The mc was a joke character in a game reincarnated into this world using the vessel of a god. So his base stuff is broken from the start. (Like having a black card which is the highest rarity of national treasure status.)
His class is a gigolo, with skills that synergizes together to basically auto capture any woman he sees.
He porks a succubus, and doesn't die, making him her master. This gives him really high status as she is a famous high ranking adventure.
His status, class, and maybe world culture, make it so building a harem is normal/acceptable.
He unintentionally captures about 3 more women before he starts trying to do anything about his auto capture skills.
Worried about his class needs, and physical stats, the succubus decides to build a party around power lvling/protecting him, and build a harem at the same time.
This whole chapter though was built around investigating and staging a raid on the "play rooms" that they discovered thought one of the candidates. (Think of it as the capture target pre-recruitment quest.)
