"I'll handle this guy."
Tanjiro, Tamayo, and the others looked up and saw a man with a missing arm standing on a large tree. His shoulder-length hair was tied up, and his eyes emitted an eerie red light.
In Nagi's hand lay a severed head—the head of a girl named Kagome. Her eyes were wide open, and a radiant smile remained on her face even in death…
What made Tanjiro uneasy was that the other person smelled extremely evil and had a chilling, winter-like quality, but they were not a demon.
"You, you're human??" Tanjiro asked, puzzled.
"That's Mr. Uchiha, Lord Tamayo's patient from a couple of days ago," said Yushiro from the back room.
Humans?
Uchiha Nagi jumped down from the tree, gently laid Kagome down, and wiped the blood off Kagome's face.
The girl, whom he had only known for a few days... then stood up and walked slowly toward the male ghost, Yahaba, with a blank expression.
"You shouldn't have hurt her, she's innocent."
As she said this, Uchiha Nagi's cold eyes were as frigid as winter, yet a raging fire lurked deep within them.
Looking at the red-eyed man in front of him, the male demon Yahaha was not afraid but delighted: "Rare blood, and the best of rare blood, haha, you're mine now."
"Hey, Yahaba, don't even think about taking it all for yourself. We'll split it in half." The female ghost, Shusa-maru, immediately said from the side.
"Okay, okay~" Before Yahaha could finish speaking, Uchiha Nagi in front of her had already started fighting.
"Fire Release: Great Fireball Technique".
Seven or eight fireballs, each two meters in size, flew towards the male demon, Yahaba. Yahaba was shocked. Hadn't the Demon Slayer Corps only ever used breathing techniques and sword skills? When did they acquire skills similar to their Blood Demon Art?
Yahaha nimbly dodged several fireballs and used his Blood Demon Art to disperse a few more. However, when he jumped onto a tree, he found that several shurikens were already flying towards him.
Looking at the shuriken that he couldn't aim at, he said with disdain, "Hmph, you can't even hit a person, and you still..."
However, before he could finish speaking, the shurikens wrapped around him and the tree in the next second.
"This is... a black steel wire?" Yahaba exclaimed in surprise.
Using the darkness as cover, the shurikens exploited his blind spots, colliding with each other to bind him tightly. But if that's all...
"Fire Release: Dragon Fire Technique." A long flame rapidly extended along the steel wire of the shuriken, striking the Oni-man Yahaha before he could break free.
The enormous flames illuminated the night sky; their intense heat could melt even steel.
He was killed just like that? Tanjiro stared blankly, then suddenly realized what was happening and shouted at Uchiha Nagi.
"Be careful, he's not dead yet. Demons can't be killed unless their necks are severed by a Nichirin Blade. Be careful."
Immediately, a figure rushed out from the flames, waved both hands towards Uchiha Nagi, and an invisible psychic force attacked Uchiha Nagi.
"Damn it." Tanjiro swung his Nichirin Blade, trying to run over and cut off the invisible red arrow, but the female demon Suzamaru blocked his way.
"Haha, you should worry about yourself first, kid." Then, the female ghost, Suzamaru, threw several powerful balls at Tanjiro.
"Damn it, watch out!" Tanjiro had no choice but to interrupt the rescue and directly fight the female demon, Suzamaru.
Unexpectedly, the invisible red psychic energy was easily dodged by him just as it was about to strike Uchiha Nagi.
"What? He can see?"
"How is that possible? How could a human see it and then hide from it?" Oni-man Yahaba said angrily, refusing to believe it.
However, in Uchiha Nagi's eyes, the thing that resembled psychic power appeared clearly in his Sharingan. Although it wasn't chakra, it was made of energy, and he could see it very clearly.
Not only that, due to Kagome's death, cold and evil chakra began to mutate and surge into her right eye, and Nagi Uchiha also became aware of the abilities within her right eye's Mangekyou Sharingan.
