At only 17 years old, Utsuru Sanada has established himself as an accomplished professional photographer. Thanks to his remarkable photographic memory, known as "Shutter Eye," he can accurately predict the three sizes of any girl and recall every detail he sees. Additionally, his martial arts skills enable him to counterattack karate moves, a desirable ability for most men. When he meets the stunningly beautiful Niko Kurihara, who harbors a dislike for men and is a martial arts expert herself, Utsuru endeavors to prove himself worthy of her trust so he can snap a photo of her.
