DISCLAIMER: The following story is an unofficial sequel to the fan fiction "Happy end" by Rainbowkittyblossomwings. Read her story first to both avoid spoilers and to help you understand the plot better (although, this chapter is pretty much just a recap of what happened in that story, but it still doesn't do the entire thing justice). It is a story that I highly recommend that you read, as it is personally one of my all-time favorite fan fictions. The emotion, the tension and the characters all help to make that story a one of a kind treasure. And in all honesty, I'm not fully confident that I'll be able to top or even match the same feeling of reading Happy end with this story. But I'll certainly try.

Also, I don't own Sgt. Frog or any of its characters. All characters and names in this story are property of Mine Yoshizaki and Rainbowkittyblossomwings. I own nothing.

PROLOGUE

Journal Entry Number 1: It's happened! It's finally happened! I've just been accepted into the military under my dad's watch! I'm so excited! I've been training non-stop for as long as I can remember, preparing myself for this day. According to my dad, I've been placed under the combat unit and will be leaving for training camp tomorrow. Most of my friends called me weird for wanting to join the military, but just wait until they see me again after a year of training under real Sargents and Generals. I'll be stronger and more energetic than I've ever been! Then I'll show them why being an invader is such an awesome job.

Besides, what do they expect? They know my dad is a high-ranked General. It makes sense that he would want me to be just like him. He may have been a bit hard on me as a kid, but at least now that I'm older I can better understand why. He just wanted to toughen me up. And to think I was such a baby about it, too. Just wait until he sees how strong I'll be after training's over. It'll probably be the happiest I've ever seen him. Heheheh.

But all in all, I'm just happy that I'll finally be living my dream of being a trainee in the Keron military force. Honestly, I'm trying as hard as I can to stay calm while recording this. I'm pretty sure that as soon as I'm done, I'll start jumping around the room like an excited tadpole. Heheh. Well, I better get ready to go. I may be leaving tomorrow morning, but it would still be easier just to get all of my packing out of the way early.

Oh...right. I've already finished packing. Heheheh. I forgot. I did all of my packing before I left to go sign up. I guess I was a bit more excited than I needed to be. Heheh. Well...at least I don't have to worry about it anymore. I still better go say goodbye to my friends. I should probably call my grandma too and tell her the good news. I wouldn't want her to miss my sendoff tomorrow morning. Looks like I've got a lot of stuff to do. I better get to work. Journal Entry: Offline.

STAY OFF OF PEKOPON OR I'LL DO THE SAME TO YOU.

"Who do you believe could have done this?" one of the three Supreme Commanders asked his two partners. The three Keronians stood in a small circle as they all stared down at the mysterious piece of evidence that had been recovered from the third failed Pekoponian invasion attempt. The photo that was taken from the recent accident on the leading General's ship had just been sent to them for analyzing and was sadly getting them nowhere. The blood-written threat was just too vague for them to say for sure who had written it. The leader turned to face his companions.

"It could be possible that this was the work of a surviving Pekoponian. Or perhaps a group of them did this together. It truly is hard to say for sure." he suggested, his partners only turning to face one another with blank expressions.

"Could a Pekoponian, or even many, really have enough strength and willpower to kill off one of our highest ranking Generals?" the third Commander questioned his leader's thinking.

"Sometimes even the most unlikely answer can be the correct one." the leader replied. Just as he had finished his thought, the automatic doors that worked as the entrance to the Commander's headquarters swung open. A single marine colored Keronian came rushing into the room at topmost speed, almost too fast for the doors to open in time to allow him inside. The Keronian stopped in front of them, trying to catch his breath through heavy panting before standing up straight and saluting to them while he spoke.

"Commanders! We have just finished out scan of what's left of the General's body! I'm sorry to report that..." the Keronian swallowed nervously. "...the 'you-know-what'...is missing."

Silence echoed through the room. The three Commanders stared down at the nervous Keronian from the small hovering pedestal they stood crowded on. After several seconds of uncomfortable staring, the leading commander slowly turned his head over to face his left partner, his eyes squinting once their gazes met.

"Send word to every available radio and network station across Keron. Immediately."

"Attention inhabitants of Keron. This is a message from the Supreme Commanders of the Keron Military Force. As of now, the planet known as Pekopon is off limits to any and all invaders hoping to finish what we could not. These Pekoponians are dangerous creatures and must not be allowed to come in contact with any Keronian at any time. So from here until further notice, Pekopon is officially off the map. Any Keronian ship that is caught headed in the direction of Pekopon will be shot down on sight. That is all.

