From a rookie female soldier being lost memory, you incidentally become "The Chosen One" and have to protect the world.

After a mysterious accident, you are forced to move close to your mother's home. This new place holds many secrets and coincidences do not exist in this town.​

You play as Ashley Vorontsova, a strange girl with a noble/aristocratic past. With no friends, starting her first year at college and tired of living in a large dilapidated castle left to her by her grandparents that fled to America during the Soviet era, she mostly keeps to herself. Her father, once a successful businessman and fed up with his wife's daily secretive nightly outings left the American dream for the countryside back in his homeland, hitting the bottle hard and trying to pay off his never ending debts and annual property costs in the US, to try to give his daughter the life he never had. Her mother that left the family life in search of something more fulfilling and luxurious went in search of a more "spiritual" journey. Leaving their 18 year old daughter to fend for herself in Capitalist America with the ever increasing wealth gap. Until a dorky boy
shows up on her doorstep one day..

The game focuses on a school that's slightly strange at first glance. However, after spending some time there, anyone will realise that it's a lot more than just "strange".

Basically, OB is a Reverse Trainer in which the player is being trained to become the perfect submissive secretary following an unfortunate incident in his/her previous life. It follows my usual theme of transformation and submission, which have been missing in DT3, along with a variety of npcs to interact with.
