A/N: Hi KuroKapibara here!

Welcome to my first new story. Thanks to a friend who recommended me this anime/manga, I came into the world of World Trigger and immediately became obsessed with the story. I wanted more, sadly World Trigger is not popular as it should be. There is not enough material to satisfy me (except for great few fics). So my mind started to create stories and I wanted to contribute to the World Trigger community and grew courage to write this fic. I hope you guys like it.

English is not my native language and it's not beta-ed, but I wanted to practice. So please bear with me and feel free to correct me wherever I made a mistake. Also if any kind soul liked the story and want to help me by beta reading it, I would be ecstatic and really grateful.

Disclaimer: KuroKapibara does not own World Trigger, the credit goes to its creator ASHIHARA Daisuke.

Enjoy!

Chapter 1: Calm before the storm

Neighbors are those who inhabit adjacent worlds called Neighborhood. Four and a half years ago, a gate to another world was opened in Mikado City, by those who sought Trion and a large scale invasion took place. The battle was known as the First Large-Scale Invasion, people tremble with fear and thought their city would be destroyed. That's when a mysterious group showed up and got rid of the Neighbors.

The invasion was brought down by the action of Border Defense Agency, namely Border. Since then Border has pressed forward with studying 'Trigger' along with Neighbor technology and has been battling them. And so, Mikado City has been kept in peace through their actions.

Now again, four and a half years later. Mikado city was exposed to the Neighbor's large-scale attack by the military nation, Aftokrator. The Trion Solders and the Humanoid Neighbors who manipulated the powerful black triggers came to invade. Standing up undaunted and bravely against the surge of unbeatable enemies were the border agents. Finally, the helm was steered towards their victory at the crossroads of fate at the cost of a great sacrifice.

With the threat no longer present and their determination reaffirmed, our heroes Yuuma, Osamu and Chika, sought to move forward to achieve their goals, aiming to get selected for the away squads to the neighborhood. Therefore they engaged in the B-Rank wars in which they claimed victory in every tussle, thereby making them an official squad known as Takoma-2 of the branch division.

As official agents they were now part of Border and so our heroes took the oath for which the Agency was created: Guarantying the security and protection to all the citizens of Mikado City from the threat of the invading beings, the Neighbors. And sooner than they expected, Border was putting that motto to use since they were now facing another invasion, culminating the brief time of peace in which all the agents had fought for. All agents, from A-rank, B-rank, C-rank, S-class and elite, were fighting hard throughout the city, repressing the incoming waves of enemies of all kinds.

Will border be able to, once again, triumph in the presence of the Neighbor's menace? Even now when they were taken by surprised, even more when they were just recovering from the preview invasion? And what would be the prize to pay for this victory?

- Calm Before the Storm -

"Asteroid!"

Complying the voice's command, a luminescent bluish cube manifested itself spinning slowly right above from a gloved hand, as in making them known it was ready to fire. The trigger didn't waste any more time before the cube divided itself in smaller bullets and honoring the name it was given, all the Trion Bullets left the housing palm in a quick motion like deadly accurate asteroids, heading towards their enemy. Who happened to be a rare cross between a rabbit and a Saltasaurus.

The type of Neighbor specialized in capture of civilian and extraction of Trion called "Bamster"; not the toughest of the bunch, nevertheless for those who had encountered this Trion Solder before would agree that penetrating the harden carcass was a pain to deal with. However, this Neighbor was its counterpart, a mid-size Trion Solder the "Bander"

The Trion Bullets impacted and perforated right on the weak spot of the giant, something not difficult to find since said weak spot resulted to be an eyeball in the middle of its toothy mouth. A trademark between Neighbors and forever engraved in the minds of all citizens. Hitting the weak point of the Trion Solder was the basic strategy to neutralize the enemy, especially to those who weren't strong enough to penetrate the thick armor or didn't want to waste any more time and keep it simple.

With the eyeball shattered and the prime source of Trion no longer functioning, the Bander was reduce to a large carcass crashing down on the buildings and houses that were slowly but surely being evacuated from its residents.

"Kya! Osamu-kun you did it!"

"Osamu-kun defeated the Neighbor!"

"Way to go, Osamu!"

"Give your best, Mikumo-kun!"

"As expected from a Border agent!"

"Mikumo, don't let us down!"

More and more cheers and acclamations filled the combat zone, all coming from the fellow classmates and students of the school that had been transformed into a battle ground. The preview atmosphere of fear and despair had dissipated, being replaced by the hopeful mood within every person at the promising scene taking place thanks to the act of the agents before them. The sight brought them hope and tranquility that was what Border signified to all of the citizens of Mikado City. Forget all the stuck-up press who always blamed the Agency after all its agents had risked their lives for their safety and protection.

