As the young Kaguya is raised into the adult Kaguya, her abilities are gradually unlocked: Byakugan, Rinnegan, and the nine-tomoe Rinnegan.

All-kill Ash Bones, Yomotsu Hirasaka, Eighty Gods Vacuum Strike...

Who comes into this world without some Chahela?

Don't force me, open the door and let Kaguya out!

Black Zetsu, call me Daddy and let me hear it.

Traveling through Naruto and becoming a civilian orphan,

How can you survive in the war-torn ninja world?

No golden fingers, no bloodline limits, no family resources.

How can we dance in this chaotic world?

…

"Of all those who have fought me, you are undoubtedly the strongest, even stronger than Hashirama! Come on, young man! Dance to your heart's content!"

"Dancing? I'll blow your head off!"

What bad luck! I choked to death after drinking a sip of warm water and traveled to this upside-down world!

What is upside down? It means that in a world where women are the mainstream, the attributes of men and women are reversed!

He thought he would live an ordinary life, but on the day of his high school graduation, a thing called the Sprite took him to a dimensional chat world that connected the heavens, changing his original life trajectory.

Yan Shuangying: How can someone like you change...

Xiao Yan: Thirty years on the east side of the river, thirty years on the west side of the river...

Spider-girl Shiraori: I...I...

Komon Ikki: Light is a bond...

Aqua: Hahahaha…

Kato Megumi: Oh my, I didn't expect that my presence is still so low here, I am inaction...

Ye Wuwei: ...The introduction is weak, please read the main text!

Heroic spirits, celebrated for their achievements, become heroes. Accidentally traveling through time and space, they gain access to the Heroic Spirit Achievement System, where their deeds are solidified into attributes, abilities, and skills... Slay demons and gain demonic special attacks. Slay dragons and gain dragon-slaying treasures. Steal a nation and gain weapons to plunder. Slay gods, slay demons, and confront three thousand worlds... The starting world is Demon Slayer. Expected storyline: Slash Akame no Yaiba, a comprehensive world of Warring States-era monsters (Inuyasha, Nura, Sekiro, Oda Nobuna, and more). P.S.: This is not a nerd's guide, as it contains alternate settings, so please don't read too closely... Thank you for your support! Even if you haven't read the original work, you can still read it as original...

The world of mutual understanding is the most ridiculous.

The peace of infinite dreams is the most hypocritical.

Darkness, cold-bloodedness and cruelty are the truest portrayal of this world!

So, you wanna dance too!?

Realization of fantasy is the ability to make the things firmly described in the mind become reality and create something out of nothing. Through the form of imagination, the ability to create natural phenomena, physical phenomena, man-made objects, divine creations... out of thin air.
