Happy new year 2015! Okay, I know that it was still early, but hey who care? Since look like I won't update anything until new year. Anyway, this story is my very first experiment on something and I can make it one-shot or maybe continue this as a series. Pick your choice. Like always please enjoy and review.

A gentle breeze caressing his face as it also slightly blow his messy black hair. Never once his blue eyes leave the beautiful blue sky which slowly surrounded by gray clouds, an obvious sign about something which will come after this. Rain. He can feel his lips started to form a small smile on his face when his mind mentioned that word. Rain. Ah, yes, he also remembers that it was also raining on that day, the day which leave him with so many questions and he glad that he finally able to find all the answer for the questions which already bugging his mind since that day. His blue eyes glance at the giant clock on the tower, the very famous Big Ben itself told him that he still has half-hour before the official meeting started. So, he close his eyes and let the breeze calm his nerves and let his mind remember that very day... The day where he learns something that he never thought he able to find in this very world.

"A dimension crack?" He can heard his own voice echoed in this very room, the room where he usually called whenever there is a mission waiting for him, but that was in old day as now he rarely called here since his rank has reach what he can said... The purpose of his life. The man who sat behind his desk in front of him stared at him with a mixture of seriousness and amusing in his green eyes which now only focused on him and himself.

"Yes that's right, I have felt this unusual feeling for this past few days, but I can't figure it out what it is until it was too late for me to stop it" The purple haired man explained to the young man in front of him about something that has bothering him this past few days. The young man which wear a white shirt with a black tie with red cross motif imprinted in the front of the tie, a black trouser with white belt and a pair of black boot as his footwear, only raise one of his eyebrows after hearing the purple haired man statement.

"Do you already send someone to check it?" The young man questioning before put both his hands which wearing a pair of black gloves inside the pocket of his black trouser. It was a habit of him which he sure will never be able to leave it as he still have the same reason since he start doing it, it made him feel cool.

"I do, as a matter of fact, I just send a group of Exorcists contain 10 people toward the location of where I sense this crack" the purple haired man replied before opening one of the dresser on his table and take out something before tossed it toward the young man who catch it with ease.

"See the the red circle I draw? That's where I sense this weird feeling which I believes to be a dimension crack" The man explained again while gesturing to the map which the young man hold and the said young man only raise one of his eyebrows again.

"You call it a circle?" The young man asks before showing him the map and pointed to something which obviously drawn with a red marker, but that 'something'... Is far from what we can circle.

"It wasn't the time for discussing my drawing ability" the purple haired man said and even though he said it in a calm tone, a thick mark already appears on his head. The young man smirked a little at this, it always fun to tick off this clown guy.

"Then Mephisto, let me guess. You are calling me here for checking it too?" The young man said after putting down the map, now his voice already carried a seriousness in it. If this guy calling him even after he sends a group of Exorcists, he sure there is something serious behind this dimension crack... Then again, WHY the hell they should to take care of something like this? Doesn't Exorcist job supposed to be only Demon-related? But... What if this crack come from Gehenna?

"Very clever, I suppose your deduction ability has increased. But, to answer your question, yes, I like you to check it too. I also can say that this crack doesn't come from Gehenna, but from another dimension which I never feel before" The purple haired man named Mephisto explained before flick his finger and then a key appear in his right hand.

"I afraid that whatever may appear from that's crack would be too much even for 10 trained Exorcists, so that's the reason why I call you here. As the current strongest Exorcist, it should be your responsibility for making sure that whatever may appear from the crack wouldn't be a threat for Assiah" Mephisto said again before throwing the key in his right hand toward the young man which once again able to catch it with ease. His blue eyes staring at the golden key in his hand, if what this clown said about this crack doesn't come from Gehenna then it was good, but this crack comes from another dimension which even this damn clown doesn't know or... He pretend to not know. Either way, what he said about him also true, it should be his responsibility for checking that whatever come out from this crack going to be a threat to Assiah or not. The Exorcists are trained to fight Demon, but against a creature that isn't a Demon... It would be a trouble for them. So, after letting out a sigh, he placed the key inside the pocket of his black trouser and turns around to gather his stuff.

