Platform: PC
Publisher: Konbuni
Game: Hanafuda-style card game
Difficulty: 3
Nudity: 4

This is a weird sort of modification of koi koi hanafuda using a set of cards that, instead of flowers, portrays crystals, elemental creatures, elves and adventurers. The premise here is that you select a girl from a set of Final Fantasy XI characters, and meet her in a dungeon where you play against her. As you complete hands, the points your hand is worth is divided based on the elements that were present in your winning hand, and these points deal damage to certain articles of clothing which vanish off the girl if you destroy them. Stripping the girls leads to lengthy sex scenes. The game can be pretty difficult since the girls usually get fairly lucky, and are at an advantage in terms of what they can lose before being defeated versus you who will get game over if only one piece of your clothing is destroyed. There was a sequel to this game as well.
