The Edge Chronicles Ch. 06 – Subject 06: Kimiko Tachibana (Pt. 1)

By Kaisai (kaisai134)

Story contains increased beauty, female muscle growth and breast expansion.

5 years ago

Kimiko Tachibana is on her way to school. Kimiko is underdeveloped for her age of 16 being around 144 cm with no feminine curves. She has deep brown hair, brown eyes, and a smile on her face. She just got done watching the latest tokusatsu sentai series of the season and is pumped.  As she walks down the road she is re-enacting her favorite scenes from the series finale.

“Take that!! And that!! And that!!”

She punches the air.

“Ahh! You got me! Curse you!!!”

She throws her hands back behind her.

“Justice will always prevail where evil may lurk!!”

She poses for a few seconds, then returns to walking.

“Today is the day. I can feel it.”

She grips her hands into fists.

“Today, I will finally become a member of the MMA club! And then I will be one step closer to my dream!”

Kimiko spins around and punches the air a few times.

“Today, I will impress them and they will just have to let me in!”

Kimiko approaches the gate to Ryuuzaki Gakuen. As soon as she turns the corner, many different students can be seen walking into the school. A few fights can be seen going on between various clubs. At Ryuuzaki, clubs are allowed to challenge each other to settle differences and scores. Each club decides the challenge and the stakes. Some are physical altercations, others are academic competitions. Kimiko eyes a few members of the MMA club fighting against other members from various clubs.

“I seriously wish they wouldn’t challenge other clubs just because they are stronger. That makes them more like bullies. No worries, once I get in, I’ll change things!”

Kimiko walks on in to class and sits down in front of Kenji Nekotani. He is the president of the Science club. Even though he is a first year, he amazed everyone with his knowledge and skills. They made him the head of the club instantly. He is about 165 cm with black hair, round rimmed glasses, and a lanky build.

“Hi Kimiko, did you see the series finale this morning?” He asks her knowing the answer.

Kimiko turns around to face him.

“You bet I did!”

The two reminisce about the episode until class starts.

After classes are done for the day, everyone disperses to their specific extracurricular activities. Even the Going Home club. Kimiko stands up from her seat.

“Alright! Here we go.”

She runs out the door weaving through the mob of people to where the MMA club meets. She arrives at their room and throws the door open.

“Today you will let me join!” She shouts as she takes a fighting pose.

Nobody is in the room. Kimiko relaxes her stance and sighs.

“Not here. Oh well. Try again tomorrow I guess.”

She walks away dejected. Suddenly she hears a big commotion in the middle of the hall. She sees the entire MMA club standing there intimidating another club. The captain of the club, Sawamura, is having a heated argument with a person in front of him.

“Seriously? But this is my chance!”

Kimiko balls her right hand into a fist and draws it in towards her.

“Hey Sawamura!! Today is going to be the day you let me join!” She cries out as she starts running towards him.

Sawamura turns around.

“Oh, I thought I heard something. No, it was just a small little mouse! Get real!” He replies.

He puts out his hand and stops Kimiko away from his body. She punches and swings wildly. The rest of the club laughs.

“No! I am not a little mouse! I am a fighter of justice!”

Kimiko backs up and jumps in the air hitting Sawamura in the chest with her foot.

Sawamura just laughs at her.

“Was that all? That was weak even for a mouse!”

“I train hard every day to become stronger! I will be stronger than you eventually Sawamura!”

“Beat it mouse, we were just discussing important business here and you interrupted.”

He picks up Kimiko and tosses her against the wall. She grimaces from the impact and sees who Sawamura is arguing with.

“We will not help you bullies one bit with your summer break homework! Maybe if you paid more attention in class rather than figuring out which club to shakedown next, you would actually learn something!” Kenji shouts.

The rest of the Science club nods in unison.

“Fine then. We challenge you to a fight. We lose, nothing happens. If we win, you have to do all of our homework until we graduate.” Sawamura proclaims.

“Okay then. It is a deal, on one condition, you need to lend us a fighter as none of us are in condition to fight.” Kenji counters.

Kimiko rushes back towards Sawamura. He grabs her by her collar and grins.

“Here you go! One fighter. And we’ll even give you time to train the little mouse. How about one month? You have the entire summer to prepare to lose!”

Sawamura tosses Kimiko at Kenji and they crash into each other.

“Good luck, we’ll be waiting for you.”

Sawamura and the rest of the club walks off.

“Owww… And I thought today would be the day…” Kimiko says as she sits up off of Kenji.

She finally realizes who she was on top of.

“Oh my gosh, Kenji! I’m sorry! I didn’t realize it was you!” She apologizes profusely.

All the rest of the Science club members gather around and help Kenji up.

“No problems Kimiko. So looks like you didn’t make it today either.”

Kimiko stands up off the floor.

“Yeah. What was that argument all about?”

