The Edge Chronicles Ch. 06 – Subject 06: Kimiko Tachibana (Pt. 2)

By Kaisai (kaisai134)

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

The next few days pass. Kimiko has begun to notice some changes. Her appetite has been increasing steadily. She is beginning to feel some pains in her joints. And her flat chest has begun to start budding. Kimiko is outside jogging when Kenji drops on by.

“Hi Kenji!!” She calls out to him.

“Hi Kimiko. So anything starting to change?”

“Very little. I feel some pains once in a while and I’m hungrier than usual.”

“Good. That means your body is starting to grow.”

Kenji pulls out a small pill bottle and hands it to her.

“Here you go. This should help kick things into overdrive.”

“So this is those secreta-thingamabobers?”

“That is right. The capsule is a quick dissolve, it has fast onset and long duration. So basically about 10 minutes after you take one, they get absorbed in your blood and begin working. Only take one a day. And also take 10 minutes before you start working out and training for maximum effect.”

Kimiko takes out one of the pills and looks at it. Just a simple non-discrete capsule.

“Bottoms up!” She says as she takes the pill and swallows it with the water in her water bottle.

“Alright then. I will come back and check in on you in a few days then. Good luck Kimiko. I’m really excited to see what happens.”

“In a scientific way or in my way?” She asks him.

“Do I have to choose?” He smiles back at her.

“Hahaha.” Kimiko laughs at him.

Kenji walks off as Kimiko walks back into the house. She runs upstairs and begins setting up her weights. After 10 minutes since she swallowed the pill, she begins feeling something weird.

“Wow! What is this feeling?! I feel like I’m full of energy!”

Kimiko cracks her knuckles and looks at her weights.

“Let’s put this energy to good use!”

Kimiko begins working out harder than before. As she works out, her body begins growing slightly. She gains a centimeter all around. And her muscles begin to grow. Kimiko finishes her training for the day when Azaka calls her for dinner.

“Kimiko! Dinner is ready!” Azaka calls out.

Kimiko finishes kicking the sandbag.

“Right! Be down in a second. I’m starving!”

She ran down the stairs to the kitchen.

She repeats the same routine for the next three days. She is slowly growing. Her body is starting to fill out in all the right places. She is gaining height, her muscles are responding well to the training, now beginning to look like she has some. Azaka begins noticing the changes as well.

“I see someone finally needs a training bra.” Azaka quips while watching Kimiko working out.

Kimiko stops and looks down seeing her breasts and grins.

“Do you have one I could borrow? I don’t know how long I’m going to be in it?” Kimiko asks joyously.

Azaka walks off to her room, grabs one, and then walks back.

“Here you go.” She says as she hands the bra to Kimiko.

“Thank you!!” Kimiko hugs Azaka tightly.

“Not a problem. Hey, you’re starting to get a little stronger there!”

Kimiko releases Azaka.

“I know! Just look at the weights I’m using now. I’ve almost doubled what I could before!”

Kimiko tights up her fist and flexes a small bump.

“It is finally starting to happen. I’m finally getting my wish.”

“Alright, I’m going down to start fixing dinner.”

“Okay! I’ll be down in a few minutes!”

Kimiko starts to put on the new bra. As she starts to snap it, she watches as her breasts swell a single centimeter.

“I wonder how long before I’m going to need a new one.”

Next day, Kenji came by to check on Kimiko. He walks on in to the house.

“Hi. It’s me Kenji. I just came by to check on Kimiko, see how she is progressing.”

Kimiko walks down the steps with a 7 kg dumbbell in hand.

“Hi Kenji!” She greets. Her voice cracking.

Kenji stands there taking in the site. He can tell she has already grown at least 5 cm in height and is developing some breasts. She is starting to put on more muscle.

“Hi Kimiko! Wow! You are really starting to grow. I am really amazed!”

“Me too!” Kimiko sits down the weight and twirls around. “Do you like what you are seeing?” She asks playfully while posing.

“Definitely. No doubt in my mind that I like what I am seeing in front of me.” Kenji replies.

“Hehehehe. I have a strong feeling there is still a lot more to come!”

“I can’t wait to see it.” Kenji responds with a sly grin.