Invasion changes many things. It can permanently alter a civilization's way of life. It can lead to rebellion, hatred, war and death. But for the inhabitants of Earth, they were cursed with all of these things and worse when the Keronians came during the massive, planetary invasion just one year ago. After two years of peaceful living between the Keronians and the humans on the small planet known throughout the universe as Pekopon, the whole of the Keronian army, lead by a ruthless and bloodthirsty General, eventually took it upon themselves to finish what only a single platoon of five below average ranked soldiers could not.

The began by eliminating Japan; the same country where the original invasion platoon, formally known as the A.R.M.P.I.T. platoon, had been stationed ever since they first arrived and had since befriended and grown attached to the enemy. They were each punished firmly and mercilessly for their traitorous actions against the Keron Army shortly after they were captured, with each punishment set into motion and supervised by the General herself, who also happened to be the mother of the platoon member named Giroro.

Keroro, the Sargent and leader of the platoon, was immediately stripped of his rank and sentenced to life as a puppet, forced to watch through the eyes of a clone copy of himself as it hunted down and murdered many of the Sargent's close companions.

Tamama, the Private, was sent back to Keron under orders of the General, where he was forbidden from returning to both Pekopon and the Keron army. He was later secretly recruited back into the military under the new name "Matata", hoping to seek vengeance on his past love interest Keroro after the Sargent's clone rejected his feelings towards him, breaking both his heart and spirit.

Dororo, the Lance Corporal and former Keron assassin, was never found by the Keronian forces. However, after dedicating his life during the invasion to protecting the helpless and weak from his own kind with the help of his life partner and ninja friend Koyuki, he was eventually discovered by the Keroro clone and almost lost his life in the process. However, although his life was spared, his and Koyuki's adapted daughter, who they had chosen to take care of after witnessing her parent's death, was lost in the crossfire. Unable to deal with the pain of her daughter's death, Koyuki quickly committed suicide shortly after realizing the truth, leaving Dororo permanently alone and with nothing to hold onto.

Kululu, the Sargent Major and science officer of the platoon, was recruited to help in the invasion during the first stage of the attack on Pekopon. He gladly took the offer and worked along side the General during both the invasion of Pekopon and the war on Planet Angol, which was set into motion when the young and naive Angolan named Mois, who had prior to the invasion worked along side the A.R.M.P.I.T. platoon, struck the Keroro clone out of rage, breaking the peace treaty that the Keronians and the Angolans had kept for so long.

However, his compassionate side eventually got the better of him and he began refusing the General's orders unless he was allowed to see the Angolan girl, Mois. Having gone against Military protocol by denying a superior's orders, he too was sentenced to be tortured as punishment. And as ordered by the General to help add insult to injury, he was placed into the exact same cell as Mois. For weeks he stayed there beside her, growing more and more attached to the naive girl as time passed. But when an unfortunate accident occurred during a drug hallucination caused by a poisoned plate of food, Kululu, believing that it was one of his old enemies, unintentionally murdered Angol Mois during the trip and woke up moments later drenched in her very blood.

With vengeance as his new priority, Kululu stole not only Mois' planet-shattering Lucifer Spear, which he quickly used to escape, but he also took out her very eye and attached it to his own socket, believing that he could hear her voice telling him to do so even after death.

Finally, Giroro, the Corporal and weapons specialist of the platoon, was the General's first target. Knowing of her son's choice to abandon the invasion after falling in love with a young Pekoponian by the name of Natsumi Hinata, she made it her main priority once she reached Pekopon to hunt down Giroro and sentence him to the worst torture possible. However, before she even made it to Pekopon, Giroro's older brother Garuru had already discovered their mother's plans and warned his younger brother of her arrival. With this small advantage, Giroro managed to save Natsumi from certain death and hide her away in a secret survival shelter designed by Kululu.

Shortly afterwards, Giroro was tracked down and punished by the Keron army just as the General had hoped. As punishment, his mind was wired into a computer simulation where he was forced to watch Natsumi, his lover, endlessly die for what was designed by the General to feel like decades. After a few months in the simulation, all traces of Giroro's sanity had all but been destroyed. Once he was released, he was but a shell of his former self. He only wanted death. He only wanted to be with her again, believing that she truly was dead. The General, having no pity for her mentally damaged son, sent him down to Pekopon, ordering him to eliminate any remained Pekoponians that may have survived the invasion, promising him the relief of death if he complied.

By the end of the first year since the invasion begun, the A.R.M.P.I.T. platoon and the relationships they had made with their Pekoponian allies over the years was no more. Their lives had become hell on Earth and it seemed as though there was no turning back. Mankind was on the verge of extinction. The Keronians had taken control of everything and were close to destroying all traces of human existence. There was no chance of survival for Earth anymore. All hope was lost.

