So…raise your hand if you're a fan of Doctor Who, Steins ;Gate, Future Diary, or any time travel show (or movie) ever. (Everyone raises hands). Good. Now that our little introduction is out of the way, let me tell you what I've been binge watching lately; Blue Exorcist. How does the question I just asked relate to that? Read on, my young one and find out.

Btw; unless specified otherwise, this is in Rin's pov

I stared straight ahead to see something that neither Yukio nor I had seen in several months; the monastery. Okay, we had seen it, but it was who was in it that was more confusing.

That's the old man…how?

This had to be a trick. He died months ago.

A few hours earlier…in the director's office…

"Are you sure?" A little green hamster asked.

"I'm positive." Said a demon wearing pink, way too much pink. "If this happens then he'll lose the wager for sure. He is the only one to ever win one of my wagers and I am not going to let that happen. Eins…zwei…drei!" He said, twirling an umbrella. A puff of pink smoke surrounded two people that he was looking at.

On the campus…

Rin and Yukio were walking back to their dorm room that had just been opened again. A few months ago practically everything had been destroyed in a huge disaster when Satan tried to, in a nutshell, destroy the world. The exorcists had managed to destroy the gate that was sending the demons through. The school was almost rebuilt and ready to open again. The twins were almost to the dorm when a pink cloud surrounded them.

"Rin!"

"Yukio!" The two reached for each other, but both passed out before they could find one and another.

Now…where were we? Oh…yeah…the monastery…

I looked around. Something, no, someone was missing.

"Yukio! Yukio, where are you?"

"Rin! Where are you?" He heard his younger brother.

"Where are you Yukio?" Rin said, looking around.

"I'm over here." He said, walking around the corner. "Do you have any idea what happened?"

"There was a pink cloud, I bet that the clown did this." I said. I began to wonder, why would he? What would he gain from…wait…what did he do? I looked up and saw Yukio approaching the monastery.

"Hey! Where the hell are you going?!"

"There's only one way to find out what's going on here. Also, tuck your tail in, just in case." I knew he was right, so I hid my tail and we walked towards the place we used to call home, only for me to realize at the last second that there were anti-demon charms.

"Wait Yukio-!" Was all I could get out before he hit the invisible barrier that surrounded the fence. He pulled his hand back in pain and I saw a few priests, including the old man, run out.

"Only a high class demon could trip the traps around the barrier, do you want us to grab some holy water?" I shivered at the thought. Even though I was only half demon holy water still burned.

"Wait! Dad! It's me, Rin! Can't you see?" I said, trying to get him to notice. He looked closer.

"RIn? Yukio? Is that you?" He said, walking closer. He looked stunned when his eyes saw the koma sword.

"Look, I have a bit more knowledge of what's going on than you do, so if you take the barrier down we can talk." I said. He nodded at the other priests and they began erasing marks that were drawn on the ground. Yukio walked through the gate effortlessly, so I figured that it was safe and walked in.

"I would like an explanation." He said, eyeing the koma sword.

"Fair enough, let's go to a place where we can't be interrupted, let's go to the basement."

"Rin, we don't have a basement."

"You know what I mean." I said and he nodded. Pushing various things around on the alter revealed a staircase and we walked down. He was silent until he checked on the sword in the drawer. When it was still in there, unopened, he sighed.

"Care to explain how I send the two of you to school and you come back a few years older and as demons while the koma sword is still in the drawer, undrawn?" He said, gesturing to the drawer. I walked closer to him.

"This is going to sound crazy, but I'm not exactly sure what's going on. How old am I right now?"
"You're thirteen, why?"

"Listen, if what I'm thinking is correct then we've been sent three years into the past, probably by Mephisto, but we're not sure." Yukio said.

"So am I supposed to assume that you two became demons at some point? Humans don't set off those barriers." He paused. "And Yukio wasn't a demon before, so what happened?"

"We're home!" They heard a voice say.

