Ultimate Being from the Tokonosu City

'No, no.' 

Isao quickly threw all of the bad thoughts away from his mind. He shouldn't think of something dirty in his mind, especially when he had decided to become a good person. 

While the definition of a good person in his dictionary was quite ambiguous, and some people even often misunderstood him, he had never done anything wrong after he had decided to become one. 

Isao had never done anything that would cause the death of others or even threatened others. 

Moreover, he had helped many people, and compared to others who used their everything for their own gain, he had never done so; he even joined the Demon Slayer Corps, a dangerous profession that might take his life away even though his future was great. 

Not only did he have a powerful body, beautiful women by his side, cute children in the future, and even an unlimited amount of wealth, yet even with such a future, instead of being afraid of death and enjoying his life in debauchery, he had decided to help the Demon Slayer Corps to destroy the demon from this world. 

If he wasn't a good guy, then what was he? 

As for the demon and Tanjiro? 

Isao thought it was time to meet them all and destroy them. Ah, he meant to destroy the demon, not Tanjiro. 

Still, the plot had changed as Tengen had died, so would Tanjiro have a happy family this time? 

Hopefully, since Isao had to admit that Tanjiro's life was quite pitiful. 

If there was something great about Tanjiro, it was the fact that he still had his little sister and sweet wife, Kanao Tsuyuri, who accompanied him until his death. 

While Isao thought of many strange things, Hinatsuru, Makio, and Suma hoped that Isao could help them to avenge their dead husband. Their husband had died, and they hoped for the Demon Slayer Corps to work together to avenge their dead husband, but Kagaya didn't wish to have a conflict with the demon until Isao came and joined. 

The power of the demon, especially the Upper Rank, couldn't be underestimated. Even the weakest Upper Rank could kill Tengen, one of the Hashira, so before Isao came, Kagaya decided to set up everyone to do training to become stronger. 

Everyone also agreed that their battle with the demon wouldn't be easy from now on, and they had to become stronger. Moreover, while they hated it, they knew that compared to Isao, they were all weak, so they waited for the good news that came from Kanae and Shinobu. 

However, Hinatsuru, Makio, and Suma didn't know that. No, they might understand that, but their emotions, the sadness and the anger that came from everyone's actions, and how weak they were. 

Yes, they were weak. 

If they weren't weak, then would they lick each other's wounds pitifully waiting for Isao? 

So, whether it was Hinatsuru, Makio, or Suma, they didn't wait for the Demon Slayer Corps and decided to visit Isao by following Kanae and Shinobu. They had to take this matter by themselves since it was their husband who had passed away. 

In this world, Isao was the only one who could avenge their husband and kill the demons who had killed their husband.

So, to achieve their ambitions, they would do anything! 

Even if—

"Sure." 

"...." 3x

"Huh?" 3x

The three poor widows lifted their heads and looked at Isao in surprise. 

"Um... what do you mean?" Hinatsuru asked with confusion. 

"As I said, yes. I am going to help you. Tell me anything about this demon, and I will kill it right away." 

As a good person, Isao decided to help three poor widows who had lost their husbands. As for asking for compensation, he knew that they didn't have anything, and the amount of their money was probably much less than his, who even had an industry and hundreds of people worked for him. 

If he asked for compensation, then wasn't he a bad person? 

Moreover, he had decided to join the Demon Slayer Corps, so this was a good thing to show his worth. If many were still in doubt that he had killed Doma, the Upper-Rank Second, when he killed the demon who had killed Tengen Uzui, then he was sure that no one could doubt him anymore. 

There was no need for him to explain; his strength and achievement told everything. 

"Wait! Wait! Are you sure? What you will fight is a powerful demon who can kill one of the Hashiras! This demon isn't some nobodies that you can kill easily! If you leave and die, what will happen to Nee-san and your children?!" 

The one who reacted strongly wasn't Kanae or Amane, who knew Isao decided to join the Demon Slayer Corps, but Shinobu, who knew nothing about his decision. 

Frankly, Shinobu had agreed to let her older sister be Isao's wife since she knew that he could take care of her. Moreover, he seemed quite well-behaved and devoted. When she thought her sister would have a happy life with him, she was glad, but suddenly, he told everyone that he was going to fight a powerful demon. What the hell was this guy thinking?!

Did this guy have a dead wish!?

Shinobu was enraged, and her expression was that of a demon. If Isao couldn't explain, then she was going to beat this guy up in her older sister's place! 

However, Shinobu's words caused a shock in Hinatsuru, Makio, and Suma. They knew how powerful the demon that had killed their husband was, and they knew the danger that came from their adversity. In the worst case, Isao might die. Yet, being blinded by their anger and vengeance, they ignored the consequences. 

If Isao died, then what would happen to Kanae and their future children?

They were wives, after all, and even if their husbands had passed away, they also often imagined what would happen to their future children when they or their husbands passed away. 

By then, what would happen to their children?

The three widows were unable to lift their heads, ashamed of their shameless request. 

"It'll be fine," Isao said. 

"It isn't fine! What if you die?!" Shinobu cried as she asked him loudly. 

Isao looked at Shinobu in silence and didn't expect that he held such an important place in her heart, yet this was normal. 

Shinobu had lost her family early, and it had always been hers and her older sister, along with Kanao, their adoptive older sister. By then, another member was added, and this person was Kanae's soon-to-be husband or her soon-to-be brother-in-law along with her niece or nephew, or even both if Kanae had given a twin. 

Shinobu treasured this family much, even if Isao was a bastard. 

However, Isao, who wasn't even a Demon Slayer, told her that he was going to fight a powerful demon. 

Don't be kidding me!

"It will be fine." 

Isao gave the same answer, but this time with a firmer tone. "Kanae and Amane-san knew about my decision to join the Demon Slayer Corps." 

"Nee-san...? Amane-sama...?" Shinobu looked at Kanae and Amane in surprise. 

"Believe him, Shinobu. He is stronger." 

"He won't die from those demons." 

Whether Kanae or Amane, they believed in Isao's strength, and as he had made his decision, as their women, they would support him with all of their rights. 

"They are okay, right?" 

Shinobu glared at Isao with tears when she heard such a relaxed answer. 

"Once again, it will be fine. I am strong." Isao patted Shinobu's head and said, "Moreover, I don't want Kanae to lose her little sister when we live happily here in Tokyo. You are going to be with us, and I will eradicate a demon for that."

"....." 

Shinobu couldn't say anything and just silently stared at him, but she knew if there was a reason why Isao decided to join the Demon Slayer Corps, then it was due to them since he didn't want them to live in such danger anymore. 

"I will follow you." 

"You are a burden." 

"Bastard!" 

Yet, Hinatsuru, Makio, and Suma, who had listened and watched him, swore that when they could get out alive from this fight, they would give their everything to Isao to repay for what he had done to them. 

Isao didn't know that, but if he knew...

Anyway, before the battle, Isao needed to make preparations. 

"By the way, Shinobu, show me your Insect Breathing." 

"...ha?"
