Manatsu Misakino is an AV actress who is popular for her well-shaped face and toned body. - She usually smiles brightly in front of the camera, but as she stands in front of the microphone in her pure white room, her expression is so intense that it's hard to believe that she's the same person. - She has reduced the essential elements of AV, such as direction and acting, to the bare minimum, and is only asked for ``just sex.'' - She probably understands how high the hurdle is. - One shot, no acting, no script. - The First Sex brings Manatsu Misaki back from being an AV actress to being just a woman.
