Hello! ManyJinxes here! I love Ao no Exorcist and wanted to make a Fem!Rin story so here it is! I apologize if there are some Oocness.

Yeah.

XxX

In class 1-B a six-year-old girl was looking apathetically at the window and completely disregarding what her sensei was teaching, while on class 1-A her twin brother was probably soaking everything his sensei was talking about like a sponge.

At first glance nobody will ever think that they're twins. Nevermind the first glance, one wouldn't think they were related at all. One was physically strong and had an indomitable will and the other was frail and weak willed, some would point out that they weren't alike at all.

But they both care deeply for each other and love each other unconditionally, especially when the younger one was getting bullied his sister wouldn't need to think twice about interfering.

"Okumura Rin!" The teacher yelled. All of the teachers has an immense dislike to the elder sister and they enjoy on calling her out on her mistakes, no matter how cruel it might be she never complains which was probably one of the reasons they never stop.

"Are you even listening!?" The teacher quipped with a mocking sigh and was pleased with herself when she heard the snickers and giggles of the class.

Okumura Rin. Was an enigma to say the least, she doesn't care about taunts even if you degrade her she wouldn't even bat an eyelash but when her brother and her family's involved you better wish that you already have a reservation in the hospital because nothing, NOTHING can make her stop from beating you UP.

Okumura Yukio was the girl's younger brother. He was a soft-spoken and adorable child, some might say that he was a teacher's pet but no one could help not liking the child. Every adult and teacher alike want to protect the child even from his sister if needed to.

One might put it like this, that the younger brother was an angel and the elder sister was the devil.

But some forget that...

...

...

Good cannot exist without Evil. Darkness cannot exist without Light.

«.XxxxxX.»

Few weeks later...

"But! Yukio, the only reason I'm going is you!" exclaimed a pale adorable six-year-old with long navy blue hair. She was small, smaller than her brother even, but it only adds to her charm. And underneath her adorable exterior was a very strong girl that can lift things twice her size.

She was wearing a skirt since her brother and Dad convinced her that a Field trip, of all things, should be something that you should prepare for and dress with your best clothing.

But, she can't see the point in wearing a skirt when it makes it hard to move and kick people's butts and the only reason she's wearing one right now is because she managed to settle on a compromise.

And that was under condition that she would wear spandex shorts underneath.

She was currently wearing a black ruffled skirt and a white long sleeve button-up blouse and a black ribbon was tied around it's collar. She had a pair of black converse. Her long navy blue hair was on pigtails with black ribbons holding it.

Her younger twin brother was currently in bed, because of a flu on the exact same day of their field trip. They even managed to talk the teacher on letting them stay together in the same bus!

All for nothing.

"Nee-san I want you to go and have fun, Ne?" The brunette boy said in a soft tone.

"It won't be fun without you." Rin mumbled with a pout and was playing with the hem of her skirt.

Flash!

"Rin-chan is so adorable~!" A man with the clothing of a priest said all the while taking pictures with his camera.

The man had glasses with the chain adorned with beads and a cross. He had red eyes and light gray hair.

Ignoring the glare that was sent his way, Father Fujimoto kept taking pictures of his beloved twins.

But, unfortunately...

"-ice! Good pose! Keep it up! Adora- GAH! What was that kick for Rin-chan!?"

Rin hates getting photographed...

"OUCH! Don't step on my toes!"

And being called '-chan'.

.XxxX.

"Papa? Will Yukio be alright?" Rin asked looking beside her to see her Dad and tilting her head like a puppy.

Shiro Fujimoto, The first and only Paladin, Meister of all five categories; Knight, Aria, Tamer, Dragoon and Doctor. Most importantly Adoptive Father of both Yukio and Rin, the children of Satan.

... was squealing 'manly' squeals in his mind when Rin called him Papa.

On the outside, he was wearing a small smile.

"Don't worry, Rin-ch..." Covering his mouth a chill went down his spine when he felt a glare.

"What was that otou-san?"

