CHAPTER 5

Fuyuki stood in front of Keroro, looking at the various corridors around them worriedly. "Shouldn't we go after Nishizawa and Alisa?"

The green haired girl crossed her arms. "Not really. We'd probably just get lost. Look, the Kiruru seem to have disappeared, so we should just wait here, Lord Fuyuki."

"Ok…" Fuyuki nodded. The Sergeant was probably right. Still… The eerie silence of that tower had returned, but, even so, he couldn't hear any footsteps.

Fuyuki sit on the floor, and soon Keroro did the same, stretching her legs alongside it. He observed the green haired girl's face for a while. "It's just so weird… The sergeant's way of speaking and mannerisms generally haven't changed much… but still… lately, I haven't felt really at ease next to him…eh… her… " Fuyuki stopped, distracted when Keroro suddenly blinked and stared directly at him.

"Any problem, lord Fuyuki?" She asked curiously.

"It's nothing." Fuyuki said, scratching the back of his head. The silence was finally dispelled by the sounds of footsteps hitting the metallic floor tiles.

Keroro and Fuyuki got up, and before long, Alisa and Momoka returned to the intersection. It almost seemed like they had just awakened from some bad dream. There were no Kirurus anywhere and no one was even hurt.

"Gero?!" Keroro pointed at their foreheads.

"There's something here?" Momoka touched her own forehead.

"A Y mark, like this one." Fuyuki said, touching the faint symbol on his head.

"Can you remove it, daddy?" Alisa wondered. The black alien resting on top of her head created claws and covered Alisa's mark with them. However, when he moved the shadowy mass away from her face, the mark was still there.

"This isn't a normal mark… I can tell that much. There's nothing I can do to remove it as it is currently." The voice coming from Alisa's black cat ears complained. He didn't like that interference. Even if it had no real effect up to that moment, that mark was obviously meant to do something. However, removing it was beyond his powers.

"Sergeant, the door is open, we can go back now." Fuyuki had returned, accompanied by his sister, who also had a Y on her forehead.

"I still need to find an important thing here…" Keroro replied weakly. There's no way the other ones would stay there after that incident.

"We can return later, leader." Kururu's voice echoed in Keroro's ear, just low enough so that the other ones couldn't hear anything. "Ku, ku, ku, I've discovered something quite interesting about those Kirurus."

It almost seemed like what had just happened was just a bad dream. One by one, each person reappeared, completely untouched, besides the Y on their foreheads. Quickly the entire group had been reunited right outside of the tower. The Kirurus had completely disappeared and everyone besides Keroro had had been unconscious for a few minutes and received a Y on their forehead, but, otherwise, everything was fine.

"There aren't more of those creatures here anymore." Alisa said. "I'm going somewhere else now. Fuyuki, don't you want to come too?"

"Sorry, Alisa, but it's already late, we're going home now, right, sis?" Fuyuki backed away from her. She had no common sense about some matters.

"Huh… That's right, lord Fuyuki!"

"So, after all, we couldn't find any special weapon here besides those berserker Kiruru. Hmph. Useless, like always, Keroro." Giroro grunted, scowling at her incompetent leader.

"Erase this thing, stupid frog!" Natsumi complained, already back in her yellow dress, pointing at the Y on her forehead.

"This place is just boring!" Momoka complained, before silently adding to herself "and I couldn't even stay alone with Fuyuki!"

"Come on guys. Don't forget to avoid any strong emotions. We don't want to feed another Kiruru!" Keroro tried to calm the air down, but failed completely.

"Either way, there's no reason to stay here anymore." Kururu interrupted the party, carrying a smirk. "Why don't we all just return to Japan right now?"

"That's a great idea, Sergeant Major Kururu!" Keroro went forward, raising her hand to the skies. "There's nothing to do here anymore!"

"The stupid frog… giving up so easily?" Natsumi questioned. Keroro's attitude was obviously weird, but no one wanted to stay there any longer and just went along with the plan this time. A few hours later, after the sun had set and the moon illuminated the night, the keronian transport craft returned to the tower, landing in the same location.

Its front gate opened and Kururu came from inside. "Alright, leader. I'll make the preparations… ku, ku, ku!"

From inside the transport plane, Keroro, covered in shadows, saluted the Sergeant Major, grinning diabolically. "Everything is in your hands now, Sergeant Major Kururu. Pekopon will be ours… in 24 hours! Gero, gero, gero!"

/KeroGirls – 05: Kiru-Y strikes back! Yes, sir!/

A purple keronian stood alone in the middle of a sterile gray corridor, looking at his home planet through a window. The green planet slowly became smaller and smaller as the ship distanced itself from it.

That particular keronian carried an eternal scowl, like Giroro, but his was even more accentuated due to his helmet, covered his eyes partially, keeping a permanent frown on his face. If that weren't enough, his eyes were all covered by yellow lens, giving him quite an aggressive look for a keronian. Like Giroro, he kept a belt across his body, rather than wearing an emblem on his belly.

Yet, even through all those masks, the heaviness on Garuru's eyes was visible. After staring through the glass alone for a few minutes, he deviated his gaze towards the corridor as he heard someone approaching. It was Chief Medic Pururu, who was just passing through, reading a small report.

"Chief Medic, how was your visit to Pekopon? You didn't talk much after returning." Garuru said with his usual deep voice, without even turning to look at the pink keronian.

"There was nothing strange there. Your bother was healthy too." Pururu trembled slightly. "Why the sudden interest?"

The platoon leader turned around, facing Pururu directly. "Haven't you heard the news from the HQ? They're preparing the new special forces team to take over the Pekopon invasion operation."

"They… are…?" Pururu staggered, looking in shock at her leader.

"Do you know why?"

"No…" Pururu nodded negatively, sweating nervously.

"Because they disappeared completely 11 days ago." Garuru's gaze was sending chills to Pururu. His pupils were perfectly visible through his yellow lenses. "You returned from the last check up there yesterday, wasn't it, Chief Medic? Shouldn't you know the situation in that front better than anyone else?"

"Yes, lieutenant Garuru…" Pururu lowered her head.

"So, what are you hiding?" The platoon leader asked, looking harshly at his suspicious subordinate.

"Zeroro has disappeared?!" A whispering voice reached the two keronians as a third soldier's presence in that location was finally noticed. He was a keronian who had the entire left side of his body replaced by cybernetic components. His organic half had a light gray tone, with several white bands covering his mouth. His metallic body was mostly featureless, just a metallic version of a keronian's silhouette, the only exception was the battle claw and spiked armor on his arm, features that came straight from an the battle armor of keronian assassins.