“Sawamura and his goons wanted all of us to do their summer break homework. I stood up on behalf of my fellow club members and refused. That is when things got started.”

“Really?!” Kimiko exclaims and balls her hand into a fist. “That is wrong on so many levels! I have really had enough of Sawamura! When I finally make my way into that club, I am going to clean house!”

“No offense Kimiko-chan, but he tossed you like a ragdoll.” One of the members says.

“With your short, underdeveloped body, there is a 0.001% probability that you would defeat him in a fight.” Another one quips.

“Stature and build means nothing when you have a spirit for justice!”

Kimiko stands up proudly.

“And justice is what is going to be served here. You said you needed a fighter, well here she is!”

Kenji looks down at Kimiko.

“Glad to have you on board Kimiko.”

He extends his hand out to her. They shake their hands together.

“Kenji! Are your neural synapses working correctly? She can’t beat Sawamura in a match!” One member shouts.

“Hey, remember who you are talking to.”

Kenji looks back with a smile on his face.

“As she said, stature means nothing when you are committed to justice. Plus remember, we have a month to get her prepared. Just leave it to me.”

Kenji turns back to Kimiko.

“We’ll have a fighter ready in no time. Kimiko, come home with me tomorrow after school.”

Kimiko blushes.

“H… Home wi… with you?”

“Yeah. I want you to come and meet my older sister. I’m going to let her know what’s going on tonight. I’m sure she will be in agreement with what I have in mind right now.”

“What does your older sister do?”

“She’s a scientist. Her work focuses on gene expression and diseases. But she was also a powerful, feared fighter. Knowing her, she will agree immediately with my plan.”

“Okay. I will see you tomorrow then! Bye Kenji!”

Kimiko walks off.

“So, what is your plan all of the sudden?” A club member asks.

Kenji turns around and tells everyone his plan. They all get wide-eyed.

“That is impossible! Not to mention unethical!!”

“Impossible, no. Unethical, only if she doesn’t agree to the idea.” Kenji retorts.

“Hey, it’s our best shot. Or we’re going to be stuck working on 5x more homework for the next 2.5 years.” A member rebuts.

Kimiko walked on home from school. Waiting at home was her older sister Azaka. Azaka is the complete polar opposite of Kimiko. She stands around 168 cm and has a slender body with womanly curves. She had just come home from college. The two of them lived alone together since their parents were more concerned about the family business than anything else.

“I’m back.” Kimiko announces as she walks through the door.

Azaka turns and looks at her little sister in the doorway taking off her shoes.

“Welcome back.” She says with a sweet smile that use to melt people’s hearts.

Azaka is in the kitchen cooking.

“We are going to have some visitors over tonight. I invited my friend from college over for dinner. And she’s bringing over her sibling who is about your age. So go upstairs and change into something a little nicer than what you normally wear around the house.”

“Okay.” Kimiko replies as she walks up the stairs to her room.

As she begins to undress, Kimiko stares at her body in the mirror. Around her room you can see various weights and workout materials.

“Nope. Nothing today. Sis is so lucky. She got all of the good genes.”

Kimiko flexes her arm in the mirror and feels it.

“I can’t even put on any muscle. Sigh. Do I even have it to become a fighter?”

Kimiko gets dressed in a nice light blue blouse and walks back down the stairs and sits down on the couch in the living room and watches TV.

About an hour later, the sound of a car pulling up in the driveway can be heard.

Azaka finishes setting the table and looks up at the clock.

“Perfect timing. That should be them. Kimiko, please go open the door for our guests.”

“Okay.”

Kimiko gets up off the couch and walks over to the door, sees two figures standing in front of it and opens it.

“Hello! Welcome to the… ?!? Kenji?!” Kimiko exclaims when she looks up and sees a familiar face.

“Hi there Kimiko. Isn’t this a pleasant surprise?” Kenji responds with a sweatdrop.

Standing next to him is his older sister Chieko. She is a few centimeters shorter than Kenji with short red hair, a well-toned body with slight hint of muscle, wearing coke-bottle glasses, dressed in a tubetop and skirt.

“Hi Azaka!! We’re here! And we are starving! I hope you cooked something really good to eat!” Chieko shouts as she walks through the door. Kenji and Kimiko still stand there.

“Um… please… come on in.” Kimiko blushes as she steps out of the way.

“Thanks.”

The four of them sit down at the table and eat dinner. Afterwards, everyone gathers in the living room and have fun talking amongst each other.

“Hey sis.” Kenji interjects. “Kimiko here is the student I was telling you about earlier.”

Chieko turns and looks at Kimiko.

“Ah I can see. Kimiko could you please stand up and turn around for me?”

“Um. Okay.”

Kimiko stands up and turns around slowly.

“What did you mean by talking about her earlier?” Azaka asks.

