Offer a savior to the infinite world!

Demon Slayer Squad.

Hidden in history, it has existed for hundreds of years. It is a human organization that exists to exterminate evil creatures called "Demons". Using the "breathing method" that strengthens one's heart and lungs and corresponding sword skills, they fight against the cruel and ruthless demons and fight to protect humans under the sun. This is the Demon Slayer Corps.

What are ghosts? They are monsters that are transformed from humans, immortal and feed on humans. They are transformed by the blood of the legendary ghost king Muzan Kibutsuji, and have completely thrown away the moral principles and conscience of their human lives. They only fight to eat people, kill and eat. It can be said that they are demons that are meaningless to the development of social civilization and only bring disaster to the world.

Tanjiro Kamado, the boy whom Lin Yi met during the first rescue mission, almost all of his family members died in the attack of demons, and his only sister Nezuko was also transformed into a demon, almost killing Tanjiro. Although he later regained some sanity, his way of thinking degenerated and became like a child. He usually relied on sleeping to resist the appetite of demons, and gradually became stronger in this way. Well, although it sounds a bit strange, Tanjiro's sister Nezuko does seem to be able to gradually become stronger by sleeping.

In short, Tanjiro joined the Demon Slayer Corps, learned the Water Breathing and related sword skills, mastered the Full Concentration Breathing Method, and accidentally discovered that the Fire God Dance Kagura inherited from his family could be used as an extremely powerful sword breathing method. After multiple rescue missions, he broke through himself in the death battle and possessed the magical power called the stripes. Now he can be said to be very confident, and he is happy from the bottom of his heart that he can fight against more powerful demons and better protect others.

I will definitely find a way to turn my sister back into a human.

Moreover, Muzan Kibutsuji, the ultimate source of countless tragedies, I will definitely defeat him!

Tanjiro, who firmly believed in this, finally received a new ghost hunting mission during his training after several rescue missions.

Go to the Infinite Train and, under the leadership of the Flame Pillar, investigate the disappearance of more than 40 people on the Infinite Train.

Flame Pillar.

Purgatory Anjuro.

One of the nine pillars of the Demon Slayer Corps, a top combat member who truly represents the human side.

A cheerful young man who loves to laugh and always has a loud voice. He uses the breath of fire and its corresponding sword skills. He is the leader of Tanjiro and his two partners, Zenitsu and Inosuke, and is the main person in charge of this mission.

The so-called infinite train is actually just a coal-burning train. For the era when Lin Yi lived, it was a very backward thing. But in the era when Tanjiro lived, it was a serious new thing, an advanced technological creation that they could hardly imagine. Because of this incident, the reckless and impulsive Inosuke even regarded the train as some kind of large monster, and shouted and rammed into the carriage to decide the outcome.

This kind of funny and humorous behavior can be regarded as a routine in the daily life of the three people, and it is quite good as a diversion.

The subsequent ghost hunting mission, although not extremely dangerous, was also very thrilling. Because they encountered one of the twelve demons, the demon ranked as the first of the lower moons. The other party merged his body with the entire train, so that the flesh and blood of people kept appearing in the carriage. And this demon also has the terrible power to pull people into the illusion. If you want to break free, you can only commit suicide in the illusion.

In order to destroy the evil ghost, Tanjiro and Inosuke worked together to successfully find the other party's neck at the front of the train, which represented the ghost, and cut it off, ending the ghost's mischief. When the ghost was destroyed and the train merged with it began to lose control, Rengoku Kyojuro used the Breath of Fire continuously in the train and successfully stabilized the train, making the whole train achieve a miracle of zero casualties after it overturned.

At this point, the story comes to a successful conclusion, and a ghost hunting mission has reached the most perfect ending.

That would be nice if that were the case.

If that were really all there was to it, that would be great.

[The God of Fire Kagura: The Burning Sun Red Mirror! ]

His breathing suddenly deepened, and the marks on his forehead appeared like burning flames, while the Sun Blade was swung forward with incomparable ferocity.

But, it missed.

Nothing could be hit.

