Chapter 3. As a Good Brother
---
The structure of the ninja villages in Demon Slayer is quite similar to the ones in Naruto.
Multiple clans unite to form these villages, which have considerable autonomy in their management, while ultimate political power lies in the hands of the nation's ruler.
In Naruto, it's the Daimyo, and in Demon Slayer, it's the Emperor.
Ninjas act as mercenaries, though many show loyalty and obey the ruler's orders. This concept felt flimsy in Naruto, seeming like nothing more than poor logic, but that's not the case in Demon Slayer.
The absence of Chakra, Ninjutsu, and Bloodline Limits makes this structure far more realistic. After all, without these abilities, how are ninjas any different from normal people?
In Naruto, the difference between normal people and ninjas is so great that it's better to call them a different species.
And logically, they are a different species—or descendants of aliens.
But in Demon Slayer, the reality is different.
Ninjas are simply stronger-than-average humans, nothing remotely irreplaceable like those in Naruto.
Since ancient times, ninjas have worked in the shadows—essentially assassins for various clients, with the ruler being the biggest one.
But times change. And this time, humanity has gained its beloved weapon—the one that pulled the world from medieval to modern warfare: guns.
As always, technological advancement has taken jobs away from someone, and now it has fallen upon ninjas.
Who needs to hire ninjas when guns can do the job at lower cost and lower risk?
The crisis is real. Many ninja villages have gone bankrupt and disbanded, while others persist somehow, desperately searching for a way out.
And this ninja village, torturing children to create some kind of super ninja, is the prime example.
Now, not just boys but even girls are part of this brutal process. In this village, how could they not use all available resources? Hence, women are also trained.
While men follow a path leaning toward combat, women are trained more in espionage and childbearing. After all, the ability to get pregnant and produce children is considered quite important.
So, in another section of the village, opposite the boys' training grounds, the girls are molded into exceptional kunoichi.
After learning all of this, how could Kiyoshi stay calm? Everything he saw reminded him of Tengen's three wives.
What is the most iconic part of Uzui Tengen in Demon Slayer?
His looks? No!
His skills? No!
It's his three wives!
Now that Kiyoshi is here, how could he miss them? As for feeling guilty… why should he?
"I chose first, so there is nothing wrong with it. And I have a noble mission of carrying the banner of being human!"
So, Uzui Kiyoshi is quite shameless.
...
Though located in another part of the village, the training area isn't restricted. It's just that the twisted mindset of the villagers prevents them from coming here.
Women? What are they?
I need to train and become a ninja!
They have no concept of pleasure or anything like it. The tool theory—that ninjas must be emotionless and function as tools—is so deeply ingrained that the people here have lost the ability to even think or reflect.
If Kiyoshi didn't know about his previous life and the future plot, he too would have joined them and worked hard to become a ninja. Fortunately, he does know, and his priorities have changed.
Moreover, as a good brother, he can't let women distract Tengen from becoming a great ninja! So here he is, arriving early to pre-book the three wives and leave Tengen completely undisturbed in his quest to become the greatest ninja of all time.
And in this pre-booking, he's already secured one.
"Suma, you're indeed a good cook."
"Hehehe..."
Kiyoshi took the bento Suma prepared and ate with relish. He wasn't praising her out of formality—she really did make good food! At least far better than the disgusting meals served during training under the excuse of poison tolerance.
Damn it!
He couldn't help but shed some tears.
"Huh? Is it really that good?"
Suma couldn't help but doubt him. The bento was good, but not so good that someone should cry over it. Unfortunately, she didn't know the life Kiyoshi had been living so far.
Seeing her doubt, Kiyoshi set the bento down, grabbed Suma's hand, and pulled her into his arms.
"Ah?! Kiyoshi-sama? W-What is...?"
"What? Are you shy now?"
"Y-Yes."
Suma's face flushed red with shyness. Seeing her reaction, Kiyoshi's teasing smile widened, and he slowly blew air into her ear, making her moan.
"Hmmnnn... Kiyoshi-sama..."
"This is punishment for doubting me. If I said it was good, it was good. Understand? Or should I blow air again?"
"Y-Yes! This bento is indeed good!"
She quickly changed her answer. That air blow near her ear and Kiyoshi-sama's soft voice made her heart race and feel tingly underneath.
"Hahaha!"
Kiyoshi laughed, and his contagious laughter made Suma laugh as well. Putting aside his horny intentions, these interactions truly made him feel at peace.
All that pointed that in the end, humans are indeed social animals.
He tightened his hold and pulled Suma even closer, and she didn't resist, quietly accepting it. She was used to it—Kiyoshi often did this, and she liked it too.
"Suma, I will take you as my wife in the future. So don't hurt yourself during training and stay healthy. And make sure to eat and grow up. Understand?"
"Yes!"
