"Iinuma-sama, your weapons are finished!"
"Finally!"
After spending their time at the mountain resort (Swordsmith Village) for a while, finally, the weapons that Isao had been waiting for were completed by many masters of the blacksmith in this village. Naturally, they were also forged from the purest Scarlet Crimson Iron Sand and Scarlet Ore, which were found on high mountains like the Sunlight Mountain, which was perpetually bathed in sunlight all throughout the year on Mount Yoko.
Still, hearing that Hinatsuru, Makio, and Suma felt slightly at a loss since the three felt their trip was so wonderful. It was like the best dream, and they didn't want to wake up. On this trip, Isao had fully conquered them, whether it was their hearts or bodies. Their bodies had already been rewritten, and their bodies had been shaped into his.
Every part of their bodies had become so good that they sometimes forgot their previous husband.
Yet, they couldn't be blamed since Isao was too fierce, and he discovered their weakness easily, making them unable to fight back and only succumbing under him, which they were happy for.
Rubbing their bellies, they knew that they had become pregnant, especially with the amount of semen he had ejected inside her.
Still, if Isao knew what they thought, he would definitely try to make a condom as soon as possible since the protection in this era was quite hard, and it was so easy for a woman to get pregnant.
After all, even though he had pulled out when he came, a small amount of semen would leak from the precum whenever they had sex, and naturally, they would get pregnant.
This also made him realize the importance of training his demon ability so it would make him safe and okay whenever he had sex without protection.
This was also the reason why he had never touched Kanroji since he wasn't sure whether she was ready to get pregnant or not. Moreover, with how pure she was, he couldn't bear to attack her somehow.
Still, more importantly, he had to get his weapons first.
Two weapons.
One was a saber and a one-handed poleaxe.
Yup, those were his weapons.
It might be a strange choice of weapons, but Isao thought that those two were the best weapons for his fighting style.
When he fought with Daki, Gyatoro, and Akaza before, he thought that fighting with two weapons was more comfortable and easier for him, but a katana and a rapier-like blade weren't that suitable for him, especially a rapier as it was too fragile for his liking.
Moreover, using poison was too troublesome and time-consuming.
So, with all of those factors, he decided that those two weapons were his two weapons.
He had a saber in his left hand and a one-handed poleaxe in his right hand.
Naturally, the choice of his weapons surprised everyone, and they all looked at the weapons curiously.
A saber was quite similar to a katana, as it had a slight curve on its blade, but naturally, it was different. It was shorter and crafted for a one-handed grip. Moreover, it was a weapon that focused on swift attacks and offered increased mobility.
On the other hand, a katana was designed with an extended, two-handed grip that delivered exceptional command and leverage, facilitating potent slash movements.
As for which one was better, it depended on the individual, but as he used two swords, a saber was better for his liking.
Still, compared to a saber, which was a sword, his choice of a poleaxe surprised everyone as it was a strange weapon that was hardly used by the people in this country.
Or rather, poleaxe originated from the West.
However, one could tell how dangerous this weapon was as it was the combination of an axe, a spear, and a hammer into one. The head of this weapon was a combination of those three weapons.
In other words, he could chop, stab, and smash his opponent with just a single weapon.
Amazing, right?
Naturally, his weapons were quite unique, especially the handle part, as there was a small gap, like a small handle, at the tip of the handle of those two weapons. Others might think those two parts were meaningless, but that wasn't the case, especially due to his new technique, which grabbed his weapons with the gap between his index and middle fingers, extending the range of his weapon.
A small handle at the tip of the handle of his weapon was intended to be used to grip in such a special way.
Holding his two weapons, Isao then came to the battle area where the Demon Slayer could hone their combat skills with many mechanical training dolls. Naturally, he had gained the DNA of those blacksmiths who crafted those mechanical training dolls, as those training dolls were quite interesting.
Still, he didn't have an interest in a normal training doll, so he directly came to the strongest doll in this "Swordsmith Village."
Yoriichi Type Zero.
It was a mechanical doll created in the Sengoku Period to mimic the strongest Demon Slayer, Yoriichi Tsugikuni.