To complete his weird figure, he had black eyes with red pupils – even though one might think that it was just a consequence of his implants, those were actually natural colors. In spite of that grotesque figure, he had gone completely unnoticed in that corridor up to that moment. He turned his back to the others, quickly dashing through the corridor.

"Lance Corporal Zoruru! Wait!" Garuru yelled, but got no response from the assassin, who went on with his obsession with a rematch against the blue ninja of the Keroro Platoon.

"Seriously," Pururu said, walking around Garuru with a completely serious face, "each member of this platoon is extremely capable, but don't you think we're lacking on actual fellowship?"

"What?" Garuru calmed down as his pupils finally vanishing.

"Each member of this platoon mostly lives in their own world. Outside of missions, we barely interact, don't you think so? Everything ends up well usually, but don't you think the Lance Corporal's attitude right now shows that this can be problematic too?" Pururu continued speaking, hoping Garuru would just go along with it and ignore that other problem.

"It's true…"

"Then, why don't we take a vacation together? We could go to Planet Doinaka or Planet Maron…"

"You might be correct, Chief Medic…" Garuru grinned "However, I think there's a more interesting place for such vacation…"

The Chief Medic looked worriedly at her leader… "You don't mean…"

"Pekopon." Garuru finished his sentence, crossing his arms. "See if you can stop Zoruru before he tries to go there by himself, I'll talk to the superiors to make this arrangement."

"O-ok…" Pururu saluted her leader. The situation seemed to be worse than she had thought. Did the Keroro platoon even know about this replacement order? They didn't really seem to be very worried about that situation back on Pekopon…

/

A new day started, however one person refused to get up. A green haired girl yawned, still lying on her bed. She was dressed in pajamas, green pants and shirt, alongside a yellow hat. The center of the shirt was white and had a yellow star drawn on it, resembling a cosplay of her keronian body. Curiously, or maybe not, her hair was still tied even then. "I need to sleep more, don't bother me now…"

"You're really useless." Giroro concluded. She was standing in that room, dressed in her usual uniform, looking at her leader, who was still sleeping peacefully. The Sergeant had a peaceful face while sleeping and it only annoyed her even more. She was useless, coward and had ordered the construction of the weapon that had turned them into pekoponian girls.

Suddenly, as if out of nowhere, an idea dawned on her mind. She stared at the piece almost magically keeping her hair in place, the Keron Star. The symbol of the leader of the keronian invasion troops. Keroro didn't deserve it. Yet, in her arrogance, took it for granted.

"Yes," Giroro murmured, crouching next to Keroro's bed, looking intently at the star shaped bow "I'm the one who deserves this." Unnoticed to her, the Y on her forehead was glowing brightly. She raised her hands, almost touching Keroro's hair, but stopped. "Wha-what am I thinking!?" Giroro asked herself, before hurriedly leaving the room.

"Did anyone call me…?" Keroro just drooled, still half asleep.

/

Elsewhere, Natsumi approached a bus stop next to a large square. She had awakened that day somewhat indisposed, but decided to go meet her friends anyway, in spite of that strange mark in her forehead. She wore a dark blue miniskirt and a weird combination of a short sleeved orange shirt worn over a long sleeved yellow turtleneck.

The plaza was relatively empty. There were a few people walking around, it wasn't crowded at all. Two girls around Natsumi's own age were there waiting for the redhead. One was Satsuki, dressed in a jeans and a green jacket, the other one was a girl with long black hair and a light, almost sleepy, eyes, Yayoi Shimotsuki, who sported a sleeveless dark blue dress. The later had a fragile physique and clearly wasn't as much into physical activities as her two other friends. Both had been Natsumi's friends years before she had ever met Keror and the other aliens, and they still hanged around together, though she hadn't ever told them anything related to the aliens.

"Natsumi, what's this thing on you forehead?" Satsuki asked while she looked curiously at the Y mark lightly burned on her skin.

"Great… Thanks very much, stupid frog…" Natsumi muttered angrily. Why couldn't they have noticed her new clothes rather than that stupid mark?

"Hm… I think I've seen something like that before…" Yayoi tried to remember something, but just couldn't. She wasn't quite sure what it was supposed to be, but the weird mark bothered her somehow.

"Shut up! You're annoying!" Natsumi complained, just walking past the other girls. She really didn't want to make up some stupid excuse for that mark. A faint glow appeared on the mark, but it was almost imperceptible due to the sunlight.

"Eh…?! What's up with that attitude?!" Satsuki protested. "Let's go somewhere else, Yayoi!"

"Hm… There's something weird here…" The long haired girl stood in place for a while, but ended up dragged by the other girl. Unnoticed to both, another "Y", almost like a small burn, appeared on Satsuki's forehead.

Natsumi looked over at a small ticket for a live presentation from 623 that she had bought, and thought about going after her friends again, but quickly dismissed the idea. It'd be fun even without them. They were just an annoyance anyway.

Just after she started heading to the location, a sudden cloud of smoke blocked burst forth out of nowhere. Her eyebrows twitched. Why did Koyuki always make those extravagant entrances?

The ninja girl leaped from the cloud of smoke, gathering attention from the passersby around them. "Na-tsu-mi! Good morning!"

"That idiot…" Natsumi complained. "Go bother someone else!" The redhead yelled, leaving behind a shocked Koyuki.

"Natsumi…?"

"What was that all about, Koyuki?!" Dororo appeared almost out of nowhere, standing close to Koyuki herself. She was dressed in blue overalls and a plain white shirt. She was also wearing a small gray scarf around her neck and gray boots, looking like a person who had just arrived from a farm, though the medical mask covering her mouth didn't fit well with that image.

"Dororo…" Koyuki had no reaction. She was just stunned by the aggressive behavior from the usually serene ninja.

"What are you trying to do? Making a fool of yourself in front of everyone?!" Dororo glared at Koyuki. "Ninjas learn to be walk in the shadows and hide their presence to be stealthy, not to announce their presence everywhere, Koyuki." The Y mark on Dororo's forehead was radiating an unseen glow as she walked right past her friend.

Koyuki was just stunned, standing in the entrance alone for a few moments before the flow of students returned to the school's gate. Her own Y mask glowed, and quickly her stunned expression became a devious grin. "Stealthy, eh?"

"What…?" Dororo looked behind her perplexedly, but Koyuki had vanished. "My words just now…" The blue haired ninja said, looking at her own hands. "Those words weren't mine…"

Meanwhile, elsewhere, a lone girl dressed in a black French maid uniform stood next to a crater, glaring insanely at it while grinning. "You asked me to clean this, didn't you, PAUL?!" Tamama yelled angrily, facing backwards suddenly and pointing at the source of her anger, Paul Moriyama.

