He's actually quite good at it, demonic tendencies and hyper-possessiveness aside.

But he also didn't lose everything. Sequel to Nemesism

They always scroll at him for falling asleep in class. They call him a slacker. All of them think he doesn't want to pay attention. Yukio always says he sleeps to much, that he should focus more on his work. But no one of them know what's like to be awake until the sun begins to rise. But he guessed he sleeps when he is dead.

Rin has tried his brother's patience one time too many. A recent prank as well as his bad habit of sleeping in class have finally left Yukio with no choice other than to teach his brother to not sleep in his class.

Not everyone gets the opportunity to visit other worlds. Well, unless you stumble across a certain 'Merchant' at a convention, then you're guaranteed to be sent somewhere interesting. Sadly, in my case, I never even made it to the convention, getting caught up in a car crash'll kinda ruin anyone's day. Fortunately for me, I was able to take a shortcut. {multi-cross elements}.

"A demon who's completely loyal to a human, who does whatever his human tells him to is called a familiar. Exorcists don't kill familiars. If you become my familiar, I will be able to protect you" Rin froze. "Would that mean I'll have to do my homework when you tell me to?" Rin shuddered in fear. Yukio smiled happily and nodded. AU. more inside.

The next thing they know, they're in a world of wizards, magic, and adventure. Meeting new friends and making some enemies, maybe this is the new start that Rin needs.

When Saitama starts his very own Youtube channel, he has no idea he's jumping into a pit full of snakes. [AU] [Saitama/Genos]

Rin wasn't sure what was worse in this new world: the shady adults, the weird students, the bizarre transforming weapons, or the homicidal demons called "Grimm." At least Kuro was here to keep him company. *Spoilers for Blue Exorcist manga*

Living the life of a demon comes with a lot of banes and boons, but it can be pretty handy when you have some extra features. Rated Teen because I'll probably curse a lot and there will be mentions of gore. *Don't be fooled; lots of angst, /plenty/ of whump, as well as humor and friendship/family. :)

Once you're staring death in the face, remember to look into his eyes. Your painful look will break him.

In short, this is a scenario where Saitama is instead given S rank instead of C at the Hero Association Exam. Kinda written on impulse, but will be updated anyways. Ciao!

Right now, he didn't know what to do. But he knew he would push through the pain, and no matter how many times it would take, he would save those he loves.

There are a lot of things that people, upon becoming parents, might attempt to keep secret from their kids: a tattoo, a criminal record, or even something as simple as the fact that one dyes their hair. "Does this mean I can dye my hair now?" "I think it does." "No, it doesn't!" (T for language.)

AU When Harry is fighting Voldemort for the Philosopher's Stone, he makes the horrible discovery that he is keeping Voldemort alive by hosting a fraction of his soul. What is the rest of Harry's time at Hogwarts like when he knows that he has to die?

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.

There were only two people Rin could trust and tell his every heartbreaking secret too; his father, Shiro, and twin brother, Yukio. So when he overheard them talking about him and his true nature, he slowly started breaking, losing himself, and changing. He got stuck in a whole other mess, one he wouldn't dare try involving others in. AU-ish.

Hisashi Midoriya, or more notably "All For One" has made a terrible mistake in his plan for One For All's eventual descent. He let his emotions get in the way of his goal. Now he tries to gain back what he has lost to the light. His son. Izuku Midoriya. (All for One Izuku)

Katsuki has always loathed Midoriya with every fibre of his being. He has always felt an undeniable hatred towards him, so why exactly does he suddenly want to know how it feels to hold Midoriya's hand?

All the half demon wanted after school was some toast.

Rin takes Yukio to the dentist after he cracks a tooth. Anime continuity.

Undyne runs into Sans, who is staring out into the abyss. And while at Grillby's she discovers one of his dark secrets. For the most part, Sans doesn't seem care much at all either way and that's the problem. Papyrus and others get involved too. Self-harm, suicidal thoughts. Dark themes. Semi-lack of puns.

But that is impossible. Even he can't protect his brother from the truth. In short, Yukio is the one who inherited Satan's flames. My first story :P Hope you enjoy it

Rin knew what it felt like to be betrayed and he was used to it by now, he just wasn't used to it hurting this much—why did it have to hurt so much? Set after the Camping Trip Arc. Not your common cliche. [AS]

Winter is coming and the old dorm building is completely unequipped to provide comfort for the twins, no heating, no hot baths, just their annoying other half. Can the cold weather spark some warmth inside their hearts?

