Shinjuku Utagicho is one of Japan's leading entertainment districts. In Ooho Park, located in this area, young amateur girls with high-level appearance gather for the purpose of using the slang word ``coen'', and it has become a social phenomenon. This work is a collection of videos in which they negotiated, ``I want you to let me film you, even if you hide your face with a mask,'' and have sex while filming.
