Vol 1 Chapter 1 (1/2)

Part 1

“Kizuna, the test for today is this program”

A long haired female displayed the content for today’s experiment on the monitor

Kizuna nodded largely after confir that content

“I got it, okaa-san I’ll work hard too today”

“Right, you really are a good child Do your best”

It was a pure white experi There hisexperiments day by day

Those experiments were about the development of a neeapon called Heart Hybrid Gear

That weapon seey, a bundle of state of the art technology

However, Kizuna didn’t understand well just what kind of thing it was

What he understood was that a s like a capsule called core was eh an operation And then, with the power of that core, a cool protector like an armor and a weapon would be equipped on his body

And then when he used that and did the experiments, his mother would be happy, that was all he understood

“You are the only one in the world who are in possession of Heart Hybrid Gear you know? The result of this experiment will become the key to save the world”

He was proud to be relied on by his mother

He felt triumphant that he was the only possessor of Heart Hybrid Gear in the world

He was happy that he was useful to his mother

He felt a little like a hero

――Like that, on a certain day

“Who is that?”

A girl put on a stretcher was carried into the laboratory

“Looks like she is a lost kid She was discovered in Tokyo recently”

“Hmmm”

He wondered as she brought here then? While he was thinking of such thing,

“That’s why, it’s fine for Kizuna to not come here anymore”

“……eh?”

“That girl’s aptitude ability for Heart Hybrid Gear is aless to experiment more than this You are not needed anymore”

Wa,

Wait, a second

“Good bye, Kizuna Sayonara”

Wait!

Okaa-san!

I, ork even harder!

――That’s why!

Part 2

With a gasp, Hida Kizuna’s eyes were awakened

He reflexively looked around him, he was currently inside a train

It was the linear afloats He was nodding off while sitting in it just now

――I was seeing a drea while huh

He felt worried whether he was also talking in his sleep, but there was no one boarding the train other than him

For hi time since he went to the academy float, so he wondered if he was nervous

His ie which was reflected in the as not a kid, but a face of a highschool student The digital synergy which was located near the door was displaying the map of the Pacific Ocean On that

Megafloat(Extra-large Floating Ocean Structure) japan was in thethe Pacific Ocean Inside the train the air conditioning orking, but recently the Megafloat was nearing the equator, so outside was humidly hot

The float was a giant city created above the sea

Tokyo Float, Oosaka Float, etc, each created floats of japan’s adiant structure that was Megafloat japan

That largeness, if it was coeness of district 23 of Tokyo, but such scale was still se countries like Aafloat represented the national power of that country Each country andering the seas of the world with their respective unique afloat

Currently the very afloat itself was exactly the country for the countries all over the world which lost their territory, that afloat was all the territory that they had The crews and residents of the afloat were all the people of the country which could be confirmed as safe in the current condition

For the s like territorial waters held no

World map also didn’t exist

Everything began since the day where the world was overturned

――The First Another Universe Conflict

Fifteen years ago, without any omen at all, without any advance notice, it happened out of nowhere

North America, South America, Russia, China, Australia, South Africa, France, Entrances(Collision Surface) towards the alternate universe were appearing And then, ic and science appeared from those Entrances

Now that it had come to this condition, nobody understood which side was the one that started it But, it was an unmistakable fact that it turned into battle situation And then the fires of war spread in the blink of an eye

The Entrances towards the alternate universe were opened only for teeks, but hundred of cities and fifty million people lost their lives Mankind was coainst the army of the another universe

Like that, the first contact with an alternate universe ended in the worst shape

Moreover, it was a disappoint about the another universe

They only kept getting attacked by the enemy and their side was unable to attack back Mankind was still yet to understand the objective of the people of the another universe or even their appearance

And then, half a year ago

――The Second Another Universe Conflict occurred

It was a conflict on a scale incomparable with the first one

Entrances were appearing on each continent and island country, without exception Fro in with great numbers

Mankind attempted to resist desperately, but mankind’s conventional weapons were powerless in front of the technology of another universe

The army was ruined in a flash and the world was conquered

From the experience with the First Another Universe Conflict, each country was building a ency use and also as the truafloat was the country’s backup plan Not to afloat was equipped with all societal afloats were a miniature version of the countries

Each country that was invaded by another universe abandoned their original territory and becaafloat

However, the people unable to board the afloat were still left behind in the old territory of the country Right now the afloat didn’t have any means to knohat happened to those people