Rin had an extremely tiring day fighting swarms of demons without being allowed to use his flames. well enough is enough. finally he draws his sword and throws his sheathe down on the ground in irritation. He'll find that was the wrong choice when later he goes to sheathe his sword and- wait. Where did his sheathe go?

A new state alchemist appears. And he's very, very... peculiar. Now that Roy is assigned this strange man, what hijinks will unfold? How many hotdogs can be stacked on the Colonel's head while he's asleep? ... And what is the man's true goal?

What if Rin was the exorcist and Yukio had the secrets kept from him? What happens when he finally figures everything out? How are things different? Yukio is obviously different from Rin, so things probably won't play out so drastically. So what happens? (suggested by Upper second Rin)

At a young age, Rin is diagnosed with a terminal illness. / Rating will probably go up in the future due to graphic content.

Rin has been having a hard time since his demonic secret got out. His friends won't acknowledge his existence and his brother has been giving him the cold shoulder. How much more can Rin take? This story does have self harm and suicidal actions. Amazing cover art by LittleFireOfLife.

But while controlling a water demon migration, things become complicated. Especially when Rin has to make it out of Gehenna and find his friends that may or may no be trapped there with him, all while learning about his demonic heritage.

Sometimes, it's really hard to keep your head above the water when the weight of the world in on your shoulders. Rin Okumura knows that feeling all too well. In other words, this is another way Suguro and Rin's fight could've gone in the Deep Keep. Bless you, Torako, you scary mother, you. Slight BonRin?

Rin has an idea in the middle of class, Yukio is suspicious, and both of them hate the rule of twins. What one twin feels in the physical body so does the other twin. Yukio has never wished death upon his brother more than now. [One-Shot]

Take away their different hairstyle, different height, Yukio's stupid glasses, and Yukio's stupid moles and they will be the same person, right? They are twins, after all! - A story where Shima teases Rin for not being very twin-like with the young Sensei and Rin is determined to prove that Shima is wrong.

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.

"I expected you to be there! You said that's what friends do! And we were friends! ...weren't we? Weren't we at least friends? Or was it…was it a lie, when you said that? Was it just a lie...? Or am I...just an exception?" Mostly just Rin being depressing and ranty, but has a little BonRin in there.

Saitama ends up crashing our favorite fanfiction site with one blow. Whoopsies.

Going to the roof is calming for Rin. It helps him clear his head, most of the time. The weight of feeling alone is getting to him. None of the people he cares so deeply about, feel the same way and he is starting to lose hope, fast. One-shot. Warning, this story has suicidal thoughts, self harm, and attempted suicide. Amazing cover art by LittleFireOfLife.

In which Rin sets out to annoy Bon and ends up going to a magic show with him instead. Not that he minds. This is a sequel to "Of Tired Demons and Death Threats" and "Of Hungry Demons and Homework Assignments", just so you all know. Rated high T for Rin's language.

Rin Okumura had been doing fine in terms of friends, in terms of school, in terms of his steady pace in the art of Exorcism... but all that changes when something goes wrong during a seemingly simple mission, causing him to crash and burn among his own flames, so to speak. WARNING: There is drug use and self harm/depression themes in this story, full warning inside BEING REWRITTEN.

You'd think Bon would have been more cautious after the whole "zero-sleep" incident, but no. He wasn't the least bit worried. And that was his own mistake. A story about a hungry Rin Okumura and an ignorant Bon. A sequel of sorts to "Of Tired Demons and Death Threats". Rated T because, once again, it's Rin Okumura, and also Bon.

The Exwire class is brought together, or rather, taken hostage in order to watch their series, Ao No Exorcist. (NO PAIRINGS)

Being raised mostly in Gehenna, it was no surprise that all Rin knew about Assiah was what he had learnt when visiting Yukio- but Suguro 'Bon' Ryuji didn't know that. He just wished his strange roommate would take becoming an exorcist seriously! [AU-ish]

Soulmate!AU with a bit of canon tampering. Nothing major, but BonRin soulmate love with a twist. Rin feeling despair for his complicated situation and no one knowing why the resident half-demon is acting weird...except Bon. Rated T for language and mentions of self harm.

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.

(An idea that came from Reading Pixie, not me) Rin and Yukio go through the portal to meet their real dad.

What happened after Father Fujimoto died? How did Rin cope with his new identity as a demon? Was Yukio there to comfort him or did he keep a cold distance? Takes place between Fujimoto's death and his funeral (and possibly beyond).

After the destruction of A city, comes the time for reconstruction. Everything is back to normal, but Genos notices a subtle change in Saitama. Something is wrong. And he's going to fix it. [Pre-slash - Genosai]

Shima used to think that he could trust Rin. Rin always thought that he could trust Shura. Too bad Mephisto's decision to trust both Shura and Shima turns out to be a very bad one on a particular occasion.

