You're not... are you the Mage King?
How true. This personification is a puppet in my place. For ten years now, I've been moving my brain to this side, freeing myself from the yoke of my body.

　I didn't expect you to have stopped being human long ago........ Behind Hecaton Cale's forehead, his brain, floating in an emerald green water solution, swayed in a small way.
　What he's doing is the same thing as Dr. Babylon. The only difference is that Dr. Babylon has an artificial life form that is a fusion of magic and machinery, and the Mage King has the Golem of the ancient plane 《Legacy》 as his body.
　Well, when you consider the level at which the body can finally be controlled with the assistance of fifty golems' brains, Dr. Babylon's technology is far superior.

''Kaka. Even someone as good as you have been taken aback?''
No, no?
Nuh-uh?

　I was surprised by the bare brainedness of it, but not so surprised by the act itself. It's a common subject for cyborgs and other sci-fi works of that nature.
　I'm sure it would be creepy to actually have it in front of me, though.

''Well. What does it matter?

　I held up Brunhild, which was loaded with 【Explosion】 granting bullets, and mercilessly pulled the pull iron 【Trigger】.
　A huge explosion occurs on Hecaton Cale's forehead. But when the explosive flames disappeared, what I saw there was the figure of a brain floating in the water solution, unharmed.

''Mu.''
"Kaka!　Do not lick Hecaton Cale!　This armor won't accept magic!

　If you look closely, you can see that Hecaton Cale's armor is crisscrossed with fine patterns. Is it a type of imprinted magic? It seems to have been thoroughly engraved in order to maximize resistance to magic.
　Considering the ancient golem battles, the target is probably not a wizard, but rather a golem with an ability. Or, old man, it's not your fault.

"Reload.

　He changed all the bullets in the magazine to normal bullets and pulled the trigger again.
　With a bang, the bullets were bounced off something before reaching Hecaton Cale and changed their trajectory.
　Wee, I knew it. They're deploying a protective wall just like my 【Shield】. It's impossible to pierce that thing with Brunhild. Probably even Yae and Hilda's swords would be pretty tough. No matter how sharp the slice is, it's impossible to handle a tuna with a razor.
　I'm wary of the area as a loud ground rumbling begins again. It's not impossible to deal with anything, but I can't help but be slow to react to the first one I see.
　Even though it's becoming divine, it doesn't mean that my thinking ability has been enhanced to the point where it's becoming divine. If I had always activated 【Accel】 at all times, the speed of thinking would have been faster, and I might not have been able to get my magic power sucked out of me in a whisper like I was doing earlier, but...
　Naturally, I want to spare you from always living at a broken speed.
　Gagoong!　And the sound of something collapsing echoed through the factory. Immediately afterwards, a chain of sounds of destruction began to roar from all over the place.
　Hecaton Cale is on the move. Are they trying to break through the factory?

''Kaka!　Let's see if we can't part with such a small place!
Hey!　We're right underneath the castle!　There are a lot of people up there...!
'So what?　Do you mind the ants when you walk?　That's weird.

　d*mn, you're a mental quitter, you old man.
　The part of his forehead where his brain was visible and the eye on the side of his head closed, and the next time he opened it, there was nothing there. Had it moved to a different part of the plane?
　No wonder. There's no way I'm going to leave that obvious weakness exposed.
　Hecaton Cale begins to move. Everything in the factory has begun to break down. It's not safe for us to stay here any longer. There's no way to know when the ceiling will collapse.

[Teleportation]!

　I embrace Yae and Hilda in my arms and transition to the capital of Isengard.
　The place we moved to is south of the castle, on the roof of the tallest building in the capital. You can see the castle clearly from here.
　The battleship's top, a top-like tower, now billows with smoke and is on the verge of sinking. Many people were fleeing from the castle.

Target acquired!　All the humans left in Castle Isengard!
Commencing capture.

　A huge explosion occurred continuously from the direction of the castle, interrupting the voices that flowed from the phone. Then, out of the flames and black smoke, huge black mechanical wings appeared.
　Explosions and sounds of destruction occurred everywhere in the collapsing castle, and now "that guy" was about to appear on the ground from underground.