The old butler stood firmly, looking sternly at Tamama. He stood among broken walls and floor tiles, but his suit was basically untouched, "Everyone in the Nishizawa Peach Group must follow their path and built their own lives. There's no room for friendship or charity. If you lost your mascot role, you must find a new path!"

"Heh… I'll find my own path, Paul…" Tamama lowered her head, grinning as a dark aura enveloped her body, a sphere of black energy solidifying on her right hand. Contrasting with that shadow, a Y glowed on her forehead. ",as Nishizawa Group's… No… Pekopon's… Ruler!"

"If that's how you want…" Paul distanced his legs from each other and shouted a battle cry while a red aura enveloped his own body and his pupils vanished, wind blew around him creating a small circle "Come!"

The two fighters rushed towards each other, vanishing into blurs right before an explosion covered the entire battlefield.

Back in a normal neighborhood, Fuyuki, in his casual clothing, a white shirt and blue pants, observed a ruined wooden house in the middle of an otherwise average neighborhood. Inside the building, a girl dressed in a white kimono was standing, looking around for a while before nodding disappointedly. Her figure, including her long black hair, was translucent and her clothes were unnaturally clean, a fact that became obvious when contrasted to the dirty ruins of that wooden house.

"Thanks, ghosty!" Fuyuki bowed to the ghost girl. Even though she was supposed to haunt his home, sometimes it seemed like everyone forgot that detail, even the ghost herself.

As soon as the image of the girl disappeared, Fuyuki lowered his head. That was supposedly a haunted spot, but he was disappointed to learn that it seemed to be just a sham. Of course, he didn't need to see a ghost there to verify the existence of ghosts or anything like that, but sometimes it seemed that every supernatural occurrence in the entire world only happened around him, and, when they did, they happened all the time, just removing the importance of those events. The ghost girl that had just left… When he first learned about her, it seemed interesting, but afterwards she was awfully, normal, besides one or two days. The same could be said about the Keroro platoon… What once seemed special, interesting, became routine.

He liked the occult due to the mystery that surrounded it and the thrill of uncovering the unknown… However, sometimes it seemed like the entire world had nothing to offer him anymore. Not only was the world depressingly normal, it just disgusted him how often humans made up such blatant lies just to promote themselves.

"Humans are rotten, the world is rotten."

"What?!" Fuyuki abruptly stopped after those words came into his mind. What was that all about? He was disappointed, sure, but he didn't even sound like himself! Had he just been possessed by a ghost from that house?

"No, she said that there was nothing there." He concluded, quickly focusing on his next suspect. "Could it be this mark...?"

/

Back in the Hinata residence, Keroro had finally gotten up. She was inspecting the strangely empty Hinate residence.

"What's this all about?!" She complained after looking at the empty living room. "I get up a little late and everyone disappears!?"

"Un-cle!" Mois came from the kitchen, holing what looked like a plastic green gun, patterns of yellow stars and blue circles spread all over it. She was in her human facade, dressed in the blue skirt and blue blazer of some school uniform.

"Lady Mois!" The green haired girl calmed down after finding the planet destructor, "So, there's someone still here! What happened to everyone else?"

Mois smiled. However, there was something different, rather than a comforting radiance, Keroro just felt shivers while looking at her face. Somehow, it seemed like there were shadows projected on her face, accentuating her eyelashes and mouth. There was just something… disturbing… about her.

"I think you've already been gone for enough time, Uncle! You could say, time to return?" Mois said, raising the "you're one of us" gun and pointing it at the green haired girl standing before her.

"Hu… Lady Mois… don't you remember what happened to Giroro?" Keroro's smile broke, but she lightly held the gun. Angol Mois couldn't be serious!

"I do! But… you could say a dead Uncle is better than no Uncle!" The Y mark on her glowed strongly.

"What…? But I'm right here!" The Sergeant raised her hands defensively, stepping away from the obviously weird Mois.

"You're uncle, really?" Mois suddenly started waving the weapon around with one hand and placed a finger next to her mouth with another. "Are you 2 feet tall?"

"Currently, no, but…

"Is your skin green?"

"Huh… Does the hair count?"

"Do you go crazy when the humidity gets high?"

"Of course-… Wait… now that you mention it… I didn't change that other day…"

"Do you have manly thick eyebrows?"

"Wait!" The green haired girl protested, "I never even had eyebrows in my real body!"

"You don't even know Uncle Keroro, so you aren't him! You're a fake!" Mois said, firing a shot towards Keroro, who jumped over a sofa, landing next to a wall.

"But, don't worry, uncle! I'll fix you right now!"

"What's this all about!?" The Sergeant complained while she ran alongside the wall, escaping from several shots. She rushed outside as soon as she could, slamming open the glass doors and running right to a red tent located outside.

"Corporal Giroro! Corporal Giroro! You're in here, right?! Mois is crazy, help me!" She shacked the tent repeatedly, however, the only reply that she received was a bullet flying from inside the tent almost hitting her head.

"Don't make me kill you right now, Keroro!" Giroro's voiced threatened her. "I already have enough reasons to rip that Keron Star from you, don't give me any more!"

"Gi-Giroro?!" Keroro looked behind just in time to see Mois aiming the special weapon while holding a devious smile.

/

Fuyuki was returning home, still worried about that event from earlier, when he suddenly stumbled on someone else.

"I'm sorry." He excused himself to the girl and was about to continue on his way, but quickly stopped when he finally noticed who was standing in front of him. "Alisa?!"

The dark hunter was dressed in a female school uniform of Fuyuki's school, still keeping her black leggings under the uniform.

"Why are you dressed like that?" Fuyuki wondered, somewhat surprised.

"Supernatural events always seem to follow you around. So, we'll stay in this city for some time." Alisa said, pointing at Fuyuki. "Why? Does it bother you?"

"Ah… no. Not at all!" Fuyuki smiled nervously. Alisa could be so weirdly direct sometimes.

"But it bothers ME!" Momoka appeared out of nowhere, dressed in a pink battle suit. The armor covered her chest, forearms and ankles, revealing a skintight white jumpsuit under it in the unprotected parts. Her right hand was covered by a cannon shaped similarly to Tamama's keronian head rather than a metallic glove. Her eyes were glaring intently at Alisa, revealing that her hidden personality was in control at the time.

Both girls exchanged glances, sparks flew between them as their Y marks glowed.

"Their marks…" Fuyuki noticed their shine, but just remained still.

"Alisa, is there a problem?" The creature shaped like cat ears, lying on Alisa's head, asked, after noticing her abnormal behavior.