The people of Mikado City were with Border until the end.

'It was nothing really. The other squads would have done it faster and struggle less than me.' The acclaimed boy responded awkwardly in his mind.

The boy's name (if someone hadn't caught it after being acclaimed by the multitude) was Osamu Mikumo, a 15 year old teen who possessed black hair and green eyes, he wore his trademark glasses, something almost all his acquaintances from Border have come to acknowledge him for. His bright blue uniform announced proudly of his status in the organization, a B-rank agent and the leader of the three-man squad, Tamakoma-2. Osamu carried on one hand his Trion weapon 'The Raygust' excellent for defense more than offense. On the other one, projected floating above his palm was the responsible for the downfall of the large Neighbor, the Asteroid Bullets which showed his position as a Shooter.

A first glance Osamu was your typical nerdy boy, weak, scrawny, goody-two shoes, not ideal for prolonged physical activities much less for combat, and never forget his small Trion level. However behind those geeky glasses, an incredible mind was hidden, the mastermind behind the victory of his team in the rank wars. What Osamu lacked of physical condition and combat ability, he compensated it with creativity and wisdom, both attributes showing through his insane and successful strategies with also the capability of reading his opponents and learning from them.

'They should be evacuating the school, not watching the fight' Osamu sweet dropped. His mind wandered to the time not long after he had met the feisty humanoid neighbor. The invaders had appeared in the school putting at risk the lives of the student body. He had tried to confront the intruders, only to end up being saved by Yuuma and giving Intel to the Aftokrator Nation about the C-rank agents. But that was before all the events had taken place, Osamu was positive that in the lapse of time between that encounter and now, he had been able to grow and improve.

Distracted by the scandal caused by the students and immerse in the depths of his mind, our hero failed to notice a Bamster making its way silently toward him. The preview cheers of enthusiasm had turned into distress shouts of warning at the direction of one of their saviors. Osamu snapped out of his line of thoughts when he picked up the change of mood from the bystanders who were desperately signaling directly behind him.

Osamu with fear in his body, rotated to face the source of warnings and immediately curse himself. How could he have been so stupid to get himself distracted in the middle of the fight, after all the times he was reminded by al his senpais to keep the head in the battle.

There was no way Osamu could avoid the incoming attack, not when he was face to face with a charging Bamster. The only way to survive was to change his Raygust into shield-mode and pray it would endure the attack, which he knew it would since the Raygust had withstand the impact of a Rabbit. But how many times could it last before it breaks? He didn´t know.

However the Bamster didn't have the opportunity to strike when a powerful ray shattered the eye of the Trion Solder, defeating him and making it scrap in the process. The leader dared to take a peak after waiting for the impact that never came and, once again, the shouts returned to those of joy and excitement at the potent counterattack that had neutralized the enemy.

Osamu couldn't help but to heave a sigh of relief; he had forgotten the most important part of this operation: he wasn't alone. 'Thanks, Chika' Four eyes silently thanked the angel hiding in the in the tallest part of the building, for watching upon him and coming to his aid. He guessed after all the time he looked over her, it was now her time to return the favor and good thing too because Osamu hadn't seen a good outcome.

Chika was other member of the Squad, a 13 year old girl with black hair and expressive violet eyes. Chika was shy, polite, well behaved and kind-hearted. All this was ignored, being recognized for only on thing. The small girl had gain fame at Border and sometimes agents would only assist the matches to witness the devastating cannon being fired. The well-earned nickname was "Trion Monster" also known by his enemy as "The Golden Chick" because contained in that small package was the biggest Trion capability someone could own.

Other people would think of this gift as a blessing, but not Chika, for her it was a curse. A curse her best friend and brother had to pay the price instead of her, when the only thing the two kind souls wanted was to protect her. Chika never forgave herself, however thanks to her friends, Osamu and Yuuma, she had found hope yet again and a possibility to avenge them to show them their sacrifices hadn't been in vain. She was a fighter now and she would save them no matter how long it would take her… that was, if they were still alive in the neighbor worlds.

The Tamakoma-2 leader visualized the Neighbors specialized for combat, The Marmod. Three of them were heading directly towards the school buildings where all the students and teachers were still residing. 'How long it would take to evacuate the building?!' It would make things easier if they didn´t have to worry for the student body.

