In the peaceful little town of Sakuranomori, a group of young friends are about to bid farewell to one of their own. Due to his parents’ business plans, Sana Hidaka has to move away from his quiet childhood home to the boisterous city of Tokyo. Though it pains him, he must say goodbye to his precious friends—the kind-hearted Aoi Oribe, the spunky Wakatsuki twins, Shuri and Shuusuke, and the cheerful and upbeat Nanaka Yatsushiro. But even though he is reluctant to leave them behind, he believes that no matter how far apart they are, they will always cherish the memories of their friendship. Five years later, Sana, now a 16-year-old high school student, returns to his hometown with the hope of restoring his old life. However, he quickly realizes that although his town may not have changed drastically, the friends he left behind are not who they used to be. Unsettling shadows loom over Sakuranomori as his friends hold new secrets and bear burdens that threaten the bonds they once shared.

After witnessing the death of her family at the hands of bandits, Unchou Kan'u has devoted her life to protecting the innocent by exterminating any group of bandits she comes across. Over time, Kan'u's deeds become famous throughout the land—even if she herself remains unknown. During her travels, she runs across a young girl, Chouhi Yokutoku, whose parents suffered a similar fate as Kan'u's. Finding companionship through their similar pasts, the two girls take a vow of sisterhood and continue to wander the land, determined to bring peace to wherever their journey takes them.

During Kan'u and Chouhi's journey, they meet and travel with several people who are sympathetic to their cause, such as the noble Chouun Shiryuu, the headstrong Bachou Mouki, and the calculating Shokatsuryou Koumei. From problems with local lords to groups of ravaging bandits, Kan'u and her friends do what they can to make life a little easier for those in need, wherever they may be.
