(Infinite Flow) (Anime Crossover) (Game) (Harem)
The protagonist, Xia Xingci, transmigrates to a god-like space filled with public spaces like plazas, exchanges, and arenas, and teeming with top-tier experts. Here, a survival-of-the-fittest system prevails; those who don't grow stronger will die. As the weakest among them, the protagonist immediately faces the god's annihilation.
Fortunately, the first instance that Xia Xingci, a pure-blooded human, entered was NieR: Automata, where the androids left behind by humans fought for the glory of humanity.
During this process, the protagonist also gained the favor of YoRHa II Type B.
2b: "I will fight not only for your glory, but also for your freedom. Take me to the God Realm."
(The protagonist follows a technological advancement path, primarily focusing on cybernetic body modification.)
