Looking for something like where instead of emperors and princes, the rulers of society are females instead of males. Seems interesting, like where they are strogner then men as well. Male MC is prefered, and Modern setting is fine too Harem is fine, so is OP chars but no yaoi
Hmm Claymore ( manga) , otome game Sekai is though for mobs , World end Harem ( manga ) , . These Come to my mind though they are not totally what u asked for.
The World of Otome Games is Tough For Mobs MC reincarnates to fantasy setting where matriarchy is a thing. A total gender flip from males trying to score a fiancee by working hard etc, male 'maids', everything.
World of Women on Scribblehub is all about that (I don't know if there are any action scenes though).