"I believe you already make up your mind, so, I will explain that the key I gave you would lead you toward an abandon hut near the location of this crack, some walking on the north should be enough to make you see the crack. I believe you can take this mission, right? The newly appointed Paladin, Rin Okumura" Mephisto said while hiding his grin behind his folded hand as the young man know by the name Rin Okumura, strapping his trusted, blue sheathed sword on his belt, before swiftly wear his blue coat which contain several silver ropes and some silver buttons with an unique Exorcist pin on the right chest area, a true sign which tell any Exorcists that see him wearing his current uniform (not like he need it to be recognized as his face is easily to be remembered) that he is indeed the current holder of the title 'Paladin'.

"I believe so" Rin answered before walking toward the door, insert the key in his pocket and open the door, ready to face any possibility which will greet him.

'Rain, huh?' Rin thought when feel a few raindrops hit his head and shoulder, well, a brainless person also could tell that it going to rain soon as the sky already covered by gray clouds, but it won't mean anything to him even if it going to rain or not. His legs keep bring him toward where the crack supposed located, don't get him wrong, he is indeed bad at choosing a direction, but he can feel it, this weird feeling that he never feel before, it must be come from the crack and it give him an advantage since he could feel where this strange feeling come from, then he have no worry for being lost his direction. Both his hands already placed inside the pocket of his blue coat while his eyes only focus on the way ahead and his ears already picking any sounds he can heard, in case if something decide to suddenly ambush him, he will be prepared for a counter-attack. He should be close to the crack by now as he can feel the feeling get stronger and-

BANG

His head quickly jerked toward the direction where he heard that sound, because clearly only one thing in this world which makes a sound like that and used by an Exorcist. It was the sound of gunfire and whenever there is a gunfire, it's mean they attack something.

Oh Shit!

Without wasting anymore time, Rin put as much as necessary strength into his legs before he kicked the ground and create a small crater under his legs as the strength he use to push the ground cause him to launch himself toward where the sound of gunfire come from. He landed on the ground a few seconds later, but his momentum cause himself to be skidded on the ground for a few meters before his body finally stops moving right on the clearing. He also comes in time for seeing a man who he assumes one of ten Exorcists whch sent by Mephisto, being slammed toward the tree by... A girl?

Rin need to blink his eyes twice for making sure that what he sees is indeed a girl and... It was really a girl! The hell! Is this girl a Demon? Because she can swing that big cannon which attached on her left arm with ease as the cannon itself is really light. For a common Exorcist, they will think that this girl is indeed a Demon, but Rin is different, he is not a common Exorcist, but it only confuses him. Guess what? He can't feel any Demonic presence come from her. So, she not a Demon? Or maybe she able to hide her Demonic presence? But all this time, he never met a Demon who can hide their Demonic presence. Even that bastard clown can't hide his Demonic presence. So, if she isn't a Demon then what is she? He can think something like that's later, because right now, the girl already notices his presence.

He can feel his face warmed a bit, that because this girl outfit is... Rather revealing. She wears a short-sleeved black trench coat with a white zipper on the waist area and on tail of the coat, underneath the coat she wears nothing except... A string bikini and a short shorts with a white belt and a brown belt crisscrossing her waist and a black sleeve with white line on the center which stretched vertically, on both her arms, for the footwear she wear a pair of high heel boots which reach her knee. Her figure is rather short and he sure if not because of the boot she will look shorter now and her body also rather thin, which left him wonder how she can swing that cannon easily, she also have a black long hair which tied in uneven pigtail style (which he found rather interesting) and a cold blue eyes (with white pupil and a circular pattern around her pupil) which now staring coldly at him, like analyzing him. He knows he can't make any reckless decision, he needs to be calm or this girl will attack him (like what she does toward those nine people... Wait nine?) He doesn't have time to think about it anymore when the girl pointing her black cannon toward him with the barrel already shines, meaning it ready to shoot. But Rin remained stood in his place, there is no reason to be panicked, like what he said to himself earlier, he needs to be calm for dealing with this girl. The cannon shoots a blue orb which heading toward him in high speed, but Rin merely stepped aside and let the cannon fly past him and destroy the trees behind him. Look like the girl realizes that she can't defeated him easily like the others Exorcists when she narrowed her eyes and shoot more orbs toward him.

