xXx

The ride was as uneventful as possible but once in a while Rin was positive some of the people inside the bus was glaring at her, like she was the dirt under their shoe.

But luckily she was quite used to it so the prickling feeling she always felt when she was sure somebody was looking at her was ignored.

More or less Rin was excited in the fieldtrip, this was actually the first time she got out out. Though she was quite nervous since Yukio wasn't by her side, she felt somewhat empty.

Watching the scenery outside the window Rin could hardly contain her grin and bounce at the balls of her feet, she was so excited!

Then she felt it, a paper ball bounced against her head and she quickly turned to glare at the person only to be pelted by more paper balls.

Angered Rin was about to snap to five of her grademates, three boys and two girls, when the teacher conveniently caught sight of the mess around her.

And with a look of dawning horror Rin realized that the teacher would jump to conclusions. She can't really blame her though, she was sure that she looked like a deer caught in headlights.

The teacher was fuming and Rin thought her nostrils flared in the most unattractive way possible.

"YOU!" The woman screeched and Rin thought she might've gone deaf for a second there.

"Yes?" Rin squeaked unsurely, she thought that maybe the teacher would be more careful blowing up. There were parents!

"You-" the woman started and a funny growling sound erupted from her throat, then she calmed herself down and glared at the blue-haired child. "-are probably the most horrid child I have met! Look at the mess you've done!"

Rin flinched not out of fear but because what she said was a blow to her self-esteem and a bitter feeling of resentment erupted from out of nowhere.

'There wasn't even that much of a mess!' Rin thought miserably and looked around her.

Oh!

Oh!

"Those good-for-nothi-" Rin muttered quietly not wanting the woman to hear the names she called those children.

Because apparently they just didn't throw paper balls at her, there were some chips here and there, some plastic wrappers and plastic bottles, and know she knew what the wet gooey thing was it was actually slime! And it just splattered at the window!

"What do you have to say for yourself!" The woman demanded shrilly. Not noticing the glances that were thrown their way by the parents on the bus and the snickering of the children.

Embarrassment flooding her system Rin blushed a red thick blush and squirmed uneasily at her seat.

"Well!?"

"I'm sorry." Rin answered without a stutter but it seemed to make the teacher more angry.

"Sorry!? Sorry!-" The banshee started screaming shrilly. "-Is that all you can say for yourself? Well, is it?!"

Rin winced at the sound and wondered why no adult or parent was standing up for her. Ignoring the irate woman for a while she listened on the conversations around the bus.

"-poor child-"

"Don't mind it. Don't you recognize her? It's the demon girl."

"Oh, is that so. Nevermind, then. Have you heard of the sale..."

Rin felt her throat became dry.

"What's the shouting at the back for?"

"Don't mind them, Driver-san. It was probably the demon again." A sneer.

"Really?" Doubt.

"Yes, there was this one time..."

Rin felt a prickle in her eyes. 'Nobody will ever believe me outside.' Rin thought bitterly and tried her hardest not to cry which she succeeded at.

She just redirected her attention once again to the teacher who was now sighing. Rin watched as she pinched the bridge of her nose.

"I wish it was your brother who was here, instead of you."

The last straw. Rin thought she heard a snap somewhere and she was about to let out all her frustrations, when it alll became a blank.

She couldn't hear anything.

Rin opened her eyes only to gaze at a dark abyss and a small wave of uncertainty went through her.

She was about to speak or maybe shout to the world what was going on but then a clown appeared.

Rin burst out laughing. She couldn't help it the man's clothes were ridiculous! Rin didn't notice it but she felt a lot better than before.

Though the man looked slightly miffed, to her much further amusement. But if you looked closer in the forest green eyes of the man, you can see the fondness and love in the green orbs.

He summoned a chair that resembled a throne and waited for Rin to regain her bearings.

Rin's laugh gradually became giggles and dissolved into small hiccups. She smiled at the man and apologized.

"I'm sorry, for laughing at you like that." She said with a bow though she couldn't stop herself from smiling.

The man just made a gestured of dismissal and summoned a smaller version of the chair he was seating on. He shrugged and decided to summon a table, tea, and biscuits as well. He had a feeling that this was going to take long.

Rin not knowing what to do, just stood there fidgeting slightly and thinking what to do if you don't know where you are.

