I was feeling very emotional about the dedicated plane that was finally finished, but I remembered that I didn't have time for that.
　Flying through the air, I opened the cockpit hatch and sat down on the seat, which smelled brand new, and closed the hatch. I set my phone on the console in front of me.
　There's a low start-up sound, and the various instruments on the Regingrave wake up. A monitor with a fairly wide field of view, though not all the way around, showed a view of the outside.
　When I grabbed the control stick and channeled my magic power, Regingrave moved its head as I wanted, and my vision changed. My thought tuning control is working fine, too.
　It's hard to compete with an advanced species in the flesh. But if you have a Reginrave (this guy)....

I'm going to have to do it. First of all........activate the Flying Manipulator [Fragarach]!
Fragarach is now online.

　With a voice from the phone, the wings on Regingrave's folded back opened, and the feather-like crystal plates that were lined up in a zigzag line came off. A total of twelve long crystal plates on the left and right side float around the fuselage.

It's the "Mode Change [Mode Change], Sphere [Sphere]
Fragarach is moving into sphere mode.

　What had been a long plate instantly changed into a sphere and became a crystal ball and began to rotate around Regingrave like a satellite. The [Modeling] magic is also [Programmed] for this. In short, it's the same as the Brunhild I have.
　........Okay, no problem. It's okay.

YIKES!

　Like bullets, twelve crystal balls flew into the advanced mutant. The advanced mutant slashed at the multiple tentacles in the form of swords, but the crystal spheres easily crushed the tentacles and exploded into a dark golden body.
　Each of the spherical Flying Sword Fragarach was more than a meter in diameter. In addition, it also had a [Gravity] effect attached to it. As expected, it's not as powerful as the drill rounds from the "Breunach", but that tentacle could pierce through.
　Like a sandbag being struck by a boxer, the oddly shaped mutant that floats in the air is devastated by twelve crystal balls. The body dented and began to warp like a car that had been in an accident.

''Form Change [Mode Change], Crystal Sword [Blade]!
Fragarach is switching to blade mode.

　The crystal ball changed into the shape of a sword in the blink of an eye. The crystal swords flew around in all directions, chopping up tentacles and tentacles arms.
　As it was, he ran out of half a dozen swords on the advanced species, but they didn't seem to reach the nucleus. It's tricky because when you become a mutant species, you lose your invisibility, so you can't see the nucleus.

''Then!''

　Calling back all the flying swords, Fragarach, he returns them to their original plate-like form and floats them in a circle around his right arm.

Shape Change, Assaulting Spear, Lance.

　The twelve crystal plates overlapped on his arms one after another, eventually forming a large crystal assault spear, the Lance.
　As it was, the Regingrave flew up into the air and flew towards the advanced species. Unlike Linze's Helmvige, this plane has the ability to fly even without transforming. It is possible to fly freely as if handling [Fly].

''[Axel]!

　Furthermore, he used his acceleration magic to create an explosive rush at once, and the assault spear 《Lance》 struck a blow at the advanced species. The bullet-like Regingrave's thrusting power didn't fade, and it thrust forward while crushing the golden advanced species, opening a huge windfall. The cracked body crumbled with a rattle.
　Within the crumbling part, the golden fragments, he found a bare, murky, blood-like core.

''Shape Change [Mode Change], Crystal Sword [Blade]!

　The assault spear 《lance》 instantly transformed back into twelve swords and pierced the three-meter-diameter core one after the other like a guided missile.
　A large crack appeared and the core shattered to pieces. In the next moment, the pieces of the advanced metal-like species that had been smashed into pieces melted into a sludgy liquid form.
　I watched the golden metallic fluid spreading across the desert from above as I monitored it.
　It's even better than I expected. It can move like a limb.

It's brilliant. What do you think, Regingrave?
Not bad. I like it.
''That's superposition. It's because I put a lot of things that I learned from the other specialized machines, the Valkyria. It's also equipped with functions that would surprise you, Fuyao-kun.
You're not wearing a self-destruct mechanism, just to be sure, are you?
'I thought about putting it on, but I decided not to. It's such a waste of all the work I put into it.

　Hey, you don't give a shit about me as a passenger. I'm not going to blow myself up for a mission or anything like that.
　Well, whatever. Advanced species are taken care of. Now we just need to clean up the rest of them.
　I'll put up a display of the remaining enemies on the edge of the monitor. There's a lot of them to the north and east. The sisters are, um.......heading east? Then I'll take care of the ones to the north.
　The Flying Manipulator Sword 《Fragarach》 changes into a crystal plate shape, docking one after another into the part of its back that also serves as a stabilizer, and returns to its original winged state.

Youmina and the others will take care of the remaining mutants. I'll go take care of the group to the north.
"Okay. Please be careful.
Yeah.

