Marvel Mission System

Muzan then began creating demons to find the blue Spider Lily. It was for these reasons that the Ubuyashiki family formed the Demon Slayer Corps and began killing ghosts.

Members of the Demon Slayer Corps are separated into ten different ranks. From lowest to highest rank, these ranks are:

Mizunoto → Mizunoe → Kanoto → Kanoe → Tsuchinoto → Tsuchinoe → Hinoto → Hinoe → Kinoto → Kinoe.

To become eligible to join the Hashira, a Demon Slayer must successfully kill 50 demons or a member of the Twelve Kizuki as a Kinoe.

Once a Demon Slayer manages to join the Hashira, the words Demon Slayer will be engraved on their blade, symbolizing their position.

"Winters-kun, you have proven your ability to defeat one of the twelve kizuki. You can easily defeat him to the point of collapse, and you have also inherited the Sun Breathing style."

"If you join the Demon Slayer Corps, perhaps in our generation you can finally defeat Muzan Kibutsuji!"

Seeing that Kagaya was getting more and more excited, the other pillars seemed hesitant to speak.

"Ubuyashiki-sama, I can understand your humor and I admire your family's persistence and the sacrifices of each of the demon slayers."

Yuri felt that it would be better to explain some things clearly and in advance.

"However, I'm not in the habit of being someone's subordinate. To be honest, I hate taking orders."

"So, I'm sorry but, I'm not inclined to join the Demon Slayer Corps."

Despite wanting to help them, Yuri refuses to take orders.

He knows how cruel the fate of the male members of the Ubuyashiki family is.

But even though he doesn't like taking orders, he refuses not to help someone when they need it and he can help.

"So instead of asking me to be your subordinate, you should ask me for help."

Yuri said this very calmly, which immediately made all the pillars frown.

The rank promotions in the Demon Slayer Corps were all based on killing demons. In their opinion, it was very arrogant of Yuri to say something like that.

"I am not short of money and I have no desire to be in power."

"Then my conditions are simple."

"During this period, I only want the Ubuyashiki family to provide me with housing and the five basic breathing methods of water, thunder, fire, stone and wind."

"And I will look for the best opportunity for us to kill the twelve kizuki and Muzan himself."

"And lastly, I want the authority to decide on matters concerning the twelve Kizukis and Muzan himself."

After Yuri finished speaking, the air in the entire courtyard froze.

Just like the moment of tranquility before the storm, the pillars looked at Yuri with burning eyes.

Seeing this situation, Yuri couldn't help but shudder. Instead, he raised the corners of his mouth and said with a smile:

"I think the pillars must be very angry."

"But that doesn't matter. If you don't accept it, feel free to do something."

"If you can beat me, I will obey everything you tell me. But if you lose, you must fulfill what I said before, how about that?

All the pillars looked at Kagaya, wanting to get permission.

After pondering for a moment, Kagaya nodded.

Seeing him nod, all the pillars came into action almost at the same time.

Kanae, who had already seen Yuri's strength, didn't attack immediately, but hid behind everyone, waiting for an opportunity.

And because she thought that Yuri should already have the strength of at least pillar level, the rest of them were already angry and launched an attack immediately.

No one expected that, seeing this situation, Yuri would not retreat, but would approach, attacking the encirclement of the four.

"Shit boy!"

The Wind Pillar, Sanemi attacked first

This man has always had a foul mouth and an even worse temper. But despite this, he did not attack with his sword, but with his fists.

He felt that using his Sword could cause serious harm to Yuri, so he wrapped his fist with a blade created from the energy generated by his breath, hoping to teach Yuri a lesson.

[A/N: I don't think it's clear yet, but I've decided that breathing styles affect reality as if they were actually powers rather than just visual effects.]

If his attack hits Yuri, Sanemi is sure that Yuri won't be able to get out of bed for at least ten days.

At the same time, the Rock Pillar, Gyomei, who was the strongest among the pillars, seemed to have the same idea.

The ground in the courtyard seemed to shake as he ran towards Yuri.

Even one of the twelve Kizuki could end up seriously injured if hit by such an impact.

From the front, there is a rock pillar charging towards you, and on the other side, there is a wind blade curled into a fist coming towards you.

Seeing the strength of these attacks, Kanae, who was watching, felt that if she was the one on the receiving end of these attacks, she would be seriously injured.

Shinobu, who was the weakest outside the field, even unconsciously let out a soft scream seeing Yuri's situation.

But Yuri, who was at the center of this fight, couldn't help but smile.

"Very good..."

In the blink of an eye, Yuri opened the first door.

This first door is responsible for releasing brain limitations to reach 100% of physical capabilities.

Yuri didn't look at Gyomei who was coming towards him. He looked at Sanemi, clenched his right fist and attacked the man immediately.

His move shocked everyone. There were blades of wind wrapped around Sanemi's arms.

While the pillars were confused, a faint glow of golden light appeared between Yuri's arms.

This is exactly the solar energy produced by the Breath of the sun.

For Yuri, who has trained tirelessly in the use of chakra in the world of Naruto, this level of energy usage is very simple.

Under the incredulous eyes of all the pillars, the solar energy on Yuri's arm collided with the wind blade and then broke the wind blade.