Even if they tried to netic waves were cut off in the land and they couldn’t get any transmission

When they approached their hoic weapons and fleet of another universe appeared froafloat couldn’t carelessly get near even if they wanted to confir

Even while the people living above thea peaceful life above the safe area that was the sea, they ishi+ng to once again take back their country, rescue the left behind people, and return home to their city and house

The linear underground train passed through the Tokyo station

One wouldn’t understand froround there was the station building of Tokyo station that was disinal japan and rebuilt here At the occasion of the construction of each floats, faion of each respective administration divisions were dis the characteristic of the regions, schemes to reproduce the scenery and the likes were performed in the construction

Outside thesuddenly becaht

His eyes were dazzled by that brightness He narrowed his eyes and then looked out the , outside was an endlessly continuing blue sea that glittered froht of the sun White clouds floated in the transparent sky, and then the sun of southern country was shi+ning brilliantly

The linear train ran above the sea crossing over a long bridge

Ahead of this bridge Kizuna could see the destination where he was going

Buildings like a protective wall encircled the surrounding Rapid fire cannons and missiles protruded out toward every direction at 360° The atmosphere was exactly like a fortress

――Tactical Defense Academy Ataraxia

It was a self-supporting float with a diameter of three kilometers, it was also one of the oldest floats

Every region’s floats were also equipped with unmanned city defense functions, but fundaafloat japan was shouldered by this Ataraxia

Right after the Another Universe Conflict, this Ataraxia was the forey, it was a research institution that constantly developed human resources and R&D, other than university, this float was also a joint establishh and middle school

His mother owned a research facility in Ataraxia, so Kizuna was also living in this float when he was small He was chased out froo and was forced to h it was only for a short ti sister there just the two of them

However his big sister too soon enrolled into Ataraxia It made Kizuna live alone by himself

The only ones who could enter Ataraxia were just they who received permission Kizuna was unable to even approach near Ataraxia

Everyheld for several dozen people to go for a field trip there, but he had never got chosen even once

He thought that by any chance he , but every

Although he had sent mail several times to his mother, but he had never received any reply even once

For a while he also had so sister, but it seeradually becaed

And then it was yesterday night that his big sister, Hida Reiri, called hi time

{Kizuna?}

“Nee-chan!? It’s been a long tiht now?”

{I’ed the procedure for your admission into Ataraxia Tomorrow, come until the reception at noon After you take care of the enrollment procedure, report yourself to the coot that?}

“Ha? What are you saying so suddenly Nee-san? My grade is not that excellent you know There is just no way I can go to Ataraxia”

Ataraxia was a place that gathered people in order to turn them into the cornerstone of ht about it, it was not a place he could go to

{I have business with your Heart Hybrid Gear}

Kizuna’s chest felt a sharp pain

“Ahaha, Nee-san said so is not useful you know?”

Frankly, he didn’t want to activate the thing for a second time

He didn’t want to recall hoas being treated like an unneeded child by his mother

Moreover, there was also one other reason

There was a necessity to call out the naear inside oneself in order to activate the Heart Hybrid Gear That was because it was the activation code

He didn’t want to shout out that name

When he was a kid he didn’t ht noas a keyword that he didn’t want to say overtly

{I’ll be the one to decide whether it’s useful or not If you got it, then do as I say If you are late to secrets For exao to toilet――}

“I, I got it! I understand!”

The linear ot down from the train

‘Just what is Nee-chan thinking? No, rather than that, why did Nee-chan ht, I heard that Nee-chan’s work is soh’

By any chance, was she employed in a company related with Ataraxia?

He didn’t knohat his big sister was thinking, but honestly he was reluctant to do this

This place was a place where he had an unpleasant memory as a kid, and it was also the same float where his mother was, those facts made Kizuna’s heart become heavy

He ht encounter his mother He wanted to meet her, but he also didn’t want to meet her

While still harboring such contradictory feelings, he received the entrance inspection

The inspection was to restrict people without permission to enter Ataraxia

The reception was not human, but a three diirl was talking with a synthetic voice that sounded really close to a human voice

“Confired to enroll into Tactical Defense Acadee is 17 years old, is there no h school student?”

‘Uwaa, I’ to be transferred here!’

