After the defeat of Evolto, a success of a new world and defeating the Blood Tribe. A young man who has short black hair neatly combed down except for the one that has a spike, wearing a red and blue striped pajamas.
"Sento, Ban! Wake up!" a voice called. the spiked hair guy named Sento woke up. He slowly opened his eyes and sat on the bed. He rolled his eyes and was about to get off on the bed until...he fell down.
Clang!
Sento fall down, face plant style, he struggles to stand up until he finally stood up while wobbling around and eyes are closed. He was about to go into the door until... he looks at the mirror. His eyes shot wide open, he quickly looked at his hands then himself.
"AAAAAAAHHHHHHHH!" he screamed before he puts his hands on his head. Even outside of his house, birds began to fly away from the house.
Unknown Location.
Red alarms began to activate, then woman who has long dark blue hair and brown eyed. She also wears glasses and often wears a purple shirt and a lab coat is running from a futuristic like tunnel while carrying a case. She looked back and began to run towards the exit. After that, she is...ON THE LAKE?! Yep. A lake. She ran up a hill in a few moments and stopped beside a nearby tree trying to get some air. She leaned back on the tree and looked at the case.
"Professor..." she sighed, she looked to her right and saw a few men wearing black suits and shades, that was only a meter from her, was looking for her.
"Find her?" asked the first man, as they are still looking around.
"Where the heck is she?"
The woman jumped and slide down on a muddy slope. The men ran from her previous spot.
"I will deliver this no matter what happens, Professor." said the woman before she looked down to the case she is holding.
Unknown Location.
Inside a command center. (A/N: If I'm right.) A man who has amber eyes and long, auburn hair, wearing a formal business attire with a red tie and a cape is standing there.
"Sorry, we've lost sight of the runaway!" reported the voice who is a part of finding the escaped woman.
"What should we do, Yagami-san?" the man behind the commander known as Yagami "If this gets out to the public, we'll be in big trouble!"
"I know that!." responded Yagami before looking back to the man "Mobilize all the agents and recover it at all cost" ordered Yagami, then he growled.
Back to Sento.
Sento POV.
OH MY INTEGER, HOW THE HECK DID I TURNED INTO A TEEN?! Calm down Sento... All I have to do is... tag along on this new world? I'll try. All I know is that I was resting at the cafe after Banjou and I defeated those Blood Tribe guys.
After I screamed, a voice groaned. I looked back to the bed, which was a double decker bed, and saw a boy with curly, brown hair, dark hazel eyes, and thick eyebrows. He wears an all blue pajamas. He woke up and rubbed his left eye using his right arm, he looked back at me.
"Geez, Sento. I was having a good dream of LBX's." LBX? What the heck is that?
"Umm... gomen?" I apologized, the kid nod.
"Sento! Ban! Wake up!" the voice of a female called us and...wait. How the heck did she know my name?!
"Looks like Okaasan's calling us." said the kid as he get off of his bed and went to the door "Come on, bro!" BRO?! IS HE MY BROTHER?!
I stuttered and nod. I also went to the door and head down stairs with him.
Few minutes later.
Time skip already?! Sorry dude. I got no more ideas. WHAT?! DUDE! *sigh* fine...
Now the kid and I are running. I wear my long sleeved white/blue shirt, blue jeans, with my good old mismatched high top sneakers, Red on the left foot and Blue on the right, a red and blue mixed shoulder bag with 'LBX' . While the kid wears an orange and blue jacket with a heart-struck cupid-theme logo on the back, baggy blue pants and a pair of red sneakers. He also carries a white shoulder bag with an 'LBX' on it. We stopped at a crossing. I was just standing there, while the kid is still jugging like he was still in a hurry. The traffic light became red, then the kid quickly ran. Wait.
"OI! MATTE!" I called back to him, I started to run towards him as well. If only I have my Rabbit Fullbottle...speaking of Fullbottles...WHERE THE HECK ARE THEY?!