Osamu wasn't confident if he could defeat the three Trion Solders, sure he had won against a Marmod before in the preview invasion but that was after hours and hours of constant practice in the Tamakoma training room to finally be able to beat just one Marmod. He doubted he could fight two at the same time, let alone three. And again, before Osamu took a step forward, a white and blueish blur passed over the three Trion Solders. For the first seconds nothing seemed to happen, the Marmods kept their trajectory heading straight to the group of defenseless civilians who shouted in terror at the incoming doom.

'What?! There was no way Kuga had missed! Now I won't make it in time-' as a way of shoving his insecurities about his friend away, the three Marmods simultaneously burst into green particles of Trion just barely centimeters near their destination. It had occurred so fast that the aftershock left everyone blinking in confusion as they slowly came to the conclusion they had been saved and were no longer in danger. Once the scene had been assimilated the renewed cheers drowned every single structure in the institute.

"Hmm. They can be loud when the want" Informed a smug voice.

Osamu visibly jumped in his spot with the sudden voice coming from behind him, not because he didn't know the voice's owner. No, in fact, he had come to familiarized himself with the owner since he had been thrown into the world of humanoid Neighbors and other worlds thanks to the mysterious albino. No, it was because all the occurrences were starting to get the best of him.

Osamu knew he would have snapped long time ago if it hadn't been because his squad were counting on him, they had been the ones who had trusted him, believed in him enough to make him their leader. Osamu would make sure not to disappoint them.

"They don't seem to worry with the incoming Neighbors, not even when they know their lives are in danger and they could die" The white haired teen wondered out loud, dismissing the Trion-made weapon, 'The Scorpion'. Usually the person's instincts would have made them run in the opposite direction of danger, instead this odd ones were cheering quite loudly while being surrounded by deadly machines not caring in the lightless if they could be hurt by the crossfire. He would never understand the native people of Midden.

The Black haired teen tried not to visibly flinch at how easily his friend talked about the possibility of someone losing his life. He cleared his throat and adjusted his glasses, trying to compose himself. "It's because we are here, the agents of Border, fighting to protect them." Osamu responded at his companion's statement.

"Hmm. They have a lot of faith in the Organization" Said his friend while his penetrating red-eyes inspected his surroundings.

"Well, Border has never done anything to prove them wrong. Especially when they have agents like Jin-san, Tachikawa-san or Kazama-san. There is also Shinoda-san too." 'And don't forget about you, Yuuma' Osamu complemented in his mind. It was incredible how strong agents like them existed, and relatively young at that. "I don't see them being defeated so easily."

"True, true" The boy recognized as Yuuma agreed comically with a nod of his head and a hand under his chin.

Last but definitely not least was the boy who was more than met the eye, Yuuma Kuga. White hair, unusual red eyes, and short stature for a 15 year old; along with a goofy, childish and clueless attitude without concern in the world, were the things people tended to notice at simple sight of the boy. However the teenager was a box hiding tons of mysteries inside, one of the first enigmas to unravel was Yuuma not coming from this world, actually the albino was from the other side, the world feared and hated by the people of Mikado City, the Neighborhood.

Contrary of the citizens beliefs, the Neighborhood wasn't just one world but a compose set of various stars or worlds floating within the endless darkness of space, named "planet-nations" by Yugo Kuga, the late father of Yuuma. Yet those countries weren't just invading the bigger planets happily together, taking turns on who would trespass the barriers of earth just for fun. All the Neighbor nations were all tangled in a big Trion War with each other, and Midden (Earth) was the unlimited source of Trion.

With the war going on, pain, despair, hurt, hate and dead were common among the habitants of the floating nations. Their children were force to grow faster without a good childhood, some of them without the support of their parents and if the kids resulted to be Trigger users, they were enlisted and trained to assist the forces in the war.

Unfortunately Yuuma fitted perfectly inside the category.

Yuuma started to be trained at a young age under the tutelage of his father as both of them were Trion Users, both of them aided in the fights. Even so, father and son fought for a different cause than the military from the other nations, they fought for the protection of those who couldn't defend themselves, who were at the mercy of countries more powerful than them, only waiting to be slaughter. Despite participating in the war, both of them enjoyed their everyday life.

That was until Yuuma died

…or at least, was supposed to.

