An advanced species of nautilus was floating wobbly and about four meters high above the desert. As I recall, my grandfather had told me that the nautilus floats and sinks by building up and expelling gas inside its shell. Because of their similarity to submarines, the writer Jules Verne gave this nautilus an English name for the submarine in his novel. "The Nautilus".
　They say that nautiluses are not capable of quick movements, but I wonder if that applies to this advanced species....

''What do we do......... I didn't expect two advanced species to appear. It's impossible to defeat them all together........

　As a special trump card, there's a giant demon gun called the "Breunach" that shoots out drill rounds. With that, you can take out even the most advanced species with a single shot if you're lucky.
　However, it takes a long time to fire one shot, so you can't fire continuously. Furthermore, in order to fire a second shot, you'll have to disassemble it with Babylon and adjust it to regain its crazy aim.
　In addition, firing that thing requires an enormous amount of magical power and fire and wind magic.
　I can pour the magic power into it, but if I inject the wrong amount, it could explode just like the Dverg. If it's done poorly, it could endanger Linse and Lean, who are dealing with 'Breunach'. So I dismiss that.
　On the sand, even if you apply 【Slip】, the targeted sand will be scattered by the wind immediately, so it won't be effective.......

In any case........first, take a break, Meteor Shower [Meteor Zapper]!

　Softball-sized "stars" made of shards of crystallized wood appeared one after another in the sky above the two advanced species. They were pre-applied with [Gravity] and became meteors that rained down on the ground.
　Perhaps noticing the stars flying in from the sky, the advanced species of peacock raises its head.

　''Kiiiiiiiiiiiiiii!

　With a high-pitched resonant sound, the peacock pointed its spread tail feathers to the sky. If you look closely, you can see that the round pattern of the tail feathers, as we say in a peacock, is rounded like a lens, and a small light has begun to gather there. Don't tell me that was...!
　Cubbas!　And then countless lasers that were diffused from the lens of the tail feather were released. It shot down every falling star. No, it shot down, or rather made them disappear.
　That's a diffuse particle cannon modifier!　How do you prevent something like that from happening!
　As I was getting impatient, Peacock Flames folded its tail feathers, laid them straight, and returned to its original state. It was as if it was putting away its weapon.
　What the hell?　Couldn't the other side, by any chance, release it in succession as well as "Breunak"?
　I don't know but that peacock's diffuse laser is not good!　Strike while you can!

'Monica!　I need you to beam "Blaunak" out of the "hangar" as soon as possible.　Linse, Lean, get ready to fire!

　Send instructions on your phone to Monica in the [hangar] in Babylon.
　There are still stars with [Gravity] in [Storage]. But I'm limited to one more shot in terms of quantity. If I drop it on him now, I can do some damage, but it won't be enough to kill him.
　If that's the case, I'll throw a Meteor Shower Meteor Zapper at him before firing the Breunach, and if he uses his diffuse laser, I'll use the Breunach to crush the nuke while it's charging.
　The question is, how long will this situation last until then?
　The 'Breunak' was transferred from Babylon, and Linse's Helmwige and Lean's Grimgelde caught it firmly between them.
　They each connected the cords extending from the Breunak to the connectors at their hips. The claw-like anchors on the breunach were driven into the desert.

'Breunak connection. Charging commencing.'

　At the same time as Linse's voice, the gauge on the side of the Breunach slowly extended. Looking at it with a sideways glance, I sent instructions to the other dedicated machines 《Valkyria》 and the others.

''Else, Yae, Hilda, check the Peacock Flays, divert your attention away from Linze and the others!　Lou and Yumina, pull the nautilus Fraise away from the peacock!　Sakura and Sue, you'll be guarding Linse and her friends!　Just leave the mutants alone for a while!

　It's not necessarily true that the nautiloides don't have a diffuse laser like that one, either. The Meteor Shower Meteor Zapper," which was a great deal of work, was nothing if it was shot down by that one.
　The mutants are also troublesome, but even the heavy knight Chevalier is not impossible to defeat. I'm sure you'll be able to find out more about this in the future.

''d*mn...!　You're getting in the way of my long tail!

　Else's Gerhilde was slowly approaching, dodging the folded tail feathers that were swung around whenever Peacock Frayze changed direction.
　Similarly, Yae's Schwertrite and Hilda's Sieglune also ran over the desert to Peacock Frase.
　Eventually, the three planes reached the peacock's right leg standing in the desert, and each of them fired a full-blooded blow into that leg.

