Saito Misaki (Sakura Momo) has a bad attitude in class and is often forced to take supplementary video lessons. Misaki receives a disc for supplementary lessons from her homeroom teacher today. However, the teaching materials she was given... "Introduction Video". After school, the homeroom teacher quietly sneaks into the video self-study room. Misaki has been set up with many traps for a long time and is in the middle of her training. Everything is to get her homeroom teacher's ideal "raw Onaho".
