Miss Ze Xinyu, whose name is wonderfully ordinary, transmigrates to a fantastical otherworld!
But! She ends up with a System that's anything but fantastical?!
It's called the Mecha Girl System! It can turn her into a mecha girl, and even turn most objects into mecha girls! What a bizarre System!
"What is this supposed to be?! It doesn't fit this world at all, you know!"
"Hey, hey! Why are the companions I made from old junk so stupid?!"
"Anyone... Just give me a good woman who can follow orders normally..."
"...Why does a companion made like this have such terrifying functions..."
Forced by the System to change her name to "Tenkiu," Miss Formerly Known as Ze Xinyu discovers a new thing to complain about every day.
Anyway, to scrape together a happy life, she must fight the evil Demon King who has set his sights on this otherworld and defend freedom and peace! Super Mecha Princess Tenkiu!
