Chapter 1

It was an ordinary day. The Hinatas were doing ordinary things as usual. Natsumi and Koyuki were listening to "623 my radio", Fuyuki and Momoka were doing research for occult club's next presentation. Aki was working extra hours. There was nothing unusual happening, at least not on the surface.

Dozens of meters below, six alien invaders were having their daily invasion meeting. Five keronians sat around the table, while Angol Mois stood by with a sweet smile. On the whiteboard behind her wrote countless absurd invasion plans that had been discarded.

"Why can't we come up an adequate plan?" Keroro slumped on the chair, looking at the rotating fan on the ceiling.

Giroro gave a snort of derision. "When was the last time we had an executable plan?" After staying here for two hours, he's obviously become impatient.

"73 days ago in pekopon calendar." Kururu answered casually. He leaned back on his chair with his feet on the desk, resting leisurely.

Tamama rolled his eyes but didn't say anything. In fact he paid more attention to his Coca Cola than the meeting.

Dororo still sat straight on his seat silently.

Mois stepped up to massage Keroro's shoulders at the right time. "You could say, have no clue?" She didn't notice Tamama's jealousy in his eyes.

"Ahhhhhhhhhh!"Keroro decided to simply give up further efforts. "Enough for this meeting. Now dismiss-"

Before he finished the "s", piercing sound of sirens were everywhere. Hidden warning lights also flashed blindingly.

"Kero?! Why would a 'dismiss' trigger the alarm? Anything wrong with it?"

Kururu was uncharacteristically serious. "It's none of your business...Kukuku, too bad, strong pulse of gravitational waves detected. Space-time shockwaves are on the way. Run or die." With that he took out a button from nowhere, ignoring the confused looks of others. "Press it!" Kururu's chair transformed into a hovercraft in the blink of an eye, flying to the exit without waiting.

Other platoon members processed that information with great difficulty. "Anyway, run!" Tamama muttered "Is this a prank of Kururu-senpai?" but he still followed with no more protest.

"It's safe when we get out. The space-time structure in secret base has been stretched so it's not stable. That's why it's vulnerable to space-time shockwaves. " This is the fastest explanation for his teammates to understand, apart from Keroro.

"What? Wait- I didn't get it!" Keroro gasped. He didn't know what was happening, the only thing in his mind was running for his life.

Hyper-space portal connected to Keroro's room was right in front of them, but Kururu past it without looking at it twice. Keroro didn't think much and rushed into the portal, into "safety"...

Keroro heard a loud "Bang" and saw lights. He felt like his body was stretched along with the space, and the moment lasted for an eternity...

Consciousness came back to Keroro suddenly. He looked around but didn't see anything except darkness, nor did he heard anything. A cold feeling crawled up his spine. "Am... Am I dead? No! There are so many Gunpla models to assemble, so many manga to read, so many-"

"Shut up, you moron!" Giroro's slap effectively brought back Keroro's sanity. It turned out the surroundings are not entirely dark but dimly lighted, just bright enough to make out his five teammates. And those five were all looking at him.

Mois hugged Keroro in excitement. "Mois is so happy that Oji-sama is safe~" Keroro tried moving his limbs but found something was off. "Mois-dono... When did you turn back to your ture form? And why is everyone... floating?"

The figure looked like Kururu facepalmed. "Why does every author make me to do the explanation... Forget it. You went through the portal at the wrong time, which caused the gravitational waves to resonate. As a result, the shockwaves arrived much earlier and created a wormhole. Now we are probably thrown into another universe. Although we can survive in this universe for now, we don't even know how much the fundamental laws have changed. This is not going to end well. From what we know, at least- "

Giroro tried summoning his guns with a gesture, but nothing happened.

" -the hyper-space connection is disabled- "

Tamama gave his trademark blow a test, but failed as well.

" -and we cannot wield dark energy to use our attacks."

Dororo has already made similar attempts. "Perhaps being alive itself is a bless for us."

Keroro scratched his head. "So what are we going to do?"

"Right question!" The mysterious voice spoke abruptly, startling everyone. The unisex voice came from all directions. Since Keroro platoon still had their translator (and anti-barrier and environmental regulator) on, they didn't notice which language it's using. Everyone was on guard except for a puzzled Keroro.

"Take it easy, guests~ I have no ill intention. Your abilities may have been deprived, but it's merely an accident. And I believe such inconvience won't spoil the Game~" The unknown being spoke with a velvet tone, which only made his/her words sound more dangerous.

"Game?" Six aliens looked at each other, unaware of the meaning but automatically recalled that odd and perilous RPG game, Kishi To Musha To Tensetsu No Kaizoku. Not so good.

"Don't worry, my Game is much better than Gemumu's~ No burdensome quests, no troublesome artes. You don't need to kill mobs all the day for a level-up, because there are only a few levels to play. Elimination game, only one winner. Isn't it easy enough?"

"Is that even a game?" Tamama scorned.

The voice might have sensed their boredom, and began to lure them. "As for the prize for the winner... What about dominating the world, possessing the whole universe, and fulfilling every wish?"

The atmosphere changed suddenly, and the mysterious being took a step forward. Six crystals appeared before them, which looked like the five ones they got on Planet Sengoku. But they are more acute on the end, from 72 degree to 60 degree, and there was a pink one.

The crystals flew into their hands. Giroro scrutinized it for a while. "What's this?"

"They are your certificate in the Game. Don't lose them, or you will automatically lose."

"I have no intention to join this game. Can I give it back?" Dororo handed out the blue crystal calmly.

"Oh, it's a first time. But my answer is, NO. In my Game, you have no right to leave!"

The tone darkened sharply, and there was thundering noise everywhere. Cracks can be seen on the dim background, and light emerges there.

"No more chat. Game start!"

Before being enveloped by the light and lose consciousness, Keroro only had one thought: No, not once again...

Gravity was back. They fell on the ground. Keroro got up and dusted himself off. Everyone has got an afro as if having been in an explosion. And this dusty room is...

"This place is...this is my room! No! This is the basement of the Hinatas!"

Kururu was thoughtful. "The energy leaked from two wormholes shouldn't have been this huge..."

They went unstairs and investigated the Hinatas. 5 minutes later, they came to a conclusion.

1. This was a parallel universe where they had never come to Pekopon.

2. No one was around, and it's the same in the distance. All kinds of signals were cut off.

3. The hyper-space connection and dark energy were still disabled. Mois was merely a normal girl with strange costume.

Giroro looked at the clearing in the backyard that was his tent, holding the belt which gave him strength. "Natsumi..."

Tamama grabbed a pack of snack from living room. "Does that mean we will never meet Momochi and others?"

"Not necessarily." Kururu's glasses flashed. "If the mysterious being was telling the truth, after someone win this game and dominate the world, what cannot be achieved? Everyone, do you still have your crystal?"

"We can't believe every word it said, but now we don't have a better plan." Dororo appeared from nowhere. "There was no one out there, and invisible walls are blocking every direcion except for one."

Keroro understood. "So this game thing lacks free choice. Only one main storyline?"

"You could say, The Adventure Line?"

Keroro put away his green crystal, opened the front gate. "In that case, let's join this treasure hunt game. Keroro platoon, set off!"

In the direction they were heading, at the foot of Nishizawa Tower, a group of people appeared. A blond guy lighted a cigarette, looking at the oppositing direction, gave a snort of contempt.
