Honkai Impact 3rd: I Am the White Night

(The author's writing isn't very good, and I may leave plot threads unresolved. Please forgive me, and bear with me while reading.)

[Also known as Honkai: I Am the White Night, and Also the Manager]

One day, a baby born from a river fell from the sky. They had six wings and a flawless face, both divine and bloody.

At last, flames scorched their white wings, and they descended into this world beneath the night sky.

Later, the “baby” was turned into a K424 by a certain blond man. After a long and winding series of events, K424 inexplicably regressed into a Plague Doctor. Then, because they looked so much like the Manager, they temporarily took the name X. A certain System came to find them and said they needed to release the Light Seed to save the world.

With no other choice, X accepted the task. After all, this was a fight for everything beautiful in the world!

…

X gazed resolutely at the successfully launched Light Seed, the faintest hint of a smile on their lips, and entered it.

“My name is White Night…”

As soon as the words left their mouth, X, blessed by Abnormalities on all sides, once again became her.

And this was only the beginning of the story… (Around the Third Great Honkai) [Not yet firmly decided]
