Your name is (Name) Yeager, your Eren's little sister, a year of gap, the difference is that you have brown eyes not green like his, but have brown hair like him. Though you are Eren's sister you don't have any friends, is not that your shy or anything, is that Eren is an overprotective brother, and you hated it.

There you were walking all cutely and saw Jean.

"Hi hi Jean" you said while waving your hand and walk towards him

He flinched a little, you are pretty, and your the first girl who actually talk to him without getting disgusted or annoyed "hey (name)"

"How are ya?!"

"Hmm fine I guess"

You giggled a little

"And you?"

You sigh "well, I'm still dealing the whole 'over protective Nii-san" (Nii-san means big brother in Japanese)

"Ahh yes Eren, I'm surprise he's not here"

You sigh again "I was able to ditch him, thank goodness Heichou gave him stable-duty"

Jean puts a hand on your shoulder "well you're lu-"

"GET YOUR FILTHY HANDS OFF MY SISTER!!!!"

You and Jean look at an angry Eren, who was running towards you and Jean.

Everything happens so fast you didn't notice that Eren grabbed Jean by the shirt and so did Jean with Eren. They were about to punch each other

"HEY!!" They both look at you and you were really angry

"Nii-san what the hell, I was just talking to Jean"

Eren releases Jean and looked at you

"Were just talking to him?"

"Yes"

"Then why the hell was his hand on you?"

You got annoyed

"It's called 'been concerned' dumb-ass"

Eren grabs Jean by the collar "say it again Horse-Face, I dare you"

Jean dose the same action to him "your a dumb-ass"

And with that they both started to fight

"Hey guys- gu-"

You took a deep breath

"WILL YOU TWO STOP IT, YOUR ACTING LIKE CHILDREN"

"You took the damn words right out of my mouth"

You flinched and the boys stopped fighting

You turn around and saw Corporal Levi

"Sir!" You three saluted

"Yeager, Kirstein, stable duty for two weeks, starting now "

Jean left but you and Eren stayed there, cause well you both are Yeager.

"Umm, sir witch one of us is at stable duty" said Eren

"Obviously the one who was fighting idiot" said Levi harshly

Eren saluted and left

You did the same but something caught your wrist, you turn your face and saw Levi

"Did I say you were dismiss"

You shacked your head and faces him completely

"Shitty Glasses wants you at her lab"

You nodded then realize that Levi didn't let go of you wrist and blushed a little, you have a crush on him, of course no one knows, not even Eren, hell if he's overprotective by you having a friend, he's totally going to freak at the fact that you like someone.

"Come on" he said while dragging you at the hallway to Hanji's lab

~~~~~~~~~Time Skip~~~~~~~~~~~

You enter at Hanji's lab

"Here she is Shitty Glasses"

Hanji looks at you "good, (name) come don't be shy"

You walk towards her and sat at a chair in front of her

"Would you mind if I make a experiment on you" you shacked your head

"no I don't mind, well, it depends, it's has nothing to do with being a Titan shifter, right?" (Your Eren's sister, so your a Titan shifter too XD)

"No sweetie"

"You better not kill her Shitty Glasses"

"Oh come on Shorty, I'm not capable on killing the most cutest thing in world" she said while squashing your cheeks

"Ow, your hurting my cheeks"

"Sorry"

"So what's the experiment?"

"Drink this" she gave you a blueish liquid

"Are you sure it's safe?" She nodded at you, and you drank it

"Do you feel different?"

"Not rea- ow" you put your hand on you head "my head hurts"

"Look at what you did Shitty Glasses" Levi got closer to you, you got up but fail and sat back down before you could fall

"Can you get up" still holding your head with your hand you shacked your head

"No I feel kinda dizzy"

Levi tch'ed and picked you up bride style

While walking to go to your room Eren runs towards Levi

"Sir I- what happens to (name)??"

"Shitty Glasses experimented something on her"

"Oh, will she be alright??"

"How the fuck would I know, ask Shitty Glasses"

Eren nodes and was about to leave

"Yeager did you finish cleaning?"

"Yes sir"

Levi nodes and keep walking, he looks at you, tch he said

Finally Levi reached your room, kicks the door open and walks inside, puts you gently on your bed.

Levi looks at you one more time moves your brown locks from your face and study your face 'tch be alright brat' and he left

~~~~~~~~Next Morning~~~~~~~~

You groan "Ugh, what the hell?" You got off your bed and wheat to the bathroom

You look at yourself at the mirror then down but look up again with wide eyes 'The Fuck' you look carefully and closely and saw two brown cat ears, then look behind you and saw a fluffy brown tail.

