Kanji Himuro was simply walking around the city of Tokyo on an errand for his mother, when he spots a hot I-Cup Black/Pink Haired girl wearing only a blue hoodie and some sneakers. When she stops on top of some air vents on the sidewalk and the air begins to shoot out, he shocked to find that the girl is totally naked under the hoodie and is dancing and rapping like a professional stripper/rapper. Upon reaching his home, Kanji is still flabbergasted as to what he just saw earlier. But when he goes to school the next day and discovers a set of headphones that the girl was wearing belonging to one of his classmates, his world gets rocked in more ways than one!