"This girl… irritates me." It was Alisa's only reply.

"I'm not fond of you either, monster!" Momoka replied in defiance, aiming the Tamama cannon at the other girl.

"Stop!" Fuyuki stood between them. "Don't you see that there's something weird going on?! You aren't like this! It's Kiruru's mark!"

The boy looked at Nishizawa. "You remember, don't you? Something like this happened before! You too, Alisa! I didn't know you at the time, but you remember the "Revocommunication, right?"

"You mean, when the humans got X marks in their bodies and received telepathy and mind reading during a few days? That was related to Keronian activity?" Nebula, Alisa's adoptive parent, asked, its white eye appearing inside the cat ear, looking at Fuyuki curiously.

"Yes! I don't understand what's happening right now very well, but it must be related to the Kirurus too!"

"If-if you say so…" Momoka lowered her weapon while her eyes stopped glaring insanely. Alisa just continued as she was before, though deviating her sigh from the other girl.

"Help me!" Keroro ran through the streets at her highest speed, but Mois could still keep up with her while wearing her human guise and firing sporadically shots with the transformation weapon, though they just seemed to hit the pavement itself.

"Daddy."

"Understood, Alisa." The ears from her head extended themselves and quickly morphed into huge shadowy hands which swiftly grabbed the two girls.

"Sergeant? What is happening here?" Fuyuki asked, observing the ponytailed girl who was placed next to him, while Mois uselessly tried to break free from Nebula's grasp.

"Is this green haired girl that green keronian? Sergeant Keroro?" Nebula wondered curiously.

"Yes, that's him… or her…" Fuyuki answered embarrassedly. "It's a long story, so let's talk about that later."

"Lord Fuyuki?! You're normal, right?!" Keroro grabbed Fuyuki's shirt as soon as the dark hand released her, "Giroro and Mois are crazy!"

"Wait… You don't know why this happened, Sergeant? I thought it might have something to do with the Y marks." Fuyuki said, pointing at the mark on his forehead. Keroro looked at it and quickly just staring at it in disbelief.

"Huh… Could you release him?!" Momoka shoved the green haired girl out of the way, looking at her angrily. "So, what do you know about this mark?!"

"Gero…! I should have called Kururu as soon as I got up today… She was supposed to analyze those Kirurus…"

"Then do it now, airhead!" Nishizawa yelled, shacking the Sergeant repeatedly.

"Ok… Let me try it… Sergeant Major Kururu! Sergeant Major Kururu!" Keroro placed a hand next to her ear and asked repeatedly, obtaining an answer after a few seconds of static.

"Ku, ku, ku… Finally remembered, eh, leader?" Thousands of kilometers from that place, Kururu was sitting comfortably in a dark room surrounded by monitors everywhere. There were no actual lights, the only illumination came from the monitor screens that were floating everywhere in that room. Several mousse, keyboards, laptops and entire control panels were lying on the floor and Kururu herself was a mess, her hat fallen on the floor, leaving her long unbraided hair, that usually remained hidden inside it, falling all over her.

"So, have you already taken control of the Kirurus?"

"Not completely. I can't change their basic functions, but I can direct their targets, control their general movement, if the unit hasn't fused yet, and could even turn them off right now." Kururu answered, looking at a monitor that showed several "y" spread around a world map, at least half of them over Japan.

"Anyway, leader, I've got news for you, these aren't normal Kirurus. They're Kiru-Ys."

"Gero? What does that mean?"

"They're ancient prototype Kirurus that were forbidden by the space police. Unlike the other Kirurus that feed on emotions or were simple battle machines, this one was designed to mimic and combine with various species. It was originally created to invade through mimicry."

"Invasion through mimicry?" Keroro said it aloud, attracting unwanted attention from the others who were unable to hear Kururu's voice.

"This kind of Kiruru is able to absorb and amplify selfish thoughts of one's heart, but only after becoming one with its target, fusing with it and hiding in its own subconscious. The intended result would be the target destroying itself over time. Officially, it was used only once by the ancient Keron Army. They were sent to some unimportant planet inhabited by a race similar to Pekopon's dinosaurs. However, the test ended up in a disaster which was erased from Keron's history books. Ku, ku, ku…"

Kururu continued. "Kuh… these Kirurus originally meant to create confusion and strife in their test operation, provoking the creatures to destroy themselves, however, somehow, in less than one year, it transformed itself alongside the race it had infiltrated, developing a powerful civilization that quickly became a galactic menace. Thanks to its great adaptability, this Kiru-Y revealed itself to be not a weapon to invade through mimicry, but one that could invade through evolution."

"Evolution…?" Keroro whispered.

"Could you say something, stupid?! We can't hear anything!" Fuyuki strongly pushed Keroro's arm, staring intently at her face.

"Stupid…? Lo-lord Fuyuki?" Keroro was startled by Fuyuki's expression. His angry gaze chilled her entire body. They resembled the angry eyes that she had seen before a few times when Fuyuki was extremely angry, but these seemed to have come nowhere and seemed even colder than usual.

The Sergeant looked at the Y mark in his forehead for a few seconds, pondering her next action. "This Y mark in your heads… it means that a Kiruru has fused with you." Keroro silenced afterwards, looking down.

"What?!" The collective reaction was of surprise, even Mois stopped struggling after hearing that. Afterwards, everyone stood still, waiting for the end of Keroro's dialogue.

"Anyway," Kururu's voice echoed again in Keroro's head, "The Angol family had to act and destroy that entire race to protect the universe. However… there was still another problem. This Kiruru wasn't originally developed on Keron, but, here, on Pekopon, by a previous Keronian invasion force. After the incident, they tried their best to seal and hide this tower from the outside world, alongside the remaining Kiru-Y prototypes. They also left behind various bases and other objects on Pekopon… including…"

"…the 2 other ancient Kirurus that we found before?" Keroro inquired.

"There were 3 ancient types, actually, but that's it. It seems that their protective measures couldn't last forever. This batch of Kirurus had reactivated by themselves somehow and started a slow infiltration of this planet. When we broke through the Anti-Barrier, the system was fully reactivated, and, right now, there are thousands of Kirurus spreading themselves all over this planet."

Kururu grinned. "One of them is inside that Angol clan girl right now. I suppose you've already noticed it… Her abilities will eventually be analyzed and passed on to the other units. Not even the Angol clan would be able to oppose us if we just let the Kirurus continue their operation. Basically, if we continue this invasion attempt, we could conquer not only Pekopon, but the entire universe. So, what do you say, leader? Ku, ku, ku…"

"Conquer… the universe…?" Keroro just gasped while Kururu's revelation got through her. "Wait… are you really Kururu?!"

