An ordinary profession creates the world's strongest

Hearing this, Hajime quietly averted his gaze. His father had hit the nail on the head. In reality, Hajime was indeed planning to build another refinery and other facilities to carry out a plan he'd be working on after he finished his work.

"A secret room or a refuge room hidden behind a revolving bookcase is so romantic! Let's make a room for our parents too! I want it! I want it!"

"You're not a child."

"Mom wants the Roman Baths. If you don't agree, I'm going to publish a fanfiction of yours! And I'm going to put all my effort into it, a professional manga artist-level one!"

"That's terrible."

The Nanyun family always gave their all to anything they enjoyed and enjoyed, whether good or bad. Father Cho and Mother Sumire's eyes sparkled with joy, like young boys and girls.

Of course, Yue and the others also looked excited and expectant.

Surrounded by everyone's expectant, shining eyes, Hajime felt a little embarrassed, but...

He was still a son of the Nanyun family after all. After a pause, he spoke.

"...Fine, you can build as many basements as you want. In that case, I'll fulfill everyone's expectations and build the underground space everyone has been dreaming of!"

“““““Oh yeah────!””””””

Yue, Tio, and Myuu cheered loudly and innocently, and Remia, who was a rare exception, also joined in. Everyone raised their hands high, smiling broadly, looking genuinely happy.

However, Yue and the others were definitely not truly happy because their wishes had been fulfilled, but because──

"My dear son, Daddy knew you would say that! So, we've already prepared the blueprints!"

"Look at this flawless division and planning of the rooms. Not only does it satisfy everyone's needs, but it's even playful enough to make visitors feel a sense of unnecessary strangeness when they enter, like, 'This house... seems a little strange...'"

"Dad, Mom... you're truly worthy of me! That's what makes me admire you! I admire you so much!"

"Don't flatter me!"

It was because Hajime was between his parents, arm in arm with them, smiling genuinely happily.

That kind of even innocent smile was something she had never shown in Todas.

Seeing him display this somewhat childish side made Yue and the others very happy from the bottom of their hearts.

At the same time, they also gained a better understanding of Hajime.

Understand that this was the life he had been living before he was called, and understand how precious these days were to him.

Because Shi's parents are such people, Shi can firmly believe that his parents must have been looking for him.

That's why Hajime wanted so desperately to return to his original world.

What he wants to get back is this kind of daily life.

"Hmm? What's going on? Yue, Shia, Tio, Myuu, and Remia."

When Hajime was about to turn around and walk out of the living room, he noticed Yue and the others standing still, watching Hajime and his parents from a distance, their expressions as happy as if they were filled with honey.

Seeing them like this, Hajime turned around with a puzzled look on his face and asked.

"You guys come over here too. Quickly."

The beloved narrowed his eyes and waved.

On his left and right were their father-in-law and mother-in-law, who were also waiting for him, their warm smiles like the sunshine.

Yue and the others glanced at each other, then immediately narrowed their eyes and smiled at each other. Then—

“…Yes! I’ll be right there.”

“It’s~ Hajime-san~!”

"Haha, this is the first time the whole family has done homework together!"

"Hmm! Grandpa! Myuu wants to see the blueprints too~!"

"Aiya~♪ Myuu, don't pounce on me."

The five of them ran towards Hajime simultaneously, looking genuinely happy.

Volume 14, Chapter 3, Holiday at the Nanyun Family

Refining magic—this was the pinnacle of Hajime's crafting and processing skills, even allowing him to annihilate a god from another world. Seeing their son unleash this skill to its full potential in their basement, Cho and Sumire were naturally overwhelmed with excitement.

Influenced by his parents' excitement, Hajime's interest also reached its peak. Yue and the others were currently lacking common sense about Japan, so naturally they were unable to stop them.

Therefore, in the end, a five-story basement was built underground in the Nanyun family, which was wider than the original land of the house (the entrance and exit of the basement was transferred, so the basement was actually built from 50 meters below the ground below the house). Such an absurd space was, from a certain perspective, an inevitable result.

