Utsuru Sanada is a professional photographer at the age of 17. He can guess the exact three sizes of any girl, memorize anything he sees, and counterattack karate moves (most guys would want these abilities). Why? Because he has a superb photographic memory called “Shutter Eye” (shutter as in the shutter of a camera). He meets Niko Kurihara, the female protagonist, who dislikes men, is a master of martial arts, and is, of course, beautiful. Utsuru attempts to prove to Niko that he is not the guy she thinks he is so he can take a picture of her.