"I'm not stupid enough to mix up my own emotions with the ones from some android. Too bad others can't do the same."

Keroro glanced at Fuyuki, whose expression had returned to normal, without the weird focused eyes from before. She sighed. "Deactivate the Kirurus, Sergeant Major Kururu. This is an order." Keroro said.

"What…? I don't think I heard that very well."

"I'm telling you to deactivate the Kiruru army, Sergeant Major!" Keroro shouted, cutting communications right afterwards.

"Ku, ku, ku… Are you serious, leader? Very well…"

"Everything will be okay, I guess." Keroro smiled weakly to the group.

/

Giroro was standing still in a small corridor in the first floor of the Hinata residence, looking at a closed door in front of her.

The door itself was nothing special, just a usual wooden door. The only notable detail was a small board with the word "Winter" hanging on that door. Yes, that was Fuyuki's room, where the strongest weapon of the Keronian army was kept hidden most of the time.

The corporal sighed as she opened the door. She shouldn't need to do this. No one was there, as expected. She inspected the room. There was a small table with a laptop on it, a bookshelf with various occult related junk, like a red skull and various books, a bed next to the window, a closet at the opposite side and a some drawers beside it.

The only places inconspicuous, but big enough, to hide the Keroball were probably the closet and the drawers beside it. She chose the closet, raising her arms to open the door but stopping immediately afterwards.

She intended to steal the Keroball for herself, Keroro had no right to be a leader anymore. "This is her… damn it! HIS fault." Giroro bit her own lips. She really hated when she caught herself referencing any of them with female nouns. Unknown to Giroro, the Y mark on her forehead had an incandescent red glow…

/

Kururu sighed. Keroro continued to disappoint her at every opportunity. Well, no, she couldn't call it a disappointment. After all, that answer was perfectly predictable considering her leader's attachment to the Pekoponians.

However, Kururu was different, or so she told herself. A simple look at the monitor screen floating right in front of her revealed that she was about to follow Keroro's orders and stop the Kiruru, a simple prompt in that screen was everything that remained in the way.

"You aren't special, Kururu," a familiar voice echoed through the room, startling even the keronian genius. The face of a recognizable white haired teen suddenly appeared in front of the monitor, staring right into Kururu's eyes, piercing through her glasses.

"You…!?" Even if only for a brief moment, Kururu couldn't hide her surprise, pushing the chair she was sitting in slightly backwards when the figure emerged. The Mutsumi that was standing there was identical to the one that Kururu had met shortly after arriving at Pekopon, wearing the same open green blazer, white shirt, gray pants and a white knit cap.

"You aren't any different from the others," Mutsumi continued, smirking. "Just like the other Keronians, you got used to your life on this planet. To this routine." He talked while walking around Kururu's chair, while she followed his movements intently.

"Ku, ku, ku…" Kururu laughed, her hand resting near her mouth, any traces of surprise in her face having already vanished. "What are you trying to do? Did you really think I'd be moved by that… Kiru-Y 01?"

"You got me…" The fake Mutsumi said, shrugging his shoulders, but still keeping the facade. "However, what I've said isn't a lie. According to my analysis of your own memories, Sergeant Major, you were someone that always could live by yourself, a self made man who rose through the Keronian army rankings in an unseen fashion. Yet, after arriving on Pekopon, you actually got attached to 'others'. The Keronians, the girl from the Angol clan, the Hinata kids… and, of course, there's the one person you consider your equal. The one whose appearance I'm borrowing right now."

"Kuh. You'd just ignore me if I told you that you've misunderstood me completely, wouldn't you…? But there's nothing that can be done," Kururu grinned. "You're just a mindless program after all, whose reactions might emulate a living being's, but are in fact just illusions, attitudes drawn directly from your core programming. After all, isn't everything you're doing right now an attempt to continue your meaningless 'invasion' that would just result in your own self disappearing?"

"Perhaps. However, my single minded objective allows me to be a more efficient invader than any real Keronian could ever be." The fake Saburo smiled while passing his hands through Kururu's hair, prompting her to slide her chair slightly backwards, gaining some distance from the apparition. "Like I had been saying, Kururu, alongside those bonds, you've earned something else. Weakness."

The mimicry Saburo spread his arms, and a translucent black globe appeared between his hands, emerging out of nothingness. "Remember your weakness! Think about how many times you've needed someone else's help in these last few years. Remember how pathetic you've been during so many missions!" The shadow laughed a bit, before continuing. "Just look at your current body! You could put the blame of your failures on your leader or even on a lack of interest from your part, but you know very well that you're slowly becoming just as bad as the others."

Mutsumi's eyes shined with a red light as he slowly became translucent, revealing a Kiru-Y floating in the air, mimicking every one of his moves. "Let yourself be enhanced by me, Kururu. You could become your old self again. No, you could surpass your old self and anyone else by orders of magnitude!"

The image solidified again, hiding the artificial keronian. "Wouldn't a universal revolution be something wonderful for your old self? Wouldn't spreading chaos for the whole cosmos bring joy without equal? To see the end of these old boring days and create a new age… Wouldn't that be wonderful?"

"Kuh. You're boring." Kururu sighed, turning back towards the floating monitor and the control panel that were behind her and quickly activating a key without hesitation. "I press."

Immediately afterwards, the Saburo and Kiru-Y vanished, it was like they never were really there. Kururu leaned on her chair tiredly, sweating. "Idiot…" She thought, "Had you not appeared here, I might have actually let you continue to stay active. Ku, ku, ku…"

Kururu turned the chair again to look at the place the Kiru-Y had been occupying and smiled. "Sorry, but it seems you're too dangerous to continue operating."

"Is that so…?"

A familiar voice hit Kururu's ears, one that she knew better than anyone else. Her own keronian voice. She immediately got up from the chair and looked at it, just to see what a yellow keronian with huge glasses standing in the previously empty room.

The keronian raised a hand, leaving it right beside his mouth and started laughing with a familiar voice. "Ku, ku, ku…"

"Huh…?!" She looked perplexedly at the image, her glasses almost falling from her face for once, dropping just enough to reveal surprised red eyes behind them.

"Ku, ku, ku…" The Kururu apparition laughed, mimicking Kururu's old voice perfectly. "Too bad, little girl, I've already won."

Next to a large building, there were many girls standing in line, waiting for their chance to get to a small entrance. Some pamphlets forgotten on the streets revealed that a live presentation of the local radio show star, the mysterious 623, was going to take place there.

Natsumi stood in that line, staring at the girls in front of her. She meant to go there with Yayoi, Satsuki and Koyuki, but ended up going alone after what happened earlier. Unknown to her, a shadow was atop the nearby building, observing her for a few minutes before vanishing.