Kimiko started growing at a faster pace. She was starting to gain a centimeter of height a day. Her bust was developing at the same rapid rate, her waist was growing with her body, but still keeping tight from the training, and her hips were slightly larger than her bust, but also growing. She keeps getting stronger, and stronger. Her muscles continue to grow and expand with her body, still maintaining that athletic look, now starting to look even more athletic. Another change is her hair is growing longer. Kimiko begins putting her hair in a low braided ponytail.

Azaka walks in on Kimiko and rubs her head. She notices Kimiko is now almost 20 cm shorter than she is. And her muscles are starting to get really defined.

“Hey there little sis. Here is the new bra you asked for.”

Kimiko drops her 16 kg weight and turns around.

“Thanks again. This one is starting to get somewhat tight.” Kimiko replies in a now more mature sounding voice.

“I know Chieko and Kenji said rapid, but I didn’t think this rapid.” She says as she hands her the bra.

“I’m not complaining any! I just can’t wait to see Sawamura’s reaction when he sees what the little mouse has become.” Kimiko says as she takes the bra.

“Hey, the agency is wanting all of us girls to get together for an idol festival for about five days starting tomorrow. I’m going to be out of town for a little bit. You going to be okay by yourself?” Azaka asks.

Kimiko takes off her shirt and is putting on her bra. Her breasts can be seen about to push out of the old bra with the straps being under tension. A noticeable six-pack is forming on her abdomen.

“No problem. I’m a big girl, I can take care of myself.” Kimiko smiles back.

“Haha. Very funny Kimiko.” Azaka rubs her hair again. “Alright, I’m going to go start dinner and start packing.”

“Okay! I’m going to finish my exercises. That sandbag is really taking a beating now!”

“I bet, I don’t think it knew you would be actually growing into a fighter of justice.”

“Exactly!” Kimiko grins.

Azaka leaves and Kimiko begins punching and kicking the bag. Kimiko’s eyes start glowing a faint white as she feels some pressure beginning to develop around her body.

“What is that?!”

She stops attacking the bag and looks down at her body. She starts to see a light-bluish light gathering around her hands as her eyes fade.

“That is new…”

The next day, Azaka leaves for her trip. Kimiko waves good bye and walks over to where she is keeping the pills Kenji made for her. She takes her daily dose and prepares for her workout routine. When the pill kicks in, her eyes begin glowing again and the light around her hands returns. She sees this as she ties her hair in the mirror.

“It’s happening again!! What is going on?!”

Her eyes fade but the glow around her hands still pervades.

“What is this?!” She screams as she hold out her arms. She starts focusing on the energy and it goes away.

“Okay…”

She brings her hands back in.

“That is really weird. But, I wonder…”

She makes a fist and concentrates. The energy begins glowing around her fist. She stops concentrating and it fades away.

“I can control it…”

She starts her training, now adding in her newly developing abilities. Flashes of light can be seen flashing as she punches and kicks the sandbag which is now really moving back and forth. She stops and goes to do her daily weight training. She walks down into the basement where they had just set up a weight machine for her since she’s outgrowing the free weights. She sits down and works her routine. Near the end of it, she feels a strong growing pressure around her body as she grows 2 cm. Her muscles swell slightly more as well. She gets up and starts performing her katas that she started working on. She hears the doorbell and walks up the stairs to answer it.

“Hi Kimi… WOAH!!” Kenji almost loses his glasses.

“Hi Kenji! Please come on in.” Kimiko says while leaning back on the doorframe flexing her arm.

“Su… su… sure…” He stutters as he walks on in.

Kimiko walks into the kitchen and gets the two of them something to drink. Kenji sits down in the living room still trying to comprehend what he is seeing.

“So. It looks like your growth has really picked up. You are starting to get up there!”

Kimiko sits down beside Kenji and scoots in handing him his drink.

“I know! I am pretty amazed myself. Part of me is scared, but the other is excited beyond belief!”

Kenji looks down and sees her wearing a halter top that is starting to look tight. He notices her breasts swell a bit. He gulps.

“There is something I do want to show you, a new development!” Kimiko gets in closer.

Kenji gets a blush quickly jumps up.

“I…I…I… I gotta go Kimiko! I’ll be back to check on you in a few days at the end of the treatment…”

He begins rushing towards the door hurrying to get his shoes on.

