The story of a teenage boy called Yu, who falls for Yoko, a girl he runs into while operating for the sake of sin as an upskirt photographer in an offshoot of the porn industry. His attempts to woo her are complicated by a spot of cross-dressing - which convinces Yoko that she is lesbian - dalliances with kung-fu and crime, and a constant struggle with the guilt that's a legacy of his Catholic upbringing.
