Isshin is the son of a prestige samurai clan, whom for unknown reasons have traveled into Edo with his most trusted servant, Seiichirou. Believing it's best for his master, Seiichirou leaves Isshin into the care of the Edo's fire brigade team number fourty eight's "Ku Squad". Without any knowledge of firefighting, can Isshin blossom with courage and show his true samurai strength?
