There should be release filtering for only English releases and filtering for series genre. I think it would help the readers to find the manga that fit their taste
The MC has already met with the Demon Lord and she joins the Harem and she's the only person aside from the loli fox that wasn't brainwashed by the MC.

@kronix No, Impregnating the house spirit will add another floor, but the house spirit can't bare a HUMAN child, so when I say the MC impregnate the House spirit that means that their "Child" is the new floor.
In the novel the MC has started having sex with the house spirit around chapter 10-30...
A little bit of a spoiler in the novel he had sex so much with the house spirit and as a result the House became a Japanese castle with many upper floors! Also the mc will meet the Loli dragon and a big boob dragon soon.