The opponent simply turned his head slightly and easily avoided Tanjiro's full-strength attack.

"Ha, that move just now is quite interesting. Although you are not as good as the pillars now, your talent for growth is definitely not bad. Why don't you also become a demon, Tanjiro?"

The man with a grin, pale skin, short pink hair and eyebrows, and dark blue tattoos all over his body looked at the boy, stretched out his hand expectantly and said.

"That's -- impossible!"

With an extremely resolute answer, the boy thrust his blade forward fiercely.

[The God of Fire Kagura·Yokato! 】

The ferocious sword skills with shocking momentum fiercely stabbed at the enemy in front.

when!

However, he just extended his fist and the attack was easily deflected. Incomprehensibly, the enemy found the subtle key point of the knife swing and easily neutralized the powerful attack on the spot with just one strike.

You can see that the other person's other hand has been clenched into a fist and is about to swing over.

Get out of the way!

You must get out of the way!

He clearly saw the enemy's fist approaching him.

However, my body couldn't react in time. No matter how hard I tried, I couldn't respond in time.

If this continues, I will...

"That's right, as human beings, we will never transform into ghosts!"

The mighty sound, accompanied by the sudden downward chopping of the Sun Blade, left a fiery mark at this moment.

[Breathing of Flame: Form Three: Thousands of Feet of Flame! ]

To chop and cut off.

The man's arm, which was about to hit Tanjiro, flew into the air, and the raging flames quickly changed direction, about to chop the man's neck. However, the opponent quickly retreated and dodged, and within less than a breath, he had opened up a distance of more than ten meters.

"Yes, it's really good. The blazing flames and the fire that has just started to burn, you are all people who can become the strongest warriors."

With a chuckle, the man's severed arm had grown back and returned to normal.

"You guys, if you don't become ghosts, wouldn't it be a pity, Kyojuro, Tanjiro?"

"As long as you become a ghost, you will have unlimited time to practice and become stronger."

"As long as I can become a ghost, I no longer need to worry about the fragility of my body. I won't get old or weak. For those who want to become stronger, isn't this a great thing?"

Amidst the faint laughter, the man's expression showed a bit of intoxication, and the words in his pupils seemed to become brighter.

【Winding】

【Three】

These are different words located in the man's left and right eyes.

And this represents the identity of this man.

ghost.

The Twelve Demon Moons under the most powerful demon king Muzan Kibutsuji represent the third demon of the Upper Six, and can be understood as the fourth most powerful demon in the world. Above it, only the Upper Six One and Two and Muzan himself are stronger than it. Apart from them, whether demons or humans, they are all weak.

"Once again, I sincerely invite you to become a demon, a demon that can become infinitely stronger, and then fight with me and Akaza forever."

Extending his hand, the man smiled and spoke to the two of them once again.

"That's impossible. I'll say it again, I will never become a ghost!"

The young man answered loudly. His name was Rengoku Kyojuro. He clenched the flaming Nichirin sword in his hand, pointed it at the man in front of him and said.

"I will not accept your invitation, Akaza. I became strong in order to protect. I will not actively hurt anyone just to become strong."

Tanjiro took a deep breath and answered with the same seriousness.

It is naturally impossible for them to accept each other and coexist. This is the case between humans and ghosts.

So all we can do next is to fight and decide whether we live or die, that's all.

Can you win?

The opponent is the Upper Three, a terrifying evil spirit that has not been replaced for a hundred years and is much more powerful than humans.

can win!

You will definitely win!

I have become stronger, much stronger than before. And Mr. Rengoku is a pillar, one of the nine strongest members of the Demon Slayer Corps. We will definitely win this battle, even if the opponent is an upper-rank demon!!!

When the boy was thinking this, he saw the man in front of him with the corners of his mouth slightly curved.

"If you refuse to become a ghost, I will kill you."

He stretched out his hand and bent his body slightly.

The curve of the man's mouth turned ferocious the next moment.

"Before you die, I will be a little more serious, so that I can feel your limits and remember your strength."

