Ultimate Being from the Tokonosu City

If possible, Isao wished to have the power to make his women healthy when he had sex with them and also healed them when they were wounded. 

Unfortunately, while he had collected many DNAs, there was no one who had such a superpower, but even so, as a Hashira, one of the strongest Demon Slayers, Kanae wasn't weak. 

Even though it was her first time and she was constantly bullied by him, who had a lot of experience and knowledge of modern times, her body, which was strengthened due to the Demon Slayer training, could hold on for quite a while, enjoying the first sex she had with her loved one. 

Kanae knew that this might be wrong and might be frowned upon, but she didn't regret this, especially when she almost died. 

Watching how his semen flew out of her beautiful pink pussy, Kanae's exhausted face was full of smiles as she caressed her smooth belly. 

Still, Isao felt a little complicated, but if something really happened, then that's it; he didn't mind. Her appearance, with her long hair stuck on her sweaty, beautiful face, made him unable to hold his desire, and in this era, there was no condom. He might be able to pull out, but in the end, he decided to cum inside her. 

Due to this act, Isao knew that Kanae might get pregnant, but in the Taisho era, it was rare for a young woman of her age not to be pregnant with a child, so everything should be okay. 

However, was he ready to have children? 

If he were asked such a question, it would be hard to answer, and he could only answer it when the time came. Still, if possible, he wanted her to be pregnant. He knew that this was weird, and it wasn't like he wanted to have children, but somehow, he felt a certain revenge plot might happen. 

Yes, Isao didn't have a strong feeling toward the demons, and he even felt chill toward them. While Doma might have wished to kill him before, he had devoured Doma, and the rest was about to be devoured by him, too, so why should he have hatred or other strange emotions?

However, according to the usual plot, sooner or later, he felt like... he might receive a protagonist or second protagonist plot where his loved one passed away due to a demon. 

Kanae might tell him that she would follow him, but if the Demon Slayer Corps or the others asked for help, would she be able to refuse? 

By then, even if she had decided to elope with him, she might have decided to help the others and fight the demon. Moreover, the demon killed her parents, so there was no doubt her desire to eradicate the demon was stronger than anyone's. 

So, after all of that, what was the problem?

After all, Kanae was one of the Hashira, so fighting a normal demon was as easy as killing a chicken for her. 

Yet, according to the usual plot, she might meet the upper-rank demon, and then she would pass away. When that happened, Isao would have a reason to erase the demon and start his journey of revenge. 

Isao knew that his thoughts might seem like paranoia, but somehow, in this world, demons always targeted strong or talented people, especially those who didn't intend to fight a demon.

Whether it was the work of fate, the world, or Kagaya's plot, the best example would be Mist Hashira, Muichiro Tokito. 

In the story, due to Tokito's heritage as the descendant of a strong Demon Slayer, he was solicited by Kagaya and Amane to become a Demon Slayer. Naturally, his only family, his twin brother at that time, refused their solicitation since how could he allow his brother to work such a dangerous job? 

Being a Demon Slayer was nice, especially when they had a high salary, but the price of that salary was dead. 

There were many easier jobs in this country that allowed them to live a peaceful life, so why should they choose a dangerous job? 

However, unfortunately, even if they wanted to live a peaceful life, the world didn't allow them since a demon suddenly attacked them. 

When that happened, his brother died, he had amnesia, and he could only join the Demon Slayer Corps for revenge. 

So, why did a demon suddenly appear before them when their life had been peaceful before they met Kagaya and Amane? 

Sometimes, Isao felt like Kagaya plotted Tokito so that Tokito would become a Demon Slayer. He even suspected that Kanae or Shinobu might be in a similar situation since their parents were killed and they were about to die; Gyomei Himejima, Stone Hashira, came to save them. 

Was this all a coincidence? 

Or was it something created by the Demon Slayer Corps to get their loved one? 

Or was it how fate worked? 

Those who were strong in this world and had the potential to become the strong Demon Slayer would definitely have their loved ones, family, or friends killed by a demon. 

Even the creator of the first breathing technique, Yoriichi Tsugikuni, also wasn't immune to such a tragedy since he had his wife and newborn child killed by the demon. Even worse, the member of the Demon Slayer soon appeared. 

Everything was so suspicious, Isao thought. 

To avoid such a situation, he thought to impregnate Kanae, then she wouldn't work and focus on the birth of their children. He knew that this decision of his might seem absurd, and how could he impregnate someone whom he had just met a few days after he came to this world? 

Yet, if it was Kanae, Isao didn't mind making her pregnant. 

Their origins were quite similar, especially when they were all alone. 

Kanae could choose to stay with him even if she knew he didn't intend to join the Demon Slayer Corps and antagonize everyone, so why should he hesitate? 

Isao didn't feel that he had fallen in love with Kanae, but... she was just the right woman to become a mother of his children. 

