Playing Firefly: Cuddling Up in a Genshin Impact Apocalypse

【Gender Bender + Yuri + Post-Apocalyptic Daily Life + Overpowered Protagonist】 She transmigrated and became the spitting image of her new wife, Firefly. My wife is actually me? But Firefly, determined to carry on despite her disability, insists that even after losing her little bird, she still has to find a girlfriend! But why is this the world of Teyvat instead of Honkai: Star Rail? Oh well, they're pretty much the same! And who knows, maybe she can even use her superior technology to crush everyone here, jump into her mecha, and shout, “The times have changed, people!” Set the sea ablaze, hmph ╯^╰ Wait, that's not right. Why am I a frail, helpless girl? This is bad. I'm so cute, so we're all girls. We can't do this. Don't come any closer! Don't touch me there! The Glamoth Queen's Transformation System has awakened!