Admittedly she was in an abyss, Rin was sure there was no book about this, pondering about it slightly she decided to ask Yukio if there are books about abysses.

Mephisto watched his sister (or half-sister, really but he wasn't really one for details) amusedly and quietly wondered why she isn't panicking, this wasn't a normal occurence after all.

He cleared his throat and smiled warmly at her. "Hello! Why don't you take a seat?" Mephisto gestured to the chair opposite to him.

Rin feeling no bad intentions from the man seated herself at the chair and watched as he poured tea for her and himself.

Mephisto's mind was going a mile a minute. He of course already had a plan on how he'll meet her sister, but now that he actually saw her his mind came up with a blank.

Admittedly, this wasn't on the plan but he was always good with improvisions. Though Mephisto has to wonder what happened actually to make his little sister almost summon her flames unconsciously.

Well, he had time.

Rin being not good with silence decided to break it with a question that has been bugging her ever since she saw the man.

"Who are you?" Rin asked curiously, blinking her blue eyes.

Mephisto stilled at the question weighing pros and cons whether he should tell his real name or not. He brought the cup of tea to his lips and sipped a small amount, still pondering on what he should do.

Deciding not to, Mephisto opened his mouth about to say his alias of somesort but he made a mistake. He looked into her little sister's eyes.

So naive, trusting, beautiful and and so blue. He can't see any imperfections in his little sister, to him she was perfect.

'This must be how Shiro feels-' Mephisto thought and mentally shook his head. '-I must be going soft.'

Though it was a problem seeing he can't lie to her, Mephisto was certain his Father would be having a laugh if he heard about this. Lying came easily to him.

Apparently, not this time.

He sighed knowing when he lost a fight and admitted to himself and only himself, that he most certainly loved his little sister.

Something that he wouldn't reveal to anybody else, even in the most dire situation.

"Samael, my name is Samael." Mephisto replied quietly but added almost jokingly with a wink. "But you can call me Mephisto-nii! Rin-chan!"

Rin ignoring the fact that somebody called her '-chan' furrowed her eyebrows in confusion and Mephisto was doing everything in his power to not hug his sister to death.

"Why would I call you '-nii'?" Rin asked thoroughly bewildered. 'Who would want a demon as his little sister?' She thought bitterly with sadness not so far of.

Mephisto blinked cursing himself inside his head and decided to tell the truth and everything, his sister deserves to know. Because he was sure that Shiro was already telling everything to her younger twin brother, Yukio, this was just fair in his mind.

"Now Rin I'm going to tell you something of great importance, okay?"

Rin hearing the seriousness of the man's tone listened and hanged on every word he was about to say.

Mephisto satisfied that his sister was nothing like her other brothers, on her Father's side of course, internally jumped in glee when Rin's attention was on him alone.

"Now, -" Mephisto began. "-I know that Shiro probably told you something terribly farfetched when you asked about your birth, correct?"

Rin thought about this for awhile and remembered one of the things her Dad told her about them coming from a watermelon, and frowned she knew he wasn't telling the truth (because a watermelon? Really?) but she also knew there must be a reason.

There were always reasons why adults didn't tell kids things, mostly for their own good.

But Rin just nodded which Mephisto took as a sign to continue.

"Truthfully, Shiro and I were the ones who found you with your mother. Now this isn't much of a problem but your heritage was one." The purpleheaded man confessed.

"My heritage?" Rin asked doubtful she wasn't one of those long-lost princesses or something, right?

"Yes, your heritage." Mephisto repeated solemnly and took a sip once more from his teacup.

"Though before we go there, do you believe in demons?" Mephisto inquired almost lazily.

He was surprised when Rin actually rolled her eyes. "You mean the evil that exists within people's heart? Because if it is Tou-san already told us about it, lot of times actually."

Mephisto blinked (he's been doing that a lot) once again and erupted in laughter. "Hahaha! Exists- in - people's- hearts-?" He repeated between bouts of laughter.

Rin not seeing what he was laughing at blinked owlishly and tilted her head like a puppy. Wondering what she did to offend somebody up there in Heaven that she'll be stuck with a clown.

A nice, amusing and truthful clown that's actually telling her everything she wanted to know but a clown nonetheless.

Wiping the tears that accumulated in the corners of his eyes Mephisto internally made notes to make use of everything his imouto-chan was saying for possible teasing material or maybe even blackmail material to the Paladin.