“Wait Kenji! I really do have something to show you! I know you’ll be excited!!”

Kimiko stands up and starts walking over to him.

“Y… Y… You can…. T… t… tell me about it n..n..n..next time. Bye Kimiko!!!”

He runs out the door as she focuses the energy into her hands.

“No Wait!! Kenji!! Look!! Look at this!!!” Kimiko shouts out standing in the doorway.

She looks back down at herself.

“It is almost like I’m starting to become like one of those characters from a fighting game.”

Kenji returns home and explains everything he saw to Chieko. She just busts out laughing and falls out of her chair.

“It’s not funny!” Kenji retorts.

“HAHAHAHAHAHAHAHA!! Oh my God!! You’re right… it’s hilarious!!! HAHAHHAHAHAHA!!!”

“She is developing way too fast! Something is not right!”

Chieko picks herself up off the floor and smacks Kenji in the back.

“What do you mean? You mean the little brother of the great Chieko Nekotani works too well like his big sister?! I think you are one who needs to grow up a bit too! I can’t believe that she was starting to come on to you and you bolted!!” Chieko laughs.

“Sis!!”

Chieko stops laughing finally.

“I will say that amount of development in that short period of time is unheard of. Just continue to monitor her. That’s all we can do.”

“Yeah, that is all we can do isn’t it.” Kenji sighs.

The next few days, Kimiko starts changing her routine. She starts working out even harder, training twice as hard, and starts working on controlling her new abilities. She begins modelling attacks after the main characters of a popular fighting game series. The pace of her growth picks up. She jumps from 152 cm to 159 cm in height. Her breasts are filling out even faster than before. She has had to discard the bra Azaka gave her after a day. Her muscles are growing faster as well. Her biceps are starting to become quite apparent as well with her quads and calves. Her abdomen is continuing to build and grow solidifying into a solid six-pack. Her back is getting stronger to help support her growing bosom.

On the last day of the treatment, Kimiko wakes up and fixes her breakfast and washes up. When she gets out of the shower, she stands in the mirror and really takes a good look at herself. She has a championship athlete build with a perfect hourglass body.

“Wow. It is seriously my dream come true.” She says as she cups her D cup breasts and then flexes a sizeable bicep from her right arm.

“Thank you Kenji! Thank you Chieko! And thank you big sis!!”

She gets dressed in her workout clothes that are now one size too small.

“Geh… I’m going to have to get new clothes again.”

She ties her hair in her ponytail then grabs the bottle.

“Last one. Down the hatch!” She says as she tilts the bottle and swallows the pill.

She chases it with a sports drink.

“And now. Let’s begin training for the day!!” She shouts as she runs down to the weight machine. She sets the machine for 41 kg and starts her weight routine with her eyes glowing white.

Azaka pulls into the driveway and exits the car carrying her luggage. She kicks the car door shut.

Kimiko hears the slamming door in the middle of her chest presses.

“Sis is home! I can’t wait to till she sees how much I’ve grown!” She grunts as she finishes the exercise.

Azaka opens the door.

“I’m back Kimiko! Can you please come help me with all this luggage?”

“Sure! Be there in a second!” Kimiko shouts as she starts bounding up the steps.

Kimiko appears in front of Azaka. Azaka stares and drops all of the luggage on the floor.

“Welcome back big sis!” Kimiko says with a big smile.

“Ki… Ki… Kimiko?!? What?! What?!” Azaka continue to stares at Kimiko.

“I really grew since you left!”

Azaka walks over to Kimiko.

“Grew nothing! You are only 10 cm shorter than me! In just five days!!” Azaka exclaims.

She then looks down and sees the straining halter top.

“Where is the bra I gave you?”

“Oh! I had to stop wearing it after two days. These grew like crazy!” Kimiko says as she points to her bust.

“Get ready. We are going to go see Chieko, now.”

“Okay! Before we do that come outside with me.”

Kimiko motions Azaka on out the back door. Kimiko’s sandbag is outside but has scorch marks on it.

“What do you want to show me? Why is your sandbag out here?”

Kimiko takes a pose with her hands clasped together.

“Watch this!”

Kimiko gathers the energy in between her palms.

“SCREAMING SPIRIT BULLET!!”

She unleashes the blast of ki at the sandbag causing it to fly a few yards.

Azaka stands there in shock.