You started to freak out and storm your way to Hanji's lab

~~~~~~~~~~~~~~~~Mini Time Skip to Hanji's lab~~~~~~~~~~~~~~~~~

"HANJIIIIIIIIII WHAT THE HELL DID YOU DO TO MEEE!?!?!?" You kicked her door open

She looks at you "ah you alright thank goodness"

"Alright?!?!" You got closer to her

"You turn me into a cat"

"Actually half cat, you only have the ears and tail"

"I don't give a damn, what will I do?"

"What will you do? What do you mean?"

You look at her "there's no way in hell that I'm going out side and everyone will see my cat ears and tail"

She took your cat ears and start it to touch them "aww but you look so cute" you purr a little but then covered your mouth

"Come on, if it makes you comfortable, sit next to me at the mess hall " said Hanji with a smile

You sigh "fine"

You and Hanji made your way to the mess hall. And so you sat next to Hanji

They all looks at you, you felt a bit uncomfortable, finally someone breaks the silence

"So are they real cat ears?" You look up and saw Petra looking at you with a sweet smile

You nodded "one of Hanji's experiments"

"So Cadet Yeager your feeling alright?" You turn your head and saw Levi, you blushed a little at the fact that he was caring, right?

"Yes Heichou, althought I would like to know when will I be return to normal" at the last sentence you look at Hanji and she chocked a little

"Ha, well, you see, umm, I'll have to make an antidote that it might take weeks or month, or even-"

"Don't say years, or I'll kill you" you gave her a death glare, that literally scared everyone, well excepted Levi.

"Eh!! You wouldn't kill me?! Would you?"

You look at her strait in the eyes "are you daring me" then you took your hand and was about to bite your thumb to turn into a Titan (a Titan with cat ears and a tail, can you imagine that XD)

Everyone jumped and Levi hold your hand, then something unexpected happened, you started laughing

"Ahahaha you-you guys think th-that I'm stupid enough to-to turn myself into a Titan in here ahahahahahahahaha man I got you guys good"

They all were staring at you, Levi let go of your hand and Hanji got closer to you

"S-so your not going to kill me"

Then you relax a little "haha no, but seriously you better make an antidote"

Hanji relaxed and sigh "who knew a cute little girl like you sure can give someone a heart attack"

You giggled

"(Name)!!"

You turn around and saw Eren

"hi hi Nii-san-" you were cut off by Erens hug, he back up and started to touch your face to find any injury

"Are you alright? Your not hurt?"

He puts his hands on your shoulder "what the hell happened to you?" Of course referring to your cat ears and tail

You look at him and then at everyone else "one of Hanji's experiment"

He looks at Hanji

"Please next time don't do any experiments on her" Hanji nodded

You backed up "will you stop it Nii-san, I'm not five, I'm seventeen for crying out loud, I'm not going to die no matter what happens to me"

"Well actually if we cut off your weak spot-"

"Not now Hanji" you said, this time you were really mad, for reals

Eren look at you "is that, I-"

"You what, I know you mean well, but please let me be, let me have friends, let me do what ever I want, without you overprotecting me"

There was a dead silent at the mess hall

"Mom told me to protect you" Eren said and got closer

*Flash Back*

You saw your mother underneath the broken house you, Eren, and Mikasa tried to safe her but she told you three to leave "BE SAFE, STAY ALIVE"

"MOM NO!!" You screamed

Your mom was at the Titan's grip

"EREN PROTECT (NAME) NO MATER WHAT!!" And with that you saw your mother getting eaten.

*End of Flash Back*

Your eyes watered at the thought if your mother

You pushed Eren "I THOUGHT I TOLD YOU TO NEVER MENTION HER!!"

Levi got between you and Eren "stop" he looks at Eren "Yeager stable duty for another week" then he look at you "and Cadet Yeager go to training"

And with that he left.

You looked around to see who to have hand in hand combat practice, to be honest you wanted to get rid off your anger you had towards Eren

"Hey beautiful" you look up and see a tall blond hair guy, Reiner

"Oh hey Reiner"

"Need a partner?"

You nodded "but not just any partner, I need someone strong"

"Oh, so you can put all the anger you have with your brother"

Your eyes were wide and your cat ear twitched and look at him "how do you know that?"

He raise and eyebrow "really? You just had an argument with him at the mess hall, everyone knows"

You look down "oh great"

He pated your head and chuckled "don't worry Kitten"

You gave him a dead glare "don't call me Kitten, just because I have cat ears and a cat tail doesn't make me a cat"

He chuckled "whatever you say"

Then you started fighting. You threw a few punches but he dogged everyone of them, well excepted for one, he grabbed his cheek

"Damn you really put your anger at that punch"

You giggled then you threw a kick but he caught your leg

"Wow, that was a close one beautiful"

He let go of your leg "my turn"

