So far, this is acceptable. 7/10, your average rudeus-like.

It has the potential for more... if the author steps up.
See, the author hasn't screwed up in any major way yet, but that only gets you to 7 in my rating system.
To get higher, the manga needs to actually be memorable, through good characterization, worldbuilding, humor or plot.
It hasn't yet stepped out of the 'pleasant but forgettable' box.

Wow, this sprinted the isekai fail route to the "I'll introduce mayonnaise" trope in record time. Garbage.

Haaa, yeah, the MC who come in a civilisation advanced enough from past middle age but did not invent many essentials things and was just sitting on her ass.
