Dancing Circles on the Horizon of Events

"Oh, sister... shrunk?" Bun......

Lucia, bewildered, moved the Waltz thing onboard.

Then Waltz, in a hurry--,

"I'm sorry, Lucia. Explain later!

"Ugh, yeah......?

—— and only a brief exchange with Lucia, flying from the room with the laser launch point to the ship. We rushed to the pantry to make supplies.

"... Hey, Teresa. What's going on with that sister?

"... the concubine would like to hear it."

"... I agree with you."

Three people who don't know why the waltz has shrunk and drop off the waltz that disappeared onboard. At that time, all three of them were losing their words because their appearance was too shocking?

Lucia was the first to return it to me afterwards. She raises her voice in a panic.

"Oh, yeah! You know, about your sister, you should go after her, right?

In contrast, Teresa shakes her neck sideways.

"I just told you, don't you want me to move from here? Maybe when you get back, you'll ask me to go outside again?

"Oh well..."

"Mm-hmm. And... they're going to hang a sudden brake on this Strangea, so we were talking about a lot of shocks. So Waltz told Miss Lucia to use gravity-controlled magic to protect herself so that she could withstand the brakes."

"Brakes?"

"Mm-hmm. Now this Strandia is traveling at an unbroken speed of tens of thousands of kilometers an hour. Maybe the concubines are fast enough to circle the stars. So they're gonna hit the stars like this, so they're gonna hang the sudden brakes?

"Hey, that, I don't know, I mean, what do you mean?

"Well... I mean, the concubines are now moving about 10,000 times faster than the carriage, so if you were to hang as steep a brake as the carriage from there... does it feel like the impact of the brake would last for about two hours?

"... is that a sudden brake?

"Maybe the shock is a little stronger, and it'll take about an hour."

"... I don't think two hours or an hour will make much difference..."

Because we didn't know how fast we were moving right now, the word "sudden brake" itself didn't seem to swallow well for Lucia. The countless stars visible on the other side of the window could not move and see at all because the distance was away in light years, and she could not grasp the distance or the speed.

Beatrice, on the other hand, seemed to be able to grasp the general circumstances from Theresa's description, either because she had recently started studying physics at Catalina's and Yuki's.

"I mean, you have to slow down rapidly in a short amount of time for days to come, right?

"Hmm. That's what I'm talking about."

"Yeah, I think Bear's explanation is much easier to understand"

"... I'm sorry it was so hard to understand." Mmm.

"Well, well. So, with a lot of slowing down, Lucia has to use magic to protect us."

"Yeah, leave that to me? Because I'll protect you properly."

and Lucia turning her grin toward Beatrice. Theresa seemed to be in a bad mood because she was in such a way that she was ignored.

By the way, Teresa's explanation is incorrect. She seemed to estimate the steep brakes on the carriage to be between 0.5G and 1.0G, but in fact, it adds an acceleration to it that resists the gravitational pull it receives from the planet. In other words, to zero the relative velocity to the planet in two hours, it would take at least 1.5G; to zero in an hour, it would take 2G. Well, in fact, it shouldn't be a situation where the brake lasts for more than an hour, as force should be applied in the direction of deceleration while bending over the course avoiding collisions with the planet, rather than slowing down in a direction that would make the velocity zero.

Understand what Lucia and the others will be attacking themselves (?) When I did. Waltz, who disappeared across the dark, returned with tremendous momentum.

"Lucia! I'm sorry, can you get me out again? Because I don't mind on the other side of that glass."

Lucia nods quickly at her sister who speaks so... Until the question I had, I couldn't seem to convince myself.

"Sister... the way she looks..."

"Um, well, people have a lot of things, right? If we make it back, I'll explain everything?

"Ugh, yeah... ok. Absolutely, right?

"Yeah, absolutely, right? We're definitely going back together. Come on, please"

"... yeah. Good luck with that, huh?

Lucia nodded as if to pay her worries--,

Bun......

He sent the Waltz thing back to the black world that spread across the glass.

And their last operation in space opened the curtain.
