Youjo Senki?

 

I always love to recommend The Girl Who Ate a Death God.

Becoming the strongest or living a slow life are both objectives as well.

 

Slow life can be an objective, but for most JP novels it's not,
Slow life as an objective is for example in Trash of the Count's Family

 

So, something like Kumo Desu ga, Nani ka? (The first half at least).
There is one. Forgot the title, something like liable duke daughter.

 

+ 1 for Youjo
Else, maybe Kumo Desu ga, Nani ka? and/or Dungeons Appeared in Real Life

Just search the Japanese name on Google and no there havent been a new chapter last time I checked

 

The synopsis has an obvious typo. Calling a man a she.
Is the translation any good?

 

I think the phrase you're mentioning is the one with apostrophe mark which signs the man's thought, no ?
And about the translation, for me it falls to the "good, clear and enjoyable" category of translation I guess. Maybe try a few chapters ?
