Yeah I know I should be working on A Strength of Will but ever since I watched the Black Rock Shooter OVA and the anime, (and read the manga) I have been itching to write a crossover with Rin and Black Rock Shooter in it. So my dear readers, I advise you watch the OVA first (since in my honest opinion, BRS is more awesome in that plus it's shorter than watching eight episodes of the anime), because I will mostly be basing this story on it (the OVA, anime, manga, and even the video game all have different story plots so it is confusing!). You can find the entire OVA on YouTube too. And I am also going to change it up a bit so that this story goes smoothly.

I do not own the characters of Blue Exorcist or of Black Rock Shooter. They belong to Kazue Kato and Ryohei "Huke" Fuke respectively.

WARNING: This story will be rate M for mostly language, and gore. And maybe some romance too haha. ;)

Alone.

It is truly one of the most unique words of the human language; there are many definitions and meanings to it. In the Otherworld and to its inhabitants it means to be separate, apart, or isolated from others however, it does not mean it bothers them. Most actually prefer it…but that doesn't suggest that its denizens are always alone.

For Black Rock Shooter and many others of the Otherworld, fighting is their way of life; it's the one thing that seems to keep them going. So it was no surprise that when she was trudging through the graveyard of nameless crosses that she was attacked by an old enemy. The black pigtailed girl was just able to intercept Black Gold Saw's King Saw blade from tearing into her back with her own Black Blade but was unable to hold her stance and was sent flying into a nearby cross from the force of her opponent's blow. Red eyes just watched her impassively as she got back up and into a fighting stance; they then roamed onto the two scars that decorated the shorter girl's torso, a ghost of a smirk appearing on Black Gold Saw's lips. Seeing where her challenger's eyes were resting, Black Rock Shooter's grip on her sword tightened as blue eyes narrowed, the all too familiar flame bursting to life in her left eye. No words were exchanged between the two, there was no need really it only got in the way, and within seconds the two fighters were clashing against one another. Loud metallic sounds of two swords colliding with one another over and over again as their owners' put all their strength behind each attack. As Black Rock Shooter deflected her foe's strikes with the Black Blade in one hand, she was charging up her Rock Canon in the other. Before she could launch her attack though, Black Gold Saw kicked her cannon to the side so that the blast was fired in another direction, the taller fighter then smashed Black Rock Shooter's face in with the flat side of the King Saw blade instantly breaking her nose and sending her flying once more. It seems that even though I have gotten stronger, she is still a notch above me. She thought as she tried to get up once more only to fall back down as her surroundings swirled around her. The pigtailed girl suddenly began to feel very dizzy as her vision started to blacken around the edges as consciousness slowly slipped from her. Yet before she completely blacked out she didn't miss the look of genuine surprise from her opponent…

It was just another day at Cram School for my fellow classmates and I, except the fact that my brother announced that the class was going to do a week long boot camp to get ready for the Exwire exam. And after Yukio handed out a packet for us to fill out on what Meister we were going to specialize in, I had to learn the hard way what he was talking about: aka Bon yelling at me and calling me an idiot. Well sorry if I don't know this crap. I thought after the three Kyoto boys explained to me what Meisters were. Then to make matters worse, this creepy teacher with an eye patch comes in and starts talking about magic circles while he starts to draw one. When he announced he was going to summon a demon from it I was in awe but when the guy actually did summon one, my mind was blown away. I mean he just summoned this badass looking demon dog, it was so cool! I began to slightly panic though when the guy mentioned a test but relaxed after the guy explained what we had to do. When Eyebrows summoned two white foxes Shiemi and I were couldn't tear our eyes away from the awesome sight. I couldn't help but snicker a bit when Bon said that had no luck with summoning along with Konekomaru and Shima. I was also very proud for Shiemi when she enthusiastically summoned what the teacher called a Greenman Spirit. I frowned though when I realized everyone was staring at me.

"What?"

"Tch. You haven't tried yet idiot!" Bon growled as he pointed to my blood free paper.

"Oh." I murmured as I looked at the summoning circle on the piece of paper I held. I was about to bite my thumb and try it when a sudden thought hit me:

What if I summon something really dangerous with my blood?

That very thought alone encased me with fear as the image of my foster dad being possessed by Satan flashed before my eyes. If that were to happen then I would never forgive myself! I was about to ask if I could pass on doing it when Bon took a pin needle and stabbed my thumb. "Just do it already! We don't have all day Okumura!" He snapped with aggravation. Throwing him a "fuck you" glare, I decided to get it over with and chanted the first thing that came to mind.

"Stand beside me and help me fight, girl with fire eyes that burn bright."

When nothing happened, I just slumped my shoulders in defeat. I straighten back up though when Bon began to laugh hysterically at me. "What kind of dumbass chant was that?" He gasped between fits of laughter as my cheeks burned from embarrassment. I was about to punch him in the face when the teacher dismissed us for the day, not before Bon made fun of me some more. After everyone left I calmed back down; I decided to stay behind to wait for my brother so that we could leave together. As I waited for Yukio I couldn't help but to stare at the summon paper in my hand with disappointment. I really felt like I was going to summon something when I said that chant! "Ready to go Nii-san?" Yukio asked once he entered the room and collected his stuff. I just let out a sigh and nodded but before the two of us could reach the door a bright blue light engulfed the room. My first thought was that it was Satan coming back to drag my brother and I to Gehenna but when the blue light disappeared, that thought instantly died. It was replaced with a new thought as I stared at the new arrival in the room.

Shit, what have I done now?

I can already tell I am going to have a lot of fun writing this story haha.
