It's a machine translation, or it's so subpar it might as well be.
Gameplay wise, the game is essentially Welcome to the Adventurers' Inn. You go to towns, pay for mercenaries that autofight for you in battles that are basically a statcheck (You must have this much total combat power to proceed). You get drops from the dungeons that you use to give a 3 day stat boost to a stat of your pub (Facility i.e. Decor, Food, Wine) and if you get those stats above a certain value, then maybe one of the girls will stay a night at the inn where you can drug her using some of the drops from the dungeons. The girls appearing appears to be...inconsistent, as in you can far exceed the required stat and yet she doesn't appear at all, and only one can show up per night. I'm not entirely sure whether or not girls showing up requires you to clear certain floors in dungeons or just clear any dungeon, but girls tended to not show up at all until dungeon statchecks were passed. The use of the drugs appears to be odd as well, since you can choose the "sleeping pills" option yet the scene will show the girl completely awake and aware.
Honestly, not really worth the time. I can see why the game is listed as being in early access; essentially machine translated English, sounds looping when they shouldn't, images not lining up with what can be inferred from the Engrish, the music resetting after every menu option. Needs a bit more polish, and even then it's pretty much just a copy of another game that came before it with less sprite art.
