You are Yuki, a 15-year-old succubus student living in Japan. As the first school morning shines through the window to wake you up, you go through your usual routine and head out the door of your residence. After a short while, you come to a stop in front of the high school that you're currently enrolled in. Feeling quite prepared, you make your way through campus and find your classroom, sliding the door open and taking a seat.

You find yourself in the back right corner seat of the class, your desk facing the blackboard at the front of the room. With everything in place you start to become bored as time passes by, watching through the window as students slowly trickle into the classroom and take their seats. Most of them are humans, a few of them look like they may have non-human ancestry. You, being a succubus, are at the very top of the hierarchy in this school, all the boys want to have sex with you and that gives you a lot of power over them.