Naturally, she wouldn't be the only one since, as a good guy, Kanae wasn't the only woman who was in need of help. There were many women who needed his help, so how could he abandon them?

Once again, Isao lamented at how good he was. 

"You are going to leave Tokyo tomorrow, right?" 

"Yeah." Isao nodded. "But you don't have to follow me. Stay here for a while." 

"Huh? Why? I want to follow you, too!" Kanae cried, thinking that Isao was going to leave her after all of this. 

"You're silly. Why should I you leave with me? I am as good as a pauper. I have nothing in my pocket now. How can I take care of you when I have nothing? Wait here and stay with your little sister since she definitely can't stay calm when you suddenly decide to leave. When I have settled down and made a place for both of us, and you have talked with your sister, I will bring you to live with me." 

Once again, Isao felt the horrible feeling of being in poverty. Fortunately, he had an experience of living a hard life in the world of "High School of the Dead." 

He started from zero and became one of the wealthiest guys in Tokonosu City before his wealth disappeared due to those "things." If it were others, they might commit suicide directly like those investors who lost their everything in stock market crashes. However, he was strong and had a system. Moreover, he wasn't the only one who lost everything, so it was all fine. 

Compared to his experience in that city, being poor during the Taisho period didn't scare him much since he had the ability to become wealthy soon. 

Once he had a place for the two, he would bring Kanae with him, especially when living in the city was much safer than living in the countryside like this.

Unlike in the countryside, where security hardly existed, in the city, there were so many people, and even if a demon was powerful, they wouldn't do anything that attracted the attention of the masses and government.

"It's fine. We can work together. I will stay with you even if you don't have anything," Kanae said softly and hugged his arm tightly. 

At the same time, watching how she was ready to work hard together even if he had nothing, he knew that he hadn't chosen the wrong woman. 

"....." 

Isao blinked his eyes and said, "Two weeks. Wait for two weeks, then come to see me." He knew that Kanae wouldn't give up, so he could only reassure her by telling her to wait two weeks before she came to live with him.

While Kanae didn't want to, she knew that she couldn't argue with him once again. She let out a helpless sigh and hugged him tightly. "I don't want to be parted from you." 

"Me too, but please understand me." 

"Hmm~!" Still, Kanae suddenly pushed him to the futon and straddled him like a female cowboy. "Then, let's do it again!" She definitely had to get pregnant tonight! 

While Isao was speechless, he didn't fear the challenge and welcomed it much.

The morning of the people in the past was early, and whether it was Isao or Kanae, they woke up at dawn. 

While Kanae helped him with the preparation for his journey to Tokyo, Isao washed his body with cold water from the well and was ready to leave for Tokyo to build his foundation in this world.

Still, he had to say the timeline was so inconvenient, especially when there wasn't even a shower or warm water, which made him helpless. 

His entire body was cold, but he didn't want to leave with a sticky body, so he could only bear to wash his body with cold water, washing his body on the outside.

Yes, there might be an indoor bath, but he might as well have tried this experience of living like people in the past since it was a rare chance, and frankly, it was troublesome to prepare hot water as one needed to burn wood. Nevertheless, he had to say that having a good woman was great since when he cleaned up his body, Kanae, who also had woken up, helped him prepare for his journey, even if her body was sore. 

When he thought such a good woman became his, he had to say that being a good guy was really great. It also made him become spirited, and he was ready to work hard in Tokyo, but when he walked toward his room, he knew that many had been staring at him, and as expected, one of the Hashira that stood by Kagaya's side yesterday, suddenly walked toward him and said, "Hey, fight me, coward!" 

"...." 

Isao was speechless and wondered whether he appeared like a pushover that one could threaten at any time. Still, he yawned and walked away. 

"Hey, where are you going?! I haven't done with my talk!" 

When the man was about to reach Isao, ready to teach Isao, his hand suddenly missed, feeling dumbfounded by how easily Isao dodged him, and even worse—

Slap!

The shock and pain quickly spread across his face as he didn't expect to be slapped by Isao. His head was dizzy, and his legs became weak since his jaw was also hit, but he forced himself to stand up with the support of the wall. 

After dodging with ease, Isao directly slapped the man's face cruelly, causing the man's mouth to be bloody, and one of his teeth flew out. 

[You have acquired the DNA of Tengen Uzui.]

[Do you want to absorb it?]

Naturally.

However, when everyone saw how easily Isao defeated Tengen, they were dumbfounded and ready to help Tengen.

"Ugh!"

Yet, unexpectedly, Isao suddenly kicked Tengan away toward all of them before walking toward the yard barefoot.

Before they could berate him, Isao suddenly said calmly, "Don't waste my time. All of you come." It might take a while for him to meet all of them, so before he left, he was going to get all of their knowledge, talents, experiences, and everything! 

"....." Everyone. 

This guy... veins popped on their foreheads, and they thought that they had to give him a lesson!

One versus all!