Below, the redhead was just staring at the line, which didn't seem to move at all ever since she had arrived there.

"Why is no one moving?!" Unknown to the frustrated teen, her "Y" mark slowly started replicating itself, similar marks appearing in several other annoyed girls that were standing in that line.

/

Keroro and the other had returned to the Hinata residence, and were in the living room, Fuyuki sitting between Momoka and Alisa on a sofa while Keroro sit alongside Mois in the other one. There wasn't any visible tension, but the Sergeant was still nervous. The Y marks still were on everyone's faces and they all seemed apprehensive. No one had said anything in the way home and the uncomfortable silence still continued at that moment.

"Eh, come on! Let's try to lighten up a little guys!" Keroro stood up trying to force a smile again and got a tv remote from the table in front of her.

"I want my uncle back…" Mois murmured. She stood up, looking at the floor, and her human disguise disappeared without any kind of motion, replacing the tanned blond with a pale silver haired girl in royal clothes. The Y on her forehead was shinning strongly.

"Gero?!" Keroro backed away from Angol Mois, looking at her fearfully. Her eyes, rather than their usual innocence or even the previous anger, now seemed to be just empty.

"Lucifer Spear." The planet destructor spoke lowly in a cold tone as the golden weapon appeared in her right hand. Everyone got up when they noticed just how bad the situation was.

"Hey, Mois, calm down!" Fuyuki got up, trying to stop the imminent fighting, but he was just ignored as the Angol clan princess swung her weapon right towards Keroro, hitting her with the large golden rock at the tip of the weapon. The green haired girl yelled in pain as she flew through the air and hit a wall, falling to the floor afterwards.

Keroro held her left shoulder and just quivered as Mois approached her. "La-lady Mois…?!"

"Stop it!" Fuyuki suddenly stood in the way of the silver haired girl, standing up in front of the Sergeant. "You aren't like this, Mois! You've just been manipulated by Kiruru!"

"Why are you protecting that girl?" The Angol asked. "She stole uncle from everyone. Aren't you uncle's friend?"

"That is the Sergeant, Mois! Can't you see that?!" Fuyuki protested trying to approach her.

"Silence!" The planet destructor swung her weapon again, hitting Fuyuki's chest and sending him flying right next to the stairs.

"Hey! I don't care about the girl, but don't even think about touching Fuyuki!" Momoka raised her cannon arm, pointing it at Mois. Alisa didn't say anything, but the black snakes sprouting around her hair as she glared at Mois showed her intentions clearly.

In a small well lit room, Saburo, dressed in a black leather jacket and orange pants, was sitting comfortably, his eyes closed. His legs rested on a desk while he whistled looking at the ceiling.

The entire world was gray somehow. Everything seemed lifeless, uninteresting, boring, like a painting that had to be observed every day without showing any new facets. Of course, he had already figured it out that his current state must have been caused by a Kiruru from the last day, even before Kururu sent an e-mail actually explaining the entire situation, but there was nothing he could do to fix everything as it was. A small paper sheet slowed glided in front of his eyes, finally giving him a reason to smile.

The gray door of that room, which was supposed to be locked, slowly opened without any fanfare. No noise of broken knob or lock, it just moved to reveal an empty corridor behind it. Saburo got up, looking at it amusedly.

Stealth abilities with an offensive intent? It had never happened before, but it was expected that it had to someday. "Oh, well, at least, you brought some life to this boring day."

He pointed at the corridor, and, from a table close to him, a paper sheet suddenly rocked towards that target. When it passed through the door, a cut was left behind, revealing a brown material floating in the air, it almost looked like he had cut reality itself, but the illusion faded when the entire image suddenly moved. Some kind of transparent cloth was thrown on the floor while a blur rushed towards Saburo. However, before it could get to him, several sheets appeared out of nowhere, blocking a knife.

The figure finally stopped, it was Koyuki, dressed in her ninja garb, blue mask around her eyes included. "You're… 623?!" The ninja girl asked perplexedly, while Saburo just kept up an arrogant smirk.

"Yes, that's it."

"You've been toying with Natsumi this entire time!" Koyuki jumped backwards, moving her hands in a quick circle just to reveal that she could hold 3 small blades with each one. She glared at Mutsumi and threw the kunais.

"I wouldn't describe it like that…" The paper sheets floating in front of Saburo projected a octagonal shaped drawing onto the air that seemed to block her projectiles without problems, just frustrating the girl.

"Let's see if you can block this… Koyuki Ninpou… Blizzard spike!" The black haired placed both hands together and made a few finger gestures, afterwards pulling more blades out of nowhere and throwing them towards him. However, the second bath easily ripped through Saburo's shields, flying through them and passing through Saburo just close enough to cut his black jacket's shoulder, revealing a white shirt underneath.

Koyuki quickly used the window of distraction and ran to him, kicking his head before he could even react. Saburo grunted in pain and took a few steps back, but continued standing, and smiling.

"You're a weakling, a liar and a coward." Koyuki slowly walked towards Saburo, who just remained still.

A ring tone started playing, coming from Saburo's jacket. "I suppose you won't let me talk right now, eh?"

"Take this seriously!" The ninja leaped towards him again, but her movement was suddenly stopped as even more paper sheets suddenly appeared around her, trapping her into another orange barrier. "I can break this again!"

"I know, Koyuki." Mutsumi smirked, grabbing a piece of paper from a large pocket in his pants. "Well, I intended to play more alongside a cutie like you, but… I have this phone call now, sorry, Koyuki."

"Stop!" She broke through the barrier with her ice blades again, but Saburo just continued smiling and threw 2 paper sheets toward her. They flew through the air much quicker than expected from pieces of paper, almost matching the speed of Koyuki's own blades.

"A ninja for a ninja, isn't that fair?" Saburo grinned. "I've been wanting to see how these will fare in real combat…Keron Ride!" The two sheets exploded, and suddenly other voices started echoing in that room.

"Dororo!" The familiar voice announced itself. From one of the papers emerged a perfect copy of Dororo's old keronian body. The blue keronian, with a gray ninja back and loose cloth covering his head, drew a small knife, pointing it at Koyuki without saying anything.

"Rirara!" An energetic girly voice announced itself. It was a young yellow keronian, sporting white face and tadpole tail, her face showing an uncharacteristic smile for someone who was about to enter in combat. Her symbol was a red crescent moon, and the ears of her hat were tied by a metallic sphere into a fake ponytail. She held a large shuriken in her right hand by a small line.

