I skimmed through some of the past chapters. The dark haired lady is a goddess who reincarnated the mc. This world uses game mechanics from a game he played, and he starts off OP with skills he had in the game. His goal is to get a harem.
First harem girl is the dark elf, who is actually a follower from his game. He buys her from slave shop.
2nd harem girl is the bunny girl. MC tried to buy her at a slave auction, but a noble either won the bid or messed with MC, so MC killed the noble and took the bunny girl before noble could rape her.
3rd harem girl is the daughter of a noble. The butler tried to kill their family but mc rescues them and the noble declares loyalty. The father might have been turned into a zombie follower?
Then MC decides he's going to build his own kingdom or dungeon, and have the goddess be the designated deity. Starts gathering the goddeses' believers, who are refugees from persecution by believers of another god. MC summons the goddess to appear in the world, forgot for what purpose. The rival god appears with an army. His army fights the 3 girls, while MC fights the god. And this chapter concludes the fights.
Axe gonna give it to ya
