Welcome to Rattangrove Academy!

The finest finishing school in Hartia, featuring strict chastity, enforced denial, regular corporal punishment - and that's if you behave! At least those are the rules for Locked girls, and Emily is most certainly, and securely, locked until she can afford to buy back her key.

That's why she's at Rattangrove after all; there is no shorter road to earning her freedom and a way out of her tiny steel cage than to stick through all four years and graduate.

It sounds simple, but the school's standards are high, the list of rules lengthy, and the punishments severe. Four years can be a very long, extremely frustrating time, even for a very well-behaved student, and the school offers so many temptations to break the Golden Rule: Good Girls Don't Cum.

Join Emily, her roommate Madison, and the rebellious girls of the Red Cage Society for Emily's fun, frustrating, and often red-bottomed freshman year at Rattangrove Academy.
