In the sleepy town of Medaka-ga-hama, eighteen-year-old Daigo has just passed the near-impossible exam to enter the brotherhood of firefighters. Excited by this accomplishment, Daigo is more excited by his beautiful former teacher, Ms. Ochiai, and the possibility that his new uniform will impress her!
Even in the quiet Tokyo suburb (they say that the "M" in "Fire Company M" doesn't stand for the name of the town but "monotonous"), disaster can strike! A fire breaks out in the high school, and Daigo is recklessly fearless! Can this undisciplined rookie be whipped into shape?