“Uh huh… and I know that short stature and build does not run in your family. Just look at Azaka!! Or should I say Aza-chan!” Chieko says aloud while making a cute pose.

“Chieko!! Answer my question!!”

“Oh right!! Well it seems like little Kimiko here is going to stand up for Ken-chan’s Science club at school in a big fight when school gets back in session with the MMA club.”

Azaka looks at Kimiko.

“They didn’t let you in again and so now you are challenging them with another club?” Azaka puts her hand on her head and sighs.

“No! It’s nothing like that! Kenji accepted the challenge and then that Sawamura picked me up and threw me at him when he asked for a fighter!” Kimiko retorts. “I have the skills to beat him! But, just not the strength…”

She pulls back her sleeve and flexes her arm. Nothing pops up.

“What I asked sis about is helping us turn Kimiko into a powerful fighter during the break. Speed up the process a little bit.” Kenji adds. “I’m thinking a combination of different secretagogues for hormones and growth factors. What do you think sis?”

“Hmmm. That would work. The secretagogues would increase her levels, causing more rapid growth… but I’m thinking there is something more going on…”

“Secretawhat?” Azaka looks at them puzzled.

“Increase my levels?” Kimiko joins in.

“Basically supplements and chemicals that would cause her body to produce more hormones and growth factors, but I don’t think that is what is going on.” Chieko explains.

“You are not talking about steroids are you?!” Azaka shouts.

“No! Nothing like that! These utilizes the natural products within her own body.” Kenji clarifies. “Kimiko is too cute to want to pump her full of steroids.”

Kimiko blushes.

“Ahhhh…”

Chieko grins.

“Kimiko-chan, so when is it your time of the month?”

Everyone else gets red faced at the question.

“My… my… my…”

“WHAT DOES THAT HAVE TO DO WITH ANYTHING SIS?!?”

“Chieko… subtly is not thy name.”

Chieko looks around.

“What?! Ken-chan you read about the female reproductive system when you were only nine years old?! That shouldn’t embarrass you one bit! And you should be following my logic! And c’mon, we’re all girls here! We can discuss this!” Chieko exclaims.

Kimiko looks embarrassed.

“i..don’t. have… one.” She whispers.

“Sorry? I didn’t catch that?” Chieko leans in closer.

“I don’t have one…”

Chieko jumps up from her seat.

“I KNEW IT!! KIMIKO-CHAN HAS NOT GONE THROUGH PUBERTY YET!!”

“How in the world did you figure that out? It is true she has a delayed puberty. That’s what our pediatrician told us.” Azaka asks.

“It is quite simple! Look at the way she looks at Ken-chan. She surely has a schoolgirl crush on him!”

Kimiko’s face turns bright red.

“Nnnnnononono… I don’t have a…” She stammers.

Kenji just laughs.

“And here I thought I was the only one who thought there was an attraction between the two of us.” He says with a wink and a smile.

Kimiko looks over at Kenji.

“Really?!?”

“Congratulations Kimiko, your first love!” Azaka smiles at her.

Kimiko faints.

Kenji looks at her on the floor still red faced and passed out.

“Ummm… I’ll go get her a washcloth or something out of the bathroom. Where is it at?”

Azaka points down the hall.

“Thanks.”

Kenji walks down to the bathroom.

“Seriously Chieko, just by noticing she has a crush?” Azaka looks at her friend.

“Yep! Because at her age, she would be thinking of something a little more different if you know what a mean?” Chieko grins slyly.

Azaka takes a minute and begins remembering when she was Kimiko’s age staring at the most popular guy at school, Yamato, and sitting there licking her lips when he first passed by.

“Okay. I see your point. But no offense, Kenji is not that much of a looker.”

“I guess she has higher tastes than you do!!” Chieko laughs.

Azaka punches Chieko in the stomach.

“Okay… yeah… I deserved that one.” Chieko says as she holds her stomach.

Kenji returns with the washcloth and applies it to Kimiko’s forehead.

“So, what is your plan?” Azaka looks at Chieko.

“Plan? You mean you’re going to agree with it?!”

Azaka looks down at Kimiko.

“I would love to see my little sister finally grow up and achieve her dream. I was able to achieve mine of becoming an idol, I want to see her achieve hers of being a savior of justice. She has all of the skills, the motivation, but her body just won’t do what she wants.”

She then looks back at Chieko

“So if you know of a way, go right on ahead.”

“What would your parents think?”

“What parents?” Azaka looks disgusted. “I raised Kimiko practically on my own. Too worried about that damn family legacy to care any about their daughters.”

Kimiko begins to wake up and sees Kenji with the washcloth.

“Thanks. I.. I didn’t mean to…”

“No worries here Kimiko.” Kenji replies with a smile.