"Ah, I apologize I haven't laughed like that for a long time." Mephisto informed still feeling the need to laugh or snicker at the Paladin's words.

Rin pouted still not knowing what was so funny and Mephisto gleefully noted that he had seen that pout often in the face of the young Amaimon, now often known as The King of Earth, whilst he was the same age, in demon terms at least.

"Let's get back on track shall we? While those may exist, Rin, I'm talking about a different being." Mephisto spoke carefully making sure that the girl understood his words and seeing that she was indeed listening he decided to continue.

"You see, there exists two worlds Assiah and Gehenna. Assiah is where you were before I summoned you here, it's the human world so to speak. While Gehenna is the opposite, it's where demons live." Mephisto looked at his imouto seeing her disbelieving face he decided to change that.

He snapped his fingers and a small door appeared beside him roughly the size of Mephisto's hat if not smaller. The door opened to reveal a small figure with big ears and horns having golden eyes and wearing mitts and an apron around his waist.

"This is Ukobach." Mephisto revealed grandly and was pleased at the expression showing on the face of his imouto-chan.

His appearance surprise Rin but not in a bad way actually Rin thought he was adorable. She was in a complete state of amazement.

Setting Ukobach on the table Mephisto continued talking. "This is a demon."

Rin just looked surprised. "But he looks adorable!" She protested pointing a finger at Ukobach but quickly stopped remembering her manners.

"Yes, a demon's appearance may be like that-" Mephisto glanced at Ukobach. "-but don't be fooled. No matter what they look like there's a reason why they are demons."

Rin absorbed what she was hearing like a sponge, because this was by far more interesting than anything they have ever tried to teach in school.

Happy that Rin was believing him Mephisto mentally applause himself and sipped some tea and his sister suddenly piped up a question.

"Where are we then?"

Arching an eyebrow at Rin's direction, Mephisto couldn't help but applaud at his sister's demeanor and decided to answer.

"We are in neither." At Rin's confused expression Mephisto continued. "This is somewhere in the middle, so to say. Actually only I can open the path to this place. Even the King of Gehenna, Satan, cannot enter this place."

"How?" Rin asked ignoring the last part of what Mephisto said.

Here Mephisto grinned and set his cup of tea down. He snapped his fingers and the table and everything on it including Ukobach disappeared, only for clocks of various designs to appear behind him.

"I am the King of Time, Samael!" Mephisto exclaimed grandly and he could feel the thrum of pride inside of him when Rin looked at him in awe. Here he grinned once again and proclaimed. "I'm the one who rules time and space."

Rin took a deep breath and asked a question all the while dreading the answer. "Satan's real?"

Here a somber air covered Mephisto and answered the question with a simple. "Yes."

Rin can feel herself shaking and felt scared, it was one thing for demons to exist but for the King? She could barely think of what he can do but Rin knew one thing for sure, whatever he would do it wouldn't be good.

Rin felt Mephisto hug her and settled her on his lap.

"No worries Rin I wouldn't let him do anything to you."

And for that moment Rin believed him with her whole heart never doubting him.

Once she felt alright Rin shot Mephisto a sheepish smile conveying her emotions and Mephisto merely smiled in return.

Mephisto sighed gravely knowing that the next revelation would shock her sister, he set his chin on her head and hugged her tightly.

"You see Rin, you have demon blood running through your veins."

And all of a sudden Rin couldn't breath she felt complete and utterly cold even with the warmth that her Mephisto-nii was providing.

Because in the back of her mind, it all made sense. She could barely suppress her tears.

Because she's a demon! Everything, every name that she was called. It was true!

That was what tear her heart apart and she couldn't take it anymore she cried.

And Mephisto would've done anything, anything so that he didn't have to hear a heart wrenching sob from his sister. Knowing that right now she needed comfort Mephisto only hugged her tighter and promised to himself that his sister, Rin Okumura, wouldn't cry like that again.

"Rin whatever anybody says your blood doesn't dictate who you are." Mephisto muttered in Rin's ear. "You're the one who decides who you'll become."

"But! Everybody's right! I am a monster, I'm a demon girl!"

If this was in any other situation Mephisto would've snorted at the name because she was most certainly a demon girl but knowing that this was serious he fought the urge to snort.

