Disclaimer: I do not own Gundam Build Fighters and some characters may act or be different than in the Anime

Heads up you guys all know my "I stand on the feminists' side" so once again this is a gender bend story with Sei Iori as a girl (Saeko), Kousaka is a guy and basically Rinko Iori approving of a future relationship with Ayla and pushing her towards Reiji as well… Ha! Didn't see that coming now did you, also before I forget Sei will be using some gundams I created in my mind, so sorry if my gundams suck, but my story so stuff it or don't read it and imagine Strike Build or something, but don't worry I will still use Strike build so instead of the Build MK-II, it'll be my special creation/s. I'm going to be giving Sei something akin to Psyqualia from Cardfight!Vanguard, so don't be surprised if you see gundam speech. Anyways on with the story, Gyan gyan guy on with your flirty fighting now get out there and be the annoying prick you were in the anime

Chapter 1: the confrontation, the Gyan addict versus Saeko the builder

In the Iori hobby shop standing behind the counter was a girl around the age of 14, with blue hair reaching the small of her back, she was around 5'4" in height. That girl was Saeko Iori and she was currently reading a book, while looking over the shop

"Welcome to the Iori hobby shop, how may we help you today" Saeko said with a smile as a young boy and his father entered the store

"Impressive, all these Gunpla are very well built" the Father of the boy stated as he studied the model figurines

"Tou-san, tou-san can I get that one" the boy said in excitement while pointing at the Wing Gundam

"That's a good choice, the XXXG-01W Wing Gundam is one of the few Gunpla with the transformation ability, while it would be hard to master, if you master this gundam… there will be many doors open to you as a Gunpla fighter" Saeko said in a very warm voice that made both of her customers feel at home

"Tou-san, Tou-san can I get it, can I, can I" the boy pleaded (don't know what a child would say please don't judge me for this although you probably already judge me for making so many gender bender stories)

"Of course Keisuke and if you build them as well as these, who knows how many championships you'll win" the man said to Keisuke

"Thank you for the complement" Saeko said and bowed a little

"Huh? Complement? Wait! Did you built all of these models!?" the Man exclaimed in shock receiving a nod from Saeko

"Yes… I built these models, however they're more for display than anything else" Saeko said and tucked a stray strand of hair behind her ear

"cooool, onee-chan, onee-chan please teach me how to build Gunpla as good as you do, please" Keisuke begged as he latched onto Saeko's leg

"Okay, let me just set up the building table and we can start" Saeko said with a smile as she set up the table and helped Keisuke build his new XXXG-01W Wing Gundam

"Well now, if it isn't Iori-Chan" a voice suddenly said as her customers finished building their gunpla

"Good morning Susumu Sazaki-san, How may I help you today" Saeko greeted with a more forced smile but still relatively warm voice

"How about you become my girlfriend, let me pilot your gunpla and a kiss" Susumu suggested earning an exasperated sigh from Saeko

"No thank you Sazaki-san, you're play style is too rough for me to let you use my Gunpla, and you're not my type" Saeko explained getting a eye twitch from Susumu

"How about I show you that I wasn't asking, Saeko-chan let's fight, let's gunpla battle!" Susumu stated and held out his YMS-15SS Gyan

"Fine, Let's gunpla battle" Saeko exclaimed as she opened the display case and brought out Wing Gundam

"Please set your GP base" the computer/table announced as Saeko and Susumu placed a rectangular device in a open slot on opposite sides of the table

"Initiating Plavsky particle dispersal" the computer/table announced as particles flew around in the radius of the hexagonal table

"Field 2: desert" the computer/table announced as the particles formed a sandy terrain with rocky spires randomly placed about the field

"Please set your Gunpla" the computer/table requested as both Saeko and Susumu placed their gunplas onto their GP bases, while the father son duo cheered from the background

"Iori Saeko, Wing gundam… launching" Saeko announced as more people entered the shop and were now viewing the gunpla battle

"Sazaki Susumu, Gyan… deploying, now I'll show you how skilled I am, by the end of this you'll be begging me to pilot your gunpla and be my girlfriend" Susumu stated

Speeding towards the Gyan, the Wing gundam brought out its beam saber and shifted to the left, narrowly avoiding the beam that the Gyan shot and continued its path strait for the Gyan