".........capture is over.
"Move everyone to the plains three kilometers from the capital!　Immediately afterwards, activate [Mega Heel]!
Copy that.

　I immediately give orders to report from my phone. I don't think this would have saved everyone. It's because there's nothing I could do if I had already died or had a protection against becoming a magical target.
　As if to mock me, the castle's top tower finally tilts and disappears into the flames.
　Instead, the massive wings reappeared, and not only the castle, but the streets leading to it began to crack. Wait, wait........the body extends not only to the castle, but also to the basement of the capital!
　A black, distorted metal tail appeared from the cracked earth. Not just one. Two, then three more. The area around the castle was already obscured by flames and smoke that made it impossible to see.

''Kaka!　Delightfully delightful!　I feel great!　I've finally surpassed them in ancient civilizations!　The unfinished Hecaton Cale has been completed by this eagle!　Kaka-kaka!

　The voice of a crazy Demon King comes from within the black smoke. No, that was already crazy.
　From the basement of the castle, surrounded by flames, "that guy" finally emerged.
　His entire body is black with brass lines running down the length of his body, and he has two large horns on his head. On its face, there were what looked like eyes and what looked like a mouth that had been split wide open.
　There were four large arms from the torso, and many other medium-sized arms sprouting from various places, including the sides and chest. Two large wings extended from its back.
　If I were to compare it to a mechanical, multi-armed demon. It had a number of long tails, with a snake-like head at the end of them.
　Its tail buzzed like a whip, smashing the castle's walls to pieces. It seems to have quite a bit of power.
　But anyway, it's big........ Isn't it as big as an advanced species?
　Was something like this lying in the basement of the castle?

''Fuyu-dono, we have to stop that thing!　We're in frame gear...!
''Uh......... Regingrave is in [Storage], but the two planes are Babylon.......
'Ah!'

　Yae's Schwertrite and Hilda's Sieglune are Babylon's hangar. I had to transfer to the surface world's Babylon once and bring them to the surface world's Babylon in an alternate space transfer.
　If this is the case, I should have put the two aircraft in [Storage] as well. Or rather, should I have put it in the 【Storage】 that was granted to the two engagement rings? Well, it can't be helped. Even if it's just me.

Come on, come on, come on!　I'm stuck, I'm lost, I'm in trouble!　There's a big sister you can count on who will answer you when you call on her!
Wow!

　I almost fell off the roof of the building when I was suddenly shouted right beside it.
　I'm not going to be able to get a good look at it. When did this happen?

"Sister-in-law Aneue-dono!
''Sister-in-law, ne'er-do-well!

　Yae and Hilda are also looking at Hanakoi's sister, rolling their eyes. It's really a person who's a godsend, that's the right word for it!　It's not a person!

"Hanakoi, what are you doing here in the underworld?
''Sis, your radar beeped at me. Fuyao-kun is crying and in trouble. We must go help him!　And!

　I'm not crying. Either that radar is broken or it's "something interesting is happening! That's a field radar!

That's why I brought Babylon into the underworld," he said. Hola.
''What?!''

　She said that, but there was nothing in the place she was pointing at. It's just a thin layer of cloud cover.

There's nothing to see here, but...
You should see it in 'God's Eye'.
Oh, okay.

　Is it because of the stealth function installed in Babylon? When I activate the "God's Eye", Babylon is indeed floating in the air. Or rather, that thing was just transferred to another world.... It's still impossible for me to do that........
　I mean, isn't this using divine power?　Using divine power to interfere on earth (except for me, the apprentice) is not allowed (except for me, the apprentice).......

''........That thing belongs to you, Fuyao?　So it's owned by God (the Apprentice). So it's not an earthly property, so maybe ok!

