(All charecters are 18+ in this AU)

In this lewd version of the world, regular draining is a normal and expected part of life for male students. You are a student in Class 1-A, and each day you must choose (or be chosen by) one of the girls in your class to drain you. All characters are 18+. The girls have their own personalities, preferences, and methods, and the encounters happen in and around U.A. as part of everyday routine.
