The Demon Slayer Corps' Future and Return to Konoha (4K)

The next day, night fell.

The Demon Slayer Corps headquarters has never been as bustling as it is now.

Every swordsman, every hidden swordsman, and every support and medical staff member like Kanzaki Aoi gathered together.

In the past, on nights like this, countless swordsmen would stay in various places, searching for traces of demons and fighting them.

Cheers!

The wine glasses clinked together in the center of the table.

Ubuyashiki Kagaya had a joyful smile on his face as he sat at a table with more than a dozen Pillars.

"You two are not yet adults, you can't drink!"

Kochō Shinobu snatched the wine glasses from the hands of the Tokito Brothers and stopped Meikyō from drinking.

"Ah, this..."

Meikyō and Tokito Brothers looked at each other in bewilderment.

It was only then that everyone at the table realized that these three were only teenagers, and still a long way from adulthood.

Especially Meikyō, whose terrifyingly powerful fighting ability always makes people subconsciously overlook his actual age.

"So, what should we drink?"

Tokito Muichiro asked blankly.

"Children should drink more milk to grow taller!"

Kochō Shinobu a laugh and pulled a large can of milk from under the table.

"Um... that's true, but Shinobu-neechan, when it comes to height..."

Meikyō looked down at Kochō Shinobu, who was holding a large jar of milk in her hands.

Now almost fourteen years old, he is nearly 1.6 meters tall, while Kochō Shinobu is petite, only 1.51 meters tall...

"If that's the case, then Kochō Shinobu should drink more milk. Besides, you're only a teenager, and you still have room to grow taller."

Tomioka Giyuu looked at Meikyō and Kochō Shinobu and said with a serious expression.

A tic-tac-toe symbol appeared on Kochō Shinobu's forehead.

"You, get out there and drink some milk too!"

Kochō Shinobu snatched the wine glass from Tomioka Giyuu, poured out the wine, and replaced it with milk.

"But I'm already twenty years old, I can drink alcohol, and at 1.76 meters tall, I don't need to drink milk like you, Kochō Shinobu."

Tomioka Giyuu is still seriously competing.

Kochō Shinobu's forehead.

"And Shinazugawa and Obanai, I've heard that drinking more milk is good for bones. Your broken ribs haven't healed yet, so I think you'd be even more suited to drinking milk."

As if he had just thought of something, Tomioka Giyuu spoke earnestly to Shinazugawa Sanemi and Iguro Obanai.

The lively atmosphere in the room suddenly turned cold.

Tomioka Giyuu's words always have this magical power.

Shinazugawa Sanemi paused mid-drink, his face darkening. He quickly exchanged glances with Iguro Obanai and Kochō Shinobu.

Seeing that the famous scene of the siege of the Giyu was about to be repeated, Ubuyashiki Kagaya had to step in to ease the tension.

"Putting height and milk aside for now, let's get back to the point. Now that Muzan Kibutsuji has been defeated, there are only a few weaker demons left in the world that Muzan Kibutsuji didn't summon to the Infinite Castle. I'm sure they'll be completely wiped out in the next few months. So, when there are no more demons in the world, what are your plans? Perhaps I can be of some help."

When Ubuyashiki Kagaya said this, many people in the room were immediately confused.

They mostly picked up Nichirin Blade in their teens and began fighting demons. Now that their long-held goal has been achieved, they are somewhat at a loss.

"I'll go first! After defeating Muzan Kibutsuji, I've already decided to go home and open a noodle shop, and add sakura mochi as a specialty dessert. Mr. Iguro is also planning to open a shop with me!"

Kanroji Mitsuri raised her hand, and with her excited movement, her exaggerated breasts, about the size of basketballs, bounced up and down.

"Opening a noodle shop? That's a great idea! I'll help Mitsuri and the others find the best location in Kyoto!"

Ubuyashiki Kagaya assured him with a smile.

"As for me, I actually read a lot of Professor Kitano's papers recently. I plan to go to the University of Tokyo to learn more advanced medical techniques from Professor Kitano, and then become a doctor to help save more people."

Kochō Shinobu rested her chin on her delicate white hand and said thoughtfully.