The Gyan fired a barrage of beams hoping to hit its opponent, but the Wing Gundam kept shifting narrowly avoiding the beams, until it jumped up and transformed into Bird Mode, rocketing into the air at unbelievable speeds avoiding all the beams that were shot at it

'Impossible, no one has ever managed to dodge all of my attacks before' Susumu thought in shock as his barrage grew in intensity

Sensing the change in the rate of fire, Saeko made Wing gundam dive bomb towards Gyan while also avoiding the beams

Getting in close, Wing gundam shifted again with its beam saber deflecting every beam that was aimed at it

'Nooo!' Susumu thought as Wing gundam was now so close to Gyan that Saeko was able to make Wing Gundam slice off Gyan's left arm, also the only arm that had a shield

The Wing gundam blurred around the Gyan, as the injured mobile suit desperately shot everywhere to try and make up for its lost defense, eventually Wing Gundam managed to close the gap and slice off the right arm as well, leaving the Gyan defenseless

Wing Gundam aimed its Beam Saber towards the Gyan's chest, Saeko's voice came out of the Gunpla "surrender now Sazaki-san, it's over" Saeko declared, making Susumu slump in defeat and press the concede button

"Received concede confirmation, battle ended winner Saeko Iori" the computer/table announced and the gathered crowd cheered at the battle that ended

Walking over to the still slumped Susumu, Saeko helped him stand on both of his feet and gently gathered both gunplas, told him to wait until she was done serving the other customers, greatly confusing Susumu before returning Wing Gundam onto the display cabinet and serving the other customers then helping them build their chosen gunplas, before fixing Gyan and giving him back to Susumu

"Please take better care of your Gyan… Sazaki-san and please stop by again" Saeko said to the awestruck Susumu before ushering him out of the store

'I will get you to marry me Saeko Iori… that is a promise' Susumu swore before regaining his arrogant disposition and walking away with a bruised ego but stronger feelings for the Iori girl

As Rinko Iori returned to the hobby store with all the ingredients she needed for that nights dinner, Saeko Iori went out to take a stroll around town and stopped at the park where a red headed boy bumped into her, causing her to fall

"Gah! Hey! Watch where you're going" the redheaded stranger yelled at her while eating his bread

"Ooww" Saeko moaned in pain on the floor before getting up on shaky legs

"I finally got you, you little thief" the local baker exclaimed as he grabbed the redheads' arm

"Hey! Don't walk up to people calling them thieves" the redhead exclaimed

"How can you say that!? You stole bread from my store!" the baker exclaimed

"Huh! You mean this?" the redhead asked as he looked at the bread he was holding "This was left outside the store. So I took it, that's all." The redhead explained

'What! Who is this boy, doesn't he know anything' Saeko thought to herself as she watched the scene

"It's called storefront sales! I can't have you taking them without paying!" the baker yelled

"Then put them somewhere safe!" the redhead yelled back, attracting the attention of the passing bystanders who were gathering around, forming a crowd

"What did you say!? How dare you be so brazen! I'll take you to the police!" the baker yelled

"What!?" the redhead yelled back and grappled with the baker

"Please wait a second!" Saeko exclaimed as she forced her body between the two men, successfully separating them and catching both of their attentions

"Huh? You're Mr. Iori's…" the baker started

"I don't think he meant anything bad, so I'll pay for it this time" Saeko interrupted him, causing the redhead to stare at her

Groaning in confusion, the baker relented and let Saeko pay for the bread before leaving, bringing with him the crowd of people that were watching the dispute

Near the play grounds

"Here" Saeko said as she handed the redhead a bottle of Soda

"Thanks" the redhead said as he took the bottle from her before opening it and taking a few gulps and opening his eyes and spitting some of the drink out of his mouth "What is this!? It felt weird in my mouth" the redhead said and pointed at his mouth for emphasis

"Huh! Haven't you had soda before?" Saeko questioned him with confusion dancing in her eyes

"But it sure tastes good" the redhead said as if Saeko hadn't asked him a question and took a big gulp of the beverage "Cool! It's refreshing" the red head exclaimed, making Sei smile at his childlike personality

"Guess I've caused you trouble and sorry for bumping into you a while ago" The redhead said

"It's not your fault. You just came from overseas and don't know Japan well, right? We should help others when their in need" Saeko consoled him, making him stare at her

Standing up "I'll pay you back for this. That's a promise" the redhead declared

"Don't worry about it" Saeko said

"I can't do that. It's a matter of family dignity. Our honor will be harmed" the redhead explained, making Saeko smile a little at him