He did the same, threw a few punches but you dogged them easily, he threw a kick, you got down to doge the kick and kick his leg causing him to fall

"Ooof!!" You put your foot in his chest

"You were going easy on me weren't you?"

He shakes his head "not in your wildest dreams Beautiful"

You giggled, you gave him a hand to help him get up

"Thanks Reiner"

He chuckled "no need, anytime"

"Cadet Yeager, Braun"

Your ear twitched knowing who the voice belong to, turn around and saluted "sir!"

Levi waved his hand to dismiss your salute

"Quite a combat, Braun go to the infirmary to take care of you wounded cheek"

You look and Reiner and saw his cheek swollen

"Oh my gosh, Reiner I'm so sorry" your cat ears were down and so did your tail, showing that you were sad

"It's alright" he turn to Levi "thanks sir"

Levi nodded and Reiner left

"Quite a punch you gave him"

You look down avoiding to look at him

"Come with me"

So you followed him, and you enter to his office.

"Clean my office"

"Umm, why exactly Heichou?"

Levi got closer to your face

"You dare to question your superior brat?"

You look down and started to play a little with your tail

"No, is that, well, I don't see the reason"

He pull your chin up

"A reason?, there are to many reasons"

You look to the side "first, you made your little joke scaring the shit out of your superiors and comrades, second, your argument with Yeager drying yourself attention, and third"

You yelp then looked at him, he was holding your tail "your stoking my face with your tail"

Your eyes wide, and grabbed your tail "Heichou I'm so sorry"

He back up "get the cleaning supplies, you have two weeks of cleaning duty brat, in my office"

You nodded and went to get the cleaning supplies

'Damn brat' he thought touching his face where you were stroking him 'her tail is soft and fluffy' he smirk at that thought 'stop it Levi, don't be a pervert'

You enter with the supplies, your tail was wiggling to the sides. You turn and bend to put the supplies at the floor and Levi got closer to you 'tch, how distracting' you didn't notice, but felt someone stroking your tail. You turn and saw Levi stroking your tail and you blush

"You better hide your tail when your cleaning here brat, it's distracting"

You blush even more "o-ok Heichou"

You took your tail, lifted your shirt a little and hide your tail

"There, is that better?"

He nodes and went to his desk "now clean the windows brat"

You nodded and do what he said, it was now turn to clean the highest part of the window, even though Eren is tall, sadly your not going to be as tall as he is, your quite short, almost the same height as the Corporal, two centimeters short.

"Umm H-Heichou?"

He hummed in respond

"Can a get a chair or a ladder?"

He looks at you "why?"

"Well, I can't actually reach, sooo-"

He sigh and got up and went to your direction

"Pick up the cloth"

You picked it up

"Dip it in the bucket of water"

"Um, sir I know how to-"

"Dip it. In the bucket. Of water" he repeat it

And so you did, still having no idea why was he saying all of this

Without warning you were lifted, you freaked cause you didn't like it when people did that. You balanced yourself by putting the palm of your hand at the window

"H-Heichou!!"

"Shut the fuck up and clean the damn window"

You clean the windows without any problem

When you heard a knock on the door

Still on Levi shoulders "name and business"

"Uh Cadet Eren Yeager sir, I wish to inform you something"

"Come in"

Eren enters "sir I-"

He was staring at you and Levi with wide eyes

Levi turn around, you managed to balanced yourself and was still on his shoulders and he looked strait at Eren

"You what brat"

"Um I-I finished doing my cleaning"

"Good"

"Um sir if you don't mind me asking, why is (name) on your shoulder?"

He tch, and you blushed

"I'm at cleaning duties Eren, I couldn't reach the highest part of the windows" you said trying to sound firm, but you couldn't

"Oh, umm, ok, I guess" he got a little worried, you've never actually call him Eren,

"Is that all Yeager?"

"Um, yes sir"

"Then you are dismiss"

Eren nodded and left

"Did you finished cleaning the windows brat?"

"Yes Heichou"

Levi dropped you on the ground

"Ow!" You said while rubbing your butt

He only tch'ed and sat at the couch

"Bring me a cup of tea"

You got up "pff, whatever" you whispered, but unfortunately Levi heard it "what did you say"

"Nothing!!" Said and ran to get his cup of tea

"Tch, troublesome"

You came back with his cup of tea

"Here you are Heichou"

He took the cup, while taking a sip he patted the side of the couch, telling you to sit. So you did, and without warning Levi started to pet you behind your cat ear.

"Purr-" you gasp and covered your mouth, Levi raise an eyebrow and looks at you

"Did you just purred?"

You shakes you head as a 'no'

Levi pets you again

"Purr meow-" you covered once again your mouth and got up, you started to blush madly, Levi got up and whispers huskily at your ear

"You like it don't you?"

