Jitsu Sanjou is part of a special group of students at a private academy. The group is known for taking part in intense duels in which they send out their knights to engage in sexual combat with an opponent. Once the undisputed queen, Jitsu seeks to climb her way back to the top after being unseated by a seemingly invincible foe. To do that, she’ll need to find the perfect knight to recruit to her side.