“So here is what I propose. I will work on a drug that will kickstart Kimiko’s puberty, Ken-chan will focus on making a cocktail for her to take to help speed up her growth within the month! And Kimiko, as a fellow fighter…”

Chieko tilts her glasses, showing her red eyes.

“You’d better train your ass off until you can’t train no more. I would love nothing more than to see someone who could take me on in a match one-on-one. I want to see you at the end of next month looking as if people would be crazy taking you on!” Chieko grins wickedly.

Kimiko looks at Chieko with a sweatdrop.

“Ummm… sure…”

Chieko tilts her glasses back up.

“Then it is settled!! Kimiko, on the first day of summer break, come over to our house. Azaka you too!!”

“Okay!” Kimiko shouts as she jumps up from the floor.

“Sounds good to me.” Azaka agrees.

Kenji stands up from the floor.

“I’m so glad everyone agrees on this. Sis, should we get going then? Sounds like we have a lot of work to do.”

“Yes!! There is LOTS of work to be done!! Kimiko-chan, Azaka…”

Chieko quickly pulls out a few Vaccutainer tubes, alcohol pads, and phlebotomy sets, suddenly wearing gloves.

“Can I please get a blood sample from both of you?”

Azaka looks wide-eyed at Chieko.

“Where in the hell did you?”

Chieko looks at Azaka.

“Never question a scientist. We always come prepared for anything!!”

A few days later, Azaka and Kimiko are seen driving to Chieko and Kenji’s house. Azaka pulls in the driveway. Both of them walk up to the house and knocks on the door. Chieko answers the door.

“Hi!! Please!! Come on in!! Everything is finished and ready to be administered!!”

They walk in, take off their shoes and follows Chieko. Kimiko notices the big trophy case along the hallway with various trophies, medals, and awards. She also sees pictures of Chieko when she was a fighter.

“Wow! Kenji wasn’t joking when he said you was a famous prize fighter!” Kimiko says in awe.

Chieko laughs to herself and pushes up her glasses.

“Those were the days. How I miss those days some days.”

Azaka grins. “I think the two funniest moments were when every fighter in the arena ran like little babies when you entered and stood in the middle…”

Chieko grins.

“Or when you fought the bear.”

Chieko’s grin drops.

“… Let’s not talk about the bear…”

Kimiko laughs.

Chieko leads the two of them into the lab.

“Sit down over here Kimiko-chan.”

Kimiko sits down as Chieko walks off and notices Kenji sitting at the computer.

“Hi Kenji!”

He turns around.

“Hi Kimiko. So are you ready to start becoming the fighter you always dream of?”

“You bet! I couldn’t sleep one bit last night.” Kimiko replies.

Azaka takes a seat off to the side.

“I will vouch for her on that. She was punching that bag all night trying to burn off her energy.”

Chieko returns with a vial filled with a clear liquid and a 20cc syringe. She starts rubbing the vial between her palms. Kimiko looks at the vial.

“So is that the drug you were talking about?”

“You betcha! This is a genetically engineered recombinant peptide expressed in a vector of bacterial origin of a fusion protein of gonadotropin-releasing hormone AND growth hormone-releasing hormone!!” Chieko replies.

Azaka and Kimiko both look confused.

“She means it is a synthetic protein of the two hormones that start being secreted during the start of puberty.” Kenji clarifies.

“Oh! Okay…” Kimiko responds.

“Just these have been modified to linger a bit longer. About a day. But that is all we need to get that engine started! Once we start it, your body will take over from there!”

“Okay! Then let’s get that engine started!” Kimiko shouts in glee.

Chieko draws up the entire vial into the syringe, caps it, and walks over to Kimiko with the syringe in hand.

“Alright Kimiko-chan, let me see your stomach.”

“Stomach? Not my arm?” Kimiko questions as she pulls up her shirt.

“Protein, has to be given subcue just like insulin.” Chieko responds.

“Chieko,” Azaka interrupts. “Are you sure this is going to work?”

Chieko turns towards Azaka.

“Azaka! You are forgetting who you are talking to!! I am Chieko Nekotani, currently the 2^nd highest student in the molecular and cellular biology program who discovered a new gene that no one has ever found before!!”

Azaka laughs.

“Go on ahead then.”

Chieko turns back facing Kimiko.

“Alright. This is going to pinch.” She states as she injects the drug.

Kimiko cringes a little bit.

“And we’re done!!” Chieko says as she caps the empty syringe. “Alright, we are going to give your body a few days to adjust, and then Ken-chan takes over!” She then looks over at Azaka. “You may want to stock up heavily on food. She’s going to be a growing girl now you know?” Chieko winks.

Kimiko smiles, stands up, looks down and flexes her arms.

“I know I can’t wait!” She says enthusiastically.

“Go on home. I’ll send Ken-chan over in a few days to start the next phase. You just get ready to start training like crazy!”

Kimiko nods as she and Azaka begin walking out to the car.