“Ye, yes There is no mistake”

“Welcome to Ataraxia! May luck be with you”

After he passed the inspection and went through the gate, he was rounds of Ataraxia

“Heee…… I thought it’s going to feel savage because this place is combined with military facility, but the townscape is really beautiful and stylish instead”

Sh the h the road Digital synergies floating in the air were lining up along the sidewalk Advertisements of products and news and the like were projected on theency for urgent information and evacuation instructions

At both sides of the sidewalk, shoppingin a row Ataraxia funda system where all students live in dormitories, houses were also prepared for the personnel and researcher here There was also the inspection that was perforle time someone entered and exited, and so there was a demand for the inside of the float to provide all the necessities for living

In order to answer that demand, all kinds of shop, medical institution, and various recreational facilities were established inside Ataraxia Everything in here was built under the hands of first class architects, so the design here becaarde and futuristic

“Hee, even chain convenient stores have cool appearances here”

When he got attracted by the coolness and tried to enter, inside the store was flourishi+ng with Ataraxia’s students Everyone was talking with their friends while happily choosing lunch or snacks

‘I wonder if right now is lunch break? Or the convenient store also doubles as the school canteen?’

There was also exciting things like cup ramen or snacks limited for Ataraxia, but he would surely have many chances to buy them in the future

He had arrived here afteraround at other stores too? His story

However, whether it was café, fast food, or gyudon shop, everywhere was packed with people Further Ataraxia’s uniform (TN: Gyudon – japanese food that is a rice covered in etable)

‘Hoesome It’s like most of the place is the cafeteria for Ataraxia’

Kizuna thought about the fierce battle for lunch that he would have to go through starting from tomorrow

And then while he alking around like that, he becaly fond of Ataraxia

If the facility was the best, then the shop employees were also polite and kind

The students were also the sa around with casual clothes, they asked hi hi called by many people in concern

Above all, everyone looked happy

At the plaza of the shoppingconcert, at the gaa bento in one hand

In outline, this place should be a military facility, but…… in reality this place was really full of freedom

“Wait, this is bad-! I forgot to go to the command headquarters!”

Well, if he just walked through the appropriate streets, he would surely find a building that fits the bill, there uide board around Even if not, everyone here was kind, so it would be fine if he just asked someone for directions

Having an idea like that, he began to walk

――But,

“I’m lost……”

Ataraxia ider than he thought, he couldn’t find the high school or the co with the end of the lunch break, there was noaround outside

“Or rather, where is this place?”

For so inside a forest

“Why is there a forest and river inside an academy float……”

Even if he tried to go back, he already didn’t understand which direction he should go to go back

“A to school and die? It’s already past the level of being idiotic like that”

Right when he was thinking that, he walked into an open space further inside the forest

“I did it! I finally returned to the city!”

Happiness welled up inside him and he rushed ahead

“……-!?”

When he got out of the forest, he found a sea there

Kizuna stopped his run so suddenly that his body pitched forward

The spot where he was at was the brink of the float It was like a precipice cliff, the wall of the float’s hull was continuing until far below

The hull of the ht could even reach several dozen meters

“I…… I almost died”

But, there was so that attracted his attention even more than that

A large type rapid fire cannon was set at the outer edge

A girl was standing at the tip of that cannon

Her back was facing hi from the sea wind

He was going to call out to her, but he hesitated

If he called out carelessly, she ht fall

Cold sweat flowed down Kizuna’s forehead

‘This place looked deserted shi+t, what kind of scene I’ here’

Should he call for help?

Kizuna was going to step back, but he stepped on a branch lying under his feet

The sound of the branch snapping irl turn to him

“Ah……”

Kizuna’s eyes were stolen by her appearance

‘Aah, she is not a human, she must be a CG character like the receptionist If that’s so, then it erous place like that’……hat he thought

He was thinking like that because he couldn’t think that so human

Long silver hair and red eyes

Delicateness and beauty that was like precisely crafted porcelain, it was a girl that gave the impression of hardness and yet also brittleness There was no way that this much conveniently beautiful human could exist

Her height was normal, but her head was a little small compared to her body’s tallness She had slender proportions to the degree that it made him worry that she would break, but her breasts were so big in imbalance with her body

Her skin hite and s at her face from the side, he couldn’t think of any other word to describe it other than a perfect beauty Her red eyes that looked as if they were eht the eyelashes were hiding that sadness That sorrowful gaze was directed at Kizuna

Those red eyes were reflecting light in a sparkle

Was she…… crying?

