Let's work hard!

Coming out of the train, they arrived at the Tokyo station and were greeted by many people. 

"Coming! Coming! Coming!" 

"A bento! If you are hungry, please come here!" 

"I am late! Please give me away! I am sorry!" 

Watching this crowd, Amane felt a little uncomfortable since quietness had been her every day, so this scenery threw her off. However, this wasn't her first time in Tokyo since, due to her husband's frail body, she had always been the one who was tasked to visit various places, whether it was to invite a potential Demon Slayer or meet with a high-ranking or influential individual. 

After all, while the Demon Slayer Corps wasn't a government organization, they were connected to a government and had been working together to support each other. 

The terror of the demon was real, and the Demon Slayer Corps' purpose was to fight the demon was real. 

With all of those factors, why shouldn't the government close its eyes toward its activity?

Moreover, the Ubuyashiki family was known for its frail bodies, and its members would die before they reached 30. Their obsession with erasing shame, known as Muzan Kibutsuji, was also well-known, so there was no doubt that the Ubuyashiki family was the perfect family to take the lead in this well-armed organization. More importantly, this country had always believed in ancestry. 

It was like how the descendant of the fast horse would be believed to be fast, or the descendant of the hero would become a hero. 

So, the Ubuyashiki family, which had been in charge of the Demon Slayer Corps for the millennium, was naturally more believable than supporting a stranger whose ancestry or attitude couldn't be guessed. 

"Where are we going?" Amane asked softly. 

Isao didn't answer this question immediately; instead, he lamented himself and felt slight regret. As he had taken the initiative to talk with her, it was impossible for him to act cold or even leave Amane at the station alone. 

"We will go to the city hall." 

"Okay." Amane nodded. "Do you need help?" Her family had a lot of connections, and those connections could help Isao to do a lot of things. Or rather, she wished for Isao to ask for help so he would ask her for help. After all, based on Isao's attitude, instead of begging him, it was better to help him sincerely so he would owe them a favor, and getting a favor from someone who could defeat all of Hashira with ease was definitely something that she and her husband couldn't ask for. 

"It's fine. I can handle it on my own." 

Isao rejected Amane's kindness calmly, but he knew if he accepted, the Demon Slayer Corps would help him with everything since they had that power. 

An organization that had existed from ancient times until now wasn't something that could be taken as a joke. 

The wealth and connections that had been collected from the Heian era until now were frightening. 

Moreover, the power of the Demon Slayer could easily match the power of tens of men and might even be comparable to the power of a small country in this era. 

So, owning a favor to such an organization was definitely troublesome. 

"Is that so?" 

While Amane was disappointed, she also felt curious, wondering how Isao was going to make his foundation in Tokyo. 

Was his family wealthy? 

Or was there something else? 

Amane would follow him no matter what, but due to how crowded the station was, she had a hard time following Isao. Unlike Isao, who was tall, she was pretty petite and didn't have much of an advantage in her physical ability, but when she was about to lose in the sea of people and panicked, thinking that she would lose him, someone grabbed her hand. 

"You should go back instead of following me." 

While holding her hand, his voice sounded so helpless. 

Yet, Amane looked at her hand, which was held by him, the man other than her husband. Instead of pushing him away, she held his hand tighter and lowered her head because she was afraid her expression would be seen. 

What kind of expression did she have at that moment?

Amane didn't know, but for one thing, she knew she didn't hate his hand, which gave her a sense of security.

"No, I will come with you." 

"You won't be living in comfort here." 

"It's fine. I will help you when you need someone." 

Amane didn't flinch away from his gaze and kept staring at his eyes. 

"Do whatever you want." 

When Isao turned, Amane smiled softly and let her lead him out of the station. At the same time, while she might appear caring, from their conversation, she could deduce that he was alone. She wasn't sure what was happening to him, but she knew that she had calmed down and she was no longer as nervous as she was before, yet instead of thinking to invite him to the Demon Slayer Corps, she was more cornered about his well-being, wondering what was happening to him. 

Amane didn't realize this, but this young man somehow slipped into her heart, which was only for her husband, without her even noticing it. 

As they walked, there was no doubt that Isao and Amane attracted everyone's attention. 

Even though Amane was a wife and a mother, she was a beautiful woman. 

On the other hand, Isao was a tall young man with a fair and handsome face. When the average height of people in the current era was just below 170 cm, his height was simply a magnet that attracted many to stare at him. 