''Powder, shatter!
The inner workings of Kokonoe Shinmei-ryu, Housuuhiren.
"Restia Style Kenjutsu, Three Styles, Zantetsu!

　Gerhilde's pile bunker, Schwertrite's sword, and Sieglune's sword are simultaneously released into Peacock Frayze's right leg.
　Compared to the advanced species such as crocodiles, gorillas, and rickety turtles that had appeared before, this time Peacock Frayes had thin legs. Unable to withstand three simultaneous attacks, the peacock's right leg shattered beautifully.

''Alright!''

　His legs were shattered and Peacock Flames lost his balance. All three planes quickly broke away from the spot to avoid collateral damage to the falling body.
　The impact of the advanced species' fall sent dust flying high into the desert. The shattered right leg would be regenerated soon anyway, but this would buy them some time.
　Beyond the Peacock Flays, using the multi-directional vernier of the "B 《Booster》 unit" mounted on his back, the Valtraute riding Roux's ride repeatedly moved quickly and accelerated, drawing the nautilus guy to him.
　While the nautilus floated wobbling and floating, countless tentacles were thrust out to Valtraute, like a spear. However, Valtraute, equipped with a B-Unit, quickly ducked to the right and left, retreating backwards through the desert.
　Apparently the nautilus is not so quick. Rather than flying, it's just floating, so it probably can't move fast.
　Still, you can't be too careful. Even if the body isn't quick, the speed at which it releases its tentacles is quite fast. If Valtraute hadn't been a B-Unit, he wouldn't have been able to evade it with so much time to spare.
　Suddenly, Gakkah!　With a sound of destruction, one of the nautilus tentacles shatters. It's probably sniping by Brünnhilde from Yumina at the rear.
　Brunhilde has a stealth function that allows her to blend in with her surroundings, so you can't see her from here. And when you deactivate stealth, the silver body reflects the sun, making it too glittery and conspicuous.......

''The filling is complete!　I can shoot you any time I want!

　He turned his gaze back to the peacock at the communication from Lean.
　The peacock's right leg had already almost regenerated, and it had begun to rise up on its own.
　Perhaps noticing the magical power of the 'Breunak' aiming at him, the Peacock Flames spread its wings and shot out from them in a single shot at Linze and the others in the shape of a surfboard.
　Countless crystal feathers were closing in on Linze and Lean. However, what stood in front of them was the huge frame gear that Sue rode, the Aldrinde Overlord, which had already fully merged with the support mecha.

''Stardust Shell!''

　The countless star-shaped lights emitted from the held out left hand lined up in the blink of an eye to form a defensive wall of light. All the crystal wings that flew in were protected by the star shields and were flung away.
　When it came to defense, there was no plane to the right of Aldrinde. As long as we put the youngest Su on the battlefield, we've piled safety on top of safety.
　The wings of the peacock flames that shot out their wings regenerate. If you want to do it, it's now.

''Try again, [Meteor Shower [Meteor Zapper]]!

　This time, he drops a 'star' at Peacock Flaze's single target. Reacting to this, Peacock Fraise spreads her tail feathers and takes up an intercepting stance, just as before.
　The diffuse lasers are released again, and the meteors above their heads that were about to attack are annihilated one after another, just as before.

'Now!'

　Drill rounds were fired with a roaring sound from the 'Breunak' that Linse's Helmvige and Lean's Grimgelde had set up.
　The drill rounds flew up the desert sand and pierced Peacock Frayze's chest in a straight line.
　The stinging bullet made a tremendous destructive sound in the desert and thrust forward while spinning through Peacock Fraise's body. As it was, the drill bullets pierced the large orange nucleus deep in the chest at once and went through to the back.
　Peacock Frase's movements stopped and countless cracks ran through his body. In the next moment, with a roaring sound, the Peacock Flays shattered into pieces, turning into a rattle and crystal wreckage that created a pile of rubble in its place.

''First one...!

　Bushee!　When I turned around to hear the sound of "I don't know what's going on," steam smoke was already rising from the frame gears of "Breunak" and Linse and the two others.

''Are you two okay?''
"No, I'm fine. No problem.
''This one too, somehow........ I don't have much magic anymore, but...''

　The two of them will be able to recover some of their magic power itself from the engagement ring I gave them.
　However, apart from that, there should be physical fatigue from using 'Breunak'. It takes a certain amount of energy to use magic. And you've just about used up all your magic power at once. You have to give them both some rest.
　In any case, Helmwige and Grimgelde are probably under a lot of strain too, so the battle won't be possible for a while.

