Wearing a helmet and commuting to school by bicycle is proof of being a country girl. It is a brutal radical group that lusts for such naive girls. Aim for the place where they are alone and attack.

In the nature of the countryside, the reluctant voice is drowned out, and Ji Po, who aims at prey only with lust, invades Ma Ko.