[Destruction Kill·Lord Needle Technique is launched! ]

Traces like snowflakes spread out on the ground, and then, when the evil spirit named Akaza really took action, Tanjiro felt firsthand what real chill was.

【Destruction Killing Random Style! 】

The fist hit out violently, and in the next moment, it exploded with an extremely terrifying force. Although he had swung his sword to block it, Tanjiro was still thrown out directly, and retreated more than ten meters before he could stabilize his body.

"Stay away, don't come near!"

The next moment, Rengoku Kyojuro's voice reminded the young man loudly, and he immediately started fighting with the evil spirit. The flaming Nichirin sword swung out patterns of flames, and collided with Akaza's fist with a green afterimage again and again.

Now, I can’t even block an attack from that ghost?

Take a deep breath and take another step forward.

The fire element, which served as the system's assistant, emerged silently, fell on Tanjiro's blade, and immediately ignited a raging fire.

The color of this flame seems to be different from normal flames. That is the result of the adjustments made by Tanjiro's system assistant over the past period of time. It can simulate the strange power of the sunlight in this world to a certain extent, which the sun in other worlds does not have. It can make the target hit by Tanjiro's sword be cut open, and the parts of the body that touch the flames will suffer damage equivalent to sunlight. This move can kill some weak demons without even cutting off their heads, and when facing the demons of the Lower Rank One, it can also greatly reduce their regeneration ability.

If the goal is the upper string, I haven't tried it yet, but it must be possible!

[The God of Fire Kagura——]

"Wow, what is this? I sense a great deal of danger from the flame on your knife."

Akaza's voice suddenly appeared beside the boy the next moment.

when? !

He was clearly fighting against Mr. Purgatory just a second ago, why——

[Breathing of Flame - Type 5 Flame Tiger! ]

The figure of Rengoku Kyojuro rushed over with a loud sound like a tiger's roar, and stabbed Akaza beside Tanjiro.

【Destruction Killing·Extermination Style! 】

Akaza performed his moves almost at the same time, no, earlier than Rengoku Kyojuro, and faced the opponent's attack straight away.

Taking a deep breath, his body tensed, the lines on his forehead seemed to become hot at this moment. Tanjiro twisted his body forcefully, and in the next moment, he turned around and swung out with a burst of power.

boom!

Under the violent collision of force, the ground was torn apart, and the earth and rocks flew all over the sky. The young man was sent flying backwards, and the Sun Wheel Sword in his hand broke directly.

Unable to block the attack, there is no way to even slightly neutralize it.

Tanjiro could even clearly feel that the bones in his right arm had been broken by the head-on attack just now.

But, I created my own opportunity.

In his bloodstained eyes, the boy could clearly see that Akaza's arm that attacked him had been burned to ashes by the flames, and even half of his shoulder was gone. This was the powerful force brought by the sunlight, which the ghosts could not resist. Therefore, with the limb resurrection ability temporarily unavailable, the ghost with only one hand left would definitely not be able to withstand Mr. Purgatory's attack.

"Mr. Purgatory!"

The boy who was coughing up blood shouted.

"Thank you for the opportunity, Kamado-kun. I will take the head—"

[Breathing of Flame - Mystery Nine Form - Purgatory]

The momentum that burst out in an instant, even ordinary people who have not received any training can feel the man's temperament burning like fire at this moment.

The light burst out at this moment with great brightness, and rushed towards the evil ghost in front with a resolute momentum, aiming at the opponent's neck.

This attack must win!

With this thought in mind, the man swung the flaming blade in his hand.

Akaza, who was in the front and whose arm could not regenerate immediately, looked at Rengoku Kyojuro who was swinging his sword at him with an expression of great surprise, and spoke softly.

【Destruction Kill·Final Style】

The air stagnated the next moment.

Then, countless blue flashes floated up and gathered straight towards Rengoku Kyojuro who was swooping down towards him.

【Blue and silver chaotic residual light!!!】

The next moment, the blood that was torn apart made the boy's eyes freeze.

That... that's...

No...how could it be...how could it be...