Getting a light blue crystal the size of a marble and holding it in front of him, he said "I'll give you this"

"What is it? A gem!? I can't take something so expensive" Saeko exclaimed while holding her hands in front of her face, blocking her vision of the crystal-like item

"It's just a rock" the redhead explained and gave her the colored almost transparent "rock"

"Huh?" Saeko questioned as she scrutinized the "rock"

"And you are…?" the redhead questioned

"I'm Saeko, Iori Saeko" (if I have to tell you who said this, I will hunt you down, teach you about analyzing, and then I will kill you slowly and painfully)

"I'm Reiji" (again if I have to tell you who this is, I will kill you)

"Reiji" Saeko said with a small smile on her face

"Sei, if you're ever in trouble, just make a wish on that rock. At any time, in any situation, I'll come running. I'll handle any sort of trouble. That's a promise I swear" Reiji declared with a smile

"Hmm… you're like some sort of superhero…" Saeko stated as she closed her eyes only to open them and see nothing "Huh? Where'd he go?" Saeko asked no one in particular while looking around

In school the following morning

Scrutinizing the supposed "rock" that Reiji gave her, Saeko was still a little unbelieving that the blue orb in her hand was just a rock.

"It looks beautiful" a voice said, snapping Saeko out of her trancelike state before looking at the source of the voice "the gem you're holding, it's beautiful" her seatmate said as he looked at the gem she was holding

"It's just a rock" Saeko said as she gently laid the "rock" on the table "Do you think it's silly, Kousaka-kun?" Saeko asked as she stared at Kousaka

"What is?" Kousaka questioned as he looked at Saeko, who was just staring at the rock in mild interest while her hands rested on her lap

The next morning at the Iori hobby shop

Saeko connected the final piece to her master piece, a variation of the GAT-X105 Strike Gundam and smiled at it

"Kaa-san I've finally finished it, my unique gunpla that I'll use for the Gunpla Battle Championship (GPC), the Build Strike. It's my own original gundam, based on the GAT-X105 Strike Gundam" Saeko said as she placed her gundam on the front desk to show her mother

"That sounds wonderful" Rinko said as her daughter finished explaining "I don't know as much about Gunpla as you do, but… It has the same kind of aura as the models your Tou-san built" Rinko said making her daughter glow in excitement and happiness

"You think so? It's still far from complete though, having no other weaponry besides its beam sabers" Saeko explained in the still dazed happy state

"Yes, I do" Rinko told her "baby girl" in happiness as well

"Huh?" Saeko exclaimed as she turned around, having heard the shop entrance ping signifying a customer's presence"Oh! Good morning Sazaki-san"

"Welcome Susumu-kun" Rinko greeted from the corner

"That's your new model isn't it, so beautifully made just right for me to operate" Susumu stated as he studied the Build Strike gundam with a glint in his eyes

"Um… I'm sorry Sazaki-san, but I'll be using this gunpla in the GPC so you can't use it" Sei said as Susumu stared straight into her eyes, making Sei squirm a bit in discomfort

"Oh… then how about we battle my Gyan versus your Gundam and if you win, I'll stop asking you to let me pilot your Gunpla, however if I win you have to let me use your Gunpla and you have to become my girlfriend" Susumu offered with a smirk, making Rinko inwardly glare at the boy for wagering her daughter

'This opportunity is too good to pass up, but if I lose I don't just lose all the Gunpla I will make and have made, I'll also have to date Sazaki-san' Saeko thought with an unnoticeable shiver running through her body

'Do you doubt your capabilities? Have you no faith in the Gunpla you have made?' a voice asked Saeko, making her widen her eyes and slightly shift her eyes to see if anyone else heard 'Do not fear my voice, I have not come to harm you or your loved ones and not so loved ones' the voice explained

'Then who are you and why are you talking to me?' Saeko asked in her mind, not wanting to seem crazy to the people around her, who obviously couldn't hear the voice

'I am the voice of your Build Strike, my creator we, all of the Gunpla that you assembled have agreed that we would like to fight for you, just as Wing Gundam had' Build Strike said to her, causing Saeko to slightly widen her eyes 'Do not fear the results that have been laid in front of you, fear the results of the work you have accomplished. All of us believe in you… Saeko Iori, you are our mistress and we will do everything in our power to never fail you' Build Strike stated in her mind and as she briefly glimpsed at the Gunpla on display she saw all of their eye pieces glow lightly, as if too enforce the words spoken in her mind

