"Well... shall we go to the heavenly side of the world tree for a moment?

'Hey, sister. Outside, it's dark... are you sure you want to go now?

"If you go out now, you'll be lost..."

Waltz's gaze, which came to the bridge of Energia, stared at the ceiling part of the hemisphere room, where the whole thing was monitored and showed the view outside. There it was as if it were a planetarium, illuminating the moon that was still going to sink and the appearance of countless stars. Well, it's getting pretty late at night, so naturally, naturally...

Do you really want to go to the heavenly side of the world tree at such a time? It seems that all those who were on the spot were leaning their necks, beginning with the energy of the girl. Or maybe everyone was thinking this. That is —— Waltz said without thinking, that momentum alone would rise to the heavenly side of the world tree at midnight.

But there, waltz, it seemed like he had an idea.

"Yep. Instead, it has to be this time. The universe is tougher than you think?

"Kakoku?

"Sort of harsh. The truth is, harshness is a super hard place for creatures, as easy as words can be. That's not the only reason we don't have air, by the way.

and waltz to look down at the faces of those on the spot who would have little knowledge of the universe and say so.

Then she began to tell us why, at this late-night hour, she wanted to go to the heavenly side of the world tree and why.

"Hey...... I think the energy guys barely know, but isn't summer hot? This way, the sun will shine brightly..."

'Mm-hmm... yeah. I think the radiator's gonna freak out. "

What's Bushi?

"Yes, yes.... or if it's going to overheat, say it before you do? Because the coolant in the furnace won't leak or spill..."

"Yeah. It's okay, it's okay."

"Then fine...... So, it's the light of the sun, but it's not like it's summer, so it gets stronger. There may be a slight difference, but even in winter, the same intensity of sunshine as in summer is falling."

'I mean...'

"Uh, mk1 again, I'm trying to say something crazy. Get out of the way...... was winter actually summer?! Or something you don't understand, do you?

'... if you go out into space, you're in danger because you get that sun directly,?!

…………

………… Did I say something weird? The fluidity of your sister's story made me feel like that... '

"Yes, no? That's right, isn't it? I was just a little surprised because they gave me the answer before I explained it in detail..."

"Yeah... something... sorry..."

"So, to be more specific, I don't usually see the stars we live in, but they're protected by things like junction magic and barrier. Because going to space means going outside the barrier, direct sunlight from the sun is already coming down with great momentum. Wouldn't it be burning before you feel hot or something?

'Hmm... I don't know, but that sounds like a lot of trouble, huh?

I understand, don't I? Anyway, if you accidentally go out there, you die, right?

"Yeah, right? But, well, in your case, I don't think it hurts or itches, do you?

".................. Huh?

Then the energy sisters solidify with a pompous look on their face just to say what the explanation was for until now. But soon they all seemed to come back to a convincing look with 'Ahhh', remembering that those other than themselves were there.

"That's why we can only go to space at night, as it is, without space clothes. Besides, considering the release of heat from this hull's fusion reactor, it's rather harsh at night. (It's not easy to get rid of heat in space...) That explains it?

That said, now Waltz turns his gaze from the energy towards the others who were on the spot.

In addition to Lucia, Theresa, the brave men, Cortex, etc., followed by Waltz at his direction... Everyone seemed to shake their heads vertically, even with Waltz's proper explanation, to understand the circumstances.

"Well, did you just leave?...... energy. We're heading straight up, please? That too, hurry because you have to go and come back before the sun comes out. If you don't come back soon, we'll all be steaming, right?

When I heard Waltz say ——

"What?!

Ha, go!

—— and, as he panicked, floated the hull in the sky, pointing straight at the bow of the ship towards the sky….

And ——

DOGOOOOOOOOOOOOOOOOOOO......!!

—— and a hull of energy that begins accelerating towards the heavenly edge of the world tree.

At that time, the acceleration transmitted to the ship had all been cancelled due to the gravity control system installed on board the energy vessel, so for those who were there, there was no real sense that it was launching towards the sky…. Seeing the stars and clouds flowing across the darkness, he just seemed to raise his voice of admiration.

Nevertheless...... That seemed to be a short story, too.