It's been three months since the camp and Bon is getting really frustrated. He and Rin both know that their feelings towards each other are completely mutual. So why does the blue-haired teen keep pushing everyone away? Will a mission in a remote mountain village bring them finally together or tear them apart for good? BonxRin. Rin never revealed himself.

Shiro returns from a coma. His first reaction is to punch Rin. Requested by 27kirune.

This takes place when Rin and Yukio are 21 and graduated from True Cross Academy.

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.

I can't keep doing this. You'd think that, by now, I would have realized that I should just stay away from people. No matter what I do, I hurt them. And then they hurt me back. (TRIGGER WARNINGS: SELF-HARM, ATTEMPTED SUICIDE, DEPRESSION) (Also, may contain cursing.)

Sharing a room with his brother for fifteen years had taught Yukio how to deal with many things. The effect of nightmares on a newly awakened pyrokinetic wasn't one of them. [Oneshot]

Edited Ch 1-11/14/15 Rin's got his sword back, and there's something different about it that he doesn't notice until it's almost to late. Warning: Rin/Bon pairing! Yaoi! Blood/Gore. This short story is for LilCKsunshine!

I'm sorry! I uploaded the wrong document by mistake...thanks for the reviewers pointing it out! This is a retelling of the Kyoto arc with changes, focusing on the fatherly relationships and friendships. Enjoy!

5 times Rin acted strangely and 1 time it sunk in that he was raised in a Monastery. (Happy Easter)

Truth just won't let go of Ed. Ever since he let it posses him to yell at the wizards, it treated him like an errand boy. And what's this thing they're calling a Gate? Semi-sequel to Even the Wizards must pay their due. Rated T for Ed's swearing. This is a stand alone in agent of Truth, and it is complete!

For Rin and Suguro, friendship is more like a battlefield. As with most things involving his brother, Yukio is becoming resigned to this. No pairings. [Oneshot]

"Did you say worm?" Rin asked. Yukio's explanation had some other heavy stuff, but Rin browsed over it selectively. "I have worms?"

A fight between Bon and Rin turns into something a little more dramatic. No slash.

Rin Okumura is tired of being referred to as nothing but the son of Satan by everyone – including Yukio. Why can't people see him for who he is, not what he is?

Rin was taken by Mephisto and Yukio to Hatagaya to watch over his progress as an exorcist. They suddenly got their stomachs empty and they headed over to eat at MgRonalds, in which Mephisto Pheles got a reunion with his father whom he barely noticed. What would Rin's reaction be at his father's "generals"? Please give it a try

Shiro left a will with the Vatican to be read after his death- unfortunately because of the infamous bureaucracy the twins don't learn about it until almost half a year later. Another exploration of character development- this once centered more around Mephisto and Shiro's relationship. I do not own any of these characters.

The fear of forgetting or being forgotten— Rin-centric

In which Rin is your average fanboy and lets his imagination run wild. Every fans' secret (not really that secret) fantasy: To be a character in the show! One-shot. Disclaimer: I do not own either Fairy Tail or Blue Exorcist.

In which Rin's tail becomes the center of attention during class. Fluff and humor abound!

When a lonely little boy finds a sword that can talk to him, his entire fate changes. A sword that loves humans finds a half-demon child and decides to join with him. Things won't be quite the same for anyone, but is it a curse or a blessing? Crossover with Durarara.

If there's a person that's normally happy and outgoing, and always so loud, clumsy and reckless, but one day, they come in the room quietly, looking down, everyone tends to notice, or rather, they can't help but notice. My First Blue Exorcist Fanfic ever. Pls be nice. K for one word. R&R. PS: Slight OOC Yukio. Sorry, tried my best, so help me out, kay? Pls? Thanks.

Rin thinks some pretty weird things and is convinced Bon can read his mind. Oneshot. T for language.

"They'd try not to show it, but he could tell. He could see their muscles contract in fear, hear their voices become softer, and feel the tension grow with each step he took, so thick you could cut it with a knife." Has a sprinkle of coarse language, for those who aren't very fond of it.

No one had known a problem quite like this would arise. Of course the Son of Satan would be every demon-girl's dream come true. But Yukio will give everything so Rin remained ignorant, everything to keep him away from those banshees, those... fangirls.

The Okumura twins are more similar than you think. / Brother-bonding.

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

Rin's thoughts and woes on tail binding during his first weeks at True Cross Academy. Mephisto provides some useful tips.