“Pretty neat isn’t it! Just like a character from a video game or manga!” Kimiko walks over to Azaka and gives her a thumbs up.

Suddenly, Kimiko experiences a growth spurt. She grows 4 more centimeters in height. Her muscles swell a bit more. Her breasts jump up another cup size, pulling the halter top now into a makeshift bra. Her body still retains the hourglass shape.

“Wow that was a big one…” Kimiko looks down at her awfully tight clothes.

Azaka grabs her and takes her to the car. They both get in and drive to Chieko’s.

Azaka calls Chieko on the way saying that they are coming. When they arrive, they both step out of the car and stand at the door. Chieko opens it.

“Azaka, what is the… HOLY SHNIKES!!!!” Chieko shouts and loses her glasses as she looks eye to eye with Kimiko.

Kimiko waves at Chieko.

“It worked!” She smiles.

Chieko still stands in the doorway in shock. Kenji walks by drinking a bottle of water when he spots Kimiko.

“!!!”

He spits out the water everywhere.

“KIMIKO!?!?!”

“Hi Kenji! Do you like what you see?” Kimiko leans down holding her breasts accentuating both her breasts and arms with a wink.

“Now do you believe me sis!!” Kenji shouts at Chieko.

Chieko fumbles with her glasses.

“C... Come inside… now! Meet me in the lab!!”

Chieko runs to the lab shooing away a few kittens.

Azaka and Kimiko enter the door and begin walking to the lab. Kimiko walks by Kenji and giggles at him. He takes a second for his brain to regain control and follows them.

“Kenji. Get me the list of the secretagouges you developed!! Let me see them!!” Chieko shouts as she sits down at the computer.

“Right!”

He grabs the list and hands it to her. Chieko analyzes it.

“Hmm… nothing out of the ordinary except this one you designed for IGF-1… Kenji, run serum analysis for hormone and growth factor levels.”

“Right away.” Kenji responds as he grabs a blood draw kit. “Kimiko, your arm please.”

“Sure!”

She sits down and puts out her right arm. Kenji notices the growth that her muscles have done since he last saw her. He draws the blood and runs the analysis.

“Here are the results sis.”

Chieko analyzes the results.

“They are running slightly higher than the normal range, but nothing that would cause this much growth.”

“She didn’t just grow bigger! She gained some weird superpower as well!” Azaka interrupts.

Chieko looks up.

“Superpower? Like what?!”

Kimiko stands up.

“Here let me show you!”

“DON’T FIRE THAT BLAST OFF WITHIN THE LAB!!” Azaka screams.

Chieko and Kenji stare at Kimiko who is starting to concentrate.

“Don’t fire…” Kenji repeats.

“… that blast…” Chieko continues.

Kimiko draws her ki into her hands and they start glowing.

“See! This is what I was talking about the other day Kenji when you ran away from me all of the sudden!! Look!”

Kimiko holds out her glowing fists.

“How was I supposed to know that’s what you were wanting?! You were acting like you was trying to come onto me?!” Kenji rebuts.

“Seriously?! You really thought that?! Maybe I was acting a little closer than usual?” Kimiko replies. “Sorry, I was just shocked and amazed! And I wanted you to get an up close and personal look at it.”

Chieko starts to grin.

“Okay, you can stop now Kimiko-chan. I’ve seen all I need to. If you excuse me, I need to go run a quick assay. If I am right…”

Chieko starts giggling.

“You are an angel that just fell right into my lap!!”

Chieko runs over and starts running a chromosomal assay.

“Angel?” Kimiko says with a puzzled look while she stops concentrating.

“Yes!! An angel!! Sent down from above!! An angel to prove my theories!!!” Chieko exclaims as she mixes reagents together.

“Kimiko-chan!! What have you been lifting recently?”

“Around 41 kg.”

“41 KG!?!?” Both Kenji and Azaka shout.

“HAHAHA!! And what about your speed?!”Chieko shouts as she starts to swab her mouth.

“I’m running almost 5 times faster.”

“5 times?! But you normally ran around 10 km/hr!!” Azaka interjects.

“HAHAHAHAHAHAHAHAHAHA!!! And all that wonderful muscle mass. It just started developing faster all of the sudden didn’t it?!?!” Chieko inquires as she is adding the labeled reagent to each extracted tube.