"What?!" Koyuki stared perplexed at Saburo's curious constructs, but she quickly readied herself for combat as the two fake keronians jumped towards her. She readied two small knives and parried their weapons, trying to counterattack right afterwards, but had no time, as they continued their offensive.

Mutsumi took a glimpse at the number in his cellphone before quickly receiving the call. "Kururu?"

"Kuh. The Kirurus are united by a central core, if-"

Saburo just stared at the silent phone afterwards. The call had been cut somehow, but Kururu got through the essential part of the message. Kirurus were out of control, and the core, probably located in that tower, needs to be destroyed.

"Now… how will I get her cooperation?" Mutsumi looked at Koyuki, whose arms had been grabbed by the two fake keronians while she stared angrily at him, her Y mark shinning strongly.

"See, Koyuki… Don't you think that there's something weird about this?" Saburo asked while he opened his torn jacket and threw it at the desk. "Why are you even trying to kill me today?"

"Because Natsumi cares about you!"

"And… you'll kill me for that? Just… listen to yourself. Can't you see that there's something wrong going on with you right now?"

Koyuki looked in surprised for a second, just letting herself fall to the floor afterwards, looking sadly at the floor. "What have I been doing…?"

"Everyone who has that Y mark is being influenced by Kiruru." Saburo said as he opened a nearby closet, seemingly not even paying attention to Koyuki anymore. "Even myself… and Natsumi out there too…"

/

Paul Moriyama was on the ground, standing amidst rocks, sand and the ruins of a wall. If you looked at the Nishizawa mansion from afar, the destruction wouldn't seem so big, most of it was intact, save for a small section next to the leftmost corner of the building, but that was easily more than enough to create a large ruined battleground.

"Paul, that's it?" Tamama looked somewhat disappointed, holding a sphere of black energy on her hand while standing before the hurt butler. His shirt had been ripped to shreds, leaving him only with torn pants, revealing scratches all over his body while Tamama's clothes remained mostly intact, just somewhat dirty.

"I suppose this Pekoponian body isn't too bad," Tamama continued, admiring her own fingers. Her calm face suddenly changed into a maniacal expression as she glared at the old butler "I have longer limbs now for one. If only this stupid mouth weren't so small… Anyway, this is the end, Paul!" She raised the hand that held the energy ball, but stopped after the old man started to get up, realizing something. "Wait… don't tell me you haven't really given your all!?"

Paul smiled in spite of his tired and sweaty face. "There's no way I'd damage one of Momoka's precious treasures…"

"Treasure?" Tamama's glare disappeared, and she curiously looked at Paul, who slowly got up, apparently still ready for another round.

"You, master Tamama," Paul continued, pointing at the girl standing before him. "Momoka's precious friend."

"Paul…" Just as she heard those words in surprise, the darkness held by her hand extinguished itself. Right afterwards, the Y on her fore head started shinning strongly.

/

"Kururu?! Kururu?!" Keroro yelled repeatedly, but got no answer from the Sergeant Major, only static. In front of her, the situation was just as bad as before.

The living room's exist to the backyard had been completely smashed open, Alisa and Momoka lied unconscious on the grass while Angol Mois slowly walked towards the boy and girl standing inside in the house.

"You stole my uncle." Mois accused the green haired girl, while pointing the tip of the Lucifer Spear at her. "Hellmageddon… power reduced one million times!" Even though it didn't approach even one percent of Mois' full power, the Lucifer Spear emitted a beam of yellow light that quickly crossed the living room, going towards the frightened Keroro, however, before it could hit her, Fuyuki jumped on its path.

The yellow beam of energy spiraled on him, pushing him through the room before dissipating.

"Lo-Lord Fuyuki!?" Keroro looked behind her, at the boy fallen on the floor. What… What do you think you're doing Lady Mois?!" She ran towards silver haired girl, but was slapped away with a simple swing of her weapon.

"You aren't uncle! Stop talking like him! Stop replacing him!" Mois accused the girl lying on the floor, trying to stand up. Momoka and Alisa had gotten up again too, the later without any visible signs of wounds.

"I'll kill you!" Momoka yelled, aiming her arm cannon at the planet destructor. Rays of light started converging towards it as the weapon charged up, while smoke flew everywhere around the blue haired girl, coming from the scratches around her armor.

"Daddy!" Alisa commanded as the black mass on her head moved to her arms, creating giant claws that covered her hands.

"Mois, stop it! The one… The one who isn't acting like usual here isn't the Sergeant!" Fuyuki said, slowly standing up by holding onto a couch. "Kiruru is controlling you, not the Sergeant, you, and everyone here! Stop this!"

"You're lying! You want uncle to stay like that!"

"Wrong! I just want to see the Sergeant to be happy and alive! Haven't we all helped each other in the past?! Aren't we all friends?!" The Y mark on Fuyuki's shinned brightly at that point, disappearing right afterwards.

"Kiruru's mark…?!" Keroro gasped.

Mois' eyes seemed to tremble for a moment, but "Shut up, fake uncle!" Mois spun her weapon over herself, before declaring "Hellmageddon… One percent!".

Momoka and Alisa looked at each other and nodded quickly flying towards Mois. As they did so, the Y marks on their foreheads lighted up before vanishing completely.

Keroro stood in front of Fuyuki, bracing herself for the impact while sweating. She knew that if Mois went through with that no one there would survive.

"Hey, Fuyuki…" The green haired girl smiled truthfully for once in that day, looking at the boy behind her.

"Sergeant?"

"Thank you."

Angol Mois brought the weapon down, hitting the floor and smashing it to pieces as well as initiating a huge wave of yellow energy that just kept expanding itself, until it covered the entire room.

When the flash disappeared, everyone just looked stunned at the scene. Besides Mois' initial floor smash, there had been no damage at all. "Gero?"

"How pathetic, Keroro… no, leader!" The Y on her forehead burned itself at that moment. She came walking from the first floor, holding what looked like a small plastic ball on her hands. Several white buttons were all spread around its surface, a black antenna with a small red sphere on its tip sticking out. "Isn't this the weapon of the leader of the invasion forces? Take it!" She threw the weapon to Keroro, who hastily got it.

"Keroball? Well, then, I'll just have to destroy this half of the planet!" Mois concluded, pressing a finger against her own cheek while drawing an uncharacteristic smirk.

"You said that I'm not Sergeant Keroro, Lady Mois…" Keroro said, calmly inspecting the Keroball. "I think I've arrived at a different conclusion… Kiruru." She pointed the ball accursedly at the silver haired girl, who showed a moment of hesitation.

"Keroball, fire!" The green haired girl pressed a button on the ball which liberated a ray of white light that enveloped Mois, whose body fell to the ground, unconscious, right afterwards.

