Hi, guys! I hope I didn't make you wait! This is the third chapter of "My Genius Sister"!

Firstly, I'd like to thank Stargazer-Aika, clover 4 leaves, arkcess, Nikka-Chan, DarkEnforzer, alex, Ashley Silver, hiyomi, Chocobo1374, Guest, AoiHana26, KK, and QuantumComplexity for reviewing the previous chapter. Please review again! *heart*

Also, partly under the suggestion of alex, I had decided to begin the friendship between Annie and Eren! Actually I had planned this from the very start since Annie is my favorite female character after Mikasa, but oh well!

And then, for the two questions in the previous chapter, namely "What anime did I get the idea for the scene where Mikasa got the score exceeding 100 from?" and "Who said the last line of this chapter?", most of you gave the right answer for the second question. As for the the first question, only one of you answered it, and the answer was perfect! Yes, jneth1lary88, I got the idea for the scene from the anime 'Special A'! XD

He placed his hand on her head, rubbing it gently, "No, you did nothing wrong. I was, you know, too emotional back there."

Relieved, Mikasa faintly smiled.

It was before someone suddenly barged into the class, followed by two others.

"Is Mikasa Ackerman here?"

Mikasa turned around to face the person looking for her. After recognizing the person, Mikasa quickly presented herself in front of him.

"I have something I need to discuss with you, Ackerman."

"What might it be, kaichou?"

Eren examined the person talking to Mikasa. He was a lot shorter but certainly wore the expression of an older man capable of calling himself asenpai. And after a while, Eren realized he knew this person. He saw him when he accompanied Reiner to the Student Council room to submit their class' decision for culture festival event. He was Rivaille-kaichou, a third year, and the student council president of the school. Beside him was the vice president, Irvin-senpai. And the other person was Hanji Zoë-senpai, the secretary of the student council.

But what did those important people have to say to Mikasa?

"I believe we shouldn't talk here where this many people gather. Come. We will talk in the Student Council room."

"Yes." Mikasa turned around, "I'll be going, Eren." She reported.

Eren nervously nodded.

When Mikasa left, the class started whispering about what Mikasa could have done to be summoned to the Student Council room. Usually, only problem children got summoned there. But Mikasa was the top student of their year and she had never done any mistake huge enough for her to be punished.

But then Eren heard Ymir mentioning something he never expected.

"This is not the first time Mikasa's summoned there, right?"


Chapter 3. Untold


That day, Mikasa spent most of her time in the Student Council room.

Not having committee work, Eren decided to go home ahead of her—since she decided to stay at school for a while—accompanied by Armin. And while still thinking about why Mikasa was summoned to the Student Council room, Eren pondered all the while walking home. Getting worried, Armin asked him what he was thinking.

"What could possibly cause Mikasa to be summoned more than once to the Student Council room?"

"Err… that's… Maybe they're informing her of her achievements?"

"Why would they need to do that? It's the job of our homeroom teacher."

"I know! Mikasa must have participated in an Olympiad!"

"She'd have told me if she did."

"Ugh… Err…"

Just as Eren was deep in thought again, he noticed someone familiar down a narrow alley he just passed. He took a step back and peaked into the alley once again, followed by Armin. There, they could see the familiar small figure of a girl. She was wearing the same uniform as them, only she had white hoodie under her chocolate blazer instead of a blouse.

"Annie? What is she doing there?" Armin asked.

On the other hand, Eren had already learned the situation, judging by four bigger men surrounding the petite blonde. He had seen it happened to Mikasa several times. They were hitting on her. Eren gulped at their bravery to approach a scary girl like Annie; just looking at her face sent him shivers.

But as scary as she was, Annie was still a girl, and a frail one at that, judging by her petite size.

Eren had the urge to save her, only before the four men suddenly attacked her in unison and the scene happening before his eyes betrayed his imagination. With her small body, Annie easily escaped the four men's grip, creating a chance for her to kick each of their ankles hard enough for them to lose their footings. One by one, they tried to stand up only to get arm-locked by Annie, and with a single kick they ended up in a somersault pose.

The girl left the scene, barely sweating.

Amazed, Eren didn't realize that he had been holding his breath.

"Ah." Annie seemed to have noticed Eren and Armin's presence. "Close your mouth, Eren, your jaw is falling."

Flustered, Eren quickly did as he was told.

"Forget that! Annie, you're amazing! Where did you learn those cool moves?" Eren asked excitedly, eyes sparkling.

"From my dad…"

"Cool! Can you teach me—"

"I barely do a thing in class, I didn't join any club, I've never done my job as the class secretary, and I sneak off of my job as the culture festival committee. What makes you believe I'm willing to spend my precious free time teaching you something?"

"Kuh, that's harsh…"

"But…"

At that, Eren lift up his face full of expectation.

"But if you will do my job as the committee, I would reconsider it."

Eren's smile expanded. "That's a piece of cake!"

He was excited as this would be a new subject to learn. He would be sure to hide this from Mikasa or he knew what would happen. That pattern had occurred for more times than he could count. Mikasa would catch up and then she would be the one to teach him. And he didn't want that. He would train with Annie in secret and out of Mikasa's knowledge.

