My name is Kiana Kaslana, but not the paramecium K423.

Nor the real Kiana.

I am K422, but I don't like this name.

I prefer to be called Kiana Shaniat rather than Kiana Kaslana.

I have a mother who is the most powerful Valkyrie.

I want to be as powerful as her, because beauty is only worthy of the strong.

Therefore.

...

...

I really want to kill Bishop Otto.

In the name of the end, I am the incarnation of Honkai!

Starting from Academy City, the road of expansion of the will of the collapse.

I, Selene, will eventually rule (invade) all worlds!

PS: It is a story of a person who obtained the template of the Herrscher of the Honkai, doing things in various worlds. (Note: The development is slightly dark, and the protagonist is single. It is determined to travel through the world: Academy City, Zhan, Red Eyes, FATE, Honkai World, Marvel Universe, etc., the order is to be determined.)

The wisdom of countless worlds has never found a way to end the collapse.

Civilization and collapse seem to be entangled like this.

However, an accident allowed countless people to see that tiny possibility.

Also in Saint Freya, the genius lady Kiana and the paramecium Kiana found that they had exchanged identities with another "self".

The encounter between the two across the world began to be presented in the form of a video and played in front of everyone. Gather the wisdom of all civilizations to find a possibility to defeat the collapse.

Paramecium: "The God Killer Armor in this world is so powerful."

Theresa: "Compared to Cecilia, I'm still too bad."

Otto: "The me in another world betrayed Kallen's faith."

Raiden Mei: "I am such a powerful person?"

Kevin: "I beat MEI?"

...

When everyone who watched the video looked back suddenly, with the knowledge of the future, the dawn of hope began to magnify infinitely.

A few years later, the Herrscher of the End came.

The End: ? ? ?
