The beginning will be heavily revised due to outline-related reasons.
(Occasional chuunibyou fits, but she pretends to be the heroine + a minor System element (gone very soon) + interstellar setting + mechs + more to be added)
(There may be a male lead)
Nin, a powerful figure from the apocalypse, was supposed to enjoy a wonderful retirement. But just as she was about to meet her end after mutated insects struck back, the System unexpectedly sent her to the interstellar era!
From the start, she gets hit with a major blow! Her adoptive father, who has no regard for human decency, wants to send her off to be someone's mistress! Is she supposed to put up with that?!
The powerhouse makes her move on the spot!
"You just wait! When I get back, I'm going to kick your ass!!"
Drawing on years of experience surviving, the powerhouse decides to retreat for now. Once she's recovered, she'll be back!
"Hahaha, didn't see that coming, did you? I'm back to find you already."
--
After becoming the leader of a gang, the powerhouse sees the mechs secretly transported by the gang and falls in love with them! When she learns that the only place she can learn to pilot mechs is the Joint Military Academy, she resolutely sets off for the academy!
You have to understand, wherever the powerhouse goes, she's the powerhouse!!!
