Caveats: Bondage, Lolicon, Rape
The happy-go-lucky and adventurous Elm must compete in the dome known as the Eroseum and fight for her yuri-lover’s freedom from debt. After entering and getting to know the compound, you can then enter the Eroseum and fight in matches where you and your opponent lose clothes as you take damage. The loser is subjected to sexual punishments while the winner gets double the prize money. This game actually has two modes of play: Loli mode, and Onee-san mode, which affects whether the combatants and characters in the game are lolis or young women.
