I, Uchiha Hikaru, have joined the chat group.

Chapter 55 concerns the fact that Yoriichi Tsugikuni was reincarnated as a girl.

Before he could finish speaking...

Uchiha Hikaru launched another thrust.

As she moved, rings of flame appeared around the edge of the short sword—a scene strikingly similar to that of the swordsman named Yoriichi Tsugikuni from hundreds of years ago!

"Aaaaaah!!"

The Muzan cells trembled violently!

That indescribable fear was even transmitted through blood to Lei, making him feel it as well!

In the nick of time, Rui, relying on his extremely strong survival instinct, frantically mobilized the power within his body, his ten fingers interlacing: "Blood Demon Art: Scrolling Wheel!"

Numerous spiderwebs appeared all around, weaving this space into a vast, inescapable net. Even more enormous amounts of silk wove a swirling cocoon, which was launched towards Uchiha Hikaru!

Faced with this desperate, all-or-nothing move.

Uchiha Hikaru's response was nothing more than a simple circular slash: "Sun Breathing... First Form: Round Dance!"

A flash of light.

With a perfectly round arc sweeping across, Lei's final, all-out killing move was easily neutralized. Where the blazing blade and ring of flames passed, all the spider silk melted and disintegrated as if ice and snow were exposed to the sun. Then, a ball of black and red flames swept across Lei's body with the blade, instantly slicing him into several pieces.

The pain, like being burned by the scorching sun, spread rapidly, and the cut wound showed no signs of healing.

"really……"

It's "Sun Breathing"!

Exhausted to the point of despair, I started having a mental replay of events.

But at that moment, the black flames began to quietly recede, and in their place came black runes that spread from Uchiha Hikaru's hands, swimming rapidly all over his body like tadpoles. Then, with a low shout of "Five Elements Seal," the several pieces of his exhausted body were sucked into a scroll and firmly sealed.

After doing all this.

Uchiha Hikaru coldly scanned his surroundings again, and only after confirming that the aura of exhaustion had completely disappeared did he form a hand seal and dispel the transformation jutsu.

That's right.

She certainly doesn't know anything about "Sun Breathing".

Both her red hair and the "marks" on her forehead were created using her transformation technique. "Round Dance" and "Yanghua Thrust" were imitations she made based on her understanding of the Demon Slayer storyline—basically, one is a thrust and the other a circular slash, the most basic sword techniques, so she could learn them pretty well.

As for the "Crimson Blade"...

It was simply a fire-style technique. However, she added a touch of Amaterasu to that crimson flame.

This disguise wasn't perfect, but it was enough to fool Muzan.

—Tanjiro's earring alone was enough to frighten Muzan into not daring to attack him personally. So, how much psychological pressure could someone with the same hair color and markings as Yoriichi Tsugikuni, who could use the "Sun Breathing" sword technique with over 70% similarity, and who could actually inflict wounds that wouldn't heal... possibly put on Muzan?

Uchiha Hikaru was very curious about this.

"Just as I guessed, Amaterasu's lethality against demons is far greater than that of ordinary fire-style techniques, and it should also be far greater than that of the true 'Sun Breathing.' If I had recalled Amaterasu ten seconds later, this guy would have been completely incinerated..."

She didn't really want to kill Lei.

After all, experimental subjects like the Twelve Demon Moons are very precious. Every one that dies is one less. We can't afford to waste them before we catch Muzan, the source of mass-producing demons.

As the last rune disappeared, Uchiha Hikaru stuffed the scroll into his pocket, casually tossed away the short sword that was about to be melted by Amaterasu, and then returned to "Dad" and sealed away the guy who was still standing there as punishment.

"……knock off!"

Until this point.

Uchiha Hikaru stretched and called Bulma out.

"...Gulp."

Bulma, now back to her original size, looked at the mountains and forests around her, which had been ravaged by flames, sword energy, and Susanoo, and swallowed hard. "Hikaru, what happened to all this? It wasn't all from your battle with those two demons, was it?"

"Um."

Uchiha Hikaru nodded: "I originally wanted to control the situation a little, but I didn't expect that I didn't learn the 'breathing technique' I got from Tanjiro and the others properly, and I accidentally made it like this."

"By accident..."

Bulma gave Uchiha Hikaru a complicated look: "I believe you."

However, this issue wasn't important, and Bulma didn't press the matter further. For her now, the most important thing was...

"Um... Hikaru, could you please keep an eye on things outside for me? I'm going in to wash up and change my clothes, it'll be quick!"

With that, Bulma blushed and tossed out a capsule, which conjured a small house out of thin air on the hillside. Then she went inside to take a bath and change her clothes.

The sound of rushing water came from inside the room.

Hikaru Uchiha put his hands behind his head, threw himself onto the soft grass, and looked up at the night sky.

"At this time, the Pillars of the Demon Slayer Corps should be on their way, right?"

"I wonder if Muzan Kibutsuji saw my performance just now. If he did... his expression right now must be priceless, right?"

……

An alternate dimension, an infinite city.

The laboratory table, which was filled with various utensils, was pushed to the ground, and various glass products were shattered all over the floor.

The black-haired youth with crimson eyes hugged his arms tightly and curled his body into a ball.

Overwhelmed by tension, his pale face flushed, the veins on his neck bulged, and his pupils narrowed to slits. He exuded a gloomy and oppressive aura, so much so that the surrounding wooden floorboards cracked and creaked, appearing as if they were about to collapse.

"It's him...it's him!"

"That appearance, that pain... there's no mistake... it's that man's Sun Breathing!"

"Why? Why! Why isn't he dead yet?!"

"Aaaaaah—!!!"

At this moment, Muzan's five brains almost completely shut down, leaving only the image of the red-haired man from hundreds of years ago and the image of the red-haired girl he "saw" through Rui, flashing and intertwining in his mind. In a daze, the two figures began to overlap, especially the words, "What do you take life for?", which made Muzan realize one fact—

It's him!

Yoriichi Tsugikuni!

The human being who terrified him has crawled out of his grave!

He... he was even reincarnated as a girl!!

for a long time.

Muzan finally recovered a little from his fear, raised his head, and let out a hysterical roar at the figure on the platform.

"Naruto!! Girl!!"

An indescribable pressure erupted, directly shattering dozens of floating wooden rooms around it. Even the woman in a kimono sitting on the high platform with her long hair covering her face felt the pressure. The veins on her hands, which were holding a pipa, burst open, and thick blood gushed from her throat.

"...Kuroshibo, bring Kokushibo here!"

"immediately!!"