A mistake, a single mistake took for everything to go downhill. When they were assisting the country of his dad's friend, the fight wasn´t looking good and troopers were needed thanks to a mercenary killing the few Trion Users they had. Fearing for the safety of his only child, Yugo had order Yuuma to stay behind but it was like ordering a child to not eat the pastry in front of him, there was no need to say the kid had disobey the orders without thinking it twice. That had been the mistake that had cost his life, the mercenary had found him, wounded him and left him to die. As last resort Yugo had sacrificed himself to save his beloved son, restoring his body with the creation of a fake Trion body while creating a Black Trigger and sealing Yuuma's real body inside it.

It had saved his life, however it had turned Yuuma in a ticking time bomb. Living on borrowed time, waiting patiently for his real body to die along with his fake one.

Since then Yuuma had fought the pending war on his own for the past four years, until the attacked nation finally claimed victory. With the war won, the albino was left with no purpose in life, but thanks to Replica, Yuuma's chaperone, who suggested to accept his creator's proposal to go to Japan; the duo embarked on a journey to discover the planet Yugo talked so much about, the place where they would meet Osamu, Chika, Jin and the others.

Behind the goofy mask Yuuma carried around was the molded veteran he really was, a prodigy in combat. When it came to fighting, the human neighbor threw away his façade and the cold calculated fighter surfaced. Because Yuuma knew how harsh life could be, he lived every second of his limited time at his fullest and treasured every person close to his heart, meaning he would do everything in his power to guaranty their well-being.

"However, Osamu. No one is invincible and everyone can die no matter how strong they are, never forget it" The previous childish mood Yuuma showed was replaced by a serious gaze that could freeze anyone under the stare and Osamu was no exception. However, Yuuma held a soft spot for his friends and couldn´t be mad at them for so long, not that they had ever have a fight before; so when his carmesi eyes landed on his leader they softened a little but not enough to stop the effect of his scolding. "A simple mistake can decide your fate, therefore always keep your head in the battle and don't get distracted."

"…" Osamu didn't know how to respond at that, Yuuma had never been like that with him before but he guessed he deserved it. So the black haired boy would take those words as an advice, knowing very well they were the result of many years of experience. It still made Osamu sweat a bit "H-Hai! … I'm s-sorry"

"Mmm, just be careful next time, okay? Good thing we have Chika covering our backs… I told you she would be a good combatant" And again the preview mood of Yuuma gave a 180° turn, it made Osamu wonder if his teammate was bipolar with his constant change of moods.

"Yes, yes you did" The young strategist sweet dropped even more.

"Well, I guess that was the last of them, it seems we ended all the Trion Solders in the school." Declared Yuuma changing the topic right after a quick inspection to the institution.

"Hmm, it seems that way. I still can't believe just the three of us manage to stop an entire wave of Neighbors." Osamu stated with a mix of disbelieve and relieve. He let himself a moment of peace to relax his muscles and his whole aching body after the exhausting fight.

"Why not? Other squads have no problems exterminating hordes of enemies. So why are we different?" Asked Yuuma lightly insulted by his leader's words, even though he didn't showed it.

Oh, Osamu had said something wrong to cause a small reaction on his feisty friend, it wasn't noticeable but the hint was there. He shook his hands furiously as he tried to amend his preview statement. "Wha… No! ... I mean… I wasn't…" His mind was a tangled mess not letting him make a coherent word. Osamu had to stop right now if he didn't want make it worse while being in this mix-up state. He had to stop, rewind, clear his mind and start all over again. "It's not that I don't believe in you. Well, you can hold them off, that is obviously clear."

"Osamu-" Yuuma tried to intervene partly because he felt a little guilt for being the factor Osamu needed to break down. He had seen this situations many times before with solders from the other side, the short boy was sure he didn't want his friend going through that. However the intent was futile with his leader engrossed in his monologue.

"Chika too, can defend herself… But me? I'm in the border line of acceptable in Trion and physical ability, I can barely fight and stand to others. What good is that? You guys are the ones who always do all the fighting while I'm a hindrance to the squad…" Osamu continued to pour his mind to the outer world.

"Osamu-" Yuuma tried again a little stern this time and like the preview try, it didn't have any effect.

"… Always having to protect me. When we first met with the Bamster, when the 2 Marmods attacked the school, in the invasion with the Rabbit and the Aftokrator's Humanoid Neighbor. It was my fault Chika was turned into a Trion Cube and…and…a-and…" Osamu was a cascade of sweat by now, remembering all his mistakes made him feel useless and weak, it turned his throat dry especially every time he thought because of him Yuuma was alone. The black haired screwed his eyes shut while gritting his teeth and tightened his knuckles until they turned white under the glove at the scene reliving in his mind, one after another. "and..It…I-It…It was my fault Replica is gone!"