Both of us entered a place called 'Pacifica Shopping District'. Both of us ran passed a couple of buildings, then we climbed the stairs.
After we climbed the stairs, we entered a store named 'Kitajima Model Shop'.
"Sorry we're late!" called the kid, and he nearly tripped "Let's do it!"
"Ban!" a girl who has has short, lavender hair and dark, violet eyes. In original series she usually wears a pale pink winter-like sweater with two white pom-poms, pink short skirt, white long socks reaching over her knees, black Mary Jane shoes and earmuffs, scold him and she looked back at me and she began to blush. Wait. Blush? "Sento..." she muttered my name, then she shakes her head.
"Why are you two late?" she asked us.
"What were you two doing?" asked a boy who is about our age, who has kinky, ginger hair tied to the back as a ponytail, and has dark, cerulean eyes. He wears a baby blue jacket, a white dress shirt with its collar popped and red tie, a pair of black pants and black dress shoes.
"Ask the kid who went to the bookstore." I answered.
"Well he's right." Ban said as he unzipped his bag "This week's LBX Magazine just came out." he took out a magazine and showed it to them "Just like Sento said, we went to the bookstore."
"Shoot, I just remembered it came out today!" remembered the boy.
"Ban, Sento, welcome in!" greeted a blonde hair woman covered with a red headband, and wears a crop-top, followed a man who has light brown spiky hair and brown eyes. He also has a light brown beard and also has tanned skin, while carrying two boxes.
"You two are late today." said the man.
"Owner, Saki-san, kon'nichiwa!" greeted Ban towards them.
"Ban, Sento, Ami, Kazu, come over here." called the Owner, just like Ban called him "I've got something interesting to show you."
We went to the counter, then the owner just landed the two boxes. The first one is...A ROBOTIC ACHILLES?!
"Achilles!" said Ban, then Kazu, if I am correct, opened the box revealing to be... "WHOA!" just the frame.
"A white LBX, this looks sweet!" complimented Kazu.
"What a nice design!" commented Ami.
"It's only for the armor frame, huh..."
"You can't use it unless you have a Core Skeleton." said Ban "Made by Tiny Orbit." 'Tiny Orbit'? That's a company?
"But this wasn't mentioned in this week's LBX Magazine." Ban said as he looked back to the Magazine he bought.
"Yeah." said Owner as he and Saki-san looked down to the frame "The wholesale seller said this was a new model, but it wasn't in any of the catalogs."
"So does that mean Achilles is super rare?" I asked Owner.
"Wow! I want it!" Ban cheered.
"No way." denied Kazu as he looked back to Ban "It's not like you have the money for it, and your mom won't let you and Sento play with an LBX anyway, right?" Wait I do? And Ban sighed in defeat.
"That's true... But I'll get one soon enough, just watch!"
"I'll be crossing my fingers for ya."
"Umm, Owner? What's that box under the Achilles frame?" I asked, and yes, I noticed the box.
"Why don't you look at it for yourself, Sento?" Oh damn right I will! I put the box on the side. It reveals to be...BUILD?! NANI?! HOW THE HECK DID IT GOT HERE?!
"EEEEEHHHHHH?! B-BUILD?!" I gawked and just looked at the box art. It reveals to be Build on RabbitTank form holding my invention...THE DRILL CRUSHER! In sword form!
"So you know Build, excellent, Sento!" cheered Owner. Ban, Kazu and Ami walked right next to me and take a peak to Build.
"Woah! Look at it! It looks cool! An LBX that has an animal and item motif!" Kazu complimented and...OF COURSE IT IS!
"Sugoi~! The color suits it!" Why thank you Ami-chan!
"Build looks awesome! Oh! And look at that sword it's wielding!" IT'S MY BEST WEAPON OF ALL TIME! Well, but the FullBottle Buster is the best. For now.