''I'll transfer them both to the main camp once. You can have Flora examine them.

　In the main camp, not only Rosetta from the 'workshop' for maintenance of the aircraft, but also Flora from the 'alchemy building' is waiting in the main camp. This is to treat the knights who were injured in battle.
　I open the [Gate] and transfer the two Flame Gears to the main camp, along with [Breunak].
　Alright, now we'll take care of the nautilus........

''Fuyao-san!''

　At the sound of Yumina's voice, she turned her gaze towards the nautilus. What she saw there was a nautilus that was struggling in the air, possessed by many mutant species.
　The mutant species attached to the nautilus were invading the nautilus as if they were fusing their own bodies together.
　The nautiloid frays were squirming and reaching out with their tentacles, chopping up the attached mutants.
　But there were too many of them, anyway. Little by little they were fused together, gradually changing, like the body of a nautilus being painted with dark gold paint.
　Eventually, the nautilus dropped with a thud onto the desert and began to rampage, waving its numerous tentacles around with impunity.
　Without a doubt, the mutants are eating the nautilus frays. No, they're trying to take over.

''Fuyou-dono, take that!

　Suddenly, a number of disastrous spine-like things grew out of the nautilus shell. The thin tentacles fused together, turning into long, thick, squid-like tentacles.
　The metallic sheen and sharp angular form of the creature didn't give it the stubby and creepy look of a mollusk, but it was still creepy.
　The nautilus, whose entire body was invaded by the dark gold coloration, moves cunningly. You can't call it a nautilus anymore - - no, you can't call it a nautilus. It was a mixture of squid, octopus, snails, and other such things, which made it an odd shape.
　The whole body seems to have grown a size as well. Did it grow to the size of the mutant it was obsessed with?
　The advanced mutant's metamorphosis continued. The part of the nautilus shell cracked open to the left and right, and many long, cone-shaped things began to jut out from inside.
　Suddenly, they were shot out in all directions in a disorderly fashion, like rocket fireworks. The cones that were shot out exploded in the air and turned into even finer arrows, raining a rain of crystal on the desert.

''Shield!''

　The 【Shield】 prevents the rain of arrows falling down.
　Is this the cluster bomb modifier used by that advanced species of crocodile in Euron?
　It doesn't matter if it's an enemy or a friend. He attacked all the flames and frame gear. Maybe that guy who assimilated the mutant isn't a friend already.
　Here and there, Frase was shattered, and Frame Gear had damaged arms and legs. Frase will regenerate as long as his nukes are safe, but this one is not.

'Rosetta!　What's the damage from that attack?
Twenty-nine medium-damaged, seven badly damaged. But two of them are seriously injured. But two of them are badly wounded. We're not going to die, but combat is not possible.

　Maybe he was unlucky enough to hit the cockpit, or maybe he took several shots at once. Whatever the case, it's good that he didn't die, but.....

''Fuyou-sama!　The same one again!'
''What!?''

　I looked up at Lou's voice as he jumped in and looked at the advanced mutant, and before I knew it, the same missile as before was lancing up.
　The missile was launched again. And again, crystal arrows were scattered over a wide area. ''d*mn it!　Come on, man!
　19 medium wounds, 8 major wrecks, and it looks like there were three more serious injuries. If this happens again.....

''Fuyao-kun, can you hear me?
You're a doctor?

　We get a transmission from the doctor who is supposed to be in Babylon. What's going on?

"I haven't even broken it in yet, but that's OK with me. I'll send your aircraft to you now.
'　Are you finished?
About 90% of the way. I'm 90% sure that's all there is to it, but even so, you should be able to fight just fine.

　Particles of light gathered in the desert, and in the next moment, there was a single frame gear standing there.
　Its entire body was clad in crystal armor, with several golden lines running across its transparent parts. Its size was the same as a standard frame gear. On its back, it has what looks like folded wings, but those are equipment, not wings.
　It is equipped with wide swords at the left and right hips and no shield. Basically, it's for the purpose of mainly attacking. The two horns on the head extended backwards, and the shoulders had a sharp angle that jutted out as well.
　Overall, it has a stylish feel to it, but at the same time, it is a powerful aircraft.
　This is my own personal frame gear, the versatile Versatile Diversified Warfare Type "Regingrave".
　This frame gear, named after the "Inheritor of the Gods (Regingrave)," shimmered in the light of the sun.