"Enough, Osamu!" The ace of Tamakoma-2 cut sharply at the rambling of his teammate. Yuuma hadn't intended to sound mad but he really didn't want to enter that point.

Luckily, this time it had the desired effect. Osamu snapped out the limbo of his head with loud gasp and he instantly opened his eyes, resembling a deer caught by headlights. All his body trembled at the exertion it took from his panic attack. He gave quickly small breaths so he could calm himself "I-I'm *gasp* s-sorry"

"It wasn't you talking." Said Yuuma, trying to appease his shivering friend. "Well, it looks like all the stress finally got you."

"A-Again, *pant* So-sorry … I got *pant* l-like tha-" But his constant apologize weren't necessary for his teammates.

"Stop. It happens to everyone sooner or later, even to the strongest solder" The albino tried to console his friend.

Yuuma had to admit comforting wasn't his forte, so he usually left his comical self to do the talking for him, it seemed to always work but he wasn't sure if it was the best thing right now. Personally it had never happened to him, not even after the passing of his father. The war was to blame, it had consumed all his time that it didn't let him mourn properly. Because of it, it had giving him false hope. A part of him still hoped for his father to return, that was why the human neighbor had come to Japan, aside of what Yugo had said.

"Right. I guess, I wasn't really recovered from the preview invasion. And now with this one, it only added more weight to the stress" Explained Osamu.

"That's all right, Osamu-kun. Everyone has their limits." Reassured a girl's voice coming from the auricular of his ear, and joining the conversation as if she was right next to each other. Which in reality, the owner's voice was but a few meters away watching patiently over them. "But Osamu-kun. You did protect me, if it hadn't been for you I would have been capture. So please don't think of yourself like that."

Yuuma agreed nodding comically and enthusiastically to support the girl's statement and giving it more weight and truth, since the voice could only do much in lifting his teammates confidence.

"Oh, Chika!" The strategist was startled by the intrusion of the sweet and tranquil voice. He wasn't going to lie, he had forgotten about their female teammate was present too, even if he had previously talked about her.

"You should believe more in your squad, believe more in you. We hadn't made you our leader in the first place if we hadn't trusted you." Declared the humanoid neighbor as he put an encouraging hand on his leader's shoulder.

"I agree with Yuuma-kun. We are a team and we support each other" Affirmed the youngest integrant of their team.

"Guys…" It moved him how his two best friends put such faith into him and not just them, faces of different individuals came pouring into his head and soon enough, he started to put names to the matching faces. Jin, Kyosuke, Shiori, Konami, Reiji, Jun, Tokeida, Kitora (in her strange uncaring way), director Shindo, director Shinoda, Yotaro and even Reijinmaru; all who had entrusted him their confidence and had made their best to change the terrible fate he was destined to have.

Slowly his visibility started to turn blurry with happy tears waiting anxiously to be left out. Osamu wished for everything to be always like this, to always feel this joy and happiness with the ones close to his heart.

Alright, now he was being stupid for becoming this cheesy in a time like this. Just look at him, wanting to cry in the middle of the fight, of all the times it had to be in the possible worst one. Osamu shook his head, dissipating the lingering feelings responsible for his mushy condition. The occasion for crying at the heart's content would eventually come, but right now the situation called for a determined leader who his squad could rely on and he definitely would be that leader. "Yes, you are right. We will give our all and do our best!" Their leader declared proudly.

"Hai!" "Alright!" agreed the squad without complain, happy to see their leader back to his former self.

Osamu once again took the role of the leader his squad members had conferred him with. It was time to turn serious again and so, he adjusted his glasses and as respected leader, started to give orders. "First thing first, we have to regroup before we head to the other parts of the city. Chika come back and met us down here."

"Hmm!" It was the las thing the violet eyed girl said before ending the communication.

"The sacrifice of Replica wasn't your fault" The voice had been not louder than a whisper however it was enough for Osamu to hear the words loud and clear "I ordered him to protect Chika and you and he carried with the command until the end. You shouldn't be feeling bad, instead honor him by respecting his wishes… That is what I do." Yuuma hadn't been facing his way so he didn't know the feelings his friend had but the boy with glasses was positive the face was stone cold as always when moments like this happened. Even the voice had been devoid of emotion but a subtle crack in the declaration had made Osamu reflect upon the truth about his friend.

The last statement was said as an afterthought, quiet enough not to be hear by anyone but the speaker. However with the short distance between squad members and the acute hearing Osamu possessed, he managed to overhear the personal confession without any problem. Those words despite being quite as a murmur, they had struck hard and deep into the older boy's heart.