"You can open it Sento." OH YEAH I WILL! I opened the box and saw...MY TWO FULLBOTTLES! RABBIT AND TANK FULLBOTTLES!
"Wait...why are there two bottles?" Kazu asked.
"It says here in the magazine that Build is a special LBX...WHOA! IT CAN CHANGE FORMS AS WELL!" informed Ban, then he showed us the pics of Build of the Best Match and Trial forms.
"That's true, Ban. So Build can change forms, the LBX itself has a special CCM." agreed Owner.
"A special CCM?" all of us (minus Ban who is still reading the magazine) repeated in unison.
"You mean this CCM, Owner?" Ban asked before he showed us the picture of...MY BUILD PHONE! And the additional is that the Build Driver is on the top of it.
"Yep! That special CCM." OH MY GOD THEY EVEN MAKE IT MORE HIDEOUS!
Ban began to stretch his arm "Now that's over with, how about we start playing LBX's?" suggested Ban. To be honest, I don't even know how to play an LBX?
"Sure!" Kazu agreed. Both boys went to a modified table. Owner-san gave Ban his LBX while Kazu placed his in the table, Ban did the same of course. I walked next to Ami, who blushed again for no reason.
Ban POV.
Yosha! Now it's my turn! I am using Kojirou-san's Gladiator while Kazu is using Warrior.
"We'll follow the official rules and battle in the fortified box, got it?" Owner-san explained "We can't have these LBXs be seen as dangerous and get the sales canceled, or else we won't have anymore business to run."
"Then we'll go with the Standard Regulation." continued Ami.
"No destruction for the finish." finished Sento while he is reading the manual book again.
"Roger." said Kazu "Ban, I'll be taking today's win!"
"I won't back down either!" I replied "Here I go...Battle start!"
End POV.
Outside Pacifica Shopping District.
Three agents are running past a store, but they didn't notice that the woman from before is hiding. Then she ran away.
Blue Cats Coffee.
A man who has has purple, spiky hair. He wears a He wears a red apron, vest, and dress pants and shades. Who is answering his phone.
"I see. Understood." said the bartender "Contact me again if you get anymore news."
"Was that from the one you sent in to infiltrate?" asked a blonde haired man with a serious face, wearing a grey suit.
"Yeah. The two new LBX model they were developing was stolen from the company." replied the bartender.
"Two new LBX model? Is it those two?" asked the man to the bartender.
"Likely."
"How could this happen..." said the man before looking down "This'll stir up a lot of trouble."
"But this could be our chance." added the bartender, then the man looked at him "If we can get our hands on it," the bartender looked to the man "it might be our trump card to run down the Innovators."
"A trump card to run them down..." repeated the man.
"We have to find a way to get those LBXs."
Back at Kintajima Model Shop.
Kazu's Warrior crashed on a rock, blue aura glowed at him then it 'explode'.
"Yes, I won!" cheered Ban on his victory.
"Geez..." sighed Kazu "Like always, you're really strong even though you're just using someone's LBX."
"Since it's one of mine, it gets the best tuning care, after all." said Kojirou. "Yep, yep." agreed his wife.
"That makes it sound like it's all thanks to the machine. I had an actual strategy for my fight, you know."
"Then you should get your own machine already, Ban." said Sento before closing the manual and returned it to Kojirou.
"Yep." agreed Ami.
"You too, Sento! I thought we're brothers?! Okaasan didn't want us to get our own LBXs you know!" recalled Ban to his 'brother'.
"I am obeying Okaasan's orders. Not like you always wantng to get an LBX." recalled Sento if that's right.
"Easier than done..." sighed Ban in defeat. Then all four went towards the door.
"See ya. I've got a place I need to check out." said Kazu.
"Saiyonara Ban and Sento!" said Ami, then both teens went off to their perspective destination.
"Ami see you tomorrow!" Ban and Sento said in unison.
Misora Jr. High School 2.
