say that Satan once was an angel of Heaven so the idea that one of his children might inherit his Grace isn't far from impossible. Nephilim!Yukio. Full summary inside!

Father Fujimoto never told Yukio about the twin brother who died as a baby. Yukio never tried summoning. The Monster had never bothered to hope for escape- until he found himself being cared for by people wearing his captors' colors. He didn't trust this to be reality, he'd take the break even if it was a psychological attack.

Zeus kills Sally Jackson with his master bolt when Percy is six months old, drastically changing Percy's life and the course of his future. AU.

[post!1stanime] It wasn't long since they defeated Satan & closed the Gate. As Rin still tries to repair his relationship with Yukio one night something happens. Aftermath is devastating, it seems that history likes to repeat itself but this time with a wicked twist. It's like they say: You're only given a little spark of madness. You mustn't lose it. Rin doesn't. [rinyuki]

When Harry faces down Voldemort in the Ministry, A mysterious man by the name of Emrys defeats Voldemort in place of Dumbledore. When the man becomes the new Defense Against the Dark Arts teacher, Harry's year becomes far more interesting, but yet so much more sinister. Rated T for Violence and Swearing.

He's always seen the strange, horrific looking creatures for as long as he could remember. Feelings of déjà vu always come and go. And he just doesn't know why. Or at least he didn't, until he came to True Cross Academy on a Student exchange programme. [Sequel to Trust]

in an age where demon kind have become enslaved in Assiah, a rescue organization known as eclipse who find and help free demons from cruelty find an old demon. But as they learn more they find out its not just any slave they have found, but the first demon to ever become a slave almost 500 years ago. Akuma of the blue.

The Vatican has constructed an underground utopia for the purpose of studying and protecting demons. At least, that's what they told Rin after erasing his memory.

"When has the Vatican scheduled my execution again?" - because on top of homework and sleep deprivation, he also had to worry about Satan dropping him off at cram school like he was five years old. Rin Okumura was: Not. Amused. [One-Shot]

When the people Rin cares about the most leave him, he resorts back to old habits: cutting. When his friends all find out, how will they react? Will they try to help him, or just let him go further down a path that eventually leads to suicide?

After Rin's fight with Amaimon, everyone discovers Rin's heritage. Rin starts to become depressed, but learns to accept it and adapts to the loneliness. He begins to pray to God, his only comfort, to remove some of the loneliness. Follow Rin as he learns to use his powers for how they were first intended. After all, Satan was an angel before he became a devil.

After Rin's friends found out about his father, they ignore him. He knows it's his fault, and he knows that he's broken. He knows that if he messes up, Yukio will kill him, so...why not start now? Angst!Rin Oblivious!Friends

A demon attacks the Exwires at the dorm, taking Yukio as a hostage and forcing Rin to reveal that he is the son of Satan.

Post-anime!AU. On return to the Academy one year later, Ryuji finds out that Rin has dropped out and moved to the neutral 'Middle Strip' between Gehenna and Assiah after Grigori's latest 'test'. While faced with secrecy and a new project, he must also learn some things only Rin can teach him (if the half-demon is not broken beyond repair). Dark themes, substance abuse, lemons.

Merlin takes the job of Defense Against the Dark Arts teacher in Harry's fourth year at Hogwarts. He will have to try to blend in, keep the school safe, and stop what he suspects will be an incredibly disastrous event at the end of the year, all while continuing to wait for his King to return. Basically my take on what would happen if Merlin taught at Hogwarts.

"welcome to Assiah, Earth colony 3, 2100 years after first settlement, but as per usual, humans came and messed everything up." burning shades of neon blue (Cyberdemon 2100) is a cyberpunk style story set around Rin Okumura, a young man desperately trying to discover the truth about his origins

Rin Okumura, son of Satan and heir to the throne of Gehanna disobeys his brutal father once again and pays the price. he decides to flee to his brother mephistopheles or 'mephisto ' in Assiah. Meanwhile an ancient evil attempts to puppet Rin and he meets a girl with a passion for gardening and a trigger happy exorcist(M for violence and language)

Rin passes out before he can destroy the Gehenna gate.

