Based on a laidback farming fantasy light novel series written by Kinosuke Naito and illustrated by Yasumo. It has been published online via the user-generated novel publishing website Shosetsuka ni Narou since December 2016. It was later acquired by Enterbrain, who has released sixteen volumes since October 2017.
It's omitted when Ru and Tia are afraid of their husband's libido and try running away at night. Can't make it seem like he's a rapist; that won't fly on TV.
Isekai Nonbiri Nouka was released on Blu-ray and DVD in two volumes from April 19, 2023, to May 24, 2023.
Later in the story, Hiraku is quite unfortunately forced to breed with the female elves; since all the males are stubborn jerks who refuse to move to his village.