Students are walking away from school, the woman from before is there looking at the school. She looked to a fellow student.
"Excuse me." she said to the student who was about to walk home "Do you know someone Yamano Ban and Yamano Sento?"
"Yamano Ban and Yamano Sento?"
The Command Center.
"You haven't found it yet?" asked Yagami to one of the worker.
"We have our agents in every area in Misora Town currently." responded a female worker "They should be able to find it soon."
"Recover it at all costs. At all cost!"
In another location, near the bridge.
Ban and Sento are walking towards their home.
"That LBX was so cool." recalled Ban.
"Achilles or Build?" Sento asked.
"Achilles." answered Ban, as he sighed and looked up "I want one like that..."
"Too bad. Okaasan didn't want us to get an LBX remember?" recalled Sento.
"You're right." Ban admitted. He looked to the plain grassfield, he run towards it and lied down. Sento just walked towards it and sat.
Flashback.
8 years ago.
A young Ban and Sento are taking a glance at their father who has brown, messy hair and is akin to an older Ban. He is typically seen wearing glasses, a blue shirt and a bandana tied on his fore head. He is currently making a little robot skeleton.
"Tousan, what's that?" asked the young Ban and Sento.
"This is called an LBX." answered their father.
"LBX?" repeated the 'brothers'.
"Yeah. It's a small robot that fight like a hero. It can take down bigger enemies too."
"Really? Awesome!" young Ban and Sento beamed. They ran to the side and pointed to the LBX.
"Tousan! I want this!" both 'brothers' said in unison.
"Oh, you two do?" asked their father as he looked back at his prototype "But I can't give you two this one."
"Why not?" asked young Ban.
"Is it because that it's only one?" asked young Sento.
"It's not that because this is only one. It's because it's still a prototype, so it's not the final product. But when you two get older, this will be ready." answered their father before he looked back to his prototype "Wait for it, you two."
(A/N: I will skip where Ban here will narrate the flashback.)
Present.
Ban sit up and looked at the sky. Both siblings didn't notice the woman who's carrying the case found them.
"I found them."
"Yamano Ban-kun and Sento-kun!" the woman called the boys as she ran toward them. They looked at her.
"You two are Yamano Ban and Sento, right? I've been looking for you two." she suddenly grabbed their hands and ran towards under the bridge.
"Wait a sec, who are you?" asked Sento, then they crouched under the bridge.
"I don't have time." denied the woman "Listen to me carefully." the brothers are now dumbfounded. The woman grabbed the case and showed it to them "I came to give you two this."
"This is the key for saving the world."
"For crying out loud, where did she go?" a female voice asked. The woman walked slowly and looked towards on three agents who are wearing masks.
"Boss, are you getting hungry?" asked a male voice.
"I'm so beat." said another one.
"Stop fooling around!"
"This isn't good.." muttered the woman.
"Show some manliness!" said the female masked agent.
"What's going on?" asked Sento.
"And how do you know our names?" added Ban. The woman looked back to them and walked close to them.
"Boys. Inside this is both the hope and despair of mankind. This must never be used for the wrong purposes." she then gave it to Sento "I'm entrusting this to you. Don't ever give it to anyone else."
Sento and Ban nod, the woman looked back to the agents.
"I can't tell you details right now." she looked back to the Yamano siblings "But that's something that you two should have."
"But..." Ban was about to say something.
"I'll get their attention, so get away while you can." informed the woman "Got it?" then she ran away.
"Hey! Wait a sec!" Both siblings called out for her, but it's too late.
The chubby agent looked behind him and saw the woman "There she is!"
"Don't let her get away!" ordered the female agent.
"What the heck was that?" asked Ban.
"I don't know...but let's do what she tells u, okay?" Sento replied. Ban looked at him and nod. Then they ran away as well.
While the agent are chasing after the woman. The female agent looked to the boys who are running as well, she noticed something...it's the case.
"That's!" she said.
Yamano Residents.