The basement houses not only Hajime's bedroom, a workshop, and his parents' studio, but also a training ground (including a shooting range), an arcade, a theater, a nuclear shelter with many parts that can be deformed and adjusted (this is the result of abnormal emotions like staying up all night for three consecutive days), a hobby room (collection room) that is extremely sophisticated in every aspect, and a large library.

The neighbors certainly couldn't imagine that overnight a comfortable and convenient secret facility had appeared deep underground near their homes.

Hajime openly completed this illegal construction deep in his basement, and the next day—

"Did I go too far...?"

He sat on the sofa in the living room, tilting his head and hesitating.

"And in the end, my main room is still the same as before..."

As he'd said, he continued to use the room originally on the second floor. "If Hajime wants to live in the basement, we'll have to live in the basement too!" Yue and the others insisted, and no matter how they tried to persuade him, they wouldn't listen. If that happened, all eight of them would live in the basement, and the ground floor house would become a mosquito den. It was completely putting the cart before the horse.

"Hehe, is your husband dissatisfied?"

"Dad, don't you want Myuu to live across the street?"

The door to the living room opened, and Remia and Myuu walked in. Myuu jumped onto Hajime's lap, puffing out her cheeks and looking dissatisfied.

Hajime poked her chubby cheeks with his fingers to calm her down, then shook his head and said:

"No. I've grown attached to this room over time, so of course I'm not dissatisfied. Besides, things like basements only gain value when they're rarely used."

"That's great. I was worried that I might be asking for something a bit too much."

"Remia, you guys really don't mind? In the end, the three of you still have to share a room with Tio."

Of course, Yue and Shia were still sharing the same room. However, Remia gently approached and sat down next to Hajime, leaning particularly close. Then, she slowly shook her head and said:

"No, I have no complaints at all. Besides, chatting with Miss Tio is always fun, and we often chat until late at night... Oh hehe."

It's like being a child again—Remia said this with a smile. She didn't seem to be giving in at all.

"Sometimes it's fun to switch rooms with Yue and Shia!"

"Is that so? That's good."

Myuu said, sitting on Hajime's lap, hands raised. She didn't seem to be unhappy at all. It seemed Yue and the others weren't too bothered by the idea of ​​sleeping in the same room with others.

"What about Dad? Will he be lonely?"

The little girl was worried that her father would feel lonely sleeping alone. That worried look touched Shi's heart as a father.

"Myuu, men have many difficulties, and sometimes they need to be alone."

"Is that so?"

Before Hajime could answer, Remia's mother rushed in to explain this to Myuu, leaving Hajime stunned.

"Yes. Especially since your father has a hobby he really enjoys, and he needs some alone time to enjoy it."

"Alone? Can't Myuu be with daddy?"

No, that's not true… Hajime instinctively wanted to deny it, but before he could open his mouth, Remia beat him to it. What Remia said next shocked him greatly, to the point that it was like the "divine words" of the god Esid.

"No, Myuu. It's too early for you. In this country, even in creative writing there is an 'age limit'."

「!?」

Hajime's shoulders twitched violently, and his eyes darted wildly, clearly looking like he was thinking at high speed.

Why? Why? Why did Remia say that!? Did she find out!? Did she find out about my collection!? Why!? How could it be!? — Hajime was clearly wavering.

"Hmm!? I see~ There are things Myuu can't see yet, right? Then, can't mom and sisters watch it with dad?"

"...Hehe, sure. As long as Daddy wants it. Right?"

Remia's mother turned a pointed look towards Hajime's father. Myuu then looked back at her father, her expression tense.

"D-Dad? W-What's wrong with you!?"

"What do you mean?"

"Dad, you're sweating so much! It's like a waterfall!"

"Haha, you read it wrong. Daddy is fine. Daddy is very healthy."

"The way you talk is weird too!"

Myuu immediately took out a handkerchief and wiped Hajime's forehead with a worried look on her face. Hajime's face was stiff with a dry smile, and he looked at Remia's cute yet scary smile.