While the women were attracted to him but couldn't do anything due to Amane's presence, the men moved away because a simple height difference would make them feel pressured and inferior. 

Isao ignored them and went to the city hall by a steam bus. Unlike in the modern era, the bus was petite, and it was still moving with a steam machine. Naturally, there wasn't even an air conditioner, but there was a natural wind from the opened windows. 

"You have never ridden this before?" 

While Isao lamented the current situation in this country, he saw Amane look around curiously. 

"Yes." Amane nodded. "I have always ridden in a carriage." 

As expected of a wealthy lady, Isao thought. 

"Moreover..." Amane looked at the scenery of the city. "Even though it hasn't been so long, this city has changed so much..." Unlike her place, which was still the same, the change in Tokyo was so huge that it made her unable to calm down. The world was moving into a different era, a new era that someone in the past never thought of.

This change slightly frightened her since it felt like she was being left behind. 

Subconsciously, she reached for his hand and held it tightly, giving her a sense of relief and security. 

"...." 

However, Isao was speechless. 

Hello, you are a married woman!

Still, Isao didn't say anything, thinking that even in the era of the past or in the future, the feeling between a man and a woman had always been the most intriguing and mysterious. 

Even a wife who was devoted to her husband and took care of her husband without any complaint was holding the hand of a man whose status was just a mere stranger just a few days ago. 

Frankly, they hardly had any conversations, and if there was a reason why she appeared so close, Isao thought that it was all due to how she had peeked at him and Kanae last night. 

Yet, it didn't matter since his focus had never been on Amane. 

This was Tokyo and the place of his beginning. 

So, after arriving at the City Hall, Isao used his ability to manipulate people to get him to register his citizenship and make him a Tokyo native. With this ability, even if he didn't spend money, everything was cleared up, and he was able to get his identity right away.

On the other hand, Amane became more curious about Isao's identity since she could see that he seemed to know the people in the city hall. Watching him talking with someone, she didn't say anything and just quietly waited. Soon, she watched him walk with a man in her direction. She hurriedly stood up and put a proper posture, ready to follow him.

"Let's go." 

While Isao put his hand on Amane's shoulder, gently leading her somewhere, the man who came with Isao gave a polite nod and said, "Please follow me." 

"Thank you." Isao nodded with a smile, but Amane was stunned by everything. As for Isao's intimate gesture of holding her shoulder, she didn't think much of it. "Where are we going?" 

"To my house." 

"Your house?" Amane was shocked. 

"Yes." 

Naturally, this shocked Amane since it was definitely not easy to get a huge house in Tokyo. However, she was even more shocked when they entered the car and had a man who had come with Isao before as their driver. 

Sitting in the back seat of the Pierce-Arrow Model 66, Amane was still in a daze as she watched this antique car bring them somewhere. 

Sneaking a peek at Isao, Amane understood that this guy was a descendant of a wealthy family. 

Soon, their car arrived in front of a house similar in architecture to Butterfly Manor in Shibuya City. As they passed Sakuragaoka Street, they saw many cherry blossom trees on the side of the street. 

Watching Amane's expression, Isao could tell that she wished to see them when they bloomed, but with her duty and responsibility, how could she ask something so selfish?

Entering the house, which Isao got for free, Amane looked around curiously, but Isao thought about returning to his original world. Previously, he thought that he would just visit this world for a short moment, but he didn't expect that something would drag him and that he would stay in this world for a few days. 

While Isao wanted to stay in this world a little longer since living during the Taisho period brought some novelties that he had never expected, he had decided to go back since, while he admitted that he was awesome, it didn't mean he was omnipotent, especially when he wanted to get the DNA of those professors on the famous university on the world of "Highschool of the Dead," as he wanted to build a business on this world. 

Frankly, due to the business acumen and investing talent he got from Yuriko Takagi, Isao had an idea of what kind of business he should create first, but it wouldn't hurt to go back first. 

So, without hesitation, Isao decided to return, and like before, everything within this world suddenly stopped, and a bright portal emerged, and soon, he returned to his original world. 

"...it's amazing." 

Everything was like a dream since nothing had changed. 

However, Isao knew that what was happening was real, especially when his hair was no longer covered in pomade and the memory, power, knowledge, and everything in the world of "Kimetsu no Yaiba" still existed on his body. 

"Let's go to Rei-senpai." 

Even though his mental strength was powerful and he knew that he had to work harder in this world, Isao decided to have a little comfort from Rei, take a day off, and decide to work hard tomorrow.
