Techi is a student whose grades are sliding hard. Luckily, at this school, such students can avoid getting expelled by becoming the class disciplinarian. Sounds fine, right? Keep the class harmony, get some bad marks overlooked. However, it seems this position also involves sexually servicing students with good grades, and even then, there are obstructions keeping Techi from doing her "job". Can Techi fulfill her duties without fail, and avoid getting expelled!?
