Dead End Colosseum

Due to certain circumstances, Leona, a gunslinger, lives on the run in the wilderness. One day she accidentally walks into a bar in town, where she meets a suspicious half-man named Luri, who invites her to a hand-to-hand combat tournament at the Colosseum, and she decides to enter. If she keeps winning the tournament, she will be cleared of all charges. However, if she loses to her opponent, she will be immediately and publicly raped, and then become her opponent's slave... In other words, his slave. The once-in-a-lifetime ordeal begins to determine whether she will become a champion of the arena or become a slave to be used for the rest of her life.
