The protagonist, Yukimura Chizuru, is the daughter of a doctor who works in Edo. The father leaves Edo to work as a volunteer doctor and moves to Kyoto without his daughter. As time passes by, Chizuru starts worrying about losing contact with her father, so she decides to go to Kyoto in search of him. On the way, Chizuru is attacked by few criminals and witnesses a fight between an oni and the Shinsengumi. Taking her into custody and saving her, the Shinsengumi debate on what to do with Chizuru when they discover that she is the daughter of the doctor they are also looking for. So they decide to become Chizuru's protectors and help her look for her father(the doctor). Lots of events happen while she stays with the Shinsengumi, as they discover mysterious secrets and also fight against the Bakumatsu group. The story is overall romantic with a historical and political background.

Based on a popular otome game, Hakuouki follows Chizuru and the Shinsengumi in an alternate reality. Chizuru travels to Kyoto in search of her missing father but, after being involved in an incident, she ends up being taken in by the Shinsengumi where she meets the members including the famous Hijikata Toshizou and Okita Souji. Chizuru’s father was conducting government research for strengthening the Shinsengumi and developed the ochimizu. The ochimizu is a formula that gives demon-like strength and regeneration effects, but once taken, the user experiences extreme pain and eventually turns into a blood-thirsty monster.
