This is a hardcore adult RPG with an unique battle system, light management aspects and a focus on gangbangs. All sex scenes take place within the battle screen. There are no visual novel style sex scenes in this game.

Shape Karryn and the prison the way you want to with the Edicts system! Struggle against or accept sexual advances with the Willpower and Desire system! Become more and more vulnerable to sex with the Passives system!

Karryn’s Prison is an eroge where everything Karryn has done and have happen to her will influence the context in every battle and every sexual activity. Karryn’s Edicts, Passives, and how you direct Karryn during the battle, all provide the narrative and context before, during and after the sex.