　After replying to Yumina and the others with Regingrave's thumbs up, they flew through the sky to the group gathered in the north of the desert in one fell swoop.
　On the northern side, the knights of the Leinie Kingdom and the Paloof Kingdom were battling with Frayes and the others.
　Compared to the knights of the Paloof Kingdom, the knights of the Leinie Kingdom were still a day ahead of the knights of the Paloof Kingdom. I'm sure you'll be able to find a great deal more to say about it.
　Below me, I could see a praying mantis-like intermediate species trying to fire lasers from the tips of both scythes at Paloof's fallen frame gear.

''State Change [Mode Change] and Reflector [Reflector]!

　The twelve crystal plates detached from the Regingrave flew in front of the frame gear that the knight of Paloof rode on, and they aligned and assembled into a large wall.
　The lasers shot out from the intermediate species hit the wall and were reflected at my arbitrary angle and disappeared into the sky. If the other party wasn't Fraise, it would be reflected back into the main body.
　I cut the mantis medium-sized species that fired the laser into pieces from behind with the crystal sword in my hand. Without aiming, he also cut the nucleus in half, and with a rattle, the intermediate species crumbled into the desert.

''State Change [Mode Change], Dagger [Dagger].

　Once again, the crystal plate, which was once a wall, was divided into twelve parts, and one crystal plate was further divided into four parts. Each one of them now transformed into the shape of a dagger. The twelve plates were transformed into forty-eight daggers.
　The forty-eight crystal daggers radiated around Regingrave. ''Alright, let's go!

"Meteor Shower, Gladius.

　Forty-eight meteors flew through the air, drawing trajectories in all directions, piercing the nucleus of the nearby flames one after another. The swords glittered brilliantly like a meteor shower as they pierced and searched for their next prey.
　An all-directional and simultaneous attack by the majority of flying swords "Fragarach". This is the Meteor Shower [Gladius].
　This is the reason why the Flying Sword Fragarach is able to control all of the swords by itself. Although there was some system support, the normal limit was four to six swords. Any more than that and the accuracy would be lacking, and at worst, the swords could collide with each other.
　However, Regingrave is also using 【Accel】's thought acceleration. With this, it is possible to control forty-eight swords at the same time towards a target.
　Of course, if you're not careful, you can miss them. At first I was going to use the target lock on my phone, but that would make it impossible to use it flexibly, such as when changing course for a single sword or making a feint attack.
　So it's a lot of work, but honestly, I don't think I needed 48 of them. Besides, I tend to neglect the operation of the main unit when I'm using it. Well, you can reduce the number depending on the situation.
　The lower-grade types have just one sword, while the middle-grade types have multiple swords that combine to form a long sword that pierces the core.
　Meteors flew across the battlefield in every direction, and before I knew it, I had defeated all of the nearby flames, which were about five hundred in number.
　All of the 'star swords' return around me and begin spinning like satellites again.

''Fuu........''

　Whoa, whoa, whoa, whoa!　While listening to the cheers of triumph that emanated from the knights around me, I let out a breath of relief as I was held in the sheet.
　It's pretty tough, this........
　But this is not the end yet. The battle is still going on. Now I have to go support another part of the city, and just when I thought that I'd have to............................... And then I heard something close. What is it?　As I wondered, the light of the Regingrave's instruments in front of me gradually became weaker and weaker.
　With a cooing.....With a toned down sound, Regingrave began to descend. The 'Star Sword' returns to its original crystal plate and is stowed away on its back.

''What the hell!　What's going on!''
''Don't panic. It's gone beyond its operational limits.
Are we running low?

　I couldn't help but respond to the doctor's voice coming from my phone in a strange voice. What's the operating limit, I've never heard of it before!
　I get down on one knee in the desert and manually open the hatch to get out of the stuck Regingrave. A puffy desert heat entered the cockpit.

'Unlike other aircraft, the Regingrave is operating by directly absorbing your magic power. However, the Regingrave still can't withstand the amount of magic you're putting into it. It's designed to force you to stop before you become like Dverg. Well, this is where there's room for improvement.''
Well.....

　It's only running about enough. No, it's a hell of a lot better than blowing up the engines like the Dverg. I can't laugh at myself as a self-destruct mechanism.
　If I save my magic power and make it work, will it last a certain amount of time?
　Well, I think we can all take down the rest of the Flays, but if we had reached the operating limit before the advanced species were released, we might have been in trouble.
　I'll have to think about the timing of this aircraft. I'll save it for when the advanced species might come out!　What a thing to do, I didn't get it!　It could be something like that. Even if two of them show up, like this one, if there's a time lag in the appearance of the second one, it's going to be troublesome.
　Removing my phone from the console, I exit the cockpit and step onto Regingrave's shoulder. The sunshine is still hard as ever.

"At any rate ... good job, Regingrave. It's good to see you.

　I look at the profile of the plane that will be my partner. Oops, I'll have to turn the frame gear that Reignier and Paloof's knights are riding in, which I've been handpicked for, to another place.
　I decided to store the Regingrave in 【Storage】 for now and send everyone to the next battlefield.
