The protagonist, Tosatsu Koichi, is assigned as a lecturer at the St. Cadenza Nursing School, a nursing school attached to a medical university. Whether it be because of his appearance or personality, Tosatsu is disliked by the students, who call him "a person who is not very successful" and "somehow creepy". He himself thought he was being careful enough not to look suspicious to the public, but...
One day, he accidentally found a paper in the back of the university's reference room, which was... "Female Body Experiment Report: Subject:Jinguji Narumi. Written by Hirasaka Ryuji".It was a report that seemed to have been written by a student who had enrolled in this medical university in the past.
Tosatsu read it and was shocked. He felt an excitement and a strong urge that he had never felt before. "I want to try female body experiments too..." Eventually, he could no longer suppress the urge... and Tosatsu decided to throw away everything and carry out a crazy experiment.
"First, I must decide on the prey, the test subject, necessary for this experiment..." Tosatsu muttered, but in his mind, a beautiful girl had already been chosen. "Nanase Ren", a woman who combined purity and cuteness, and was one of the most beautiful women in the nursing school...
"If I'm going to do it, I've got to use the best material... and the best experiment... and the one who will defile her first... will be me!" The man took action. Betting everything he had left of his life...
