The body shape and physique are almost the same as Elsa's, so all that remains is the hair color and length, eye color, and so on.

"Let's keep her voice the same.

This was done by Jin, who wanted to make her voice the same as Elsa's. Also, the voices are different in quality.

If the voices are different in quality, there is a possibility that the voice will be mistaken in case of an emergency.

The same goes for the appearance.

Almost no one knows Erza's face (only those related to Horai Island). So there is no problem.

However, the color of her hair and eyes will be recorded, so we need to change them.

The color should be black. Same as Jin's brother. Eyes too."

"I see."

Jin was thinking, "They'll be like brother and sister,

He says, "We can say we're from the same hometown."

Jin says, "We'll be like siblings.

They are childhood friends. So they will still call him "Brother Jin".

"That doesn't sound so bad."

Reinhardt doesn't seem to have any objections.

"Besides, dark eyes and dark hair would make a strong impression, so it would be easier to remember him.

"Oh, and I was thinking of having him wear glasses. ......"

"Kuhu, then you and I will be matching."

Saki smiled at him.

"Yes, we do. Erna's glasses are date glasses.

Jin answered as he worked on the oval frames.

The frames were made of light silver, or titanium. The lenses are made of quartz glass.

The lenses are made of quartz glass. They do not have power, but they are curved instead of flat so that they look like they have power to the naked eye.

"Huh, now I'm wearing glasses, too, right?"

"Yes, you are."

Saki's nearsightedness was completely cured by becoming a homunculus.

Meanwhile, Erza had completed her appearance.

"Hmm, that's good."

"Okay, let me put on the glasses. "Oh, they look good on you."

Maybe it was because they were thin framed and black, but they looked good with his dark eyes and black hair.

"They look good, don't they?"

Reinhardt's words expressed the feelings of everyone present.

We also confirmed that it worked.

"......This is good. It's fine."

He can use healing and engineering magic just as well as he can, which will be useful for experiments.

"The sensors in the mouth and nose are especially sophisticated. But they are usually limited.

Jin said.

If the sensors are too sensitive, it will interfere with daily life.

"That's good."

Erza agreed.

* * * * * *

"Yeah, I did a good job today.

Jin is satisfied because he was able to make what he wanted to make. He soaked in the hot springs of Horaijima and relaxed.

"Jin, it just occurred to me..."

Reinhardt said while soaking in the hot spring.

"Yes?"

"I made a doppelganger for the family a while ago..."

Jin listened to what Reinhardt was going to say.

"You see, we have the same skin color and so on, don't we?"

"Yes, that's right.

"You know, if two or three people go together, don't you think they'll look too much alike, even though they're not siblings or relatives?"

"Oh."

Alone, that's fine, Reinhardt says, but if several people go out together, that could be a problem.

"......Well, let's just make one for everyone."

Reinhardt laughed and nodded at Jin's words.

"That's more like Jin."

* * * *

Jin who also eats dinner with everyone at Penglai Island.

"......I'm sorry, but the food at Horai Island is better than the one at home."

Hearing this, Soleil and Luna, who were in charge of today's cooking, smiled.

"That's because we know what Jin likes, don't we?

Reinhardt laughed.

"So, the Kingdom of Klein seems to be fairly well settled now," said Luis.

Luis said.

"But there doesn't seem to be much progress in depopulation and redevelopment in the rural areas.

Licia says with some regret.

"Isn't it possible that as the population increases in those areas, they will naturally move into the rural areas ......?"

Toa said something like that, which was immediately denied by Goose.

"Father-in-law, an increase in population does not necessarily mean that people will go to the countryside. Concentration in cities is a more likely pattern."

"Is that so?"

"I see..." "Well, my father is not interested in anything other than alchemy when he is out and about."

Saki chuckled, "Even though they roam the same countries, Goose seems to see more of the world ...... than Toa.

"I've been thinking about it a little myself, and I think that in order to avoid concentration in cities, we need to have a better means of transportation."

Jin also shared his opinion.

"If we can use the warp gate for free, we can live wherever we want.

"Yes, I understand what Jin is saying. If that happens, I'm sure I'll want to live in a place with a nice environment and a nice view.

"But we won't get to that stage all at once. That's why we're having the developed as part of the redevelopment of Toka village."

Licia said regretfully.

"......We're not supposed to be here. It's up to those of us living in the present to change the world."

Jin says.

"I think it's just fine to give a little help to those people."

"Kuhu, I think you're overdoing it sometimes."

"Don't mix it up!"

Jin laughed at Saki's ridicule.

* * * *

Jin stayed at Horai Island that night and left the next day.

The time difference between Horai Island and Alban, the capital of Klein Kingdom, is about 2 hours and 40 minutes.

< stays at an altitude of about 5000 meters above the Klein Kingdom, it is enough for Jin to have a light lunch on Horai Island before returning.

" means that lunch will be served in Klein Kingdom.

"Elsa...... should I take Erna with me or not?"

That was the immediate question.
