A very old visual novel with minimal plot. Aya, A girl that just recently turned 18 gets taken into slavery over her parents' debt and is forced to fight in a wrestling ring against other girls in her underwear. The story is really short, she only has two opponents. A girl named Honma, whose stage name is Wildcat. And a girl named Miki, whose stage name is Mistress. She actually befriends both of those and pretty much becomes Honma's lover. I think that was one of my first eroge, from around the same era as X-Change. And most likely people that played X-Change 1 before it got a remake also played this.

Without "retro artstyle" tag they might differ quite a lot from how they originally looked.