But rather than that, a girl with a beauty this transcendent was looking at hiaze Just that factin the sky

Even the idols that irl in front of his eyes, they were just like normal people

This girl was like a different living being from somewhere, he could feel that difference in dimension from her

That girl, alking to his direction

‘Eh? Eehh-? A, a real thing?’

She lightly ju over the bumps, and moved back from the rapid fire cannon to Ataraxia

Her glossy pink lips were

“Who are you?”

‘She talked!’

‘Err, how should I reply? My, my name? Is it fine for me to introduce my name?’

The girl knitted her eyebrows and showed a face that was seriously glaring at him

“I wonder if you don’t have the intelligence to understand words? This is the first time I saw an animal like this……”

Just now she said so really mean to him!?

“No, I understand your words but…… I’h school here You are, a student here right?”

“That’s obvious isn’t it? If I’m not a student then just what do you think I am, I wonder Someone who purposefully ordered this uniform, slipped into this place of heavy security, and stared at the scenery in this kind of place?”

“No, you don’t need to find fault infault here in the raritten with the kanji of ‘raising foot’ Solish itfault)

“Finding fault? Just why in the world this me has to take the foot of someone like you? Rather it’s a different story if you are the one that cries and begs to , ‘please let me kiss your beautiful foot’”

“I’ like that at all!”

“What a dishonest man”

What ith this girl? Even though her appearance was the most beautiful and cute he had ever seen, but he couldn’t understand her strange thought process at all Whether she had a bad mouth or a bad personality he didn’t know

“I aafuchi Aine, a second year It’s fine if you want to worshi+p me”

“What I’h to you at all! Just how does it take this much just to hear your name”

“Rather, you should express your joy that you can hear the name of this me this easily Now, dance the dance of joy, make this me enjoy the attraction”

This was hopeless Her visual appearance was the greatest, but it seeirl was for the best He was thinking of asking her for directions, but like this his mind would be destroyed in return for the directions he asked for

“Ah, well, I’ll be going――”

At that ti

“Wh, what!?”

What kind of alarm was this? At the very least, it was certain that it was not the signal for the class starting

Or else, was this a disaster drill?

“Evacuate to the shelter immediately”

Aine spoke to him with a serious expression

“This is the air raid alarm”

Ai…… air raid, alarm?

“Tha, that’s iht noe are in the safe area of the Pacific Ocean you know? Those another universe bunch should not have cruising range this far……”

The army of another universe for soe froafloat was created

“But, this should not be a false alarm The enemy has appeared, that’s a fact”

After saying that, Aine began to strip off her clothes

“Wha, oi! What the hell are you doing!?”

After taking off her upper wear and hung it at the nearby tree, this time she unfastened the hook of her skirt Like that she took off her skirt and hung it at the tree like her upper wear Wearing a panty with a cut, when she turned her back to him, he could see almost half her butt bared naked to hi into the crevice, so itanything

“……You are still in a place like this?”

Her movements stopped from a little shock

When he saw that her cheeks were a little red, it seemed that it was not like she was not embarrassed

“I’ve told you already to go evacuate haven’t I? You dullard”

“You yourself, just why did you suddenly begin to strip! What are you going to do if somebody sees you!?”

“The one looking here is only you This molester”

While saying that, she unfastened the buttons of her white shi+rt

“Turn away your eyes If you do that then there will be no probleot peeped at one-sidedly, while you are the pervert who is one-sidedly peeping at me”

“You are the pervert who is showing all this to me one-sidedly!”

But certainly if he averted his eyes right now then all this would be settled Though he couldn’t comprehend this at all!

“If we are going by your reasoning here, then thatobscene you know…… hey, oi!!”

Aine unhesitatingly took off her white shi+rt

Kizuna tried to avert her eyes in panic, but his movements stopped in the middle

“……?”

What could be seen under the white shi+rt was not brassiere

What she earing under her uniform was a leotard with surface area that was extremely small

The center of the leotard was opened, it was as if the clothes were flaunting the valley of the breasts and the navel, exposing thele while her sides were virtually uncovered

It looked really erotic

Aine’s body line becae breasts were shaking in jiggles following heroff her clothes

However, this leotard with high exposure rate was not soymnastics

“That’s…… a pilot suit?”

“Even though you are ignorant, but you are widely knowledgeable only in fe your head is really troubling”

“That’s not underwear in the first place! No wait, it lookx like underwear though!”

He was staring fixedly at Aine once again

There was no mistake, this was a pilot suit

This girl, could she be――

“Zeros!”