　You're being ridiculous!　I bet you just figured that out!　I'm not looking away!
　Enough. There's no point in biting into it. Anyway, I send Yae and Hilda to Babylon with [Gate], and I turn my attention to Hekatoncale, which is about to ramp up.
　Hecaton Cale spread its wings wide and floated up into the air. It's probably not flapping its wings with those wings, but rather forming a kind of anti-gravity field to float.
　Tee, 【Slip】 wouldn't work with that one. With that size, 【Prison】 would be weak in strength, and it's impossible to deploy 【Gate】 on the ground and drop it somewhere else.

''Well, that's something we can do, though.

　I call out my frame gear, Regingrave, to the square of the capital, which was empty after people fled from [Storage].
　I immediately get into the cockpit, set my phone to the console, and activate the Regingrave.
　Images of the outside appear on the monitors around me. While catching the Hecaton Cale in front of him, he poured his magic power into the control stick and lifted the Regingrave into the air.

''Activate the Flying Manipulator [Fragarach]!
Fragarach is now online.

　With a bang, the twelve crystal plates attached to Regingrave's back were detached. The long plate shaped crystal plates began to slowly rotate around Regingrave like a satellite.

''Shape Change [Mode Change], Sphere [Sphere].

　The plate-shaped crystals turn into spheres. The twelve crystal spheres are lined up in front of me like a clock face.

''Okay.''

　Twelve bullets struck Hecatoncale, but the crystal ball hit the invisible barrier and did not reach Hecatoncale.

''Hmmm?''

　The Mage King, who has become the brain of Hecatoncale, has noticed us. I fly my Regingrave and reach the top of Hecaton Cale's head.
　You can clearly see how big it is from above.

'Kaka. So that's the golem you found?　Well, it's certainly a rare golem I've never seen before. But it's no match for this Hecaton Cale?
Really?　I guess it's better than the big, useless antiques.
"Not less, but more.

　The Hecatoncale is flapping its wings and closing in on Regingrave.
　I ducked the Hecatoncale's attack and sent Regingrave towards Hono, which is some distance from the capital. I lure Hekatoncale to the opposite direction of the place where I transferred the people of the castle to.
　Is it okay to riot a bit here?

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

　The twelve crystal spheres that were spinning around me split into four, each one transforming into a dagger shape. A total of forty-eight daggers radiate out around Regingrave.

''Shinui Fuyou. [Meteor Sword Group [Gradius]]

　Forty-eight daggers clothed in divine qi were released at once towards Hecaton Cale. The forty-eight holy gleams struck the mischievous multi-armed demon.

''Kaka!　Don't you dare!　In front of Hecaton Cale's defensive barrier, such a thing, nah, nee!''

　The invisible barrier that Hecaton Cale deploys is easily broken through, and the crystal dagger pierces its body.
　It's a good idea to have a good time with them.

''What's going on!　I'm not going to penetrate Hecaton Cale's defensive barrier...!　What the hell are you doing?　Tell me!
f*ck it.

　The crystal dagger that flies around in every direction is filling holes in Hecatoncale. However, since the body of the dagger is so large, it is not a decisive strike. On the contrary.........

''A self-regenerating function........''

　Among the golems of the ancient aircraft 《Legacy》, there are not a few aircraft that have a function to repair even a few scratches.
　However, that's only to the extent that it can be repaired even if the body is scratched, and it shouldn't be a function that would be enough to fill the hole that was drilled into it.
　If we go that far, it would be the same as the 'Mad Lady', Luna Trieste's purple crown, and Fanatic Viola's super regeneration ability.

'The bigger you are, the more self-renewing ability you have?

　The hole in the body opened by the [Meteor Sword Group 《Gradius》] is being closed up. At least the surface was regenerated. Although I don't understand the internal functions of the body.

"Lick it!

　A beam of light emanated from the palm of the arm, Hecaton Cale's arm, like a beam of light. A hundred strands of light attacked Regingrave from every direction at once.

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

　The forty-eight daggers combine into six crystal plates, eight at a time, and bounce the beams that fly around Regingrave as they go around him.
　The rain of beams is shot out without interruption, but it never reaches Regingrave.
　And then one of the arms that was shooting out that beam was cut off from the elbow.

"What?

