Reincarnation as Lower Rank Five in Demon Slayer

Mizuko was returning home from gathering firewood outside at night when she suddenly saw a figure walking towards her house.

Nezuko popped up from above her head: "Who's that?"

"The quiet environment and the pitch-black night are really boring."

"Where exactly is the blue spider lily?"

Having lived in darkness for a thousand years, Muzan looked at the brightly lit hut before him and was disgusted by the countless times he had broken into different people's homes to eat them.

The unchanging life in the darkness, living without sunlight for thousands of years, made Muzan yearn to overcome the need for sunlight.

"Sir, what are you doing here? Are you lost because it's too dark?"

Nezuko, carrying dry firewood, walked up to Muzan and asked.

Upon hearing the sound, Muzan turned to look at Nezuko.

This was quite something; it was a completely new and unique constitution that I had never encountered before.

Muzan, who originally intended to eat the girl to fill his stomach, immediately abandoned his murderous intent and prepared to turn her into a demon after seeing that the little girl in front of him had a constitution he had never encountered before.

Noticing Muzan's change in expression, Nezuko felt a chill run down her spine and involuntarily took a few steps back.

Upon seeing this, Muzan flashed in front of Nezuko, grabbed her by the neck with one hand, and lifted her up.

Sharp fingernails pierced Nezuko's neck and began to inject her demonic blood. Nezuko's body began to undergo strange changes as Muzan's blood was injected, but Muzan did not notice these subtle changes.

"Oh, not bad! Blood that can turn more than a dozen people into ghosts can't even turn you into a ghost."

Let me see where your limits are.

Muzan, caught up in a playful mood, immediately increased the blood flow, completely disregarding whether the little girl in his arms could withstand it.

Muzan's violent blood transfusion immediately caused Nezuko to feel a stinging pain all over her body, and she instantly lost consciousness because she had never experienced anything like this before.

"You bastard, stop right now!"

Tanjuro's voice came from the direction of the house.

Tanjuro, leaning on his cane and holding an axe, was unusually angry. Having just realized Nezuko hadn't returned for a long time, Tanjuro had a strange, bad feeling. He came out with his axe and cane only to see this scene before him.

With veins bulging on his axe-wielding hand, Tanjuro, leaning on his cane, came out and saw Muzan's brutal treatment of his daughter Nezuko. His eyes were filled with murderous intent, and the moment he saw Muzan, an endless stream of power surged from Tanjuro's body.

Perhaps because of his anger, Tanjuro's ailments seemed to disappear at that moment.

"Hmph! Another one coming to die." Muzan turned his head away disdainfully.

What kind of day is this? Nobody's afraid of him anymore! How dare he yell at him? This rude guy must pay the price. Muzan thought to himself as he turned his head.

But what I found when I looked at it was quite shocking.

"Holy crap! Yoriichi!"

The moment Muzan saw Tanjuro, he felt a chill run down his spine and involuntarily released Nezuko.

In that instant, Nezuko's father, Tanjuro, threw aside his cane, picked up his axe, and swung it at Muzan. His speed was as fast as light, his ferocity as fierce as fire, like a shooting star with a trail of flame, carrying an unstoppable momentum.

Upon seeing that this figure overlapped with the blurry monster from his memory, Muzan was so frightened that he immediately dodged away. He made no attempt to block it at all.

Even if Tanjuro's weapon wasn't a Nichirin Blade but just an ordinary axe, Muzan wouldn't dare to take it head-on.

Dodge this man who bears a resemblance to Yoriichi in your mind and possesses the attack speed of an Upper Moon.

Muzan breathed a sigh of relief. It turned out that Yoriichi wasn't a damned mortal who had startled him. Hundreds of years had passed, and Yoriichi, who was in a mortal body, had long since died of old age in his battle with Kokushibo. He was just scaring himself.

After forcing Muzan to retreat, Tanjuro immediately bent down to check on his daughter Nezuko's condition.

"It's okay, I just fainted."

After checking and finding Nezuko unharmed, Tanjuro breathed a sigh of relief. He then immediately stood up, grabbed his axe, and aimed it at Muzan.

This ghostly creature with a human-like appearance is dangerous; it must be killed and cannot be allowed to leave.

From the moment he saw Muzan, Tanjuro knew that killing this demon Buddha was his mission. No one said it; it was just his instinctive feeling.

With earrings featuring the Yoriichi sun motif and a sword-wielding pose reminiscent of Yoriichi, who exactly is this man?

"Hinokami Kagura: Crimson Mirror of the Blazing Sun"

Before Muzan could think any further, Tanjuro arrived in front of him in a flash and swung his axe left and right.

Seeing the attack before him, Muzan dodged again, but his pupils trembled uncontrollably.

Sun Breathing? That's impossible. After Yoriichi died, he clearly killed everyone who might have learned this breathing technique.

Muzan stared at Tanjuro in disbelief, and at that moment, flame patterns began to grow on the black markings on Tanjuro's forehead, just like Yoriichi's.

"A Transparent World, Fully Open"

After flame patterns grew on the mark, Tanjuro's Transparent World immediately changed, and Muzan's skin began to become transparent in his eyes.

"This is!"

As Muzan's muscles began to appear transparent in his eyes, Tanjuro finally saw Muzan's body, which had multiple brains and hearts.

"This is impossible!"

Sensing the change in the man before him, Muzan was immediately frightened; the man was growing stronger at a speed he could not comprehend.

Run! Run right now!

Upon realizing this, Muzan instantly exploded into thousands of pieces of flesh and fled.

Upon seeing this, Tanjuro quickly swung his axe at the meat, but only managed to cut a few pieces.

At that moment, Tanjuro suddenly felt his body go limp. As Muzan's escape reached its limit, he collapsed forward to the ground.

……

Inside the Infinity Castle, all the pieces of flesh that Muzan had escaped immediately merged into a body with its eyes closed. Muzan immediately opened his eyes to check his injuries and found that he was fine; even the pieces of flesh he had slashed were unharmed.

Seeing this, Muzan finally breathed a sigh of relief. It was good that there would never be another monster like Yoriichi.
