Demon Slayer: The Great Swordsman's System, Disciple of Yoriichi

In a small town near the bamboo forest, Si Shu rested briefly. His injuries had mostly healed during the past few days of travel. After nightfall, he asked the townspeople about Yoriichi.

"You mean that young man in the samurai uniform with the strange marks on his face? Just follow this path and you'll find him," an old man told him. Learning that Yoriichi had gone deep into the forest, Si Shu followed the path. Before long, a figure appeared ahead.

It was Yoriichi Tsugikuni, whom he hadn't seen for days!

?! Yoriichi was slightly surprised to see Si Shu here. "Your injuries, what happened?" he asked, pointing to the bandages wrapped around Si Shu. He didn't understand why his student, who had only gone to find his brother, would end up like this.

Si Shu was about to speak when his expression suddenly changed. At the same time, Yoriichi also seemed to sense something and frowned. They both turned to look down the other end of the path.

There, two figures were slowly walking towards them.

A man with a pale face, short black hair, and a cold smile.

A beautiful woman with a slender figure, exquisite makeup, and a face full of sorrow.

The Demon King, Muzan Kibutsuji, and Lady Tamayo.

The moment he saw Muzan, Yoriichi's expression changed. For the first time in his life, his face was filled with an icy coldness. In that instant, a single thought flooded his mind.

I was born into this world to defeat this man.

He drew his Nichirin Blade, its tip aimed at Muzan. Facing the drawn blade, Muzan's expression remained indifferent. Suddenly, he noticed Si Shu.

"Eh? You're not dead?"

"Yes, alive and well. Are you disappointed?" Si Shu retorted without hesitation.

"You two know each other?" Yoriichi glanced at Si Shu, as if asking. His own student knew the man opposite them, the man he was destined to defeat. Fortunately, from their tone, their relationship was not a close one.

Shaking his head, Si Shu told Yoriichi about Muzan and Michikatsu. The moment he finished, anger appeared in Yoriichi's eyes for the first time. The man standing before him was the source of all evil, the Demon Progenitor. At that moment, Yoriichi understood why he had been born with this gift. It was to slay Muzan!

Observing Muzan closely, Yoriichi noticed his strangeness. He was filled with a violent life force, like magma about to erupt from a volcano, yearning to devour everything around it.

"I don't know how you found out my identity and managed to stay alive, but none of that matters anymore," Muzan said, slowly raising his hand under the moonlight. "I've lost interest in you swordsmen who use breathing styles."

The moment he finished speaking, Muzan's arm vanished. Then, the sound of tearing wind echoed as something rapidly approached Si Shu and Yoriichi. Si Shu drew his sword and stepped in front of his master. The next second, a clang rang out, and a shockwave exploded outward. As if struck by something, Si Shu's body was sent flying.

Muzan raised an eyebrow, a hint of confusion on his face. He hadn't expected his attack to be blocked by this little kid. It turned out his arm had "disappeared" because it had been swung at high speed—a speed that broke the limits of the human eye. The power of Muzan was clear.

"I'm fine!" Si Shu shouted to Yoriichi as he flew backward. That single blow had shown him that he was not yet strong enough to defeat Muzan. In that case, he would leave it to his master.

Nodding, Yoriichi focused his full attention on Muzan. Gripping his Nichirin Blade, he charged. With a cold smile, Muzan swung his arm again. It transformed into a long strip of flesh tipped with a sharp bone blade. Its range and speed were unlike anything Yoriichi had ever seen. As he dodged, countless bamboo stalks were sliced apart, the sound echoing into the distance. In Yoriichi's perception, this attack was completely different from the earlier probe. Even a graze would be fatal! It was the first time in his life he had felt a chill run down his spine.

Meanwhile, Si Shu stood before Tamayo. "Lady Tamayo, I know about you."

Looking at the young Demon Slayer, a hint of doubt flashed in Tamayo's eyes. She was curious why he wasn't trying to kill her, a demon. She wondered if what he said was true, and if so, how he knew. The more she looked at his face, the more familiar he seemed, as if she had seen him somewhere deep in her memory.

"You and I will just watch," Si Shu said, sheathing his sword and turning to face the battle between Yoriichi and Muzan.

Tamayo quietly walked to Si Shu's side and tilted her head. "May I... sit next to you?" Though a bit surprised, Si Shu nodded. Smoothing out her clothes, she knelt beside him. The two of them, without a word, silently watched the duel.

Ducking and bending, Yoriichi once again dodged Muzan's attack. In his eyes, Muzan's body structure was laid bare. He had five brains and seven hearts!

At that moment, Yoriichi finally completed his ultimate sword technique.

Sun Breathing, Thirteenth Form.

By using the first through twelfth forms continuously, creating a seamless, unending cycle. That was the principle of the Thirteenth Form.

His Crimson Blade, wreathed in flames like a coiling dragon, slashed through Muzan's body.

Schlick!

With the sound of tearing muscle, Muzan's body was effortlessly cut into several pieces. His eyes bulged as if he had just realized he had been attacked. His gaze was filled with confusion and terror; for some reason, his body showed no signs of regenerating. Even propping up his severed head with his broken arm did nothing to reattach it.

Watching Yoriichi's technique, Si Shu's body trembled with excitement. He had tried to use the forms continuously before but could never connect them perfectly. Today, after seeing Yoriichi's Thirteenth Form, all the questions in his mind were answered. At that moment, he, too, grasped the Thirteenth Form.

[Congratulations to the Host for unlocking the skill: Sun Breathing, Thirteenth Form.]

This is the true Sun Breathing. Admiring it, Si Shu also knew the battle was over. Having grievously wounded Muzan with a single blow, Yoriichi turned and walked up to him. The next second, a Nichirin Blade was placed on Muzan's neck.