"Oh my, oh my... Hajime-san, I'm so sorry. A while ago, when you were busy... Grandma let me see your collection. For example, the so-called 'books' and 'adult games' and the like."

“Mom────! Get out of the basement right now! How did you even know where I hid my stuff?! Depending on the situation, I might end up severing ties with you!? Hey──!”

"Uh, Hajime-san! Please, please don't blame grandma! We were the ones who pestered her to tell us about our husband's sexual quirks!"

“What did you two talk about while I wasn’t home?! And do you normally ask someone’s mother about things like this?! From a son’s perspective, this is pure hell!”

Even though he was still holding Myuu, Hajime couldn't help but stand up. His face flushed, a rare blush. Myuu also looked deeply interested, seeing her father's rare expression. Then, Myuu's expression suddenly turned firm.

Her expression clearly showed her determination to find the truth. What exactly was this "hobby" that could make her father so shaken? She had to explore it! However, Hajime, who was now in a state of panic, did not notice Myuu's thoughts. At this time—

“Ahahaha. I’m so sorry for investigating something like this without your permission, Hajime-san.”

"I'm sorry, Master. It's just that we are truly curious about what kind of life you led before being summoned... That's why we want to know."

“…Um, Hajime, I’m sorry. Who told Kaori to always show off her superiority to me, acting like she knows more about you in Japan than we do? I really can’t stand it. So, no matter what, I want to know everything about you. Everything.”

Xia, Tio, and Yue came into the living room one after another.

Especially Yue's mumbling after his defense revealed an unpredictable emotion, which immediately made Shi lose his excitement. He even shuddered slightly.

"Even so, you shouldn't..."

"……and."

"What? Anything else?"

Seeing Yue looking up with a guilty look on his face, Hajime couldn't help but become alert. Yue's eyebrows drooped into an eight-shaped shape and she confessed to him:

"...We asked our father-in-law to let us look at the photo album."

"Photo album? That's fine, it doesn't matter—"

“…When Hajime was little, he was really cute… The bathing photo is also… Hajime’s little Hajime was really adorable.”

"What are you talking about!?"

"...Completely different from now. So cute I want to eat her in one bite...though I'll still let her eat me in the future."

"Stop using vulgar language, you erotic vampire princess! Myuu is still here!"

"...My father-in-law also made a copy of the photo for me. It's my treasure."

"Throw them all away! Now! Immediately!"

Yue had always wanted to know what kind of person Hajime was before he was summoned. Besides that, he had even thoroughly observed Hajime's childhood. It seemed the charm of the young Hajime was enough to make Yue lose his mind.

And it seemed that Xia and the others had seen the same thing. They all blushed and looked away.

"Also, Master. I'd like to take this opportunity to make a statement. I'm always happy to accompany you in those 'books' of yours that are beyond fire—"

"If this doesn't stop, I'm really going to turn into gray-haired mode."

That is combat mode.

Hajime's cheeks twitched stiffly, and his hands, which were busy covering Myuu's ears, clenched into fists tightly. It was probably only a matter of time.

"I'm sorry." Yue and the others apologized in unison, even Remia.

Remia had taken the liberty of looking through Hajime's collection and confessed without reservation. Yue and the others also openly admitted their guilt and apologized. Everyone simultaneously created an atmosphere where they wanted Hajime to forgive them.

And Shi himself couldn't help feeling a little guilty about the fact that he still kept the collection even though he had a partner like Yue. Coupled with the intense shame at the moment, he didn't know how to deal with his emotions.

“Uh, uh… ah, right~!”

Myuu didn't know what was going on, but she could tell the atmosphere was incredibly awkward. From her perspective, she naturally wanted to change the situation. So, she jumped out of Hajime's arms.

"Dad, look! How about Myuu's clothes? Isn't it cute~?"

Miao turned around, showing off her white women's shirt and plaid skirt decorated with ruffles.

I felt so ashamed that I had to make a little girl worry. ——Realizing this situation, Hajime and the others looked at each other and smiled bitterly.