This time, Rin crouching down a little before putting as much as necessary strength into both his legs, before he jump in the air and success in dodging all the orbs. But the girl doesn't let him go that easy as she quickly lift her cannon and shoot more orbs which heading toward him who still in the air. But his momentum from earlier cause him to not stop in mid-air and thanks to his momentum too, he able to avoid all the orbs before landing behind the girl. The girl quickly spun herself in order to slam him with her cannon, but Rin react more quickly by kicking her cannon aside before lunged toward her and grabbed both her wrist and her cannon and tackling her toward the ground while placing his knee on her (exposed) stomach. He already sure that this girl isn't a Demon, but he still needs to do one thing in order to remove all of his doubt that she indeed isn't a Demon. He also knows that she does not possess a super human strength, because despite her struggling with all her strength to throw him from her, she still not successful in doing that. So Rin close his eyes and concentrating enough before opening his eyes again which now have a slit-pupil with red color while the iris already changes color from dark blue to bright blue, he shows her his Demonic eyes. Indeed, her eyes are widened a bit, but this also makes him sure that his assumption is right. She doesn't recognize him, any kind of Demons will instantly recognize who he is once they see his Demonic eyes, but this girl doesn't give him any response which close to recognition which mean... She 100% not a demon.

"I don't know what are you or why you are attacking my comrade, but calm down and I will let you go and we can talk about it" Rin said after closing his eyes and turn his Demonic eyes into his normal eyes and also hoping that the girl will cooperate with him. But looks like what he said to her only seem to make her more pissed as she narrowed her eyes before she does something that shocked him. From her left eyes, a blue flame bursts alive.

This very action making Rin dropped his guard for a few seconds, but it seem to be a wrong action as she quickly uses her legs to kick him from her and she quickly standing up before pointing her cannon at him again who manage to keep his balance. Look like there is no other choice, but to use the hard way. Rin quickly run aside to dodge the orbs which heading toward him, but what the girl does next is not something he expected. Because she quickly raises her cannon and a light appears around her cannon and then she slammed it again and he notices that her cannon already changed into a gatling gun. Rin know that dodging it by running would be useless as he can't run that fast, so there is only one way to solve this!

The barrel of her gatling gun starts to spin before it spin in high speed while launching numerous bullets toward Rin who only grab the hilt of his sword and narrowed his eyes as he planning his next move. Rin quickly draw his sword which causes a brilliant light of blue to appear and once again, Rin entered his Demon form. He can clearly see the girl's blue eyes widen a bit when the numerous bullet hit him, but doesn't hurt him at all. This all because once the bullets hit the blue flame which covered his entire body, the bullets will be burned and turn into nothing in a matter of second. He calmly stood there even if a storm of bullets are heading toward him, they all will stand no chance against his flame. But he decides, enough is enough and he doesn't want to waste anymore times. So in quick motion, Rin lunged toward her before slashing her gatling gun in half and stood in front of her with his sword pointed at her neck.

"Enough is enough, I don't have any intention to fight you and there is no reason for us to fight each other" Rin declared in a commanding tone because what he said isn't a statement, it was an order. He still can see the girl body still tense, probably because his sword is a few inches from her neck, so without hesitation he lowered his sword. The girl body seemed to calm down a bit and Rin consider it as a good time for talking to this girl, but...

