Offering Genshin Characters to a Terrible World

(Otherworld, growing an organization, Honkai: Star Rail, Genshin Impact, Zenless Zone Zero, mainly focused on development, with both daily life and battles, no putting others down, absurd comedy, some angst, not cozy or comforting, slow burn, funny) As characters from the MiHoYo games enter this world one by one, and the MiHoYo faction grows ever stronger, how will the other countries of this otherworld, its traditional Demon Kings, and its transmigrators react? Overthrowing this ignorant, feudal otherworld should be a piece of cake! (Later on, some crossover anime elements may be added, such as Overlord and That Time I Got Reincarnated as a Slime, but they’ll be on the opposing side.) (Note: Once there are more characters from the MiHoYo games later on, this may shift into an ensemble cast story. The protagonist will still be the driving force, but will remain off-screen most of the time.)