Was it possible?
Probably, but Isao could see that they had worked so hard that they even gave this doll six arms as Yoriichi was too fast, and six arms were the only way for this mechanical doll to mimic Yoriichi's movement.
When Isao spoke of his intent, everyone quickly came to watch the fun and see how strong Isao was.
If it was in the past, they didn't think that Isao could defeat this mechanical doll, but now, it was different as this doll's quality had eroded for hundreds of years from its creation.
"I wonder whether he can defeat it..."
"He should be, but then again, it might be a tough battle."
Yes, no one doubted that Isao could defeat this Yoriichi Type Zero, but they knew that it would be a tough battle, and he might need to spend a day defeating him.
"IInuma-sama, Yoriichi Type Zero, has 108 different movements based on the legendary Demon Slayer, Yoriichi Tsugikuni. Its power surpasses most humans and has even defeated many of those powerful Hashira in history. While it is true that it has become far weaker than the original, it is still a strong opponent. Are you sure that you are going to face it?"
"If I destroy it, it is okay, right?"
"..."
"Hahaha..."
Everyone then started to laugh when they heard Isao's question.
"Sure, sure. If you can destroy it."
No one thought that Isao could destroy this mechanical doll, especially when it had been tuned to take advantage of Isao's weakness.
Well, Isao didn't have a weakness to begin with, so it was hard to say.
However, no one thought that Isao could destroy this doll since this doll was that powerful, and this doll also crystallized their knowledge for the past millennium.
Yet, hearing the laugh of the blacksmiths, the four women frowned, but they didn't say anything since they believed in Isao.
Regardless, the duel between Isao and Yoriichi Type Zero started.
The two stood in one place, and neither made a move.
Isao raised his brows, feeling bored, so he approached this mechanical doll; at that moment, the Yoriichi Type Zero started to move, moving all the blades on its hands, ready to slay down Isao, but—
At that moment, the two weapons in Isao's hands changed their colors.
The weapon's original color turned into blood red-violet with a dark shade that appeared so ominous, as if cursed and poisonous. Yet even if the blades might appear vile, they were beautiful, alluring, and captivating, making them unable to look away as if being bewitched.
Only—
CRASH!
The loud sound that came from the destruction stunned everyone.
Using the hammer part of his poleaxe, Isao smashed this mechanical doll into pieces.
"..."
Sighing, he felt a bit disappointed at how weak this doll was but thanked everyone regardless and was also grateful that he had asked beforehand, so there was no need to take responsibility for this doll. "Thank you for your care and these weapons. We'll go back now."
"Ah, oh."
"..."
The voices that came out of their mouths were utterly pitiful, and they couldn't look straight at him, only looking away in fear as they gulped.
"Goodbye."
The four women also bowed their heads before they quickly followed Isao, leaving with a smile and happy with his new weapons, but others were still unable to believe what was happening.
The ultimate power didn't come from a powerful slash that divided something into two or many times or fancy techniques that mesmerized people with their beauty but from an overwhelming strength that destroyed everything into smithereens.
This was what Isao had taught them.
Yet, what kind of a human had the power to smash such a durable thing into pieces?
However, everyone knew that the destruction of the Demon King, Muzan Kibutsuji, was near.
Still, when Isao left with his women, few people cried as the Yoriichi Type Zero was destroyed into pieces, but that was a small matter compared to the end of the demon.
"Where should we go now, Isao-sama?"
Everyone was curious, but Isao's destination was clear.
"There is a village that I want to visit. Let's go there first."
"Hmm?"
At the same time, a boy with a flame-like mark on his forehead looked at his family with a gentle smile and said, "Mom, I will go first!"
"Yeah, be careful, okay, Tanjiro?"
Tanjiro Kamado looked at his mother with a gentle smile, but his eyes showed exhaustion. Still, his family was by his side, so no matter how tough it was, he had to work hard.
Only the wheel of fate had started to move, and his family was targeted by something vile.
Ah, that vile thing wasn't Isao, okay?
Once again, Isao was a good guy!

Thanks for the list!
