MC without motivation for anything.
Great.
She got motivated when her first name servant died, and she retaliated with as much power as she could gather on short notice. That felt satisfying, but she's back to square one: she has no clear objective, no driving force aside from a vague desire for "victory" imposed on her by her swarm.
So what now? Wait for her to be discovered so she can retaliate? Is that how the story goes, with a passive MC who doesn't know what to do until she gets attacked? No active attempt at world conquest, no thirst for adventure, no longing for her past world?
That's a bit lacking. Any NEET isekai has a more active MC than this one. Even those that actively pursue a quiet life make more effort to that end than this MC.
