"I don't mean to mock you, I'm just genuinely curious, what kind of creature are you?"
Seiichi had to maintain his act, showing the surprise of seeing a demon for the first time. Of course, it really was his first time seeing a demon, and unexpectedly, he was surprised by the terrible smell coming from the demon.
Good thing I didn't choose the Demon King's body, otherwise wouldn't I be this smelly myself?
"Another Demon Slayer? No, that's not right, are you a normal human?"
Daki eyed the person standing on the opposite rooftop with suspicion. The person wasn't wearing a Demon Slayer uniform, and the feeling from the sword he held wasn't the Nichirin Sword that demons hated.
"How ridiculous, a mere human who isn't even a Demon Slayer, seeking death!"
Daki's face twisted into a snarl, and an obi sash shot out with extreme speed.
"Uzui-san, it's dangerous!"
Tanjiro couldn't catch his breath, he shook as he stood up, but then stumbled and fell.
"Nezuko! Save—"
A sonic boom echoed, and Daki's sash missed, as if there had been nothing there to begin with.
Daki lowered her head, looking at the vanished Tanjiro beneath her feet, then stiffly turned her head to look at the figure behind her. That person was holding a red-haired youth covered in injuries.
Tsk tsk tsk, the thick-headed youth's life is truly tough, still able to fight after so much blood loss. Poor kid.
Seiichi transferred some energy to the youth in his hands, helping him stabilize his injuries.
"Seiichi-san, that's a demon, we are Demon Slayers, cough cough."
Tanjiro explained, breathing heavily.
"I understand. You focus on recovering. I'll handle the rest."
Seiichi said, then placed Tanjiro on the ground, letting him recover from his injuries.
"So, now it's our turn, emmm, demon?"
Seiichi's eyes slowly turned dangerous.
"Just you?! You—"
Daki, whose face was becoming increasingly fierce, was cut off mid-sentence as a tall girl with pink pupils and a bamboo muzzle kicked her away. It was the demonized Nezuko, who had rushed over after hearing Tanjiro's call.
"Is this one also a demon, Tanjiro?"
"No, she's not! She's my sister, Seiichi-san, please don't hurt her!"
Tanjiro grabbed Seiichi's hand and quickly said.
"Alright, alright. It's a bit chaotic, but she's not in a good state right now. Do you need me to calm her down first?"
"Then I'll leave it to you, Seiichi-san."
"You, how dare you ignore me!!"
Dozens of sashes shot out, each carrying a fierce tearing sound, flying towards Seiichi and Nezuko. Seiichi drew his sword, then sheathed it. All the sashes instantly shattered into dust, and pink silk floated in the air.
"So strong!"
Tanjiro was amazed.
The moment Seiichi sheathed his sword, his right leg bent slightly, and he instantly appeared beside Nezuko. While Nezuko was still in a daze, a crystal-clear, jade-like hand pressed onto her head.
Boom! A wave of air rolled, and the tiles behind Nezuko flew up. Her pupils constricted, and she fainted. Seiichi carried Nezuko back to Tanjiro and laid her down, then turned to look at Daki.
Or rather, he looked at Gyutaro, who was beside Daki. Green hair, a fierce face, a hunched body, a frame where every bone was clearly visible, yet it gleamed with the hardness of steel.
"My dear sister, he's not someone you can handle. Oh, good, good, he's handsome, and tall, unlike my ugliness."
"So jealous, so jealous!"
Gyutaro breathed rapidly, like a beast.
"What is that?"
Tanjiro felt his whole body stiffen, every cell screaming in fear.
In his eyes, it was also Upper Moon Six. Could it be that there are two Upper Moons, or is Upper Moon Six a combination of two demons? He couldn't figure it out. Uzui-san, Zenitsu, Inosuke, hurry up and come!
Tanjiro increased his breathing rate. He needed to quickly regain his combat ability to help Seiichi.
In the distance, Uzui had already rescued a large number of people bound by Daki's sashes and evacuated many townspeople along the way. He suddenly looked up in one direction.
"This way!"
He shouted, then burst forward with amazing speed in a straight line. Hearing the voice, Zenitsu and Inosuke also tried their best to keep up with Uzui's speed.
Seiichi, facing Gyutaro, was very calm. Mere Upper Moon Six was not enough to make him change his expression.
The opponent was about to move! He drew his sword, starting with a block. A fierce collision echoed through the sky, scattering dust, and a faintly visible shockwave dispersed the dust again.
"You're good, you can block my sickle."
Gyutaro let out a strange cry, chopping down, then cutting right... His movements were endless, and the clang of metal continued. Seiichi, holding his sword with one hand, had clear eyes, constantly swinging his sword to parry the sickle attacks from both sides. He was so fast that his afterimages were uncountable. He could even clearly see the expression of the cackling Gyutaro.
Then, it's time to increase the intensity. Seiichi changed his stance, quickly switching from a one-handed grip to a two-handed grip, his strength began to increase, and his speed became even faster. Sword light filled every corner, the figures of the two appeared and disappeared in space, and huge explosions sounded everywhere.
Chopping, slashing, picking, stabbing—the insights of basic swordsmanship flowed through Seiichi's mind. His changes in moves became more and more numerous, his attack directions hard to predict, and his defense perfect.
Countless wounds instantly appeared on Gyutaro's body, blood splattering everywhere, but they healed rapidly, and he remained unharmed.
Suddenly, Gyutaro gave a sinister grin, and Seiichi felt a sense of danger, quickly pulling back.
"Too late! Blood Demon Art: Flying Blood Sickles!"
The previously scattered blood formed into several sickles, and accompanied by Gyutaro's frontal attack, countless sickles simultaneously launched an assault on Seiichi.
'These things are poisonous, I absolutely cannot be injured. I'm not a shinobi like Uzui, my poison resistance isn't high. Looks like I can only break through head-on.'
Seiichi, having made up his mind in an instant, took a deep breath.
"Normal Breathing: Second Form - Revolving Heaven!"
The sword light instantly surged, and a net of sword energy tore apart everything that approached it. The storm grew from small to large, slowly expanding, directly rushing towards Gyutaro.
"Then come on! Blood Demon Art: Rotating Circular Slash - Flying Blood Sickles!"
The roaring Gyutaro transformed his hands into a blood-red tornado, which was a high-speed rotating sickle formed of blood. He directly crashed the blood-red tornado into the sword energy storm, and a huge explosion and white light covered the entire night sky. Uzui, several kilometers away, could clearly see it.
When the flying dust and stones settled, the one human and one demon, who had instantly pulled apart, stood quietly.
Seiichi looked at his long sword, which was now completely broken and shattered, while Gyutaro's arms had completely vanished, blood gushing out and splattering on the ground.
In this confrontation, although Seiichi was superior, for a demon, the recovery of his arms was only a matter of time.
"How pathetic, your sword is broken, but my hands can grow back."
Gyutaro grinned sinisterly, already seeing the victory of this battle.
Seiichi chuckled, twisted his neck, put away the broken hilt of his long sword, and clasped his hands together to stretch his knuckles, producing a cracking sound.
"I also know a little bit of martial arts."
But at this moment, a figure swiftly arrived from afar. After the dust dispersed, it was Uzui, who had rushed over!
"Looks like your luck isn't very good. Let's move on to the next round!"
Seiichi smiled.