Ban opened the lights, and Sento lay the case on the table.
"Okaasan, are you home?" asked Ban "Is she out?" Ban said then he walked near to Sento.
Outside on their house is the three agents hiding in the bushes.
"Boss, let's bust in and grab it." suggested the fat agent.
"Wait! Don't rush in." denied the female agent.
"Boss, I've been wondering, but what's inside that case anyway?" asked the blue haired agent.
"I haven't been informed."
"Eh?!" both agents gawked.
"Be quit! Well, it's gotta be something big. It's got a Death Lock Trap attached to it, after all."
"Death Lock?!" repeated the agents "I've heard of that." said the blue haired one "If an authorized person touches it, a poisonous dart will shoot out..."
"And you'll be a goner..." finished the female agent.
"Scary!" both agents shouted.
Inside the house. Ban and Sento are just looking at it.
"What's inside this anyway?" asked Ban. Then a flashback is being recalled.
"Inside this is both the hope and despair of mankind." Ban and Sento just looked at the case "But that's something that you two should have."
"Well, whatever. Let's just open it." said Sento. Ban nod, he opened the case and it reveals to be...two LBXs. One is blue that has an X on it's chest while the other on is grey that has two plain antennas on it, also there's an X on the chest. Both LBXs has the same design.
"An LBX?" asked Sento.
"AX-00." Ban repeated on the words he read on top of the LBX. Both Sento and Ban grabbed the LBX and looked at it.
"Who's the maker though?" asked Ban while Sento shrugged.
"Commencing user certification." a female robotic voice said to both LBXs. The X on the chest glowed then a scanning beam began to scan their faces.
"Confirming user." then it finished scanning their faces.
"Certification complete. You have permission to proceed."
"The poison dart's not coming." said the blue haired agent.
"Is it bugged?" asked the chubby.
"So two LBXs are inside." said the blond "Okay, let's head in."
"Roger." both agent replied, as they took out their CCMs and pressed the buttons.
Then three LBXs jumped out from there and landed. The three LBXs are the same, all of them has one red eye, a light green tactical shield same as their armor frames. Two are holding axes while the other is holding a gun.
The LBXs jumped out to the side and entered an open window leading to the kitchen.
Back inside is Ban and Sento looking at the LBX. In front of Ban is the blue one holding a metal bo staff while Sento has the grey wielding the short sword.
"Why did she want to give this to us?" asked Sento still looking at the LBX while holding the CCM from the magazine, and the manual.
"I don't know. Maybe this is the new model!" answered Ban holding his own CCM and manual "But will it move?"
Then the LBX from outside nearly shoot Ban, Sento and the LBXs in front of them. The two LBXs lied down on the table. The armed LBX looked to the two lying LBX.
"What's this LBX doing here?" asked Ban. The LBX looked back to the siblings, it raised the gun and shoot it on different directions. Ban and Sento quickly react and hid behind the couch.
"I think, we're in trouble." said Ban.
"We're already in trouble." corrected Sento. Then the shooting stop. Sento and Ban took a peak to the LBX, then two more LBXs appeared.
"They're after those LBXs." said Ban.
"Let's fight them!" said Sento, both boys looked towards the two CCMs on the couch. Both boys grabbed it and hid behind the couch again. Ban and Sento opened the CCMs and pressed the buttons.
"Please move!" hoped both boys.
Then the two LBXs eyes glowed and moved. They sat up and looked around.
"Yosh!" cheered Sento. The LBX with the axe was about to slash the two, but the two AX-00 grabbed their weapons and jumped out and landed on the other side. The LBX aimed to the two and shoots the both, but luckily they dodged it.
"Woah! It's got really good response time." beamed Sento and Ban. The LBX wielding axes landed on top of the couch and looked around. The two AX-00s are hiding behind the vase.
"Attack, attack..." muttered both boys as they are trying to find the attack button from the manual they are reading. The two wielding axe LBX landed on the ground and they to walk to the vase, but the other one walked to the other side.
