( Yuuki's POV )
When the sun rose, and we had the best visibility of the enemy, we began our attack, our ships and Gears fired at the enemy without rest, the three-meter BETAs were annihilated without difficulty, and when they were losing units at a constant pace, they showed some strategy.
A line of the taller creatures came to the front and absorbed all of our attacks without much difficulty, Those creatures were like worms, not long compared to their height, they had multiple short and thick legs, also a strong shell on their front but their back were bare, It was as if its only purpose was to be a walking shield and perhaps crush the enemy under its weight.
We could flank the army, but there is a chance they will rush our station when we split our forces, that's what they did to Tatenashi.
Yuuki: Matsu the new Glintstone weapons were installed in the Frame Gears?
Matsu: That's right, do you think it's time for a second test?
Yuuki: It is, the new durability should be enough.
Matsu: Understood~
Matsu gave the orders, and the first to shoot was Joyce, her modified sniper rifle fired a crystal bullet, and an energy trail followed it as it flew, and when the enemy was hit, the bullet passed through its entire body smoothly, leaving a perfect hole.
The rest of the girls fired with their Glintstone guns, and after a few minutes of shooting, the guns overheated, but unlike when I tested them, these could be fired again when they cooled down.
The automatic fleet resumed its attack, but at that moment, we received an alert.
Matsu: Large energy signal detected! Activating all barriers.
Matsu acted quickly, and a wall of energy formed by multiple hexagons appeared in front of our fleet, and seconds later, some energy lasers hit our barrier.
From our previous encounters, I thought they weren't capable of long-range attacks, but it seems I was wrong.
Matsu: detecting another energy signal, coming behind enemy lines.
Yuuki: Momo, Laura, circle the enemy and destroy the gunners, Matsu sends two Hybrid Gears with each one.
Laura: [ Understood, initiating pincer maneuver. ]
Those two were the best equipped to avoid the lasers, with their barrier AIC and shield drones, and with their units now running on our new triple core, their performance was far superior to before.
When those lasers were fired again, they were both targeted, I guess the enemy's priority was to protect their artillery.
As I thought, those two were able to stop their attacks, and from their IS cameras, we received images of those responsible for the lasers, that was a three-meter bipedal creature with a pair of enormous black eyes from which they were firing their lasers.
It was easy to see that they had no close combat capabilities, so the girls had no problem taking them out, with them out of the way, we continued sweeping away the BETA creatures.
Chifuyu: It seems that this is not the first time you have done something like this, how did that happen?
The battle was practically won and as Chifuyu could see that, she decided to fish for answers now, and I decided to answer without taking my eyes off the screens showing the battle.
Yuuki: Well this somehow became my job, remember the first time we talked, I told you that we had arrived at the academy by accident by crossing a portal, the portal opening was an accident but us crossing it was not, that kind of portal can be opened naturally or artificially, the reason it is impossible to find information about the Babylon kingdom is because it exists in a different world, there are countless different worlds, some dangerous, others not so much, our job is to explore these worlds and make sure that nothing too dangerous can enter or leave.
Chifuyu: It shouldn't be someone else's responsibility to do that, you're too young for something as big as that.
Yuuki: I don't think there's a minimum age for this kind of thing, Sensei, we do it because we have the power to do it, and we are not doing this alone, we have allies in some of the worlds we have visited.
By the time I had finished talking to Chifuyu, the battle against the BETAs was over, and our forces were returning to the base, then I snapped my fingers and opened a portal back to my room in the dorms.
Yuuki: Well, now that I've answered your questions, I think it's time for you all to head back.
Chifuyu: I don't think so, I'm nowhere near satisfied.
Yuuki: You're very stubborn, sensei.
Chifuyu: I don't want to hear that from you.
Yuuki: Time does not pass in the same way between worlds, when you cross the portal, we will appear behind you no matter how much time passes on this side.
Chifuyu: That's one less worry off my shoulders, that means I can stay here without neglecting my other students.
Yuuki: Sensei, I don't want to offend, but just as we have allies, we also have enemies, and they are dangerous, an IS is not an invincible weapon against these people.
Chifuyu: You're underestimating me, if my students can handle themselves here, I can do the same, It doesn't matter if this is another world, you are still my student and my responsibility, I will not return if you don't come with me.
Chifuyu looked at me with determination in her eyes, and I knew right away that she wasn't going to back down on this, then her fellow teacher, who had been somewhat confused and lost before, put on a confident smile.
Maya: What Chifuyu is saying is that she's worried about you, Yuuki-kun, we both are.
Chifuyu: ...You're saying too much.
Maya: You are not honest, Chifuyu~ we always knew that you were special Yuuki-kun, and although this situation goes beyond our imagination, that does not change our duty, Just as we can't stop you, you can't stop us either, we will support our students.
Yuuki: wow Sensei, you sounded like a real teacher.
Maya: Hey, what's that supposed to mean?
Tatenashi: Don't forget me, we are partners, Yuuki, and I'm going to take this as another mission together.
I looked behind me at Kanzashi, who was holding my shirt tightly, it seemed like no one was returning to the academy today.
