I Was Reborn as the Protagonist, and You’re Telling Me the Other Side Has a Villain System?

(This book is also known as The Train of Life Choices. It features a major antagonist who defies fate. The book has been rebooted, all the main plotlines have been deleted, and the story has been completely rewritten. The protagonist changes sex but does not become a yuri character or marry into another family. It’s a story of ruthless combat and raising an army, with all the recruits being protagonists who have changed sex. As for the protagonist’s abilities, they come from ancient artifacts, like in that magical-girl story, except the transformations are triggered by ancient artifacts. That’s because this is a book about a major antagonist who defies fate.)

Fifty years ago, my entire class transmigrated into this sci-fi apocalyptic world, where the empire fights off swarms of bugs and has ten great generals. In my previous life, I was a good-for-nothing: an ordinary-looking twenty-six-year-old college student, framed by my classmates. I clawed my way up to become one of the ten generals, only to die because of an antagonist’s schemes. At last, I understood: I was nothing but a useless protagonist in a book, and the destiny I’d always been proud of was my prison.

An accident forced me to swallow an unknown alien ovary, and I was reborn fifty years in the past as the queen of that species. In this life, I’ll shatter fate itself. The protagonists here have all become women, and I’ve recruited them into my army. But there’s far more to the truth than that.

Anytime, anywhere, I am the one and only iron-blooded female commander. Until then, welcome aboard the train to heaven.
