Kanrinin - Reitetsu Reijou wa Gakuen Ryou ni Shizumu

There is a man called the "Manager." Making a living by doing businesses in the underworld, he is also known by his true identity "Dark Shipper." At the request of his clients, he provides a "thorough management" to their targets, after making them into an "obedient product", they are shipped to his clients.

One such job takes him to the prestigious school "Shuchi'in Acedemy", a gathering place for the people who are expected to play major roles in the future in various fields such as economy, politics, and entertainment. A request arrives for the "production" of a girl who attends this school, the daughter of the Himemo Group, Himeno Satsuki.
