Of these, I've played Kaiware and Maid-san...
Maid-san is... predictably a maid-themed nukige that happens to include swords. I couldn't fap to it, so that should say everything that needs to be said about it, since it is a nukige.
Kaiware is a kusoge. It was among a plethora of random games I played through at the time. While I do have a mild gender-swap fetish, this was one of the few games where a rather abortive effort was made to take it seriously. It failed.