What happens when Rin is taken as a baby by Mephisto? What happens when he is made a full demon, and Yukio a full human? What happens if Rin was raised in Gehenna? This and more in Blue Flames and Pink Smoke. Adopted by Star-Nebula42

The Vatican found out about Rin when she was twelve and demanded her to be sealed away. When she's released from the seal by demons seeking to bring her to her homeland, she must choose a side. Fem!Rin, AU

Inspired by ShimmeringCrimson's Redirecting Fate. Rin, at the age of seven, finds out she is the daughter of Satan by being introduced to her first demon, her older brother. Fem!Rin, prologue to A Different Beginning.

AU Where Rin Grew up in Gehenna and Is now A demon king, one day he was just going through his boring daily routine when something crazy happens. i will update often.

The castle was at the bottom of a lake, deep in the water demon's territory. Some parts of the castle were warded by a magical barrier which held the water outside so the visitors could move around. But some were under water enabling only water demons to enter them. And of course, there were parts which weren't supposed to be under water but was flooded every now and then. Fem!Rin

A realistic AU for a Season 2 Blue Exorcist. Changes in the teens becoming adults, school classes, solving problems, exorcising demons, and lots of lies! Yukio & Rin develop feelings for one another, and the story of how it came to be. A true romance and story line canon combined into one. Warning: This involves Yukio x Rin. Don't like, don't read. I don't own Blue Exorcist.

Six years old Rin found a demon summoning paper and books in Shiro's room. She accidently called out a king of hell while playing with it. Poor child is now stuck with a bunch of overgrown childish hell king popping up at odd times. What's more? They think she is their youngest sister and want to take her home. (smart fem Rin, protective brothers)

All of Shiro's sacrifices ended in vain on that faithful day. Yukio shows up but he was far too late and Rin was already pulled into the gate. What will happen now that Rin is lost? This is a complete rewrite of my other story "Welcome to Gehenna! Shippings WILL include AmaimonxRin.

Rin hates speeches. Especially long, boring, political speeches given by his father, the king of hell.

There was a rustling in the corner of the dark room. Heavy breathing was heard. Teeth sparkled brightly in the shadows of the room. "I've missed you guys." Screaming, crackling and sizzling, and a volley of shots were heard that night. In the same corner the figure once stood, a girl had cried, "You'll always be my hero, even though you've lost your mind!" Silence. Then insanity.

Rin Okumura is an abused 15 year old boy who lives his father and brother. Yukio Egin lives with his mother and priest Shiro Fujimoto in a monastery. Yukio and his friends met Rin but ignored him like everyone in school has. Until tragedy strikes and brings them together, secrets are spilled, friendships builds and possibly love? Cover belongs to it's original owner.

Rin's lost all hope he could ever find, his friends have abandoned him after the revelation of his demonic powers, his brother has no need to cover for him anymore and it's all just too much for Rin to take, pretending everything's all right when in reality he's just drowning in his own sorrows.

My first fic so be nice. Rin gets hurt and Amiamon retaliates

No good deed goes unpunished. The battle doesn't end with the portal being destroyed and Rin finds that despite what good he's done everyone is quick to point fingers at him and Yukio being the one responsible for everything that happened. Running is the only option...but what now?

When Shiro had Exorcised Reiji, everyone thought that Astaroth was gone. Oh, how they were terribly wrong. [AU but actually based off/is a continuation of the Blue exorcist short Ura-Eku special 10] [Rated M for language] [Re-write for Business in Assiah]

Summary Rin is kidnapped and tortured for four weeks, before he is saved by his guilt ridden brother and the others. How will both of them react to the guilt from their fight? They will have to decide fast, because the man who tortured Rin is back for more

A new king of Gehenna has been crowned. A brother has been lost. But, neither situation is going to go unchallenged. (Just a story fragment that may not be expanded.)

