Dancing Circles on the Horizon of Events

Quinn...

A mass of metal (manoeuvre armor) that flies at intense speeds, raising the sound of armor in the midst of a large, almost cloudless sky.

On its back was a figure of waltz royal with a cool face as he pushed the impending atmosphere through with gravitational control.

"Hmm. Sylvia's gonna do it inside too..."

Speed had already crossed Mach 2, entering the realm of authentic, ultrasonic speed, but Waltz muttered when he saw Silvia steadily increasing speed nonetheless.

I guess this means Sylvia's seriousness, which she can't do other than fly.

(I'm not winged, but accelerating is... um, well, it's a different world, and that's what it is...)

Earliest, hydrodynamics, aerodynamics, thermodynamics... no, before her flight ignoring physics in general in the first place, waltz to stop analyzing.

"... Oh, you've seen Lucia, too. Does that mean Sylvia is faster than Lucia?

When Waltz is surprised by Sylvia's good fight,

"Um... Master Waltz? Ladies and gentlemen, are you traveling at this rate from time to time?

I heard those words from Yuki, who was grabbing them with his left arm.

"Hmm, this is the first time Lucia and Sylvia are racing, right? I mean, until now, I've been carrying... When we travel long distances, we might travel at this speed or a little faster..."

"What, faster?!?

"Yep. When you're in a hurry, you fly much higher than here. It's easier to fly with less air resistance that way... but it looks like the two of us don't know yet (if we fly without measures at too high, the air might be too thin to suffocate...)"

"Even now, the scenery is flowing at an amazing rate... I can't imagine being faster than this at all..."

Yuki looks not only at Lucia and the others, but at the scenery around her as she is grabbed by Waltz's arms.

Maybe she's looking for where the streets she's been walking.

After a while...

"Oops? You're slowing Sylvia down..."

Around 400 km from Wang capital, Sylvia's health reached its limit.

"Totally... I told you to leave your strength behind because you'll be flying fast later... I don't mind."

So whining, Waltz approaching Sylvia.

"Yes, secure"

"Ha, ha... su, sorry. Almost there, I thought I could catch up with Lucia..."

"If it was only the highest speed, you'd have been faster than Lucia."

"Ha, ha... ha, yes. One, I'll try to catch up next..."

To put it that way, Sylvia untied her angelization and fell asleep on her back with manoeuvred armor.

"Well, Lucia next..."

With that said, waltz to accelerate even further.

"The truth is, I don't really want to get speed at such a low altitude."

"What do you mean?

To Waltz's words, Yuki speaks the question

"Well... if you look behind you, you'll see, right?

"Behind?... what!?

And Yuki noticed.

... the trees in the woods on the path the waltz came through, for the sonic boom, are now blown away in a progressive form...

"Hey, what is it..."

"Hmm, if it's easy to say, can you tell if we're too early and the wind that we built on that momentum is blowing up the trees...? If we keep doing this, we'll just have to prolong the natural destruction, so let's just get Lucia."

Gas Turbine Boost Y/N Y

Anti-Gravity Reactor Boost Y/N Y

"CODE: 1001, 3032 Accept"

Dgowwwwwwwwww!!!

The color of the flames blowing out of the legs of the manoeuvring armor changed, and at the same time, more layer, the scenery around them was left behind...

... and five seconds later.

"Yes, I got him"

Oh, sister!?

After catching Lucia with a holographic arm, Waltz rises all the way up to altitude where the effect of the sonic boom on the ground is attenuated enough.

"No, Lucia. I told you to think about Sylvia and Julia.

"Ah... yeah... sorry..."

Seeing Sylvia breathing constantly on the back of her manoeuvred armor and Julia grinning bitterly at her right arm, Lucia leaned over with apologies.

Though, in this case, Lucia wasn't the only one to blame.

"Well, Sylvia and the others were the first to stir it up."

That's what Waltz said, glancing at Julia and Sylvia.

"Shh, excuse me... Shh, next time must be..."

"No, junior... I don't think it's Sotch"

"Um, not at all... It's good to forget me and race, but you have to do the time and case (TPO) to avoid affecting the people around you and the natural environment, right?

... Note that the word can be that Waltz himself tasted and said by his brothers and sisters.

"Yes..."

"Ha, ha no..."

"Excuse me..."

(Regardless of Lucia, the name can be raised around Sylvia as a brave...)

Waltz thought that before the soggy three...

"Well. We're moving on to high-speed flight, right?

"What... we accelerated earlier, didn't we?

Within a dozen minutes of leaving the Wang capital, Yuki said as he saw a familiar mountain range passing by.

"If you're traveling ultra-long distances, there's a way to get around them. Ma, I can't do it in the atmosphere, so I needed to get a little more advanced, but... I figured I'd stop it."

"What...?

To Waltz, who suddenly told me to stop, why? with expressions like that.

"... because I'm not the Great River?

That being said, Waltz, standing on the head part of the manoeuvre armor, pointed to the end of the horizon.

Apparently, Lucia and the others flew too fast to the Great River at once.

Lucia squeaks when she sees the sight at her sister's fingertips like that.

"... a bright red river...?

Yes, a river as red as blood was flowing, as if to divide the continent.