BANG

Rin quickly grab the shoulder of the girl and quickly spinning their body so he was in front of her and what he predicted is right, he can feel a bullet hit the flame which covered his entire body before turning into nothing. He turned around and sees a man who he assumes the only unconscious Exorcist and right now, he is staring at him with wide eye. Well, he can understand why he staring at him with wide eyes because clearly, he was protecting the girl in purpose.

"Tell me, when you guys saw her did she attack you first or did it was you guys who attack her first?" Rin asks once again in a commanding tone. He is having his own assumption right now and he wants to know the truth as soon as possible.

"W-We... We attack her first because we thought she is a Demon" the Exorcist answered his question and Rin can't help but let out a sigh because his assumption is right proven from that man statement. From the way she fights, it clear to him that she attacks him because she thought he was one of them (which actually true) and thinks he wants to harm her like these people, so that's why she attacks him... Or that's was what he thought.

"Let's check on the others first and see what we can do (and hope they will be alright) and you..." He turned toward the girl who only tilted her head in response.

"Stay here" he commanded and it looks like she gives him one of those glares which say 'Get lost', Well, it not like he cares about it. Before he even able to turn around, the girl suddenly collapse and thanks to his quick reflex, he able to catch her before she fall toward the ground.

"Hey, what's wrong?" He asks and he can feel the girl have a hard time breathing. His ears then heard something and his head jerked toward where the sound coming and... That's it, it was the thing he looking for the entire time, the crack that the clown talking about... And how the hell he doesn't notice that it was there, the entire times?

The crack seems really unnatural as it appears on the air, but... It looks like already half-closed? No, it was closing to itself, maybe that was what causing this girl to suddenly collapse. Before Rin even know what he needs to do, the crack already disappears and it only makes the girl's condition become worse as she even starts to grip his coat for support. Rin gritted his teeth in frustration, he doesn't know what he needs to do and this girl doesn't look she can even breathe regularly, why he must care about her anyway?... No, it wasn't his nature to let another people suffer and he holds the rank 'Paladin' right now. He won't let anything bad happen to others... Even if that others mean a completely different being. And right now, he only has one solution.

"Hold on, I will do something" and after saying that's, Rin quickly scoop her up in his arms and carried her bridal-style and yelled to the last Exorcist for tried to check the others condition while he going to get help. After getting the positive response from the other Exorcist, Rin don't want to waste anymore times as he gathers enough strength on both his legs and start to dash toward where he comes from. What he does not noticed is the girl eyes which slightly open while staring at him in confusion.

SLAM

Mephisto's head quickly jerked toward his door when he heard someone open the door of his office with an unnecessary force, but what stood in his doorways is somewhat amused him, so, he will let it slide for now, just for now. Now back to the matter in the hands, so what kind of sight which Mephisto Pheles or known better by certain people as the second Demon King which control space and time, Samael, found amusing? Of course, the sight of The newly appointed Paladin, Rin Okumura who carried a mysterious girl clad in black who seem almost dying, in bridal style. He folded his hands in front of him in order to hide the grin which start to form in his face, this is going to be more interesting than what he thought. He about to open his mouth to greet the young man who wears the blue coat, but he shoots the purple haired man a glare that say 'Shut up or I will throw you out the window!', so he chooses to let out a silent chuckle.

Rin quickly entered the room and walk toward the center of the room, not even bothering to close the door behind him, his blue eyes solely focused on the purple haired man who seems enjoying this situation... Scratch that, he does enjoy this situation, after all seeing another person suffer is somewhat amuse to this clown and maybe one of his sources of entertainment. He narrowed his eyes when he notices the grin on the purple haired man's face which he tried to hide with folded his hands in front of his face, does see the mysterious girl in his arms who look really in pain, somewhat amused him? He sure of that, but right now, he has a bigger problem on his hands.