"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.

It was a simple mission. One they could easily execute. Or so they thought. Getting caught in the grip of Gehenna, Rin disappears, leaving his brother and friends behind. Meanwhile, something else is stirring in Assiah! What will become of Rin? Rated M for violence and explicit scenes.

What if Satan and Yuri had planned and faked her death so that he could bring her to Ente Isle? But eventually both get sent back to Assiah, but separated once again. However, how are Yukio and Rin brought into this? How are they even going to react to their parents in person! Yes, Satan from DPT is their father here.

As an infant, Rin was taken from Yuri as an infant to Gehenna, and no one knew of Yuri's affairs with Satan. Yukio was found and raised without any knowledge of his parentage by Shiro Fujimoto, and was still able to see demons and to train to be an exorcist. However, he waits till the normal age to learn. Who else is he to summon but his long lost twin? Rated for paranoia.

Rin met his first demon at the age of ten and his life changed forever. How will he handle the truth about himself, the resentment he feels for his family and his time in Gehenna?

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!]

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!

After a dark battle the night before Rin had finally decided what he will do with his life.

After finding out about his dark past Rin and Shiro are running back to the monastery to escape the demons of the night.

In this story we see Rin find out about a hidden past which has been kept secret since his birth.

Satan managed to be there, the night that Yuri died. While there, he made a deal with Shiro. He would transfer Yukio's powers to Rin, and trap Rin's powers. He went back to get Rin nearing their forth birthday. Yukio promised then that he would destroy his brother. After all, his brother is a monster. Meanwhile, Rin wants nothing more than to be friends with Yukio again. Nice!Satan

Dragged to Gehenna when he's 10, Rin misses out a lot on his old world. But, after spending six years of his life there, Rin has no intention of returning to Assiah or becoming Satan's vessel. But Yukio has other plans, and Satan is hell-bent on subduing his youngest son.

Rin is a bored prince of hell, when one day his boredom is cured by a rogue green haired demon claiming to be a demon king of Gehenna. The demon breaks into Tartarus and steals an object of great value to Satan. Wanting it back, Rin volunteers to take the task. Eager to capture the traitor who has escaped to Assiah, Rin disguises himself as an exorcist in training to catch him. AU!

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

What if Rin picked a different path when Mephisto first confronted him? What would be the result? Some how he has ended up taking demon lessons and been charged with the task of protecting a certain tamer. Rin in this has a better control over his powers and is more demonic. RinxIxumo maybe other pairings Mangacentric

The demonic side of Rin is at it's breaking point. It isn't just his demon half, it's like another being sharing the same body. A bloodthirsty, murderous being that just wants to see the world burn. Because there'll come a day when Rin can't come back, and when that happens, there will be Hell to pay. (T for blood and gore)

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 Okumura - the happy-go-lucky, silly exwire who's always smiling. And the most un-demonic demon the angel Corinne has ever met. I don't own Blue Exorcist, only the plot and my OCs. Rated T to be safe, and there's gross descriptions of demons.

After his friends turn their backs on him when they discover he's the son of Satan, Rin becomes consumed by the dark thoughts of his own mind. If anyone can save him from himself, it's his brother. Oneshot. Blue exorcist and it's characters are (c) to Kazue Kato

But when it fails and leaves him with no memory how will the others react to the news that a certain green haired demon has taken him back "home"? And will Yukio arrive in time to save him, or will Gehenna finally have its prince?

AU. Yukio's sole reason for arriving at True Cross Academy is to find out why Satan killed his foster father. However, when Yukio reveals his power as a tamer by summoning the Prince of Gehenna himself- a demon who shouldn't exist- Well, everything just got a lot more complicated.

The Queen is ready and willing to make the sacrifice for the future of Camelot. But magic never weaves straight. Hurt!Merlin, Character Death.
