The story takes place in a re-imagined version of the Edo era of Japan just ten years after the unification of Japan. The story is about the daughter of Date Masamune who runs away from home and meets with a young ronin samurai and has him chased by her pursuers in order to run away.
After Tokugawa Ieyasu unified Japan in 1600, the Warring States era had finally ended after a century of war and the remnants of the Western Army of the Battle of Sekigahara were spread out across the land while the feudal lords who sided with them were stripped of their statuses. In 1610, the princess of the Date Clan, Iroha ran away from home and had disappeared from Sendai, believing that it was a kidnapping, her father, Masamune, sent out soldiers in pursuit to find her and kill anyone who could be the kidnapper. While running away from her pursuers, Iroha stumbled upon a young man by the name of Shiraii Kentaro who was travelling with a sword and had him chased instead. Now believed to be Iroha's kidnapper, Kentaro must run away from the people chasing them and find who the girl being chased is.

After becoming a ronin samurai, he has only trained and searched for jobs to do as he travelled across Japan, and in his travels, he has done some bodyguarding, work for the police, bounty hunting, and even stopping crime.