Ignoring the sudden change of calling, Shiro coolly ignored the sudden fear that appeared in the depths of his mind.

"No, no it was nothing." He said worriedly while idly scratching his cheek and for protective measures he moved away from the freakishly strong girl.

Shiro looked at his little girl, and a bashful smile made a way to his face.

"Yukio's strong, who do you think his sister is? He won't be beaten by a measly flu."

Rin stopped walking and faced her Dad. She gave him the biggest grin she could muster.

"Yeah!"

Shiro gave his own grin in return and patted Rin's head with affection.

"Well then, let's go wouldn't want to be late, do we?" Shiro asked with a smile and withdrew his hand from Rin's head.

"Yup!" Rin chirped and began walking side by side with her father wearing a smile that can rival the sun.

Rin-chan's so adorable~! Too bad I can't go with her... Shiro thought glumly and thought back on what happened this morning.

Flashback

Loud stomping can be heard around the monestary, and Shiro guessed that it was the sound of somebody running.

"Who's running around?" Asked Shiro to one of clergymen.

"We don't kno-"

BAM!

"PAPA!"

"Rin! What happened?!" Shiro asked worriedly and was fussing over Rin endlessly, looking like a blur.

Rin looked afraid. And Shiro swore that that was one of the few times that he'd seen Rin scared.

Her blue eyes were glassy and a heart breaking sob escaped her lips, which Shiro was sure that she tried to stop.

And that was one of the few times Shiro Fujimoto felt so much negativity in himself.

Anger, for the person or thing that eved dared to hurt his daughter. Pain, because -damn it!- his daughter was crying! And mostly disappointment in himself, because he was her father. And fathers were supposed to protect their children.

Shiro can only blame himself for the face that Rin was showing.

And promised to himself that he would prevent that expression appearing on Rin's face again.

"Yu-Yu-ki-io..." Rin said in between sobs and Father Fujimoto quickly carried Rin to their bedroom, ignoring the squaking sound that Rin made between her protests on 'being carried like a baby'.

Father Fujimoto felt his lips twitch upward, even while crying she still has that fire that she inherited from her mother and Shiro knew that if they weren't in this situation he would've been full blown laughing.

When they arrived at the twin's bedroom Shiro quickly went at the younger boy's side. Yukio was still in bed but, frankly, he looked horrible.

He was sickly pale, and Father Fujimoto was sure that he has a runny nose. Shiro noticed a bucket by his side and judging by the smell, Yukio was vomiting, He looked at the trash bin in their room and noticed that it was near Yukio's bed and it was full of tissue paper.

Noticing the thermometer at their bedside table and the wet towel on Yukio's forehead, Shiro concluded that he must have a high enough temperature that was most probably the cause of Rin's fear.

Shiro moved the wet towel from Yukio's forehead and touched his forehead.

Only to jerk his hand away from the boiling hot forehead of his son. Shiro thought that he saw burn marks on his hand and quickly hid them from Rin's eyes.

A quiet cough was heard from the sick boy and Rin quickly moved her eyes to the brunette boy. Of course, not without throwing an inquiring glance at her father's figure and more specifically his hands.

At times Fujimoto Shiro can't help but think of Rin's high observational analysis as a curse and a blessing of somesort.

"Nee-chan?" a quite soft voice was heard from the sick boy. Rin quickly appeared at his line of sight and grasped the hand of her younger twin, even if she might have some burns later on.

"What is it Yukio?"

"... I'm sorry." came Yukio's soft reply. Rin cocked her head in confusion while throwing a questioning glance at her Dad.

He was confused too.

And as if sensing the two's confusion Yukio quirked one edge of his lip. The situation would've been humorous, if not for that one little action brought a coughing fit to the younger child's body.

"Yukio! Don't force yourself! You can apologize when your all in tip-top shape!" Rin proclaimed while holding her younger twin brother's hand on her own and graced him with a small soft smile. Yukio couldn't help it, he blushed from the sight.

Father Fujimoto smiled at the twins and ruffled their hair. They were all wearing smiles and grins, happy about spending time together.

