As a citizen police, Yoshiichi is just a vague life, just seeking peace. It was not until his pressure approached the limit that he realized how exciting and refreshing it was to enforce the law with a gun. At the same time, Yoshiichi met the pure convenience store girl Momo (played by Hayami Akari). In order to win the girl's favor, he tried every means to get more money...
