Kanna and Sumire are teachers at a school in Tokyo. There was a student, Kaoru, who had not attended school for more than a year in the class they were in charge of. This event occurs because I worried about him and made a home visit. Kaoru was a villainous man who kidnapped women on the street, turned them into sexual acts, filmed them, and sold them on dark sites. Sumire is framed first, and Kanna is attacked by his family's poisonous fangs! ! And it was the days of the most tragic sexual hell that began.