Yukio glanced at a clock and luckily it was near him so he didn't need to move much, he promptly panicked.

"Nee-chan! What are you still doing here! Your supposed to be in school already, for the field trip remember!" Rin looked surprised at her brother's panicking figure and before she knew it, her Papa already slung her on one of his shoulders and he kept screaming about clothes that would absolutely look adorable on her.

A chill went down her spine.

"Noooooo!" A moan was heard through out the monestary and the clergymen prayed for the soul that cried out such an anguished moan.

Flashback End

That was what happened a few moments ago. Now Fujimoto with Rin in tow were at The Twins' Primary School, ready to head out using the bus.

Rin was standing alone beside a bus with the doors open, her Papa talking to one of the teachers most probably asking the teachers to take care of her.

Rin elegantly snorted at the thought, her teachers going to take care of her?

They're more likely to cut their own fingers one by one.

The adorable girl shook her head to get rid of the bad thoughts and silently grimaced. She was positive that this Field trip would be terrible, with the capital 'T'.

...

After talking to the teachers Fujimoto Shiro couldn't help but silently fume about the way they talked about his daughter. Shiro just can't understand why people hate Rin and not Yukio by extension, but he was willing to bet it was because of her bloodfather's genes that manifested more on her than Yukio.

But needless to say those people were horrid and he was willing to bet that they wouldn't even care if she gets lost out there in Kyoto.

He sighed for the nth time and ran his hand across his hair, hopefully Rin wouldn't get in much trouble.

Because trouble just happens to like to look for her like a bloodhound.

...

Rin Okumura was nervous, though she would deny this vehemently later. This was actually the first time that she would be away from Yukio and her Papa for more than a few hours, she can't help but feel unnerved.

She kept shifting her weight and nervously fidgeted at her standing place, that was until somebody lifted her from behind.

"Kyaa!"

Rin blushed tomato red whether because of the shout (because Rin would undoubtly break his bones if he ever suggested it was a squeal) or suddenly being lifted behind, Shiro didn't know and promptly hugged her tightly.

"I'm gonna miss you, Rin." He breathed softly and watch as her panicked face melted into one of fury and once again changed into a serene one but she couldn't hide the nervousness from her Papa who raised her.

"I'm gonna miss you too, Papa." She replied softly and hugged him back tightly. "Don't get into too much trouble when I'm gone!" Rin added playfully.

Shiro had to snort at that and ruffled her hair. "Please, half of those were caused by you."

"And the other half?" She asked using a smug tone happy that they were bantering normally and just enjoyed her Papa's presence to the fullest, already missing Yukio terribly.

Rin laughed at the scowl and halfhearted glare her Papa sent her and happy that he set her down on the ground, once more.

"Just take care of yourself out there kiddo. You can never be too careful." Shiro said seriously looking directly at her daughter's magnificent blue, blue eyes.

Rin shot her Dad a look but nonetheless nodded obediently and repeated the same thing too her Dad earning again another hair ruffle.

One of the teachers was waiting impatiently for the seven year old girl and kept shooting dark looks at the father and daughter pair which they ignored.

Rin noticed the time and smiled softly. "Well, I guess it's time for me to go..."

"We'll all miss you Rin." And with one last grin Shiro hugged his daughter and mumbled.

".. The two of you are growing so fast."

Rin grinned at the mumur of her Dad and couldn't help but reply.

"That means you're getting old too, Old Man!"

Father Fujimoto mocked glared at her and made shooing motions, Rin was about to board the bus but stopped momentarily and turned her head to look at him.

"Oh and Dad, the only reason I'm strong is because you raised me." Flashing him an embarrassed and shy grin the girl quickly boarded the bus, missing the smile full of love and pride her Dad was showing the world.

'Here goes nothing..' Thought Rin nervously and sat quietly at a seat that was supposed to be for two people.

...

Shiro waited for a while and only started to leave when the bus was already out of sight. He stiffened momentarily and was about to attack when a dog appeared.