"Dammit, those two can't find out that you're here or it'll destroy the timeline, especially since Yukio just became an exorcist!" Dad said, frantically bolting up the stairs while trying to make sure that the two kids hadn't seen them. However, as the entrance to the basement closed I could see my little brother glaring at me, not the one standing next to me, the little one.

"Hard to believe, huh?"

"What is?"

"That you became an exorcist so long ago, I mean you were thirteen! How cool is that?"

"It won't be cool if little me starts going after you because he just saw is big brother as a demon in the basement that younger you doesn't even know exists!" After a few minutes of awkward silence the door opened again.

"I want answers, but that's going to have to wait till morning. Yukio's already on to you, so sit tight and we'll talk in the morning. Good night." He said while walking back up the stairs.

"Good night!" I said back. I felt tears in my eyes. I could save him! I could change everything! Then Yukio and I can go back and still be human! But I soon dismissed the though. That was optimistic thinking and could never happen.

After a few minutes of struggling to find comfort, I finally managed to drift into sleep. I wish Kuro was here, I miss the little guy already…That was the last thought I had before I was awoken by the door opening again. I wasn't morning yet, so it couldn't be the old man. I looked up to see little Yukio stomping down the stairs.

"Um…hi..?"

"Don't you dare talk to me you demon." He said in an incredibly cold way. I was about to reply when he pulled two guns out and aimed them at me. He was about to shoot when Yukio woke up.

"Stop!" He said. His younger self looked at him in a confused manner.

"That is a demon pretending to be Rin. Can't you see? I'm an exorcist and we destroy demons."

"I said stop."

"Why are you helping it?"

"Maybe it's because, I learned to tell the difference between the good demons and the bad ones." He said, letting his black tail peek out from behind him. He smiled and showed is fangs to himself. His younger self gasped and dropped the pistols. He stumbled backwards and started crawling away from his older self.

"No…there's no way…I'm not a demon…I-I just can't be one…right? Right?" He said, confused and stunned. The words barely making a sound above small squeaks and noises.

"No, Yukio, you aren't a demon. Not now at least." I said, petting the poor guy's head.

"Get away from me! What did you do to me? Dad says that I didn't inherit the flames! How could I possibly turn into a demon?!"

"It's all right, like I said, I've learned to tell the difference between a good demon and bad one, and it was thanks to Rin over there that I did. Because when he first became I demon, I tried to shoot him too." Yukio said to his younger self, who began to relax a bit, but then his instincts kicked in.

"What am I doing? Talking with demons like they were my friends or something! I don't know what you two demons did to me and my brother, but I will never turn into you! Never!" He said, running out of the basement and closing the door behind him. His words stung like poison in the two's minds. Yukio was no scared of his older self and had tried to shoot Rin. The worst part was, is that they didn't even have an explanation for how they got there!

"That could've gone worse."

It's an over-used idea, I know. But I like the setup that I have going. Seriously, if younger Yukio met himself and Rin from after the anime I don't think that he would be too happy knowing that he would become a demon. It's like how Yukio was about to shoot Rin in episode 3. I know that I have other stories that I haven't updated in a really long time, but those take too much time to make a chapter or I have writer's block. I am planning a Blue Exorcist fanfic for my Lea universe where the only daughter of Satan trains to become an exorcist with her demon brother! Not original, I know, but I have some (evil) ideas. Muhahahahahahahaha!

Yukio: I think that she's finally lost it

NM: I lost it ages ago, by the way, when I said that I have evil ideas, they're mainly ways to torture you in bonus chapters

Yukio: That's mean! Why would you do that?

NM: Because we got to torture Rin adjusting to being a demon in the show, but there is a serious lack of fics torturing you

Yukio: :(

NM: Muhahahahaha! And if you were wondering, my torture methods include; fighting with your own tail, holy water hand grenades, and embarrassing videos of you being shown to your whole exorcist class

Rin: I'm not getting tortured, right?

NM: Nope! But you will get to see the video of Yukio almost shooting his own tail off before he realizes what he's doing

Yukio: WHY MEEEEEE?!
