Hitoshi also tried a few experiments under microgravity conditions.

For example, fire. He tries lighting a twig on fire with magic.

"Oh, that's interesting!

Saki said, pointing her finger at the twig. I set it on fire, but it did not burn up. It turned into a round shape and soon disappeared.

"Hmmm... I guess, since there is no convection of air, it must have gone out soon after it ran out of oxygen."

"I see."

While he was doing this kind of experiment, the old man reported to him.

<

"Oh, I see. Well, let's go see it."

"Oh, I'm looking forward to it!"

"I wonder what it's going to be like."

As the four of them land on the floor, the old man slowly restores gravity.

"......I'm feeling kind of heavy."

"Yeah, I agree."

"No wonder your bones become weak if you stay in the weightless condition for a long time.

When Jin mentioned in a whisper what he had heard when he was in modern Japan, Reinhardt and Saki asked in surprise.

"What?

"Jin, Jin, what is it?　I heard something not so peaceful...?"

"Oh, that's ......."

Jin explained as he walked along that bones support the body, but when the burden is removed, they no longer feel the need to maintain their strength, and so their strength weakens.

"Hmmm ......."

"So, what you just said was a training exercise for emergencies, not to stay in that state by any means."

"...... gepu."

Saki, you're being rude.

"No, excuse me, excuse me."

Saki burps while walking and Erza chastises her.

But what they don't know is that when you burp in zero gravity, the air, which is the body of the burp, comes out without separating.

They are lucky that the liquid and solids in their stomachs also come out together. ......

That they were lucky. .......

"Oh, my God!　What the hell!"

"Rai, shut up. Saki, take a cue from your sister."

"......"

"No, Erza-sama, with all due respect, I think Saki-sama is just letting her mind wander."

Saki is quiet, and it seems she was stunned by the sight of the 300-meter-diameter spherical ship .

Then he started over.

"...... Gin, this is awesome!　This is too much!　What a thing you have made!"

Reinhardt calmed down a bit, but was still very excited.

"Oh, my God! It was more than I expected, more than I expected, Jin.

Saki was completely taken aback.

Jin explains to them politely.

"The old man and Reiko both said that it's not safe for me to go out into space unless I have this much ......".

"Oh, that makes a little sense."

"Yeah, yeah."

Both of them are convinced by Jin's half-excuse explanation, because they both know how much the old man and the others care and cherish Jin.

"Hey!

Jin asked, "Are you listening to my explanation?

"Yes, I'm listening to you. Yes, I'm listening to you. Can we ride with you?

"Of course we will. There's nothing wrong with the engine, so as soon as we get the interior done, we'll invite you all aboard. Let's all go to space!

"Oh, I'm looking forward to it!"

"That's very exciting."

While Jin was explaining to Reinhard and Saki, Erza was talking to the old man.

"...... So, not only ultraviolet rays, but also visible rays are harmful."

<<

"Does this mean that the environment of space is harsh after all?"

It seems that they are planning some kind of countermeasure here.

* * * * * *

"I like hot springs after all."

Reinhardt decided to stay at Horai Island that night and was relaxing in the hot spring.

"...... So, Jin, when are you going to have the wedding?"

Reinhardt asks Jin who is in the hot spring with him.

He was indeed not able to make fun of what he was talking about,

"Well, I was thinking autumn, but maybe summer. ......

Jin replies in a matter-of-fact way, "Well, I was thinking of autumn, but maybe summer.

"I'd like to think about it after the moon survey."

He is thinking seriously about it.

"Erza's presence has helped me a lot, and I'm sorry that I seem to be procrastinating," he said.

Reinhardt was pleased with her honest reply.

"I see. Well, in the end it's between the two of us, so it's not my place to say anything about it.

Saying this, Reinhard patted his stomach.

"Is it getting a little tucked in?"

Bertsche pointed out that he had been doing some exercise in between his duties.

"Bertsche's belly is getting bigger, isn't it?"

"Yes, she is."

Reinhard smiled happily as he soaked in the hot water.

Seeing his smile, Jin suddenly wondered if he could make a family like theirs.

Meanwhile, Saki and Erza were bathing together.

"Ah, hot springs are so nice, aren't they? It is different from just hot water.

Saki said in a deep tone as she caressed her left arm with her right hand.

"I'm glad that Erza and Jin seem to be getting along well.

"...... Saki sister, how are you and Goose-san?"

I'm not sure.　I don't know, I don't know. I don't really know either, that's the truth.

Saki gave a carefree smile.

"From my point of view, I think Saki and Mr. Goose are a good match.

"You think so?"

"....... It's not for me to say.

It's not up to you. Elsa's a lot more mature than I am.

"......No, she's not."

Saki gently stroked Erza's head as she looked down at her.

I'm ...... sure it's because of Jin. I'm a little envious of you.

"Saki, my sister. ......"

Erza turns bright red.

"Ha-ha-ha, but you're still the same old Saki.

"...... already."

The wind on Horai Island is warm, and the night reminds us that summer is about to arrive.
