It hasn't been that much in the west, though. I actually own many otomate games, and generally they get discounted heavily after a bit. There's at least 5 on the switch right now, rereleases of code realize, piofore, collar x malice, cafe enchante, and more. Code realize i think bombed on the PS4.

The anime exist but don't really seem to be too popular, even if the games are big. Diabolik lovers, Amnesia, etc. I think the female market is too segmented; female fans like shonen sports anime, boys love manga, traditional shoujo, yuri, and otome content.