“Yeah. It’s almost like they started really growing within the past few days.”

“YES!!! YES!! YES!!! It is all there!!! All of the signs are there!! The phenotype fits perfectly!!!!” Chieko exclaims as she puts the tubes in the incubator.

Kenji turns to Chieko.

“Sis… are you thinking…”

“ORF357139!!! It HAS to be!!! IT JUST HAS TO BE!!!!”

Kenji turns back and looks at Kimiko who has a confused look.

“What is an ORF539…?”

Kenji’s eyes get wide as he begins to notice it as well.

“It is the gene sis discovered located on the X-chomosome. And she is right, now that I look at you…”

Kenji turns around and looks at an old picture of Chieko and him after one of her big wins with a muscular build and a huge happy grin across her face hugging around him.

“You do fit the criteria…”

“Wait a second. Are you saying she’s EXACTLY like you Chieko?!?!” Azaka says aloud.

“Not exactly!! She was blessed with those good looking genes that you have. I mean WHOOO!! No wonder Ken-chan gets all starry eyed around her!”

Kimiko looks at Kenji. Kenji turns around and looks at her. He quickly turns his head away from her. Kimiko giggles.

“And it is now… DONE!!!”

Chieko retrieves the samples and places them on different microscope slides and walks over to the computer where she pulls out a fluorescence microscope.

“LIGHTS!!!”

Azaka looks beside her and turns off the switch.

“Alright. First. Here is a sample of my DNA.”

Chieko puts the side on the stage.

“Notice all of the fuzzy blue bands. Those are the chromosomes. See where on the longest ones they have a bright neon green spot. That is ORF357139. The green is from the fluorescent label that is attached to the probe I designed specifically for that region.”

Everyone looks at the image up on the screen.

Next, up is Azaka’s.

Chieko switches out the slides.

“Notice anything different?”

“No green in my blood.” Azaka says aloud.

“Exactly. She is not a carrier of ORF357139. She is a normal female.”

Chieko takes off the slide and pulls up the next one.

“Here is the moment of truth…”

Everyone continues to stare at the screen as Chieko swaps out the slide.

Everyone gasps while Chieko just sits there grinning wildly.

“Some of them are…” Azaka starts.

“Green.” Kimiko finishes.

“Oh my God. Kimiko is a carrier.” Kenji says awestruck.

Chieko zooms in on one of the X-chromosomes that is glowing with a small area that looks radioactive green in the middle of it. She then turns and faces everyone behind her.

“And now, we know what happened to Kimiko-chan.” She says aloud illuminated by the screen behind her.

“I’m a carrier of this gene? So what now?” Kimiko asks.

“Well, unless you want to end up looking like a bodybuilder, stop strength training right now. As for those new abilities.”

A glint runs across Chieko’s glasses as she grins in the dark.

“Those just need to be studied!!”

A week goes by and it is time for the fated match. Sawamura stands there stretching as all of the other MMA club members sit around and do nothing.

“Well? Where are they?! I don’t have all damn day!!” Sawamura starts getting angry.

“Do you think they ran?! I mean you through the mouse at them!” One member laughs.

“Yeah! I bet that’s it!! We won by default!! Let’s go ransack their room for standing us up!” Another member shouts.

“YEAH!!!” Everyone screams in unison!

“Not so fast! We’re here. We just had to make a slight detour.”

Sawamura turns around to see Kenji and the rest of the Science club standing behind him in the courtyard.

“Oh look who decided to show up! Ready to lose?!”

Sawamura cracks his knuckles.

“Where is she? Where is the mouse?!”

He notices a medium-sized figure in a cloak being revealed from behind the Science club members.

“Wait a minute!? Who is that!? If you got another fighter after we so graciously gave you one that is an automatic forfeit!” Sawamura accuses.

The cloaked figure walks up in front of Sawamura.

“Oh what?! You think you’re going to challenge me punk. You have another thing coming. After I kick this punk’s ass, you guys are next! You hear!?” Sawamura shouts.

The figure just grins under the cloak.

Sawamura swings his right fist at the figure. The figure grabs his fist and holds onto it.

“What the?!”

The figure punches Sawamura in the face, revealing a womanly hand wearing red knuckle gloves with a well-developed arm. Sawamura is knocked back by the attack.

