Yūya Kawamura

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.

Haruna is a lively tomboy in the 5th year at elementary school. One day, while playing with Hiroyuki, a boy whom she has known for a long time, they play a game of putting their private parts together. A sex education lesson given by a new teacher, Yagi, makes Haruna suspect that she might be pregnant.
