Bind ～緊縛尋問伝説～

The content of the game can be easily deduced from its title ("Kinbaku Jinmon Densetsu" means the legend of bondage interrogation). The game contains three "episodes", unrelated to each other story-wise. The first one is set in medieval times and tells about the adventures of two female treasure hunters in an ancient tomb; the second begins with two young girls being kidnapped by a mysterious secret society; the third deals with three school girls being assaulted by a thief.
