This story seems to have absolutely no idea where it wants to go.
MC seems to randomly swing between angel mode and demon for very weak reasons (Miracle cures for you, brutal death by blade or poison for you), at this point her hands are stained with far more blood shed in a far more brutal manner than virtually any other isekai MC to date. So considering that, the fact that she continues prancing around as an aloof ditz (while calling OTHER people stupid... orz) is getting quite old.
The only time she actually seems to actually think about what she's doing is when she's getting in a tight spot or feels uncomfortable. And for anyone who says that this MC has common sense... I would instead ask you all, what do the actual world residents that are accompanying her on her sight-seeing trip think of her common sense? Yeah, from their perspective, she has none.
