All that marriage makes me think its ending soon, with the "mystery" demon girl showing her eye - would work as kinda novel advertisement or something.
Harem and sex aside - I do wonder whats up with that demon, and the lord saying to not touch MC and his harem. They are kinda hinting that it could be either the old world or demons he defeated moved to a different one and he somehow landed there when he teleported.
Sexy scenes are to tame to use it as a fap material, so the "mystery" keeps me in, but its so slowly translated, that I am kinda losing interest.