'Osamu, this is goodbye. Take care of Yuuma' Replica's farewell didn't ask for permission to invade Osamu's mind, the flashback came barging in after being confined in the farthest corner of the brain. The words of Yuuma and Replica ringed together intertwining themselves as he watched again and again the unwanted memory. The testament of the friendly Trion Solder, his dying wish, his last wish… wish! Of course! Since they met, Replica had conferred him with the only important thing for the friendly Trion Solder: Yuuma. The chaperon had even asked him to give a new purpose in life to his charge, when said boy had been left without any motivation to keep living.

Osamu owed it to Replica at least that much, so he decided to heed Yuuma's statement and make a promise to keep the impulsive humanoid neighbor out of trouble. Oh… in what mess has he gotten into now, controlling Yuuma is like trying to contain a child who has eaten all the candies from his Halloween bag, definitely not an easy job, not at all. But he had taken the vow, he wasn't a person to back down on his word, not now not ever.

For Osamu, his little episode had apparently lasted long endless minutes in his space of thoughts and yet, not even one had passed in real life. Even so, that minute had been enough for him to make up his mind, it had filled him with renew encouragement, one who he intended to transmit his (newly acquired) charge. Before Osamu could express the inspirational speech his brain had come up within the short time to animate the feisty boy, said boy decided to speak first.

"Yosh! Let's head to the next wave" This time Yuuma had turn to meet with his leader, showing his childish self once again. 'Well, there goes my motivational discourse' By now Osamu was getting used to the rapid change moods his friends went through, so it wasn't too surprising when the albino had acted as if what just transpired hadn't happened at all. Well, the boy with glasses was okay with that.

"Let's not rush it, Kuga." Osamu tried to appease his hyperactive friend. Still, there was something in his mind, twitching, nagging at him to be listened. He shifted his focus to his neighbor friend, wondering if he too thought the same. "Still, I wonder, who the one behind this sudden invasion is. You have more knowledge in this topic, Kuga. Do you have any idea?"

"Umm" The ace of the squad stroke his invisible beard in an effort of decipher the culprit, unfortunately there wasn't enough evidence to pinpoint who the perpetrator nation could be. He turned to his black-haired friend who was waiting patiently for an answer and just shook his head not able to give any real answer. "No, Sorry. The Trion Solders are the common type so, there is no way of specify the country and we didn't check the hologram of the Planet-nations to know who was near so it could attack."

Osamu deflated at the negative response he got. "I was afraid you were going to said that"

But another thing came to Yuuma's mind, the face of a certain elite agent who loved to act behind stage and the one to blame for his involvement with border. The short boy put his arm behind his head in a careless manner as he said. "Maybe Jin-san knows, you know with his Side Effect to look at the future"

"Probably" Osamu agreed with a quick nod, nevertheless they would only continue in the dark until, by a miracle (because an elite agent must be pretty busy in a conflict like this), they find Jin and confront him. "However this attack took us all by surprise. I'm not sure if even Border was prepare, after almost all the agents were at school."

Indeed, all had happened when agents had been attending their respective classes. The day had been a normal one, Osamu and Yuuma along with his classmates were in their classroom (probably not by their choice, some of them would rather be enjoying the perfect sunny day the world had to offer), being lecture by their teacher. Everything had transpire normally and boringly, complying with the monotonous itinerary of everyday. No one would have imagined that minutes later the institute would have transformed into a war zone surrounded by Trion Solders.

Suddenly the radiant sun had been swallowed by a sea of threatening dark clouds, making everybody wonder if it was an incoming storm but to everyone dismay it had been far worse. A deafening alarm had went off, the alarm that had alerted the brave young warriors it was show-time not too long ago, yet what made it different this time was that it hadn't been foreseen making them unable to plan ahead for a better ending.

At first no one moved, not even the Tamakoma agents, waiting hopefully for someone to come and said it was a prank. Unfortunately that hadn't been the case, when the deep-black portals like worm holes started to appear that's when everyone realized the shocking reality and so, chaos ensued. It took several minutes for our heroes to calm the stampede of frenetic students, but soon enough the student body were being evacuated under the supervision of the C-rank agents which consisted only in Chika's friend, Izuho Natsume an… interesting girl.

Of course the safety of the citizens was priority but some agents, merely Yuuma, was growing restless, craving for an energetic fight. When finally his desire was granted, Osamu, Yuuma and Chika suited up (which made the bystanders suspend the evacuation to cheer in excitement) and made their way to the battle field where a horde of Neighbors where waiting.