But Mephisto suddenly narrowed his eyes a monster? His sister a monster? If those humans were calling this innocent girl a monster of all things then clearly they were the monsters.

He tucked this information in the corner of his mind and focused his attention on his imouto instead.

"Rin, you are not a monster." Mephisto said sternly removing his chin on her head, Mephisto looked at Rin's face fighting the urge to hunt those humans who called his sister a monster down and kill them in the most painful way.

"You hear me? You. Are. Not. A. Monster." Mephisto stated carefully not moving his eyes away from his sister's own orbs.

Already feeling the child's rising protest he shushed her and continued talking.

"You know, I'm a demon too. Am I a monster?"

Rin ceased her tears for a moment and looked at Mephisto's face clearly bewildered. "You are?" She mumbled quietly.

Mephisto didn't bat an eyelash. "Yes."

"But! But! You aren't like a monster at all!" Rin immediately protested. Sure he was wierd and a clown but he was probably as awesome and kind and nice as her Tou-chan!

If Mephisto were to hear that from anybody else he would've feel offended but knowing that Rin meant well he just chuckled.

"There are good and bad demons as well. Just like humans Rin. Not all of them are bad nor are all of them are good." Mephisto pointed out.

In that instance Rin understood completely. "So, it's just like that? Not all demons are bad?"

Mephisto just nodded and his face softened when he realized that Rin wasn't crying anymore.

"Was Kaa-chan a demon?" Rin mumbled nervously her palms sweating.

"No. It was your Blood Father."

"Oh." And in that instance Rin cared less, in her opinion she only had one father, one papa and that was a priest by the name of Shiro Fujimoto.

"He left us then." It wasn't a question but Mephisto nodded nonetheless.

"Kaa-chan's dead isn't she?" Rin questioned once again but this time she was thankful for the woman and Rin loves her too, because Rin knew that her Mom had a choice to give birth or not to. And she was grateful to her Mom even though her life sucks she still has important people in her life that she loves immensely.

Mephisto nodded once again and decided to tell who her real father was when she was ready.

"But what about Yukio? Is he one too?"

Mephisto shook his head and answered. "He isn't. Let's just say that the demon blood didn't run as strongly in him as it is in you."

Rin was just glad her brother didn't have to go through this and was content.

She caught sight of something shining on her Mephisto-nii's clothes and asked what it is.

"This?" Mephisto questioned amused and twirled his Exorcist's pin around his fingers. "It's an Exorcist pin. An exorcist is one who fights evil demons or something the like."

Here Rin's eyes sparkled. "Really? Then I want to become an exorcist!"

Still amused Mephisto asked why.

"Because I-I-" Rin faltered not really knowing what brought her to say that but then she remembered her family, her dad, her brother even the clergymen and she continued on determined. "I want to protect the people close to me from demons."

Mephisto was actually having a hard time not laughing because who would've thought that the daughter of the King of Gehenna be an exorcist? He could barely suppress his gleeful laughter.

But outside Mephisto just smiled at his sister and ruffled her hair ignoring her protests.

XxX

"Are you sure? I could take you home you know." Mephisto asked worriedly because this was his sister damn it!

"I'm fine." Rin rolled her eyes at her Mephisto-nii's mothering. But still she was happy that other than her dad and younger brother somebody cares about her.

But still she couldn't believe the power that he has. Gazing at the inside of the bus Rin saw nothing moving like their movements were paused and the teacher was in the exact same position as when Mephisto summoned her.

Mephisto just looked at his work smugly and can't stop the thrum of pride that went through him when his sister was in awe of his work.

Still he couldn't help but think that he forgot something important.

"See you later?" Rin questioned nervously but brightened up when a smile was sent her way.

And just like that she returned to her spot on where the woman was scolding her and Mephisto went his way still trying to remember what he forgot and bid farewell.

Then everything started moving again the teacher was screeching again but Rin felt better knowing that she was different. And she'll prove it if needed.

XxX

Somewhere in True Cross Academy Mephisto remembered what he forgot and resisted banging his head on his desk.

I was supposed to ask what made her summon her flames unconsciously!

xXx

Yeah... Hope you liked it. And I've always liked a brotherly!Mephisto especially since Rin is a girl here. In my opinion Mephisto would probably involve himself more when he has a sister and probably his only sister.

Sorry if he's out of character.

Bad? Good?

Review!
