Hakubo revolves around the daily life of Sachi Koyama, a high school violinist with promising talent. Although Sachi is content with her school life and retains friends within the music club, her favorite pastime is appreciating the scenery around her neighborhood in Iwaki, Fukushima while walking to her bus stop alone. However, during one of Sachi's after-school walks, she has an unexpected meeting with Yuusuke Kijinami, a boy whom she often notices on her bus ride home.

This chance encounter brings together these two souls who yearn to cherish the present, knowing full well how easily it can all slip away.

After diving for an ancient sword in the waters where the battle of Dan-no-ura was fought and the Heike clan fell, Tomona loses both his sight and his father. Left with few options other than learning to play the biwa, Tomona gains enough skill to join a prestigious troupe of storytelling performers and takes the name Tomoichi. Soon after, Tomoichi meets a strange person who finds joy in terrorizing others with his deformed appearance, but is surprised when the sightless storyteller treats him as an equal. The pair become fast friends and begin performing together after the stranger—who chooses the name Inu-Ou—discovers that he is able to hear spirits telling forgotten tales of the Heike clan. Tomoichi changes his name again to Tomoari and uses his music to promote Inu-Ou's underground dance performances, achieving incredible popularity among the masses. However, the brazen and unconventional style they develop challenges traditions that the shogunate values deeply. As the pair's fame continues to increase, they must contend with the forces of tradition that control the society around them.
