The super sentai group Kankaku Senshi Gokan Five have protected the earth but with the start of a more peaceful period, the members have drifted apart. Gokan Red and Gokan Blue run a bar with an airsoft shooting range, which takes up most of their time. But Red still feels its their responsibility to be prepared and he tries to find a replacement for Gokan Peach, who died in battle 10 years ago. He has high hopes for Momoka, a 17-year old school girl, who just wanted a part-time job a the bar and isn't yet sure about joining the Gokan Five.