And so we arrived at the begging of this story, where our heroes were valiantly fighting for the protection of the student body from the waves of Trion Solders.

"Oi! Four eyes, Yuuma!" Shouted a voice from behind.

Both Borders agents turned at the source of the voice who turned out to be a young man, they would guess with 19 years old. The intruder wore baggy pants, combat boots, a plain white t-shirt covered by a blue border agent jacket that stated he was part of Tamakoma branch, same sector our young heroes were. He also possessed brown hair and piercing blue eyes, unmistakable characteristics for those who knew whom could only belonged to.

"Jin-san!" Exclaimed the one referred as 'four eyes'.

"Yo! We were just talking about you, Jin-san" Greeted the shorter of the two with a goofy smile.

"Ho… is that so?" Said the newly arrival as he made his way toward his two kouhais from the rooftops. Just like any border agent who appeared not to know there was a space on the ground called sidewalks that allow pedestrian to roam without trouble. "Worry not, the elite agent Jin Yuichi has arrived!" The self-proclaimed elite agent reassured, imitating the exact smile Yuuma held while messing with the (already messy) hair of his short protégé.

After watching scenes like this and the uncanny resemblance in attitude between the two, it made people wonder how those two weren't related. That maybe so, but that didn't stop Jin from taking in the little wandering soul under his wing. A little brother, a mini Jin, that was what the ex S-class agent saw in the human neighbor. In other hand, others shuddered at the simple thought of having two Jins roaming free, especially HQ.

In annoyance Osamu readjusted his glasses and closed his eyes to bare the moment. 'Seriously, sometimes I think I'm the adult here' "Actually" he started, thankfully stopping the pair from his antics and returning some seriousness in the matter at hand "We were wondering who the invaders could be this time. Certainly, is not Aftokrator again, like us they need time to recover, so that discards them. But besides said fact, we lack more information to deduce the culprit. Maybe you have some idea, Jin-san."

Time passed where nothing happened, not a single signal of recognition was giving by the older teen. Was he ignoring him or was he really thinking about it? Those were the things Osamu started to ponder at the lack of reaction. Who knew what happened inside that mind of the brunet? Certainly not Osamu who was begging to sweat drop.

"I can´t say that I have." Finally Jin spoke up which it only made the black haired boy sweat more in defeat at the common answer he was getting lately.

"How about your side effect? Does it tell you something?" Asked Yuuma. With his hair now free, he was trying, but failing to somehow appease his wild white locks.

"Like I said before, Yuuma. I can't predict the future of someone I haven't meet yet" Reminded Jin to his young pupil.

"Oh, right"

"But that is something your little heads shouldn't worry about, young ones. Leave the adults take care of that matter." The elite agent said as he restored his action of messing his two adorable kouhais' hair with renew vigor.

'So much for that idea' At the end, nothing was solved they still were as they were at the begging. But somehow it irked Osamu, something was not right he could tell. He wanted to tell Jin but he would only demise it like before. Maybe this time it was easy as it seemed to be, maybe he was just worrying to much like people tended to tell him, he had to think positive and hope for it to be true.

Gradually increasing sound of fast footsteps and rapid pants were heard making their way toward the trio who didn´t even paid attention, immersed in their antics until a small voice called up to them. "Umm… Am I interrupting something?"

The sound of the delicate voice made them break apart from their playfulness, when the trio turned their mismatched eyes were met with a pair of innocent violet eyes peering curiously at them from a small young figure, a girl to be precise, with black short hair and an antenna that was probably one third of her stature. She, like the rest of her squad, wore the blue attire that showed a B-rank agent and a Tamakoma member. In her hands was the responsible for the demolishing ray that annihilated the Bamster, 'the Ibis', which was the same, if not bigger size than her. It was a wonder how the little girl managed to carry a weapon of such magnitude around battle.

"Ah, Chika-chan!" The recognition was instantaneous, not anyone could just pull the cuteness overload like Chika-chan could. With the arrival of a better and adorable target, the two boys were left forgotten, released from they (at least for the older of the two) torment. Nothing surprising when it came to Jin being… well… Jin, who was currently patting his youngest pupil affectionately while said girl just stood there awkwardly without complain.

Osamu couldn't help but heaved a sigh, something he found himself doing lately. With the corner of his eyes he took a peek at Yuuma just to see if, by any chance, he would say something about it. The boy with glasses didn't know why he thought about that as a possibility when he caught the albino's trademark goofy smile. "Jin-san, if you didn't come here to inform us about the attacking neighbor nation. Do you mind telling us the reason for being here?" Might as well put an end to this.