"Wipe that grin out of your face (he can't stand that grin!) and tell me anything you know about this girl and why she becomes like this after the crack dimension you mentioning disappearing?" He explained the situation concerning the situation of how he can be here with a girl clad in black in his arms and why she seems dying. He glance at the mysterious girl in his arms to see her expression and to confirm that if she indeed in pain. Her teeth are gritted together, one of her eyes is closed like she holds something and her other eyes open slightly revealing her oddly and beautiful blue eyes which now only staring at his face. She indeed in pain right now, but what cause the pain?

"I see, I see. Through your explanation and this girl's rather interesting appearance, I can assume that this girl is a being known as Other self which supposedly come from a dimension called Otherworld" Mephisto explained while gesturing the girl in the Paladin's arms who seems still in pain. He doesn't bother to cover his grin since the young man in front of him already found it and the grin on his face already turns into a smirk.

"I want the full explanation of Other self and Otherworld later, but right now, I want to know why this girl seems like dying and how to stop this" And what Rin said isn't a question, but an order from him. Being a Paladin must be forcing him to show his mature self more often and even revealing his leader persona which he never knows that he have it. The purple haired man only chuckle at Rin's order, but he quickly stops himself when he sees the young man's pupil slowly started to change color.

"Well, in order to answer your question, first you need to know what is an Other self and how they connected to this world" Mephisto said, but he prevent himself from rambling something nonsense like he planned when the Paladin in front of him shoot him another glare that said 'Just explain the damn thing before I lost my patience and turn you into Gehenna's ash'

"Other self is a being which resides in the world known as the Otherworld. The Other selves are a manifestation of an overwhelming emotion of a person and because the said emotion is so strong, it starts to manifest itself and taking a form. That's how the Other selves created and their connection to this world is that they hold the 'pain' of their creator or in other words their human-counterpart. The pain I mentioned before is an emotional pain, the very action of Other selves can be a reflection about what happened in Assiah. Example of two persons fighting for my affection (Rin almost vomit when he heard this) then their Other selves also fighting in the Otherworld, the outcome of this battle can reflect the result of the battle of affection. So the conclusion of my explanation is an Other self can't life by their own, they need another soul, because they are a being which created by an emotion, they don't have a complete soul, so I can said without connected their soul with other being's soul they won't able to survive this world and because the crack which connected our dimension with theirs are closed, so this girl also lost her connection with her human-counterpart" The Chancellor explained about what kind of being is an Other self and their connection toward this world, and Rin quickly able to grasp the solution of the problem he have right now.

"So, to make it simple, in order to make this girl stop dying... She needs to connect her soul into another person's soul?" Rin muttered before staring at the girl's face in his arms who still look hold a great amount of pain and look like the more time passed the more pain she will felt, because right now, her grip on his blue coat harder and even she closed both her eyes. He had no doubt that he needs to do something fast before this girl disappears from this world... But again, why the hell he needs to care about what will happen to this girl?

"Yes, but I will add something, the incomplete soul of an Other self can't connect itself with the soul of a Demon, after all, an Other self's soul is a part of human soul, so only a human soul that can really make a connection with an Other self's soul" Mephisto add and this make Rin narrowed his eyes at the grinning man. Does he do it in purpose? No, that's isn't important right now, the most important thing right now is to find a human and a way to connect this girl soul with-

"Of course, a half-human's soul also can make a connection with an Other self's soul"

Once the clown said this, Rin only staring at him with a bemused expression on his face before he narrowed his blue eyes. He swears if not because the role of this clown is important for both this school and the Order, he will personally burn him and turn him into Gehenna ash. Mephisto only let out a smirk when his green eyes notice that the eyes of the young Paladin staring intently at him, but those blue eyes quickly glancing downward when the girl in his arms gripped his coat harder than before.

"Since look like the lady in your arms doesn't have much times before she met her end, I will directly tell you how to connect your soul with her. It's very easy, all you need to do is kiss her and the process will happen naturally" Mephisto explained before a grin appears on his face when the 'Paladin' look like only half-listening to what he just said earlier. He couldn't wait for his response.

"Yeah, that's sound pretty easy, what I need to do is- Wait what?" Rin quickly turned his head toward the purple haired man who chuckling at his response. He let out a low growl to tell the man that it wasn't time for joking around.