You shake your head

"Oh really?"

You node

Levi, a dare devil he is, grabs your tail, you gasp at the sudden movement he did

"You can't lie to me"

You dare yourself to look at him and saw of a bit of amusement in his eyes

"I-I'm not lying to you"

"Then why did you hesitated"

You look away try to walk away but Levi had his grip on your tail

"I-I didn't h-hesitated"

Levi let go of your tail and wrap his arms around your waist and pulls you on his lap, you yelp at the sudden movement, but you still avoid to look at him

"Look at me"

You shake your head

He grabs your chin you face him now but your eyes didn't meet his

"I said look at me"

You shake your head again

"Why not?"

"B-Because then I'll do something t-that I might regret"

Levi grab your tail and squeeze it, you put your hands on his shoulder and hiss a little

"Look. At. Me"

'Is now or never' you thought

Finally you look at him strait in the eyes

"There, now that wasn't-"

You were getting closer to him 'stop (name)! Stop, don't do it'

"Cadet what are you-" but he was cut off by your lips, his eyes widened, the fact of you kissing him was mind blowing for him, he notice a tear escape your eye.

'Why, why Am I doing this?!' You broke the kiss, you look at Levi who was still shock from the kiss

Your eyes started to water up and left, well almost, you reached the door but Levi grabbed your wrist

"Please let me go!"

"You're not leaving"

"I told you I didn't want to look at you strait in the eyes, I knew I would do that!!" You began to cry and fell on your knees

"I knew *sob* that I wouldn't control myself anymore!"

Levi only stares at you in surprise

"It's hard *sob* it's hard seeing you everyday with the thought of you hating me!"

"Who the hell told you that I hated you"

"I know you hate Titans*sob*, and you hate Nii-san cause his a Titan Shifter *sob* and I'm a Titan Shifter too-"

"Just because I hate Titans doesn't mean I hate your brother or you"

You look at him, he let go of your wrist and got closer to you

"But *sniffle* the way you treat Nii-san"

"Is a way to discipline him, that's all"

You look down and sniffled

"And I don't hate you, I never did nor could I, even if I try"

You look at him, he puts his hand on your cheek and dry your tears

"Now stop crying, you shouldn't cry for something like this"

"What do you mean, that me loving you doesn't matter" then you covered your mouth

"Wait, I didn't-" Levi took your hand to uncover your mouth and smashes his lips with yours, you were surprised at first but the kissed back.

You wrap your arms around his neck and he place a hand on your waist while the other one played with your tail, you moaned, Levi smirks and bite your bottom lip, you gasp and he slip his tongue inside your mouth, exploring every inch of your mouth you moaned with pleasure. This event lasted a two or three minutes and being human and having the needs of air you two departed, resting your foreheads on each other

"I do love you" was all he said before he started to pet you, you purred but covered your mouth, Levi smirk and whispers in your ear "you beater stop hold dose purrs" you blushed

"But, it's embarrassing, and it makes me kinda sleepy"

"Tch, after dinner, come back here with your sleeping wear"

You gave him a cute innocent confuse look

"Just do it"

"Ok Heichou"

"Levi, call me Levi from now on"

You smile and your tail started to wiggle to the side of how happy you were

"Ok Levi"

You were at the mess hall eating your dinner, when you see Eren coming to your way

"Hey, um (name)?"

"What Eren?" You felt weird calling him Eren

"Look I'm sorry"

You look at him "what?"

"I'm sorry for everything"

You got up and hug him "is ok, I'm sorry too Nii-san"

You back up "you better stop overprotecting me"

"Why, you like someone"

"More or less"

"Who's the bastard, I swear if he touch you I'll-"

"You'll what brat"

Eren flinched, he didn't expected the corporal to be there

"Sir I-"

"You'll what Yeager?, you'll beat the crap out of me, I would love to see you try"

"Sir I-I-I"

"Not so tough now, huh Nii-san?"

"S-Shut up"

Eren looks at Levi "but wait sir, are you saying that you, and my sister, are. A thing?"

"Yes stupid"

"Oh well, to be honest I prefer her being with you, than with any bastard in this place"

"I will not give you another week of cleaning duty since we both agree on something"

Eren sigh of relief "oh and umm, I don't know if I should say this"

"Spit it out"

"Just, Don't get my sister pregnant at this young age"

You ear twitched "what the- Nii-san!?"

Levi smirks "you think I'll get her pregnant"

Eren got nervous '(name) is going to kill me'

"Is that at the age she is-"

"Don't you dare say it cause I'm not like that"

"Really?" They both said

"Yes really, I'll wait thank you very much" and with that you left

"Man she hates me now"

Levi smirks and pads Eren on the shoulder

"She doesn't, I'll make sure of it, and no I will not get her pregnant"

Eren nods "thank you sir"

Levi tch "whatever" and left