'Alright then… thank you for believing in me, I'll try not to let all of you down' Saeko thought earning her a light laugh from Build Strike

'You don't have anything to prove, especially not to us… we'll fight for you Saeko Iori and maybe we could also be your confidant in anything at all, we gunpla do pride ourselves with being good listeners after all' Build Strike said and then went silent

"Okay Sazaki-san, you have yourself a deal" Saeko agreed getting a concerned expression from her mother

"Saeko-chan are you sure about this? After spending so much time building that Build Strike gunpla?" Rinko asked her daughter in worry especially since she would have to date someone she was clearly not interested in if she lost

"Don't worry about the things that could happen before you do something, think of the things that will happen after you do it. Kaa-san… it'll be fine trust me" Saeko replied while smiling at her mother's concern also stunning Rinko with her "hidden" wisdom

"Ok, I've heard enough! To make sure this match is fair, I'll be the referee" a stranger said

"Mr. Ral! Welcome, I apologize for not seeing you earlier" Saeko said and hurriedly bowed to emphasize her apology

"Hahaha… oh, don't think so much about it Saeko-chan, I accept your apology as well" Ral said gaining a very bashful personality when talking to Sei and Rinko, before going back into a serious mode

Bending a bit so he was at eye level with Susumu, Ral stared into his eyes, unnerving Susumu a little bit "Hmmm, you have good eyes, they're filled with confidence and ambition. You have guts, too. But nothing is guaranteed on the battlefield, boy." Ral said

"Welcome, Mr. Ral" Rinko greeted

"Rinko-san, excuse me for disturbing you" Ral replied in his bashful persona, making Susumu stare at him, while Saeko didn't notice anything wrong with his behavior considering he did that to her as well

"Please set you GP base" the computer/table announced as Saeko and Susumu set their GP bases on opposite ends on the table

"Initiating Plavsky Particle Dispersal" the computer/table announced as particle created the landscape

"Field 2: Desert" the computer/table announced as the familiar sandy terrain appeared

"Let's see your resolve, let's see how you do in your life and death situation" Ral announced from behind the glass

"Please set your Gunpla" the computer/table requested as Saeko and Susumu placed their Gunplas

"Saeko Iori, Build Strike Gundam… launching" Saeko stated as Build Strike launched

"Susumu Sazaki, Gyan… here I come, you'll be mine Saeko-chan" Susumu stated as Build Strike and Gyan met in the center of the battlefield

"I wonder how Saeko-chan will do in her first battle" Rinko wondered while Ral glimpsed at her before turning back towards the battle, both unaware of the crowd that was forming behind them 'Have you bit off more than you can chew Saeko-chan… only one way to find out' Ral thought to himself and paid even more attention to the fight

Build Strike immediately charged at the immobile Gyan unit and activated its beam saber

'Those moves… is Saeko-chan secretly a newtype, this is her first battle yet the movement suggests otherwise' Ral thought to himself with a look of awe on his face

Gyan started its relentless barrage of beams, shooting rapidly in the direction of the Build Strike

"That's not going to work on me!" Saeko stated as a beam passed through the Build Strike making Susumu smirk, until the Build Strike vanished slowly… fading from the area where the beam passed through outwards

'What!' everyone watching thought with wide eyes and stared in shock at the spectacle that happened in front of them

"I already told you, that won't work on me!" Saeko's voice penetrated the air, making the Gyan look upwards and raise his shield to block the beam saber, as the sword and shield collided, creating a shockwave that made the sand rush away from the clashing gunpla

Suddenly the Gyan's missile shield cracked from the force of the collision, sending Gyan onto its knee as it raised its shield higher

'What is this power!?' both Ral and Susumu thought in awe and wonder, while the gathered crowd cheered at the battle

Breaking away from the clash of strength, Build Strike kicked Gyan away, sending Gyan skidding across the field

'Weak… what a weak opponent' Saeko heard Build Strike comment in her mind

'Now, now… be nice Build Strike' Saeko thought trough the apparent telepathy link she had with her gunpla

'My apologies, my Mistress' the Build Strike replied, before going silent once more

