It's a workday from hell for officer Leona Ozaki. The jealous traffic-meter girls are determined to get between her and handsome chief-of-staff Sakura; her uptight subordinate Shinozaki has mysteriously disappeared into the Traffic Control Division; and sky pirate Urushi-Maru is flying free above the city. Leona has neither the time nor the patience for this -- but what she does have are three HEAT rounds, and if she aims them just right she can end all of her troubles!