"Is after school alright with you? I have part-time job in the evening."

"Anytime is fine! But Annie, I would never expect you to work."

"What do you expect from someone living alone? I have to cover my living expenses." Annie muttered, tucking her hair behind her ear.

"Whoa!" Eren's eyes sparkled again and Annie slightly jerked away. "You're really amazing, after all!"

"Stop making it sound grand. I just work because I need to eat."

"Still, it's cool!"

"Whatever," Annie sighed.

Eren noticed her expression changed. It was an unreadable expression that he was incapable to understand. Her eyes had a distant look as though she was reminiscing something from a long time ago; something she didn't want to remember.

"Annie?" Eren called.

"I guess that's it. See you tomorrow," she said before she left.


When Eren arrived home, Mikasa was already there, cooking dinner.

"You're cooking this early?"

"Yeah. I'm going out tonight, make sure you eat dinner."

"Going out? Where?"

"Work. Don't worry, I'll try to return as soon as possible."

"What? You never worked at night before."

"I changed shift."

Eren scowled, getting suspicious. But he decided to ignore it and went to place his bag on the couch.

"The water's ready. You can take your bath, Eren."

"Oh, thanks."

Eren entered the bathtub as soon as he entered the bathroom, sighing in content afterward. In the quiet room, Eren started pondering again, about why Mikasa was summoned to the Student Council room and why she suddenly changed her work shift. Then he suddenly realized. His thought had been full of Mikasa alone all day long.

He splashed the hot bathwater on his face, refreshing himself.

He reached for the soap bottle and pumped it but nothing came out.

"Mikasa! Do we have spare soap? There isn't any left here!" he shouted for Mikasa.

"I think we have! Wait a moment!"

It didn't take long for Mikasa to suddenly barge into the bathroom without even bothering to knock. She was still wearing her apron, meaning she hadn't done with the cooking.

"Here. Give me the empty bottle."

"Ooh…—That's not it! You should at least knock before entering! We're all grown up now!"

"Is that so?" Mikasa looked over her shoulder. Eren could've sworn he saw the faintest smile on her lips. "To me, Eren is always a child…" she said before she left.

"Huh!?"


The doorbell rang not too long after Eren got out of the bathroom.

"I'll open the door!" Eren shouted.

"Um. Thanks," he heard Mikasa's reply.

Opening the door, Eren jumped back slightly when he saw who was behind. The height difference forced him to tilt his head down a bit. The person had jet black hair and sharp grey eyes, similar to Mikasa.

It was Rivaille-kaichou, dressed in formal suit.

"I heard you and Ackerman are foster siblings. But seeing you two living together like this, you look more like a young married couple, Jaeger." There was a chilling grimace on Rivaille's face.

"E-eeto… May I ask why you are here, kaichou?"

"I am here to fetch Ackerman."

"Huh? For wha—"

"Eren? Who is it?" Mikasa came out from the kitchen.

"Mikasa?"

"It's me, Ackerman. It is almost time and I believe your tardiness benefits no one." Rivaille said while showing his pocket watch, which showed that it was 06:45 p.m.

"Ah, forgive me. I'll get changed fast."

Mikasa trotted into her bedroom, or to be precise, her and Eren's shared bedroom. In less than five minutes, Mikasa came out dressed unusually elegant. She was dressed in a one-piece pink dress that reached her knees. She was also holding a Louis Vuitton purse which Eren never recalled to had seen even once. And lastly, the red scarf around her neck seemed out-of-place.

"I'm going, Eren. Be good."

Eren could hear Rivaille snorted at how Mikasa sounded like a mom.

Eren grabbed Mikasa's shoulder, "Wait! Mikasa, I thought you said you're going to work?"

The girl looked over her shoulder for the second time today, "This is work. I'm accompanying Rivaille-kaichou somewhere. I can't tell you any more. But don't worry if I did great we will have enough money to buy that game console you wanted." She slightly smiled at him.

She always did everything for him. She barely spent the money she earned for herself. She had scholarship so she didn't need to pay the school fee and she barely wanted anything normal girls would usually beg for. Most of her money was spent on him.

She was selfless.

Mikasa slowly removed Eren's hand from her shoulder and went with Rivaille.

"I'm going, Eren."

Eren slowly nodded as the door closed.

He slowly walked toward the dining room to see his dinner placed neatly on the table and slowly sat down and picked up his spoon. But he was too bothered to even eat. He couldn't even start imagining what work Mikasa was talking about. She never told him anything, and ironically, he never asked her about it before. He was being too uncaring about her.

And on top of all, Rivaille's presence just now really bothered him.

How the hell did he know of Mikasa's work while he didn't?

Eren shook his head fiercely and tried to forget about those and focused on eating dinner.

He entered a spoonful of Paella into his mouth. The taste spread inside his mouth. It tasted wonderful. He hated how Mikasa could develop this much every day. He hated how she tried her best to please him.

He hated how she never thought of herself but instead worrying about him.