A dog wearing a large pink ribbon of all things with white polka dots, he didn't need to check the Exorcist trinket to know that this dog was an Exorcist. Though that doesn't stop him from thinking that his choice of clothing was 'unique' for lack of a better word.

He already saw him for a few times in this form and seeing him like this always leads to a snort of laughter.

"Ahh, Mephisto what brings you here?" Shiro questioned curiously and pocketed his hands.

The dog just looked at Shiro oddly with an almost raised eyebrow, like he couldn't believe this man was talking to a dog in broad daylight.

This led the priest to snort again and silently murmured. "I already checked our surroundings earlier, Mephisto. No need to keep yourself in that form."

The dog huffed like he was mildly offended and didn't like the way the priest said 'form'. The dog seemingly thinks this form is adorable, thank you very much.

Just to make sure the dog looked around carefully to see if what the man said was true and in an explosion of white smoke and some various confetti a man appeared in place of the dog.

The man if you could even call him that had clothes that would make you think of a clown. He had white jester-style pants with matching maroon pointed shoes and a white suit-shirt and undershirt with a cravat of the color pink and white polka dots, a white top hat also sat on his head with purple and pink around the base over a red lace and matching purple gloves. He was also wearing a cape worthy of Dracula only it was white in color with a violet underbelly, if that wasn't odd enough he had dark purple hair and the oddest forest green eyes.

Needless to say you would expect a carnival around somewhere when you see him.

Father Fujimoto didn't react at all and settled on staring on the horizon where the bus his daughter was riding has gone.

Shiro just sighed resignedly and quietly accepted the fact that since becoming an Exorcist no moment of his life has ever been normal.

Well, normal was overrated.

And there's also the fact that he was raising the children of Satan, one of them even having blue flames.

Which was currently sealed into a sword, named 'Kurikara'. Conveniently enough when Rin's flame was sealed into it, so did most demonic qualities that was supposed to have manifested when she was younger. And the Paladin would bet that if they didn't seal her powers back then she woud've been a lot, lot stronger, his daughter was already as scary enough as it is and just imaginig her getting back her real strength always brought a wince coupled with cold sweat.

The man was apparently quite irritated by the fact that the priest was ignoring him, so he decided to answer Shiro's earlier question.

"What? I couldn't visit my fellow Exorcist?" The man called 'Mephisto' said and then he suddenly donned a smirk when he heard a snort of laughter beside him.

But Mephisto quickly went to business, which concerned a certain twin that was under the care of the Paladin.

"He can see demons." There was no question in the green haired man's tone, it was just like he was stating a fact. Shiro frowned at this and sighed.

"What are you going to do with him?"

"Me? I think you have it all wrong, Shiro. It's 'What are you going to do?'." Mephisto smirked and continued his tirade. "I do not have any influence to your son, only you can decide what's better for him."

A laugh erupted from him. "Though I wonder what's the wiser choice? Letting him think he's only seeing things or let him actually be an exorcist?" Mephisto tapped his chin seemingly thinking about it.

A wicked gleam appeared in his forest green eyes and an amused smile can be seen on his lips.

"This will be interesting."

Shiro not knowing what to say after all that moved to another topic.

"So why are you really here?" The Paladin questioned not believing that the man was here for that reason.

An exasperated sigh escaped the greenhead's lips.

"That hurts Shiro-chan-" Here a tick mark appeared at Shiro-chan's temple. "-why can't you just believe me?" Mephisto was wearing a dejected and hurt face saying all this.

But then a sinister smirk appeared at his face when Shiro was about to bump his head.

"But if you must know I simply wanted to know if my little sister was doing well."

Shiro stopped breathing halfway and Mephisto quickly disappeared leaving a bewildered, disturbed and utterly stupefied Paladin behind.

"WHAT!? MEPHISTO GET BACK HERE! WHAT THE HELL WERE YOU TALKING ABOUT! MEPHISTOOOOOOOOOOO!"

Bad? Bad? Good?