"To help more people? Miss Shinobu's thoughts are the same as mine! However, I don't have Miss Shinobu's superb medical skills, but fortunately, I'm in good health, so I plan to become a police station sheriff and help more people in my own way!"

Rengoku Kyojuro's face was beaming with a smile as bright as the sun.

Soon, everyone began to speak freely.

Uzui Tengen plans to use his glamorous appearance to become a movie actor, because not long ago, after importing foreign films, Japan planned to start preparing for its own film industry. Shinazugawa Sanemi, after struggling for a long time, realized that he only had swordsmanship as his specialty, so he planned to open a dojo to teach kendo. The Tokito Brothers other hand, had not decided what to do next. After experiencing so much, they could not possibly go back to their hometown to continue chopping wood.

Ubuyashiki Kagaya suggested that the two of them go to school to study, since their ages were just right. Himejima Gyomei planned to open an orphanage, adopt more children, and return to the rhythm of his life before he joined the Demon Slayer Corps.

As for Tomioka Giyuu...

"I haven't decided yet, but I feel like everyone likes me, so I shouldn't be disliked so easily. I think it should be easier to find a job later."

Tomioka Giyuu once again steered the conversation into silence.

"Mr. Giyu... I never expected you to have learned to joke around?"

Rengoku Kyojuro laughed and patted Tomioka Giyuu on the shoulder.

Everyone's eyes were filled with shock the moment they heard Tomioka Giyuu's words, while Tomioka Giyuu looked puzzled by everyone's reaction.

"I... I'm not joking."

"Mr. Giyu... has that been your belief all along?"

Kochō Shinobu's expression was filled with disbelief.

Tomioka Giyuu nodded earnestly.

Ubuyashiki Kagaya sighed inwardly.

If Giyu decides to do anything in the future, it's best to secretly help him out.

Then, Ubuyashiki Kagaya looked at Akira, who had been staring blankly and not saying Meikyō.

"And Meikyō, what about you?"

"Me..."

Meikyō has been thinking about what will happen in the world in the future, following the historical trajectory.

However, he has already received the blessing of Tsugikuni Yoriichi, which is the world consciousness. As long as he does not do anything to harm this world, he can almost enjoy the treatment of a Chosen One.

So, I should have the ability to prevent those things from happening, right?

"I don't think it's time for the Demon Slayer Corps to disband yet."

Meikyō made a startling statement.

"As a ninja, I think Uzui must also know that sometimes, some people are more terrifying than demons when it comes to harming this world."

Uzui Tengen recalled his experiences as a ninja and nodded silently, saying:

"Demons, because of their cruel and bloodthirsty nature and their habit of eating people, pose a great threat to this world. However, there are still beings like Lady Tamayo and Yushiro who are kinder than most people. In contrast, there are also many humans whose hearts are just as wicked as demons."

"Yes."

Meikyō picked up the milk and took a sip to moisten her throat.

That war, which brought tears to the world on this day, only ended a few years ago.

"The naval battle just a few years ago claimed tens of thousands of lives, which is far more destructive than any ghost."

"According to my estimates, perhaps in less than ten years, an unprecedented war will break out in this world, and the number of people who will lose their lives may be as high as tens of millions. In some years, an even larger war may break out."

Everyone was so shocked they were speechless.

Tens of millions of people?

How many people are there in this country?

Muzan Kibutsuji has lived for over a thousand years. Have there been ten million people who died because of him and those demons?

I'm afraid not.

"Meikyō, are you... sure?"

"Um."

Meikyō nodded solemnly.

"Therefore, I hope that the Demon Slayer Corps can continue to exist, using the power of the Oyakata clan as a springboard to influence this country as much as possible and prevent any possible war."

Ubuyashiki Kagaya remained silent for a long time before finally speaking:

"Will... tens of millions of people really die?"

"Yes, but it was in a very faraway country, but in the war that followed..."

"I see."

Ubuyashiki Kagaya stood up.

"The Demon Slayer Corps has shed blood for thousands of years in order to protect people from the destruction caused by demons and to prevent everyone from suffering the pain of losing loved ones. If war breaks out, more wives will lose their husbands, mothers will lose their sons, and children will lose their fathers. The Demon Slayer Corps must stop such things no matter what."