"Please forgive me, but what I stated is the truth. To connect your soul with her, you really need to kiss her" Mephisto said while gesturing the girl in Rin's arms. Rin glaring at the clown for the last time before his focus all of his attention toward the girl in his arms. Does he really wants this? He means, connecting his soul with this girl, it isn't an easy decision and whatever he chooses will give a great effect on his future.

"Do you... Really want to live... Or die?" Rin's questioning. He knows that it was a stupid question and any sane people wouldn't even think to ask about things like that, but in this case, he was offering his soul toward an Other self, a being created by someone's emotion. So, it was clear as day that this girl belongs to someone else. But, if she really wants to live even if it means to share her soul with him. Then he won't mind at all. But with the amount of pain the girl experienced right now, he isn't too sure if she really can answer him.

"L... Li... Live" he heard a faint voice said that and quickly making sure that what he heard really come from the girl in his arms or no, but her expression really tells him that it is indeed her response. One of her eyes are opened slightly revealing her beautiful blue orb to him and even though he isn't so good in reading a person from their eyes, he can clearly see it on her eyes, it almost remind him of his own eyes when both eyes reflect one thing. The will and determination of staying alive and he would be damned if he doesn't do anything to help her. After give her a nod, he takes a deep breath before closing his eyes and quickly closing the distance between his lips and her lips and in a matter of seconds, both of their lips already pressed against each other. Her lips felt really soft and inviting against his lips and for a second, he almost forgets the reason about why the hell he kiss her in the first place. But what he can say? He was a fully grown boy complete with hormone and it was his first time kissing an opposite gender. Rin quickly opens his eyes when he feels something rushed into his mind, an images... Is it a vision? No... When he sees the images in his mind more clearly, he finally understands what is it... A memory... Memory of this girl... The memory of...

Black Rock Shooter.

A blue magic circle suddenly appear beneath him with both his body and the girl's body surrounded by blue light. He keeps seeing more and more images of her and what she had done in Other World and he finally understands what kind of person is her. All the lights which surround them suddenly disappear before the 'Paladin' fall to his knee and gasping for air, he can feel it, he can feel it now, part of his soul are missing, does it mean the process of connecting their soul, success?

The sound of clapping hands making him jerked toward the source of where the sound comes from before he narrowed his eye while still trying to catch his breath. Mephisto keeps clapping his hands with a big grin plastered on his face even though the 'Paladin' who still kneeling down already glaring at him.

"Amazing, congratulations for gaining your own Other self. With connecting your soul with her, now she officially become your own Other self" Mephisto said still clapping his hands. Rin about to reply his statement, but stop himself when he feels a tug on his collar. He glance at the girl in his arms and actually a little surprised to see her staring at him with confusing expression plus she also tilted her head slightly, it was really cute in a way. He shook his head slightly to clear his mind before staring at her.

"You can stand on your own?" Rin asks with concern filled his voice. At first the girl only staring at him with the same confusion expression before she gives him a tiny nod. After receiving a tiny nod from the girl, he gently put her down before helping her standing up. Look like the process of connecting their soul not only affect him, but her too.

"Well, I need to say that this connecting soul process really amazed me, but Rin, there will be one more trial for you. Once those Exorcists I sent a report this to the Order, the Grigori will question you about this. What will you do to when the time come?" Mephisto asks, when the blue 'Paladin' already turning around, close the door of his office which still open the whole time, pull the key and throw at Mephisto desk before pulling out another key from his pocket and insert it to the key hole.

"I will take care of that problem when the time comes as now this girl... Already become my responsibility" Rin answered without turning around and opening the door which so the sight of the dorm which already becomes his home for all this year he lives in True Cross Academy. He grabs the girl hand which seems still not fully understand about the situation around her before dragging toward the open door before close it when he already out of the purple haired man room who now already has a wide grin on his face.

"Thing will be become more interesting now"
