Based on the erotic game by Pin-Point. 
 
The Kingdom of Elstein... A flourishing land with a history spanning over 1000 years. This grand nation rules over half of the continent. Noble born first princess to the Elstein royalty, Elize, loves her subjects and likewise, in return, is loved back. With Anna, her guardian knightess and childhood friend the two were living happy peaceful lives... 
 
However, Elize had a niggling worry at the back of her head. That was, that there was a discrepancy between the Elize which her citizens desired and Elize's TRUE inner self. You see, on the inside, Elize is a timid, mentally fragile girl, with a over active, anxiety inducing sense of self consciousness. 
 
This gap... between ideal and reality, naturally causes her stress and slowly but surely, the desire to show her inner self grows stronger... 
 
At first, she was satisfied with just walking around naked. But she craves for more thrill, more stimulation, more pleasure... 
 
Her desire for exhibitionist pleasures know no bounds and stirring up a storm of depravity, her best friend and the kingdom itself, is drawn into a whirlpool of salacious self destruction... 
 
A vulgar and exhibitionist themed story featuring a once pure princess, her proud knightess and unlimited levels of corruptive lewdity in a medieval fantasy setting!
