This spring, Mikuru came to her alma mater as a student teacher. She had grown close to Meguro, another student teacher, and the two shared a strong bond. One day, she was asked by the vice principal to visit the home of a reclusive student named Dai. There, she was ambushed by a malicious family and their accomplices, who exposed her defenseless body in front of Meguro. Helpless, Mikuru was violated, filmed, and then repeatedly raped every day, slowly breaking her mind and body beyond repair.
