"Area 37-B, 4 Vipers, over."
"Noted, proceed with investigation, over."
"Nin!"
"Dororo-san, you are supposed to say over. You could say, following the rules? Over."

"Desu, over."

The other side of the sound only transmission device hang up. The room was once again quiet.

The two investigation team had gone out three hours ago to examine detailed information about the Viper's planet and their main base before we secretly attack. Everyone else stayed in the ship, including Giroro Senpai, who seemed to grow more and more impatient by the second. I wondered if he was worried about his nii-san or he just disliked being left out on the front line of the battlefield that much?

"And now we are connecting to Garuru Chui." Mois pressed some buttons on the main computer.
"Garuru Chui, how's the situation down there in area 12-C? Over."
"Everything's going according to plan," the voice of the other platoon's Taichou filled the room, "the condition of their base is just like Kururu expected. Tell him thanks for me."

Tororo rolled his eyes disobediently.
"Humph, old man."
"Kuku."

"We will be preparing to enter the base right away, and Pururu has already-"
He paused for a second,
"Pururu? Pururu?!"

After the sound of Pururu screaming, everyone's attention was pulled towards Mois and the conversation.
There was a loud bang, and some crashing noises, then the sound of a gun firing.
Giroro Senpai stood up from where he was sitting.

The transmission device was clearly broken.
"…ert…alert…re dis…covered…vip…ers…"
The room returned to silence as the blinking light went out.

Were we discovered? But how? Didn't they put on anti-barriers before leaving? How did they find us?
I started typing on my laptop, and so did Tororo, as the rest of the Garuru Platoon went into shock.

"Tamama Nitouhei!" Keroro Taichou realized suddenly and yelled, "what about Tamama? Are they okay?"

Mois pressed more buttons, connecting to Tamama and Dororo. Taichou was clearly worried and maybe even frightened, but there was no answer from the other side. The whole room was under the pressure of tension and dying suspense. Finally, someone picked up.

"Keronjins, hehehe," said was a low, harsh voice of a Viper, "I knew you guys would come. I've captured two of your comrades. If you want them back, surrender to us, but if you try to play any tricks, hehehe,"

There was a breaking sound, and then the noisy background of sound transmitter disappeared for the second time. He clearly crushed it.

"NO!" Taichou panicked and screamed. "We have to save them! We have to go and rescue them!"
He continued yelling as he ran towards the exit.

"No Oji-sama, you can't be so reckless!"
"Baka, calm down!"
Mois and Giroro Senpai grabbed him and tried to pull him back, but it was useless. Taichou broke free, took one of the small emergency rockets and left at top speed.

"Damn it," on the ground, Senpai said as he straightened his hat, "someone needs to go after him before he gets us into trouble, that fool."

"I'll go!" Taruru said while running towards the exit. Zoruru followed him.
"Wait, can you two-"
"Don't worry," Taruru gave Senpai a thumbs up, "now that even our Taichou's under attack, we really can't just sit around and do nothing anymore, can we?"

"Kuku," I stood up, "that kid does have a point. I'll go find Garuru Chui and Pururu Kangochou. Maybe I could gather some data on the way."
"Wait, I'm coming, too." Giroro Senpai materialized a gun and ran after me.

I hopped in one of my robots that I designed for this mission, and he climbed in behind me.
"Kukuku, Senpai's coming, too?" I twisted my neck to turn my head around.
"I can't let you go alone and get yourself killed." He said, not looking at me.
"Don't you have any confidence in me? But if you really want to come, that's fine."

I turned back to face the controller, and pressed down a few buttons for launch.
"Kuku, I forgot to tell you, if you don't want to get blown off, you better hold on tight, Senpai."
"Wha-"

Before he could finish his sentence, I sent us off flying. Giroro Senpai caught up to the situation and grabbed on to my waist, right before the humongous wind created by the incredibly fast speed attacked us.

"Kururu are you crazy?! Inventing crap that goes this fast?!"
"Ku~kukukuku"

He held on tighter and leaned closer against me so that he won't fall off. Kuku, not designing seat belts paid off.

We landed at the edge of Area 12-D, planning to walk the rest of the way.

"Kururu, why didn't you leave your laptop on the ship?"
"I told you, I need to collect data, and figure out the reason why the Vipers found your nii-san. You just focus on looking for him."
I continued typing on my laptop while walking behind the Gochou.

Senpai took out his communication device. "Mois? Yes, we've arrived. Now please tell me the location."

I blocked out their conversation as my mind started getting stuffed with thoughts.
Both Garuru and Pururu had their anti-barriers on. They are not the reckless type, so I doubt that they would do anything stupid. And judging by what we heard before their communication device broke, they were most likely under a surprise attack. Does this mean that the Vipers have some unknown ability that could see through the barrier?
No. Our invisible barrier is designed with Keron's top technology. Besides, if it was actually useless towards the Vipers, we would've been discovered a long time ago.
If the barrier was working fine, that means they found us by other ways than eye view. What was it?

"Uh, yes, that's about where we are right now. Could you go into more details, Mois? North? What? I can't hear you."

Unknown Planet 47F Vipers
I read on my laptop.
Snake like, athletically strong, most have metal/weapons built in body parts, habit on unknown planet in the radiation belt between planet 47 and 48 of the Appalaken Galaxy-

I stared up at Senpai.

"What? East? South? Speak more clearly. I keep on hearing noises. Mois? Mois?!"

This planet sits in a radiation belt, without the protection of a magnetic field, it's natural that its residents had grown used to the deadly radiation waves, and their highly accurate detection of any other form of electronic waves should also be expected; any other form of electronic waves, from radars, satellites, sound transmission devices…

"Senpai!" I yelled while running towards him, "hang that up! Now!"

He turned his head and looked at me with confusion in his eyes, but they were soon replaced by shock and fear. Senpai stared through me at something I couldn't see.

I quickly turned around, only to discover the circular shape of a gunpoint right in front of my face.
