To create Honkai Impact 3rd in a world where Kallen exists.

"Kallen, live on." A blond man descended from the sky and saved her... Karen had this dream countless times.
Let the world completely forget Otto.
From then on, Luo Mo's Honkai Impact 3rd was born with the support of Destiny.

"Welcome, noble and pure soul." The pink-haired girl turned around and smiled, just like the first time they met.
Theresa was shot with several arrows. Who was it that was persecuting the dignified headmistress?
Despite her setback, Duck's aura remains undiminished; Rita, though defeated, is ready to rise to glory once more!
Golden Courtyard vs. St. Freya: Fu Hua tops the voting list.
Who is persecuting whom? And who is being called inhuman?
Luo Mo pointed to the bump on her head and cried out, "I'm the victim!"
A moonlit embrace, the Stargazing Prince... the game is full of regrets.
In the end, the audience realized that the world is truly wonderful, except for that game, Honkai Impact 3.
P.S.: The early chapters are weak; I suggest starting from Chapter 10.
PS: Honkai Impact 3rd universe, the protagonist is a game enthusiast, no Otto, but has a mother-in-law.