　The purple armoured warrior who cut it off. It's a double-layered Schwerdtite. Then the other arms were slashed off by another plane as well. This one is an orange plane. It was Hilda's Sieglune.
　Both of them were equipped with units with verniers on their hips and legs. Two planes without the ability to fly were enabled by that thing to fly.

'So it was complete, that one.

　The only people who could do aerial combat in a fight against mutants were me and Linse. Therefore, inevitably, the flying mutants were usually dealt with by us or by Leen, Yumina, Lou and others who had ranged capabilities.
　That's where Rosetta from the 'workshop' came up with that equipment. It's a convenient piece of equipment that allows non-flying frame gears to fly as well, but it can only be moved for a short period of time, and it's basically a special-purpose machine dedicated to the "Valkyria" (it's complicated).
　Using that unit, Schwertrite and Sieglune ducked under a rain of beams and slashed Hekatoncale's arms one after another.
　With their skills, it's not difficult to slash through defensive barriers. As expected of Hecaton Cale, it seems that even Hecaton Cale doesn't seem to have the ability to regenerate the arms that were cut off.

''That's ridiculous!　Hecaton Cale is the most powerful golem in the world!　The ancient wisdom and I, the Magus King, have created a matchless golem!
You just took something that somebody else built and turned it into something else. What are you talking about? Why don't you just build something from scratch?

　Engineer Elka is also trying to build a golem that will surpass the ancient aircraft, but it is only as an original creation of his.

You're the one who modified it so it's no longer useful.
"You don't...　Eagle!　Do you mock me, the master craftsman!　No!　You can't do that, kid...!

　Hecaton Cale lets out an angry yell from the pit of his stomach.

'I'll give you hell, kid!　Savor this Hecaton Cale's golem ability "skill"!　'The name of the decisive weapon is not an honorable one. Even with thousands and tens of thousands of golems, you will find that you are no match for Hecaton Cale!

　Immediately after, green smoke blew out from Hecaton Cale's entire body and began to drift around the area.
　Don't tell me it's poison?
　However, the special machine that Yae and her team ride on, no matter if it's an old-style frame gear, is equipped with a special filter. The poison shouldn't be able to penetrate into the cockpit. However, as a precaution, I'll call Yae and the others back here.

''Neither of you have any physical changes?
'No, nothing. No problem.
"Me too.

　You're okay. But what's all this smoke?

"Kakaka!　What's going on?　Are they going to attack us?　How do you feel when your golems don't do what you want them to do!'

　?　What are you talking about?　I'm not sure what he misunderstood when he saw us watching, but the Mage King is laughing at us.

'Kukuku, this smoke has the power to paralyze the Q-Crystals, the brain of Golem. It can infiltrate any opening, penetrate the nerve lines, and erode the Q-crystals in the blink of an eye!　Your golems are just iron scraps now.
...shape shift, assault spear, lance.

　The crystal plate that had been circling around Regingrave overlapped with his raised right arm. In the blink of an eye, the right arm took the form of a long assault spear, a lance made of crystal.

''What?　What do you mean?　Any Q crystal should stop functioning!　No gollem could resist.　How can it move?　That's impossible!　This can't be happening!
I don't remember us saying anything about this plane being a golem.
"...Wha...?

　Unfortunately, I don't use any Q crystals for my frame gear.

"Nonsense... it's not Golem?　So, what in the world is it then...?　If it's not a golem, what is it?
I don't have to answer that question.

　The vernier on the back was set to full throttle and further accelerated with [Axel]. The Regingrave, which turned into a single assault spear 《Lance》, thrust its tip into Hecatoncale's chest.
　With the momentum of the assault, it went through the interior of Hecatoncale in a straight line, and I expanded the size of the assaulting spear from the middle. I made the spear look like an umbrella opening up, expanding the area of damage and eventually penetrating between the wings on my back.

'Nonsense...!　'Nonsense!'

　Hecaton Cale, who had a wind hole in his chest, lost his balance with a wobble. Apparently there was a function that controlled gravity control at the place where it was destroyed.
　The Hecaton Cale falls down. With a loud earth shaking, the multi-armed demon exposed its corpse to the earth.