"Shadow Clone Technique~" Uchiha Nagi formed a hand seal, creating five identical clones, which then ran towards the demon man Yahaba.
"What is this? Blood Demon Art? How come there are five people?" Oni-man Yaha was dumbfounded again. There was one Upper Moon demon who could create clones, but he had never heard of a human who didn't know Blood Demon Art being able to do it.
The demon man, Yahaba, swung his hands rapidly, grabbing two of his clones and quickly lifting them into the air before slamming them down.
*Snap*
The two clones turned into two wisps of smoke. Then, the demon man Yahaha looked at the remaining three, who were already rapidly approaching him. However, he was not flustered. Without a Nichirin Blade, one cannot kill a demon.
"Hahaha, without a Nichirin Blade, you want to burn me to death? Demons can't be burned to death, only you fragile humans can be burned to death."
Uchiha Nagi raised one hand above her head expressionlessly and said, "You're too confident, Solar Flare."
A blinding light appeared in the darkness, turning the night into day. Even Tanjiro and the female demon Suzamaru, who were fighting nearby, were blinded and had to stop fighting for a moment.
"Besides, who says flames can't burn you to death, Amaterasu~"
Uchiha Nagi opened her right eye, blood flowing from the corner of her eye, and a black flame struck the demon man Yahaba directly.
"Ah, my eyes! Flames again! I told you, flames can't kill me! Wait, what kind of flames are these?!"
"Ahhh~ what's going on?"
The Oni-man Yahaba's regenerative abilities were clearly superior to those of humans; what took humans ten seconds to regain their vision, he recovered in three or four seconds. However, after regaining his sight, Yahaba discovered that his entire body was covered in black flames, and what was even more terrifying was that these flames could not be extinguished; no matter how he tried to put them out, they would continue to burn.
Uchiha Nagi looked on expressionlessly. "I'm curious, is your regenerative ability truly without energy limitations? Enjoy it."
"Damn it~ Ahhhhh..." Oni-man Yahaha opened his arms, but the intense burning of the black flames and the strange energy within them interfered with his Blood Demon Art.
His skin, flesh, and bones were constantly scorched to ash by black flames, but his demonic constitution allowed him to regenerate rapidly. This pain was like being torn apart by a thousand knives, causing him unbearable agony.
Becoming a demon doesn't mean you can't feel pain...
"Amaterasu will not go out until the object being burned is reduced to ashes, unless its master makes it go out."
"It's your turn." Uchiha Nagi looked terrifying; her three tomoe were fused together, forming a plum blossom-shaped Mangekyou Sharingan, and blood was still flowing from her right eye.
"Damn it~ You can defeat a demon without using a Nichirin Blade? Are you even human?" The female demon, Suzamaru, was so shocked that she forgot to attack Tanjiro.
Amaterasu is Itachi's technique, but it was used by Nagi Uchiha at this moment.
That's because Nagi Uchiha's right eye's Mangekyou Sharingan ability is copying. She developed this ability because of her extreme desire for power.
To be precise, the ability is to [see through and analyze the patterns in how things work].
He can analyze and see through any ninjutsu after seeing it only once. As for whether he can copy it, it depends on a combination of factors.
For example, Kimimaro's Shikotsumyaku and the First Hokage's Wood Release are techniques that require bloodline limits. He can copy them, but he can't use them unless he also has the same genes.
And this demon in front of him, his Blood Demon Art, that invisible telekinetic power, Uchiha Nagi also saw through and copied it, but he doesn't have the demon's genes and can't use it, unless he can modify it into a technique that can be used without the demon's genes.
However, this is enough.
In the world of Naruto, how many powerful techniques are there? Rasengan, Chidori, Flying Thunder God Technique, Edo Tensei.
There's also the Raikage's Lightning Release Armor and the Tsuchikage's Dust Release.
Here, you'll find breathing techniques of various attributes passed down through generations for thousands of years—
