It does not matter whether you are an otaku or not――― Ninomae Itsuki, a boy who doesn't have any particular skill, enjoys making clichéd MAD videos. One day, after a series of coincidences, he ends up creating an "electronic drug video" which gives strong sexual arousal just by looking at it. "I wonder what will happen if I show this to that girl who looks down on me." A dark desire rises up from within him. In the end, he succeeds in showing the video to his childhood friend Akinashi Rin, and also discovers her secret hidden behind the mask of an honors student. "Let's do business using this electronic drug." Rin proposes this "business" to him. Papakatsu, yakuza, criminal gangs―― In the underworld that he should not be a part of, Itsuki finds himself swept away.