However, where she had been standing previously, there was a white Keronian floating, glaring at Keroro with angry red eyes.

"Kiru-Y! I, Sergeant Keroro, bearer of the Keron Star, leader of the Keroro platoon and of the keronian invasion force on Pekopon, order the termination of your operation immediately!" The Sergeant proudly proclaimed, raising the Keron star towards the artificial Keronian.

"Fortunately, I've already corrected the imperfection called loyalty." The Kiruru smirked. Unlike the other ones, that one seemed to move its mouth as it spoke. "I don't need this girl's body anymore, her entire data has been collected and my evolution to an invincible body has started. Obey the Keron Star? Soon, the whole universe will bow before my emblem!"

"Shut up!" Momoka, controlled by her inner self, yelled, finally firing her shot right into the android, which blew up with the impact.

She blinked. "Is this it?" Almost like an answer to Nishizawa's question, the noise of an explosion outside broke their brief peace.

"What was that? Kiruru again?!" Fuyuki wondered.

"It's probably the first phase of Kiru-Y's invasion." Keroro explained. "Turn on the tv."

Fuyuki got a remote control that was on the floor and turned on the tv, switching through channels quickly to a news one. Everyone gathered around the screen as images of seemingly random riots in various parts of the world were transmitted.

"What is this?" Momoka asked, trembling when the image cut away to reveal an entire city in flames.

"The first phase of Kiru-Y's invasion is meant to make the target destroy itself, manipulating their emotions. In fact, it was originally meant to be the only phase of the Kiru-Y's attack. However, this is actually just the beginning."

Almost on cue, Fuyuki's cell phone rang just as Keroro finished her explanation. "Hello? Saburo…?" The boy silently heard Mutsumi's words, thanking afterwards as he closed his phone.

"What's it, Lord Fuyuki? Lady Mama?" Keroro asked. Who would call at a time like that?

"It was Saburo, according to what he said, there's a main Kiruru unit back in that tower. If it's destroyed, the other units should stop."

"Then, it's decided!" The green haired girl exclaimed tapping the keroball. "Lord Fuyuki, Lady Momoka, Lady Alisa, stay here. I'll return to that tower alongside Corporal Giroro. We'll find Sergeant Major Kururu and hopefully stop Kiruru." Keroro said, cautiously inspecting the Keroball. Getting the wrong button at that point would be really dangerous.

An explosion abruptly shook the entire house. "An intruder?" Giroro wondered, raising a gray rifle as she glared at the living room's entrance.

"It came from here." Alisa said, pointing at the corridor that leaded to the house's main entrance, her hands still covered by dark claws. The door itself probably had been blown up, smoke was covering the whole area where it was supposed to be.

A silhouette emerged running through the smoke, but Alisa extended her right claw, grabbing whatever it was. As it turned out, it was Tamama, back in her black jacket and oversized white shirt. "Are you one of them?" Alisa asked, apparently staring at the surprised girl, though it was just her standard face.

"Someone help me!" Tamama cried for help, but Alisa quickly put her back on the floor before any was necessary.

"No Y."

"Huh… Y?" Tamama looked curiously at the dark hunter for a second, but then just ran to Keroro. "What is happening, Sergeant?! Everyone was crazy when I was returning here!"

"Private Tamama!" The green haired girl smiled when he saw the youngest member of the platoon there. "Kiruru is the one behind this. We're going to fix this situation right now!"

"Alright!" Tamama exclaimed confidently. She then looked at Momoka, who was standing there, next to Fuyuki.

"Thanks, Momochi!"

"What happened, Tama?"

"Nothing! Don't worry about it!" Tamama smiled. Momoka really thought of her as a friend, even now. Somehow, it was comforting to know that.

"I can't contact Kururu, so we're going directly to Kiruru's tower, using the Keroball." Keroro continued, while Giroro silently nodded. "Keroro platoon, let's go!"

"Were you planning to leave me behind… Keroro…?" Dororo had been standing, upside down, on the ceiling, somehow ignored by everyone. She was in her ninja garb too, and the Y on her forehead had disappeared. She hadn't retreated fully to her "trauma" mode, but her hands were clearly shacking and tears almost falling from her eyes. She swiftly dropped down, looking kind of desolated. "And I had to fight off a Kiruru by myself too…"

"Gero… I'm sorry, Lance Corporal Dororo…" Keroro scratched the back of her head nervously. Seriously, she didn't mean to hurt Dororo at a time like that.

Dororo suddenly recovered herself, staring intently at the embarrassed green haired girl. The blue haired ninja continued focusing her eyes in Keroro's direction while she place put both hands together in front of her, raising her thumbs to make a small signal. Afterwards, she raised her right arm, and a shinning disc appeared over her, one which quickly expanded and took a more specific shape – a large energy shuriken.

"Wait… are you angry now?! It's not time for this Dororo!" She took a few step backwards, losing her previous composure.

"Dororo Ninpou, 9-Star shuriken!" The blue haired girl yelled as she threw the shuriken towards her leader. As it flew through the room, several sparks could be seen around it, and it came to an abrupt stop right in front of Keroro, when the shuriken suddenly broke into small fragments and vanished completely.

Everyone in the room suddenly understood what was going on when several damaged Kirurus materialized in the room. "The house should be secure for a while. However, this won't last."

"Lance Corporal Dororo is right!" Keroro exclaimed, "Lord Fuyuki, Lady Momoka, Lady Alisa, take Lady Mois and hide in our headquarters. We're going to face Kiruru." Keroro said, her confident face already returned.

"Sergeant! You can't just go alone!" Fuyuki finally understood what Keroro meant. They would be going there by themselves. "No, it just won't work! We went together the last time and even so we were caught by Kiruru!"

"Momochi, thank you for everything!" Tamama winked.

"Tell Natsumi she shouldn't worry about anything this time." Giroro affirmed.

"We'll return soon, Lord Fuyuki." Keroro pressed a button on top of the Keroball and saluted alongside the other 3 platoon members. Soon afterwards, they all vanished in a flash of light.

"Sergeant…" Fuyuki looked at the empty space left behind by them. No, he couldn't just let them go like that.

Notes:

This chapter was the first one written after the title change of this fanfiction to "KeroGirls". It's a silly title, but it's less generic than "Keroro G", which was way too close to "Keroro Gunsou", and it also follows the pattern of Keroro's actual spin-offs (like Musha Kero and KeroZero).

I took longer to post this update, but hopefully this won't happen again. One of the main problems was chapter length, but I also went through some busy weeks. The next chapter is almost ready too by now…