"If anyone intends to leave the Demon Slayer Corps and live their own life, the Oyakata clan will still do everything in our power to help you. And if any of you remain, then I would like to ask you all to join me in striving for the Demon Slayer Corps' second goal!"

Ubuyashiki Kagaya's voice lingered in the room for a long time.

"It seems that by staying with the Demon Slayer Corps, I can help even more people!"

Rengoku Kyojuro grinned.

"Hey, hey? We don't have to disband? That's great! We can continue to be together with everyone from now on!"

Kanroji Mitsuri jumped up excitedly again.

"This is truly... so touching. We can still stay together and, just like before, continue to strive for our noble goals!"

Himejima Gyomei welled up with tears again.

"Sigh, it seems that when I'm learning medicine from Mr. Kitazato in the future, I'll still have to take care of you troublesome kids."

Kochō Shinobu said this, but a gentle and beautiful smile appeared on her face once again.

In the darkness, Meikyō felt as if she had attracted some attention again, and looked up at the sky.

"I agree to your request."

Tsugikuni Yoriichi's familiar voice rang in Meikyō's ears once again.

The next moment, Meikyō could feel that the luck that had been supporting him was rapidly declining, until it reached a level only slightly higher than before.

"Thank you, Mr. Jiguo."

Meikyō secretly mouthed something to the sky.

A few days later.

When Kanzaki Aoi arrived at Meikyō's room to help clean, she found that the cleaning had already been done, but Meikyō was nowhere to be seen. There were only some letters left on the table with the ink still wet, so she quickly handed them to Ubuyashiki Kagaya.

" To Oyakata, it is as if we are meeting in person upon reading this letter. Please forgive me for omitting the pleasantries."

I'm leaving.

I plan to travel to a world beyond this country, to see it for myself, to explore it on foot, to meet different people and things, to learn more about different ideas and knowledge, and in order to find a way to achieve peace.

Perhaps we will meet again in the future, or perhaps we won't. But I know it will definitely take a long time. That's why I set off early. Or perhaps it's just a choice I made to avoid the sadness of parting.

If you receive these letters, please deliver them to each of your companions according to their names. I have spent an entire night writing down everything I want to say in the letters, so please be sure to pass them on.

I know this was a hasty and arbitrary decision, and I hope you will understand. Take good care of yourself and best wishes. I will not say more here. Respectfully yours, Uchiha Meikyō.

Ubuyashiki Kagaya stared at the letters in his hands, speechless for a long time.

The Ninja World, the Land of Fire, Konoha, the Uchiha Clan Compound.

In Meikyō's small house.

A blue light flashed, and the Meikyō reappeared in the bedroom.

The affairs of the Demon Slayer World have been largely resolved. In the future, Meikyō may occasionally return to visit his friends and observe which direction the history of that world will take.

But at least for now, it's time to turn most of our attention back to the Ninja World.

"I just don't know where my current strength ranks in the Ninja World, and what level I can reach after Awakening the Mangekyo."

Meikyō felt the slowly increasing pupil power in his eyes, and then glanced at the Demon Slayer Blade he had brought from the Demon Slayer World.

This sword was made by Tetsuchi Kawara, the village chief of the Swordsmith Village, using a forging technique that imitated the Ama-no-Ohabari Tetsuchikawahara Tetsu. Unfortunately, it did not incorporate Chakra Metal, so its Chakra conductivity is not very high.

Fortunately, it contains an extremely high amount of Scarlet Crimson Sand Iron.

This metal has a high compatibility with Natural Energy. If the Natural Energy and Chakra absorbed by the Meikyō use the Sun Breathing to condense into Senjutsu Chakra, then the conductivity of this Senjutsu Chakra in the Demon Slayer Blade is actually quite good, and it can also activate the solar energy within it.

However, while the Demon Slayer Blade is an absolute divine weapon against demons, in the Ninja World, the Ama-no-Ohabari, which has extremely high conductivity for Chakra and Senjutsu Chakra, is even more useful than the Demon Slayer Blade.

This was a slow and difficult piece of writing because I'm unsure if certain parts of it fall under sensitive topics.
