After Class Lesson

Ryuji Shibui works as a teacher at a prestigious all-girls academy, where the students come from wealthy and influential families. His unattractive appearance and openly perverted demeanor make him an object of scorn and disgust among the young women he is supposed to educate. Despite their contempt, Ryuji holds a position of authority, which he begins to corrupt after a fateful discovery.

He learns of a deeply personal secret belonging to Ayumi Tenkawa, one of his pupils. Using this knowledge as leverage, he coerces and rapes her, crossing a line from which there is no return. The experience unleashes his darkest impulses, and he methodically turns his attention to other students. By investigating their lives, he uncovers hidden weaknesses, private shames, or compromising situations, which he then exploits to force sexual compliance, transforming the school into a hunting ground for his escalating depravity.