Making Build Strike rush at its opponent with its beam saber at the ready and making a downward slash, unfortunately for Gyan… Susumu was still in shock, which resulted in its shield arm being sliced clean off, leaving no indication that there was ever an arm in the first place

Snapping out of his dazed state the moment his Gyan's arm was cut off, Susumu successfully maneuvered his Gyan away from its superior opponent

"That's useless…" Saeko said in a soft yet determined voice as Build Strike faded slightly but otherwise remained in a stationary position, however proving his theory wrong was the Build Strike who materialized behind Gyan and landed a vicious round house kick that sent Gyan skidding towards the faded Build Strike, who reared back its leg and landed a powerful kick to its mid section, sending Gyan back where it came, towards the other Build Strike whose leg was positioned for a devastating axe kick, that completely destroyed Gyan's right arm

"Give up Sazaki-san… it's over" Saeko stated through Build Strike

Slumping in defeat once again, Susumu once again pressed the concede button 'just how strong is she?' Susumu thought to himself as he gathered his Gyan and left the store, wanting Saeko even more than before

"Nice fight… Saeko" a familiar voice congratulated, making Saeko widen her eyes and spin on her heel to come face to face with Reiji

"Reiji-san!" Saeko exclaimed and received a smile in return, causing her to blush a little and divert her gaze towards the oh so interesting ground

"Hmmm… are you a friend of Saeko" Rinko asked as she saw Saeko's reaction and immediately gained a glint in her eyes

"Yo… I'm Reiji, me and Saeko met two days ago" Reiji explained

"Ehh… then why don't you eat dinner here, I'm sure Saeko-chan will be more than happy to cook for you" Rinko suggested

Upon hearing her mother's suggestion Saeko's head snapped up towards her mom with rosy red cheeks "Kaa-san!" Saeko whined in embarrassment

"Eehhh… Saeko can cook?!" Reiji exclaimed, receiving a nod from Rinko and a slightly weaker nod from Saeko

"Sugoi… you have to let me try your cooking Saeko" Reiji stated and grabbed Saeko's wrist, dragging her behind him as he raced up the stairs with Saeko fluttering in the wind behind him

"Aaahhhh… Reiji-kun! Slow down!" Saeko exclaimed with tears in her eyes as she tried to hold onto Reiji for dear life, not even noticing that she added kun to Reiji's name

"Hhhaaaa… the wonders of youth" Ral said as he smiled at the two

"I still have to attend to the customers, I'm sure Saeko will make a wonderful dinner for the three of us" Rinko said as she attended to the customers who watched the fight between Saeko and Susumu

The night

Rinko finally closed shop and went up the stairs to find the table filled with food; Carne de Porco à Alentejana (Portuguese pork dish), steak, mashed potatoes, rice, Sautéed Crab, Miso soup, sushi, Lemon Chicken, Rigatoni con la Pajata (Roman spaghetti dish) and Caesar salad. A lot of dishes she didn't even know her daughter knew how to make! What amazed her more was the fact that Saeko was still wearing her apron and standing beside Reiji as he ate with a furious blush on her face, while hugging a round serving tray to her chest and chewing her lip, not even the fact that there were ten other serving plates already in the sink or the fact that Reiji's eating habits were really bad were enough to catch her attention. Rinko smiled and took the seat across from Reiji and started her meal as well, eyes lighting up at the different tastes that assaulted her taste buds. Briefly glancing at Saeko's plate which she noticed was already used and cleaned, just drying on the plate rack

'she must've eaten quickly so that she could get clear the table of the empty plates' Rinko thought slightly amused at her daughter and continued eating 'one thing's for sure though Saeko is cooking dinner again' Rinko added as an after thought

After dinner and Reiji telling his story to both Saeko and Rinko

Both women were hugging each other for comfort while tears cascaded down their cheeks

"Reiji-kun… feel… feel free to st… s… stay here as long as you want" Rinko managed to get out through her tears with Saeko nodding along, making Reiji sweat drop at the scene

"Y…yu… you can s… st… st-tay in my room… I'll just… I'll just sleep with Kaa-san" Saeko managed before burying her face onto her mother's shoulder and releasing more tears (I don't know how to stutter nor do I know how people sound if they talk after crying… sorry)

Chapter 1 end

And this is how Reiji can to live with Saeko and Rinko Iori and whenever he would wake up early and check up on them, find both of them facing each other while hugging and lightly snoring
