Inside the Night Raid Headquarters.
"The water dragon... turned into flames."
Tatsumi showed a shocked expression upon seeing this. This was clearly not the power of a Teigu, but the person's own power.
How is this possible? Can humans master such power?
"...As I thought." Najenda took a puff of her cigarette. She had indeed guessed correctly; this was not Teigu power, but the boy's own power.
However, it's a pity for such a talent not to join the Revolutionary Army when they possess such great power without a Teigu.
Looking at the clothes on him, he should be from a relatively backward village. Most of those places have been occupied by the Revolutionary Army. If they look carefully, they might be able to find him.
That's what Najenda thought.
Meanwhile, Esdeath, who was suppressing a rebellion in the north, looked at the screen and showed an interested smile. Although he was still a boy, his skills were extraordinary, and that power called 'Breathing'...
She was also very interested, so she decisively gave the order to send people to investigate this boy named Tanjiro.
In the Naruto World.
Team 7, who had finished their mission in the Land of Waves and were preparing to return to Konoha Village, were also stunned by this scene.
"Is this also a Ninjutsu?" Naruto Uzumaki had question marks popping up over his head. He didn't see the opponent making any hand seals at all.
Could it be the legendary hand-seal-less Ninjutsu? Or did the opponent quietly make seals where he couldn't see?
Impossible, the opponent definitely didn't make seals. But without seals, can one release such powerful Ninjutsu by relying on so-called 'Breathing'?
The scene of Tanjiro's first use of Sun Breathing led Naruto to mistakenly believe it was a powerful Ninjutsu.
...
Sasuke remained silent. He looked at Kakashi, hoping this legendary Copy Ninja would explain it to them.
As a Konoha Jonin, Kakashi must know many secrets.
Not just Sasuke, but Sakura Haruno was the same. She looked at Kakashi and asked, "Kakashi-sensei, what's going on?"
"Well."
Hatake Kakashi, holding [Make-Out Paradise], also showed a helpless expression.
Because he didn't know what was going on either. He was watching the video with his Sharingan active.
He could responsibly say that neither of the two boys in the video used Ninjutsu; they were fighting using a power he didn't know.
"Their fighting style is very similar to the Samurai from the Land of Iron."
Kakashi looked at Naruto, Sasuke, and Sakura and continued, "Perhaps this boy named Tanjiro is a genius from the Land of Iron. When I get back, I'll report this to Hokage-sama. Maybe we can get some information about him."
"However, Hokage-sama also frequently watches the multiverse projection. He probably already knows about this by now. The Anbu have likely been dispatched."
Hearing Kakashi-sensei say that, Naruto and the others nodded and said no more, refocusing their attention on the screen.

"My threads!"
Rui was shocked by this scene. He released countless blood-red silk threads, attacking Tanjiro.
Clearly, he didn't expect that the human who was just being one-sidedly beaten by him would suddenly explode with such terrifying power.
Those flames made Rui feel fear. The blood in his body was fearing this power.
The blood-red silk threads quickly rushed towards Tanjiro, bringing several wounds to his body.
But Tanjiro didn't even blink, as if this body didn't belong to him. He charged towards Rui with all his might.
'Don't stop! Keep running! If I stop now, the side effects of forcibly switching from Water Breathing to Hinokami Kagura will appear.'
'In that case, I probably won't be able to move for a while.'
'So! I must do it now! Run! I will protect Nezuko!!'
Tanjiro's inner thoughts were roared out through the video. This scene moved countless people.
And in the video, the Twelve Moons member who was being approached—Rui.
At this moment, he also felt a great deal of fear. He quickly retreated. This was the first time he had retreated, pushed back by a guy who wasn't a 'Hashira'.
Rui was retreating while throwing out blood-red silk threads, intending to stop Tanjiro.
But Tanjiro was not afraid at all. He swung the broken blade in his hand, and the flames cut through all the threads blocking him.
Outside the video.
"Go for it!! Tanjiro!!!!"
After finishing the medicine, Agatsuma Zenitsu roared at this scene, "Kill this guy who bullied Nezuko!!!"
"Oooooooh!!!!" Inosuke also let out a low growl. Although his throat was damaged and he couldn't make a very loud sound.
But now his fighting spirit had been ignited. He was fired up!! He couldn't wait to find a few demons to kill!!
Not just the two of them, but the other Hashira of the Demon Slayer Corps, seeing this scene, their evaluation of Tanjiro rose significantly.
This boy, in a sense, was already qualified to become a 'Hashira'.
Finally, in the video, Tanjiro approached Rui, and a white line appeared in his eyes.
'I see it! The Thread of Opening! I'm going to defeat him right here and now!'
'Even if we die together!!!'
Tanjiro swung the broken sword in his hand, while blood-red silk threads 'surrounded' him.
This scene was truly very dangerous. Tanjiro's broken sword was about to hit Rui, while Rui's blood-red silk threads had 'caught' Tanjiro.
Most of the beings watching this scene broke into a cold sweat for Tanjiro.
But there were still a few who hoped Tanjiro would die.
"Do you only have this much strength? Yoriichi, your successor is too weak."
Inside the Infinity Castle, Kokushibo looked at Tanjiro being pushed to this extent by a mere Lower Rank and felt particularly disappointed.
One must know that in the Sengoku era, that peak era when the Demon Slayer Corps could besiege Kibutsuji Muzan, no one had learned Sun Breathing.
Now, various Breathing Techniques are all modified from Sun Breathing, thus giving rise to other Breathing Techniques.
Sun Breathing could only be used by Tsugikuni Yoriichi.
Now that so many years have passed and Sun Breathing has appeared once again, its user is actually being pushed to a dead end by a Lower Rank.
This made Kokushibo very disappointed.
"Yes! That's right! Kill him!"
Still inside the Infinity Castle, Kibutsuji Muzan saw this scene, and his emotions fluctuated slightly. Although he knew Rui was already dead.
But that brat might have also died at Rui's hands. After all, according to the information, Rui was killed by the Demon Slayer Corps' 'Water Hashira', not by this brat.
In other words! Rui might have been heavily injured by this brat, but the brat who mastered Sun Breathing might have also been killed by him.
Just as Kibutsuji Muzan was shouting like that, the camera switched again.
This made Kibutsuji Muzan frown slightly. Every time the camera switched, nothing good ever happened!
