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.

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!"

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"

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?! ..

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!

Adorable anchor Kurama Neon: You're my Prince Charming! Naive secretary Izzy: Weird! I'm Shumagia, why do I blush when I see you? Xingguo's mother: Come, Master, sleep on your lap...

I'm Aizen, and I'm panicking right now. I thought I was at my peak from the start, unstoppable, but can anyone explain what happened to that big brother I remember as "Vongola I"? This doesn't seem like a pure Bleach world!

I originally thought that if I could just stay awake until the plot started and hypnotize myself together with Kurosaki Ichigo, I would be able to reach the pinnacle of my life. However, this doesn't seem to work in this unfathomable world, so I can only go to different worlds and act out various identities to accumulate strength and the power of heroes, so that I can once again become Lan Da in people's eyes!
