"Booyah, bitches. Take that, Yorichi," a black-haired man said as he moonwalked in front of a dead family.
Finally, he had become a true immortal.
He had conquered the sun.
"after all these years I have succeeded" he muttered.
As he turned around, he looked up to see a blue-haired man, his hand holding a glowing blue sword.
"Who are you?" Muzan asked in confusion.
He had not seen this guy in any version of Demon Slayer.
Yes, Demon Slayer Muzan was a transmigrator who became a demon with morals—well, a little moral.
"My name is Steve," the man said, and in the next moment, the blue sword separated Muzan's head from his body.
The blue-haired man looked at him briefly before walking away.
"Why, man… why?" Muzan thought.
He had suffered for centuries to conquer the sun, and then some random guy from Minecraft came and killed him.
It wasn't even the protagonist squad that ended him, but a man from another universe.
Why was a man from another universe even here?
Well, it was a pretty good life, I had…
…Muzan muttered as he waved his hand, his body disintegrating.
"Well, Tanjiro, you won," muttered Muzan, closing his eyes.
…
"Graaaaaa!"
"Raaaaaay!"
"Kyooooooo!"
Three beams from all directions were about to collide—devastation imminent.
But in the middle of it, a black-haired youth appeared.
"I am alive once again!" he screamed—
—before stopping, noticing he was in the middle of a battle between three gods.
"Well, third life… I enjoyed every second I ha—"
The third life had ended.
"Seriously, you guys," Mm muttered before looking at them.
"Until the day you stop fighting, I will seal yu and cast you out of my world."
He raised his hand. The three beings were turned into three orbs: Alpha, Omega, and Delta.
Blue, red, and jade.
The orbs were sent flying through the cosmos.
…
Water. All around me… water.
"Haaaa—blurb—too much water!" a black-haired man said as he stood in the middle of a stream.
"Yes! I am alive! Yes, I, Muzan, am alive!"
"Take that, Yoriichi!"
"I don't know why… but ditching Yoriichi makes me happy," Muzan muttered as he pulled his hair back.
"Let's see," Muzan said as he extended his arm into the sun.
"OW—ow ow ow—the sun is fucking cooking me!?"
It didn't disintegrate him, but his body was turning charred.
"Why!? I worked so hard—so long—to grow this strong. Why am I still weak to the sun? Why is my power level so low!?"
Muzan stumbled toward the nearest tree.
Bang—he punched it. Only a slight creak was heard.
"I… am weak," he muttered, staring at the world around him.
"Fourth life… I wish this one would be peaceful."
"Oh, shooting stars in the day," he muttered.
There were three.
"Then maybe my wish will be granted."
Wait… why are the stars coming closer—
"FUCK! That's asteroids!"
Before Muzan could dodge, his fifth life had ended.
Now, let's go to his sixth life. Where the story begins.
Slash! Slash!
Katanas were clashing together as three men rushed toward each other.
"Water Style: Water Dragon!"
"Earth Style: Earth Dragon!"
"Fire Style: Fire Dragon!"
All three executed their techniques at the same time. The jutsus collided, triggering a massive explosion.
BOOOOOOM!
The ground shattered as the three clan heads stared one another down.
"Hagoromo, retreat!" one of them yelled, as his people pulled back slowly—
Their numbers declining fast—casualties rising.
The Senju and Uchiha clans clashed, uncaring about the Hagoromo people caught in between.
Their leade was still locked in combat, swords flashing as he fought both clans at once.
At the same time, a black figure watched.
Not at the warriors.
But at another figure… a young child who was watching him.
"Who are you?" Zetsu asked, joining his hands, eyeing the child who looked no older than twelve.
Something about the kid was deeply unnerving.
"Muzan. Kibutsuji Muzan," the child said, his predator eyes scanning the battlefield with calm confidence.
But—
"FUCK FUCK FUCK—I'm in a world where I'm not even the strongest!" Muzan screamed internally.
"Not even in the top twenty!? Or maybe I'm even lower…"
"Boy," Zetsu said, voice calm, "do you want to solve the wars? Do you want to bring peace?"
Classic manipulation tactics, Muzan thought, giving no reply.
Zetsu didn't know why… but he felt this human—this child—might be able to help him.
So, first thing to do?
Become the good guy in front of the kid.
"WATCH OUT!" Zetsu yelled, suddenly lunging toward Muzan.