“Oh no. The challenge is still on, you see.” Kenji gives a devious grin.

“Sawamura…” The figure starts talking, everyone hears a womanly voice. “Today is the day where you reign of terror over this school ends! As today, justice will finally be delivered to you and your band of thugs!!”

“Who... Who the hell are you?!” Sawamura stands rubbing his jaw.

“But you know who I am, Sawamura. Here, let me show you.”

The figure throws off the cloak.

Every member of the MMA club stands in awe of the beautiful fighter who stands before them. With her long brown hair that goes past her waist brought back in a low ponytail braid, brown eyes to match, large breasts, powerful looking muscles and perfect hourglass figure. They have never seen this stunner of a student before but she is wearing the school’s uniform.

“My name is Kimiko Tachibana! And I am here for the match that was promised!!” Kimiko proclaims as she puts her fists up and takes a step forward.

“KIMIKO TACHIBANA!?!?” They all shout in unison.

“No way!! You can’t be Kimiko Tachibana! That’s the name of the mouse!! No. There is no way!?!” Sawamura stammers.

“You said to train her for a month in preparation. And we did.” Kenji retorts.

“No… it… can’t be… you can’t be her!!”

“Let’s just say they helped me get one hell of a long-needed growth spurt during break.” Kimiko replies. “Now, shall we begin this fight?”

Sawamura charges at Kimiko. He swings wildly at her. She dodges his swings and lands a few of her own. He starts trying to take potshots at her. She punches him with a right straight to the face. She gets him into the old one-two. Sawamura kicks his leg and catches hers. She is caught off balance and begins to fall. Sawamura starts to lead into starting a barrage of punches. She touches the ground and pivots on her hand kicking him in the face with her strong legs. Sawamura is knocked back. Kimiko jumps back up and grabs him by the shirt. She tosses him over her left shoulder. He lands with a loud thud. He starts getting up off the ground.

“How does it feel to finally have someone who is stronger than you?”

“RRAAAAHHHHH!!!”

Sawamura rushes towards Kimiko. She pulls back her hands cupped. They start glowing.

“Huh?! What is she doing?!”

“I don’t know?! Where is that light coming from?!”

Sawamura stops in his tracks starting to feel afraid all of the sudden.

“Screaming…”

Sawamura takes a step back watching as the ball of ki forms.

“Spirit…”

Sawamura starts running away as the ball of energy grows brighter and larger.

“BULLET!!!!!!!!!”

Kimiko pushes her hands forward and unleashes the attack. It flies through the air at its target.

“AAAAHHHHHHHHHHHHHH!!!”

Sawamura screams as he is hit by the attack.

After the dust clears and the light fades. Sawamura stands there looking as if he just came out of a fire, falls forward and collapses.

“YES!!” Kimiko pumps her fist in the air causing her breasts to bounce.

The entire Science club shouts for joy.

“BOSS!!!!” Every single one of the MMA club members rush to Sawamura’s side.

“Thank you so much Kimiko!” One of the Science club members shouts.

“You overcame those astronomical odd that were against you?! You are like an angel!” Another adds.

Kimiko walks over to Sawamura and helps him up.

“Hey… that. That was pretty good. If you are still interested in joining…” He starts.

“No, I don’t think so.”

“Why not!? That was freaking awesome!! We would be unstoppable with you and Sawamura!!” One of the MMA members chime in.

“Exactly.  I’m going to start my own club. One that anyone who has a desire to fight and also a desire for justice can join.” Kimiko proclaims.

“And we will fight to keep ruffians like you under order!” She shouts punching her fist out towards them.

“I will call it the Athena club. After the Greek Goddess of Justice. Right Kenji?”

“Correct Kimiko.”

Kimiko walks over to Kenji and gives him a hug. Everyone else is too busy celebrating.

“Thank you for everything! If it wasn’t for you and your sister…”

“No thank you Kimiko. You helped me, the club member, and my sister just by being you.”

Kimiko gives Kenji a big kiss on the lips. She pulls back and he still stands there motionless with his glasses ajar.

“I’ve been wanting to do that for a while now. That was my first.”

Kenji still stands there motionless.

“Hehehe… Sorry Chieko, I think I broke him…” Kimiko giggles out loud.