When Aine shouted that, glittering blue lights surged out from her

“You-, you have done Core’s Install(Internal Operation)!?”

The blue light was turning into the shape of Heart Hybrid Gear

The created shape of the gear was equipped onto Aine as if digging into her soft body

Armor modeled after vertebral column ran on her back as if in protection of her spine And then, the largest thruster appeared on her bottom This part was responsible for the majority of her propulsion force

On the other side, the front part of the body had surprisingly few areas which were protected There was no conspicuous arh However attack fro was easy Moreover, there was the basic function of Heart Hybrid Gear, the Life Saver(Absolute Territory) systeave protection to the wearer

This was a sudden talk, but Life Saver was a powerful barrier equipped on Heart Hybrid Gear

When the blue light enveloping her four liirl equipped with a gear that combined protector and thruster There were a lot of thrusters on her whole body, so he could guess that it was a gear with fairly high mobility

When her silver hair was brushed off smoothly, blue particles danced in the air

“This is…… Zeros”

Its brilliance was beautiful, blue light was running through the sleek white armor

It was a simple but really sharp Heart Hybrid Gear

He thought that this beautiful gear didn’t lose to that stunningly beautiful girl possessing silver hair and red eyes

Heart Hybrid Gear was hiding a power that greatly eclipsed mankind’s conventional weapons It was the ultiy that displayed an unrealistic perfory of another universe from the enemy

But, there was one point that bothered him from the Heart Hybrid Gear in front of his eyes

――There was no weapon

“Can I ask you a little? Is there no weapon in that Heart Hybrid Gear?”

Her red eyes glared at him

“Please don’t say is Of course it has proper weapons”

What? No wait, perhaps it was an internal type weapon So even a gear this small had the parts fitted really well

“It’s a weapon invisible for an idiot So you cannot see it How pitiful”

“Rather than callingthat kind of story is the one that sounded like an idiot!”

“This gear is paying serious attention to its stealth”

“A technology thatcoless!”

Aine was crouching down on the ground and then she grasped so like a handle

What was that? He didn’t realize so like that was there at all

When the handle isted, the ground opened quickly, then a metal box appeared from inside it

“Eh-?”

Inside the box was firear up in a row

Aine took one firear them It was a 89-style pistol

There was nothing unusual about the gun, it was just the official firearm that the Ground Self-Defense Forces utilized once

“Yo, you…… you are, using that?”

“What is it, you have complaints?”

No, he was not coh

Heart Hybrid Gear was so that had arear was furnished with a beah its offensive poas low

But, Aine’s gear was not furnished eapons fro

“You are going to fight with that kind of weapon!? Conventional weapons are ineffective against ht?”

A ring of blue light was floating around Aine’s waist

The Heart Hybrid Gear was raising its output That was the sign of co

“It’s fine already, just escape, you are going to die if you stay here”

Leaving those words behind, Aine faced to the sea and ran, then she fleay froht stretched out fro up Aine to the sky

“shi+t-!”

Kizuna started running

‘Her afuchi told me is correct

My aptitude with Heart Hybrid Gear is low, and to begin with I haven’t trained for battle with it since I was a child So that I won’t drag her down, I should evacuate to the shelter

――But,

I just can’t forget Chidorigafuchi as standing still alone with tears shi+ning in her red eyes’

Kizuna alking towards the direction where Aine was heading

His speed was gradually turning faster, before long he had started to run

Froo to a more open place!

When he ran along the outer edge of Ataraxia, before long he exited the forest and came out into a wide park

“Wha――”

A gigantic object was flying above his head where it alale attacked Kizuna

Giant!? No, that was a ic weapon!?

By crouching on the ground, he so bloay

That was the ic weapon of another universe! He had seen it before from a photo

It was a ht that surpassed ten ned with ars that possessed flying ability, an [Albatross]

No matter how he saw it, it shouldn’t be able to fly in the sky based on aviationin the sky with her than an airplane He didn’t understand at all hat kind of technology it was flying in the sky

The technology of the another universe far surpassed the common sense of mankind

And then, after that a sh him in an instant

‘Chidorigafuchi!?’

He chased the back of the figure flying past hione already When he looked up, he could see a white Heart Hybrid Gear ascending high to the sky chasing after Albatross

Aine pulled the trigger of the type-89 gun in her hand and scattered sparks on Albatross’ back

That was a good skill

If this was a dogfight, then this would be Aine’s victory

However, the armor of Albatross repelled those bullets really easily
