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. After offering to help Kijinami find a perfect view of the evening landscape—the subject of his next painting for his art club's exhibition—the two forge a bond over their mutual admiration of the beautiful scenery bathed in sunset. This chance encounter brings together these two souls who yearn to cherish the present, knowing full well how easily it can all slip away.

Much to her horror, the ronin are slain right in front of her eyes by white-haired, red-eyed samurai, only to be quickly disposed of by three men from the Shinsengumi—a special police force who serve the shogun.

Upon learning that her missing father is also the same man they are searching for, the chief allows her to stay in their care while they look for his whereabouts. While working as an assistant for second-in-command Toshizou Hijikata, Chizuru slowly discovers just how connected the troubling political environment of Kyoto and the demonic-looking white-haired samurai are to her.