~~~~~~~~~~Time Skip~~~~~~~~~~

Levi opens the door of his office and by surprise he finds you sitting on the couch but with your arms cross to your chest.

"I thought you wouldn't come" he said while walking towards you

"Yeah well, your lucky I love you" never meeting his gaze he sits next to you and starts to pet you, you were holding your purrs then one of Levi's hand made his way to your tail and strokes it, you couldn't hold it

"Purr meow purr" you started to purr and went on top of him and berried your face on his neck and start it to kiss his neck

Levi chuckles at your action "got turned on huh?"

Still your face on his neck you shake your head "no, I just wanted to do that, it's all"

Levi smirks and picks you up bride style "so you do get sleepy"

"I told you"

Reaching his room he place you on his bed

"Stay hear I'll be right back"

You just nodded

Levi left, after a few minutes he came back shirtless but with pants

You blushed and looked away "w-why aren't you wearing a shirt?"

Levi got on the bed "cause I want to feel your skin"

You turn bright red "wh-what?!"

"Shh" he said then placed your head on his tone chest and starts to pet you, you purred and meowed

"I love you (name)"

"I love you too Levi"

You fell asleep, Levi looks at you

"Tch" was all he did, then placed you in a more comfortable position, he wrap his arms around your waist and you lean closer to him and place a quick kiss on he's chest before falling back to sleep. He shivered a little but kissed the top of your head and fell asleep as well.

The End