As the two fists collided, the crisp sound of fractures resounded throughout the courtyard, followed by a burning smell.

Shinobu clearly saw Sanemi flying away, and the hand that punched him was slightly burned.

The most critical thing is that somehow this also interrupted his breathing style, causing him to fall to the ground.

With one punch, Sanemi was defeated!

At the same time, Gyomei was already approaching.

This rock pillar, which looked like a mountain, leaned forward with its left shoulder and collided with Yuri.

This level of physical strength is not something a human should be able to achieve. If anyone can match Gyomei, there is only one person in the entire Demon Slayer Corps, Yoriichi.

In this sense, Yuri didn't hide or avoid, he just took a step forward, turning sideways as if trying to knock down his opponent.

Shoulder to shoulder.

The two collided with such force.

BANG----!!!

The muffled sound echoed like a heavy object hitting the ground, and the air waves caused by the collision shook the flowers and plants in the courtyard.

Everything that happened was beyond everyone's expectations.

In this collision, the winner was not Gyomei, who was more than two meters tall, but Yuri.

The sound of bones breaking was quite subtle, but at this moment it was so distinct that it reached the ears of the pillars.

In an instant, everyone saw Gyomei flying like a cannonball. Only when he broke through a wall did he stop and fall to the ground.

Whether it was Sanemi who had just stood up with difficulty, Kanae and Shinobu outside, or Kagaya who was watching all this, everyone was in deep shock at this moment.

Gyomei is the strongest fighting force in the entire Demon Slayer Corps and also the most promising person to fight and win with Muzan.

The most famous and powerful thing about him is his physique that none of the mainstays can match.

But now, under the collision with Yuri, Gyomei revealed himself to be as fragile as a piece of paper!

"What kind of monster is this guy!?" Sanemi couldn't help but curse.

The other three people in the battle circle narrowed their eyes.

The two brief exchanges against Yuri were almost completed in an instant.

No one expected that the huge advantage of five against one would now be shattered with a punch and a collision.

But now the battle is imminent, and the only three people left are gritting their teeth at the same time and exerting all their strength in the only gap in the battle.

Rengoku, Tengen and Kanae wielded their swords without any qualms.

After all, the previous examples are right in front of you.

Instead of worrying about hurting Yuri, it's better to think about whether your sword skills might be better than theirs!

"Breath of Flames – Fourth Form: Esoteric Art!"

Rengoku shouted as he charged forward raising his blade backwards.

His attack was not as powerful as the aura enveloped in flames, but the thin light from the specially made dual swords swinging one after the other made the front yard suddenly light up.

At first, the swords looked like drizzle, but in the blink of an eye, they turned into an extremely violent storm.

Tengen's every attack exploded like a sonic boom. By wielding his dual swords, combined with the use of special explosives, he could exert tremendous power.

"Let's end this in an extravagant way!!" He shouted with a smile.

"Breath of Sound – Fourth Form: Endless Resonant Cuts!"

The thunderous blows and violent explosions of gunpowder resounded throughout the courtyard. Under the slashing fire, their dual swords that played a loud sound wave roared like explosions that could no longer be hidden!

Although all four of them acted one after another, and almost completed the coordinated attack between two in the blink of an eye.

On the other hand, Kanae, who was standing around, also suppressed her fear of a sudden sword attack like that night, and at this moment when she was most likely to win, she wielded all her energy into her sword.

Nine consecutive attacks were fired from all directions, stabbing at the same point. The trajectory was like flower petals. Even though it couldn't be compared to the previous two people's refinement, it was still a sword skill that couldn't be ignored.

The three's swordsmanship reached personal perfection, which finally made Yuri feel a little happy.

He firmly believed that if he wanted to become strong, he must not leave any obvious deficiencies.

The three most basic points of "mind", "body" and "skill" are indispensable.

Yuri already had the first two, but in terms of technique training, he was really immature.

This is also the reason why he became extremely greedy for Breath of the Sun and the other breathing styles. It's also the reason why he puts his precious roulette points into Tsukiyomi.

Seeing these exquisite sword skills, Yuri took the initiative to suppress his strength, drew his sword with great joy, and immediately swung his sword to block one by one.

He clearly swung the sword too late, but it was as if he was actively slashing at the three people's blades.

A series of swords collided, emitting a crisp metal clashing sound.

A fierce hum resounded throughout the courtyard once again.

As a result, everyone present saw a wonderful scene that they will never forget in their lives.

Under the all-out attacks of the three pillars,

Yuri resisted the blows from the three pillars using just an ordinary tachi.

The sword in Yuri's hands was getting faster and faster, and he began to use each of the Sun Breathing movements.

"Hahaha!" Yuri laughed as he countered each of the pillars' blows.

In an instant, a crimson light flew out, and with three clear sounds, the nichirin in the hands of the three pillars were cut in half.

The force of the attack caused the three people to stop. With only half of the knife's hilt in their hands, the three of them looked at Yuri, who was slowly sheathing his sword, in a daze, as if they had just woken up from a dream.

(End of chapter)

I intend to rewrite this chapter in the future, I believe it could have been much better.
