Castle Fantasia

You are a knight named Varu who has a very beautiful girlfriend and is very happy with her. However, one day their kingdom get involved in a war, and the girl's parents die in it. After some time, an unknown religious organization appears in the city. Varu's girlfriend is in such a grief after the death of her parents, that she decides the world has nothing to offer to her, joins the adepts of the new religion, and leaves the city. Varu becomes very depressed after this separation, but when he learns the religious group which took away his girlfriend became an evil cult that kidnaps girls and seeks resurrection of demons. But even more awful is the fact his ex-girlfriend is now the leader of this cult...

"Castle Fantasia" is a strategy RPG in the same vein as Farland, but with addition of erotic elements. You navigate your party on battle screens in turn-based mode (unlike Farland games, your turns depend on the agility of the character, and there are no separate rounds for your and enemies' party). When you kill an enemy, he drops a heart. Collecting those hearts allow you to increase your characters' parameters. You get different endings depending on which one of your characters has collected most hearts during the game.
