[Hundred] + [Honkai Impact] + [Honkai Iron] + [Genshin Impact] + [Zero Zone] + [Chat Group] + [Anime Crossover]

During the Third Honkai Impact, Kiana, having awakened her past life memories, obtained the divine technique: Ultra Instinct. Later, she joined a chat group in the Honkai Impact universe, became the Immortal Ship Alliance, and became the Taiyin General. However, the more she looked at this chat group, the more strange it seemed...

Ox-Horse of the Rebirth Hall: I am Kiana

Gojo Kiana: I'm Kiana too.

Kaslana: I am also Kiana.

Uma Musume Pretty Derby: I'm Kiana too!

...

Kiana: You're all Kiana, so who am I?

I understand now, this world is just one giant Kiana!

So Kiana uses consciousness swapping to help other Kianas (herself) solve problems (while taking the opportunity to slack off and have other Kianas work for her).

Wangshu Xianzhouren: Why does the general's personality change every now and then...?
