there was 2 (part of a series with more) the older one was adrift i think and involved training maids to fight lewd things, one was a glasses girl another was a bitch/masochist (her mom was a character too) and the third turned out to be twins.
The other was a harem game on a timer, when the game starts you already got a harem but are trying to get your memories back.