"Eh?" At least it worked for the brunet to regain his focus, maybe they would get to solve things after all. "Can't an elite agent come and check how his cute little kouhais are doing?" Or not.

"…Umm, we just ended the wave of enemies from the institution and the evacuation it's been taken care of." The strategist started to explain "We were about to move forward and aid the other squads with taking care of the other neighbors-"

"That won't be necessary" Osamu's explanation was cut short by the once playful but now serious voice. "Right now, evacuation is more important" Jin had stop his playful act, all severity returning to his posture and reflected in his eyes. With a stance like the one being display, the presents could only implied the worst.

"What?!" The statement had taken all three members by surprise. With another large-scale invasion like this one at a short time, they were sure Border would need all the help it could get. But to stop this soon. Was it really that bad to abandon hope now?

"Ah…No, no! Don't misunderstand me" After seeing the pale and shocked faces of his pupils, he knew he had hinted the wrong thing. And that was how the ex S-class agent found himself trying to amend the misinterpretation with hurried words and furious shake of hands. "What I meant was, with the basic kind of Trion Solders like Bamster and Marmod, the other squad had no problem in discarding them."

"But there were tons of Trion Solders in the city!" Exclaimed Osamu impressed at the effectiveness of the members of Border.

"Yes, there's still waves but nothing the rest of the agents can't handle" Jin reassured the boy.

The three allowed themselves to exhale a relieved sigh simultaneously. Their creative imagination had ran wild right after their senpai's statement, making them see the worst and weirdest outcomes. They certainly weren't happy with Jin right now but were more surprised when it was Chika, the quiet girl of their group who scolded their mayor. "Please Jin-san. Don't scare us like that. Try to speak more clearly next time."

"….Ah… S-Sorry, sorry!" Not even Jin knew how to react.

"If we are not going to the other parts of the city, then what should we do?" Asked Yuuma, a little disappointment for being denied the fun.

"Well you have the evacuation of this school going" Instructed Jin. "Stay here and help with the procession since it's one of the last places to be clear." That would keep them out of trouble for a while. Regardless, knowing their luck trouble would come to them for sure, not the other way around. He could only hope.

"Hai!" Tamakoma-2 agreed at the command, two more willing than the other.

"All right, I'll be going now. In times like this the elite agent can't afford to leave the battle. That's the life of an elite, what can I do?" Jin said. Seriously, this guy, a maniac would be the exact description of the crazy out-loud laughter he was giving.

'How humble' The trio sweat dropped. A step back, maybe two… and a half, just to be sure and at a safely distance.

"I'm off, I'll be counting on you" Those might have been just words, however they held more weight, more meaning to Tamakoma's second squad. While they watched the retreating form of the young adult, growing smaller and smaller with each jump he took, their stances never faulted not even once. No matter what the entrusted task was, the new members would always do their best to accomplish it in hopes that one day they would make everyone of their senpais proud.

Little did they know that they mayors were already proud.

Especially Jin, his minors were growing with each challenge they took. He allowed himself one last glance and when he did, he couldn't be more overjoyed with the sight his three little pupils were giving. Seeing the trio together, standing side by side with each one of their posture radiating determination and their eyes, the tree set of eyes reflecting their inner willpower; it made Jin (secretly) rejoice of happiness, the only proof was the sincere smile escaping his features.

Even so, the moment was short lived as soon as the pair of turquoise eyes set on the small humanoid neighbor. The radiant smile that would melt any fangirls, vanished; now that a sour mood represented with a slight frown, replaced the previous one. Jin couldn't help but feel like he was abandoning his kouhais when they needed him the most, ridiculous he knew, especially with things going as smoothly as his side effect was telling him.

Regardless, the feeling kept nagging him, screaming at him everything was about to go downhill. However this time it wasn't for Four Eyes or Chika, no, they would be perfectly fine; instead the feeling was directed toward the young veteran who was quite capable of taking care of himself.

Right now he had to focus on the important issues to be concern by a simple feeling. So without faltering Jin made his way to the pending battlefield, hoping for the best that everything would transpire okay.

Little did he knew, that was the first mistake to be made that would mark the fate of their beloved neighbor kuohai.

A/N: Well that's that.

First chapter. And the second to come hopefully soon but it takes me ages to write a chapter (with only this chapter, it took me all 3 seasons of Kuroko no Basket) and I have school too . So in advanced, sorry for the slow updates, I'll try to write them as fast as I can.

Read and Review! KuroKapibara out!