He hated everything about her.

Eating another spoonful, he gritted his teeth, "I hate you, Mikasa."


Today, Mikasa stayed at the Student Council room after school again. But unlike yesterday, Eren didn't go home ahead, since he had committee work today. And not to mention, he had to make sure he did Annie's part as well.

"You work a lot today, Eren! If this is a real job and I'm your boss, I'll raise your pay!" Reiner laughed.

Today, Betholdt was also helping out. The tall guy smiled at his friend.

"Actually, Annie told me to do her work in her place or she won't teach me those cool moves." Eren laughed nervously, scratching the back of his head.

For some reason, both Reiner and Bertholdt stopped their track.

Eren turned around, "What's wrong?"

"Eren, what do you mean by cool moves?" Reiner asked. Cold sweat seemed to have formed on his forehead. And Bertholdt didn't look any better.

Eren had started to grow uneasy as well, "Eh? It's just the self-defense moves that I saw her use on some guys yesterday… What's wrong with that?"

Reiner and Betholdt exchanged frightened looks.

"When did she start again?" Reiner asked Bertholdt.

The taller guy shook his head, "I didn't notice at all."

"What are you guys talking about?"

Reiner faced Eren again, "Listen, Eren, I don't know how Annie agree to teach you. If you really want to, I won't be holding you back, just… you just might be able to help her. She is—"

"Hey, Eren, are you done yet?"

The three of them jumped at the voice. The subject of their talk, Annie, was standing at the end of the corridor, one hand on hip.

The blonde quickly approached them in quick pace and Reiner got away from Eren as quick.

Annie pulled Eren with her out of his will, and when she went pass Reiner, she whispered coldly, "You talk too much, Reiner…" and left.


The look on her face didn't look any different than usual, but Eren could tell that Annie was bothered by something. She seemed to be spacing out for a while now.

"Hey, how are you going to teach me anything if you're just standing there like that?"

"…" she glared at him and he jerked away in fear. "Come at me." She set her pose, her lower arms raised to head level, as though it could protect her from anything.

"What?"

"Moves are most effective when tested on yourself."

"What!?"

"Come!"

Eren groaned in protest, but it seemed he didn't have any choice left. He launched himself to Annie, and as expected, he ended up in somersault pose in less than five seconds.

"What the hell! You did it too fast I can't see a thing!"

"Of course you can't."

"Then what's the point in doing this!?"

Annie looked at the side, "To tease you."

"HUH!?"

Annie's lips pursed slightly, "Now. Let's proceed to the real training."

"I'm really getting mad, you know!?"

Annie ignored him and offered him a hand to stand up. Once he stood up, she took his left arm and wrapped it around her neck.

"A-Annie!?"

"Shut up, I'm showing you the way."

"O-okay…"

"You use your hand and push your enemy from the front and kick their ankle like this, hard. They will need time to get up and you use that short time to run away."

"Run away!?"

"Oh, you're strong so I think you don't need to run away. On the other hand, I am a frail, weak maiden so I need to."

"Yeah, yeah, whatever, like anyone would believe in that bullshit."

"Alright, you can practice in on me."

"Huh? Are you sure? I don't think it's manly to hit a girl."

"Oh, what a gentleman. Gentlemen die in the hands of evil women."

"Okay! I get your point! Don't blame me later, okay?"

"Of course."

Eren did as he was taught. He tried to wrap his arm around Annie's neck but the girl had the speed of lightning. She quickly slipped off Eren's grip and kicked his ankle, making him lose his footings.

"Ouch! What the hell's that for, Annie!?"

"I said you can practice on me. I never said I will quietly let myself get into that humiliating pose by you."

"Why you…" Eren growled.

"You can practice it on someone else, maybe on people like the ones who attacked me yesterday? Many people would thank you for that."

Eren sighed in defeat. He finally realized that he could never beat this girl in an argument.

"How is it? You still want to continue this training?" she was smiling somewhat challengingly, as though she believed he would beg to stop.

"Of course! I will not stop until I can master it! I won't let Mikasa win this time!"

Annie's eyes widened. Is this guy for real?

Annie felt as though she could see fire flickering inside his green eyes. He endured everything for the sole purpose of defeating his so-called sister, Mikasa Ackerman. Annie suddenly realized how much this meant for him.

"You're a weird guy."

"Yeah, living with Mikasa for years has robbed my sanity."

Annie laughed softly.

That was the first time Eren had ever seen her laugh. He was a little, although only a little, fascinated by it.


Mikasa was sitting on the couch with a black dress in her hands.

Everyone had gone home and she was the only one left in the room aside from the President. While the President was checking some documents, Mikasa massaged her temple and then sighed. She was getting quite tired after only one night shift.

"Do you think you can handle the night shift, huh? I can always change back your shift if you're not doing well. Just so you know, no one's going to bring you to the hospital if you collapse."

The girl shook her head slowly, "No. There are many, many things I need to prepare. I really need the money."

"Just keep your health in check, dammit. No one's going to choose an ill bitch."

Mikasa nodded. Her grip on the black dress on her lap tightened.
