It starts with a demon-slaying sword, starting from the world of Demon Slayer: Kimetsu no Yaiba. In a world where ghosts eat people and people kill ghosts, the time traveler Bai Yu signed a contract with ghosts and gods and became a being that transcended ghosts.

Want to know what it's like for the Blood Emperor to not go bald? Then come and see for yourself. A work by the Rebellious King.

The Blood Emperor stomped the flying squirrel on the ground, laughing heartily, tears welling in his eyes. Finally... finally, he wouldn't be losing hair anymore, he wasn't balding.

In Konoha year 60, Naruto's generation of genin were taking the Chunin Exams for the first time. A sudden "horror quiz" game caused the "original story" to begin to crumble from that moment! Obito: What's it to me?! Why is everyone broadcasting my declaration of the Fourth Shinobi World War, gathering the Ten-Tails, and being tricked by Madara into doing eighteen years of pyramid schemes?! Madara: I also want to know, who made everyone see me having my heart ripped out time and time again?! Wait! Black Zetsu, don't run away!! Itachi: Please, have mercy! I still need to make my foolish younger brother hate me. It's not appropriate for you to broadcast my eternal love for him to the whole world like this… Shisui: Um, I was just jumping into the water, can we not broadcast it globally?! Sasuke: Disgrace! I'm actually the reincarnation of Uchiha Madara's chakra—the one who was "tricked by the black mud for his entire life"?! Killing Naruto is my destiny?! Madara: Kid, you want to dance too?! Izuna: Who dares to insult me, *san?! ..

Traveling through the world of Demon Slayer, Shigure opens the role-playing system of the universe.

The higher the missions completed and the degree of character restoration, the stronger the power gained.

The first task required at the beginning is Bai'e.

"? Bai'e beats Wuzhan? Doesn't having hands do that?"

"Nanook... uh no, Muzan Kibutsuji, I bring destruction upon you!"

Muzan Kibutsuji: "No red blade? No markings? Are you also a pillar?"

Shigure: "Pillar?... Pillars are considered pillars."...

Muzan Kibutsuji: "It's useless. Unless I wait until the sun rises, I can be resurrected even if only a piece of flesh is left..."

"I am"

"?"

"The blazing sun will eventually rise!"

【Team Zhutian, dark, behind the scenes. 】

This is a journey of evolution of a dark life form.

Many people call me the Lord of the Black Mist, but I am more accustomed to hearing them call me the Lord of R'lyeh.

The Seventh Hokage, Naruto Uzumaki, sacrificed himself in the final battle against the "Otsutsuki Main Family," an enemy from the stars, to protect the ninja world.

When he opened his eyes again, he found himself back in the cold hospital bed he had been in when he was three years old.

Along with the memories of despair, the [Fire Seed System] from an alien civilization also awakens.

Sign in at the start and directly merge the origins of the three great dojutsu: Byakugan, Sharingan, and Rinnegan!

In this life, he is no longer the orphan yearning for recognition, but has wielded divine power since his birth.

In this life, he will turn back all the unresolved grievances:

The Uchiha clan was wiped out? Itachi, there's no need for bloodshed, I'll break your shackles!

The Akatsuki are collecting Tailed Beasts? Nagato, I will end your suffering!

When Madara Uchiha descended with pride, behind him stood the entire ninja world, united as one.

However, this was only the beginning. From beyond the stars, true terror was already casting its gaze.

But this time, Naruto Uzumaki will stand before millions of people and, in the name of God, declare to the stars:

"This world will be protected by me. The blood debt of the Otsutsuki will only be repaid with your civilization!"

She woke up to find herself transformed into the female protagonist of her next book! What... what kind of incredible plot twist is this? Is this a dream come true? No, no, no! Just because she likes writing Yuri's novels doesn't mean she wants to be a girl. Fine, she could get used to the setting; being a girl isn't so bad. But... what's with this book called *The Bonapé Codex*? This everyday life... seems a little different from what she imagined. That little girl with green hair, wearing a dress with octopus or squid prints... could she be...?

Waking up, he found himself reborn in the world of "Covering the Sky," becoming Ye Tiandi's Mercedes-Benz. Just as he sighed at the hardships of life, he encountered other versions of himself from countless worlds. Their power was completely shared, an endless accumulation of Rocks. A single Rock was not strong; multiple Rocks, their strength was uncertain. After sharing power, he became not only the true form of an imperial weapon in the "Covering the Sky" world, but also a cosmic overlord in Marvel, a supreme demon god in the abyss, the father of all gods on Mount Olympus, and the progenitor of the Dao in the primordial world. Even more so, an infinite god! Rock: Plans changed, sweeping across the heavens.

(He is kind to his own people, but very perverted towards ghosts, and tortures them fiercely. There are many elements.)

Su Yu wears Demon Slayer and becomes stronger by writing in his diary every day, but he doesn't know that his diary will be seen by others.

I got the Zoro sword at the beginning, and I thought I could start the road to becoming a dragon hero directly, but I didn’t expect that this sword came with a debuff of getting lost!

He got lost just by turning a corner when he went out. A normal person suddenly became directionally challenged. Su Yu felt very angry but had no place to vent.

But when he got the "Undead Killer" that could cause more damage to ghosts, his whole demeanor suddenly changed.

"A ghost, right? You like to eat people, right? You're more evil than me? I'm even more evil than you!"

So.

The style of Su Yu's diary also changed suddenly.

[I nerfed a few more ghosts today. I've been stuck in this mess for so long, and now I can finally let it out! ]

[Don't run! You guys are good at eating people! Now let's see who will kill whom!]

[The screams of ghosts are truly delightful. Even if you scream at the top of your lungs, no ghost will come to save you. Just surrender!]

I, Liuyun, a true villain, have traveled through countless worlds simultaneously. I don't have a system, no grandfather in a ring, and neither do I possess the same luck as the protagonist. All I can rely on is myself, or rather, ourselves. 'Hokage' Liuyun: I am the eldest son of the Fourth Hokage, a true fox demon. 'Demon Slayer' Liuyun: This world can only have one Demon King, and that is me. 'Pirate' Liuyun: I hold a sword, slaying all injustice in the world. 'God Slayer' Liuyun: Those who live alone are either beasts or gods!
