Shen Qiu transmigrates to the world of Honkai Impact 3rd, in the Previous Era, where his legs are crippled by Honkai corruption. Just as he's about to become the Previous Era's Bronya, he binds himself to the Fairy Elysia System. As long as he gives the Thirteen Flame-Chasers either a sweet moment or a tragic one, he can obtain a Herrscher's authority.
Shen Qiu: "What made you lose your way? Honkai Impact 3rd?"
A sacrifice no one ever knew about, yet one that had always been there.
A hope that had just appeared, only to vanish in an instant.
The truth, sincere all along, dismissed as a lie.
A tragic ending that could have been prevented if only the truth had been told.
Shen Qiu: "Thanks. We Honkai Impact 3rd players love seeing this."
Mobius, Elysia, Pardo: "Stop making us suffer!"