But eventually, through many trials and many emotional and physical challenges, things seemed to begin looking up for the now departed A.R.M.P.I.T. platoon once again. Through the help of an unknown being from below the sea, Keroro was able to break free from his prison and managed to track down Natsumi before the Keron army did. Having discovered that she was alive, Keroro left to try and find Giroro and bring them both together once again.

Tamama, after spending several months on Pekopon hunting survivors, soon ran into his former Sargent once again, where he was let in on the truth about what had happened to Keroro and how the heartbroken Private had been rejected by a clone copy instead of the real thing. Joining sides with Keroro once again, the two reunited Keronians hunted down and murdered the Keroro clone as payback for all he had done.

Dororo, having grown a deep hatred towards Keroro for what his clone had done to Koyuki and his adapted daughter, he too eventually was found by Keroro and Tamama, where he immediately began attacking his former best friend with the full intention of killing him. After finally striking a death blow on the Sargent, he was only able to reclaim his thoughts once Tamama explained that it was a clone that had killed Koyuki and not Keroro. Realizing the error of his ways, he quickly went to work on attempting to revive Keroro using an ancient and forbidden ninja technique that transferred Keroro's injuries to himself. After stating his final request to Keroro to never forget him, the blue ninja quickly died in place of his friend, happy to know that his dear Koyuki could finally rest in peace.

Kululu, after fully taking control of Mois' spear, believed that he was happy now that he and Mois could be together for an eternity, but after a few months of attempting to destroy the planet by request of Mois's voice, he eventually realized that he could not go on living without her entire being by his side. While falsely turning back to his original job of assisting in the invasion alongside the General as a way to reclaim Mois' corpse, Kululu soon found himself back together with the rest of his now reunited platoon. With their team joined together once more, the A.R.M.I.T. platoon made it their new duty to put an end to the Keronian invasion once and for all.

Giroro, having been driven insane through his torture, met his older brother Garuru while he was on Pekopon and wrongfully murdered him when he tried to convince the ill minded soldier that Natsumi was still alive. However, with his last dying breath, Garuru managed to leave his brother one final message, which he wrote in his own blood, that he knew would give Giroro at least some kind of hope that not all was lost for him. But it was not until Giroro met Keroro that the truth about Natsumi's safety was finally beaten into him. Literally. As ordered by Natsumi, Keroro used all of his strength to give Giroro a massive smack across the face. After hearing Keroro's words "That was from Natsumi", Giroro was finally given the small salvage of hope he needed to clear his mind and realize what was real and what wasn't.

After finally reuniting with each other, Keroro, Tamama, Kululu, Natsumi and Giroro were ready to begin fighting back against the invaders. Many months of harsh survival passed by before they eventually made a shocking discovery; Natsumi was now pregnant with Giroro's child. After hearing this news, Giroro finally decided that he was through with waiting for the right opportunity to finish the invaders off. It had to end now. For now he had not only Natsumi to protect, but a child as well.

They made their final move. They attacked with all they had. Their spirits and their morals were put to the ultimate test. With one another by their side, they soon drove most of the Keron army to its knees. Giroro personally tracked down his mother and, after dueling with her in one of the toughest battles of his life, put a well deserved bullet straight through her head, ending her life of tyranny and torture once and for all. With no one to lead them, the remaining Keronian forces drew back from Pekopon and returned home without a second thought.

It was over

A year passed on the quiet planet of Pekopon. The invasion that drove the entire planet to extinction was long from being forgotten, but the few remaining lives that still resigned on the empty world had, for the most part, moved on from what had happened only twelve months prior. They were ready to leave behind the losses that were given to them by the immensely tragic event that had changed each of their lives for both better and for worse and finally look forwards towards a bigger and brighter future.

Giroro and Natsumi built themselves a new home and chose to spend the rest of their lives together their as a married couple, raising their son Teri and searching the remains of Earth for any survivors. Keroro chose to go back to his old job as house cleaner for Giroro and Natsumi, along with taking up the job of babysitting Teri whenever Giroro and Natsumi went out looking for survivors. Tamama continues to further his relationship with his former Sargent while also running his own candy store on the side to attract alien customers who may pass by (though, he doesn't get a lot of business). Kululu, however, never got over his affection for Mois and, after being unsuccessful in his mission to retrieve the rest of her body, quickly disappeared after the invasion ended. His whereabouts remain unknown to this day.

For some, the damage caused by the invasion was just too great and had left a permanent stain on their lives that could never be simply looked over and forgotten about. But for others, the very same accident that had affected their lives in their own ways was slowly losing its grip on them through the long and harsh span of time. They were finally ready to move on.

For in a world with a future that seemed nothing but bleak, there were some who managed to find a small light of hope somewhere along the way. And through that hope, they had found something that they had never expected to find after so many years of nothing but pain and misery. They had found something to care for once again. They had found something to make their lives worth living.

They had found their happy end.
