After completing her training, Misaki was assigned to be the assistant homeroom teacher of the class as a teacher. She is filled with anticipation, but she is spotted by class delinquents Maeda and Ogata. They steal her grading paper and use it as a bait to bring Misaki to her physical education warehouse and forcibly commit it.