"It must be this one!" both boys assured. The LBXs found Ban and Sento's LBXs, they tried to slash it, but the two AX-00 quickly jumped out of the way. They landed on top of the vase and jumped again to prevent being hit from the bullets. The LBX holding the gun aimed to them and shoot again, but the two AX-00s jumped again, jumped to the couch, and hid behind it. The gun wielding LBX walked to the edge and looked down, but unexpectedly, Ban and Sento's LBX jumped up and readied to attack the gun wielder.
"IKE!" both boys shouted. Ban struck his metal bo staff on the chest while Sento struck his on the head. They unstuck their weapons on the LBX and jumped out, then it exploded.
"This guy's awesome/ Sugoi!" both boys beamed.
Outside the house. The blue haired agent just looked at the two boys and gawked.
"Th-They got me!" gawked the blue haired agent.
"They beat a Deqoo in one hit!" agreed the chubby.
"What the heck are you doing!" scold the female agent to the blue haired.
Back inside.
"Two more." said Ban. Ban's LBX fought the first axe wielder while Sento fought the other axe wielder. All LBXs clashed their weapons. Sento's LBX slashed his opponent and kicked him back, Ban's LBX did the same to his opponent. Sento's LBX went to Ban to help him out.
"We're not beginners, you know." said Ban.
'Actually, I am a beginner.' said Sento in his mind.
"But we can do this!"
"He's really good!" commented the chubby outside the house.
"It must be because of the machine." said the female agent.
"We'll attack them together this time, got it?" said the female to the chubby.
"Roger!"
"Prepare yourselves!"
"Boys!"
Both of their respective LBXs began to charge to them. Ban and Sento did the same. Then they slashed each other. Ban and Sento stopped while the two LBXs sides are damaged causing them to explode.
"Yatta!" cheered the siblings before they revealed themselves from their hiding spots.
Outside the three losed agents just looked at him.
"They're too strong." gawked the chubby.
"We've been wiped out." agreed the blue haired.
"Quiet, I know!" snapped the female before looking back to them and looked back to Ban and Sento cheering "Those LBXs... Something's weird with it."
"We're retreating." commanded the female, then they crouched away.
Back inside is Ban and Sento sighed in relief.
"What was all that just know?" asked both siblings as they looked around. They looked the whole area with gasps. The living room is a...
"EEHHH?! THIS IS A MESS!" both cried then sighed. The boys didn't notice that someone opened the door.
"Tadaima!" their mother said causing Sento and Ban to panic.
"Boys, you're back? Then did you take a bath-" their mother was about to finish but she stopped and looked at the messed up living room
"Oh, Okaasan, there's a big reason for all this..." excused Sento. Then they shake their heads behind. Their mother looked to the two and saw their CCMs.
"Sento, Ban, you two got an LBX?"
"Okaasan, um, this is..." Ban tried to reason before looking down.
"It's fine, be sure you two clean this up." said their mother in a calm tone. She opened the door beside her, went inside and closed it. Ban and Sento sighed in relief.
Their mother is still there standing 'Boys... The day has finally come.' said their mother in her head.
Back at the Command Center.
Yagami is just looking at the blueprint like image of the two AX-00.
"AX-00s has been activated." reported the female worker "The designated users was certified with it."
"The deignated users?" repreated Yagami "Who are they?"
"The registered names states..." then texts of the name appeared to be 'Yamano Ban' and 'Yamano Sento'.
"Yamano Ban and Yamano Sento."
"Yamano Ban? Yamano Sento?" repeated Yagami "I see. So that's how it is." he looked behind "So you're the one pulling the strings behind this incident!"
He scolded to a scientist whose hands are on his pockets and his face is hidden in the shadows "Why are you doing this?" asked Yagami to the scientist "Are you trying to lead the world to destruction? Professor!"
