Urakata Hakuoki: Akatsuki no Shirabe

The third year of the Bunkyuu era. The Tokugawa shogunate is weakening, and in the capital, a pair of siblings who run a small dojo are caught in the upheaval one winter night—attacked by men with white hair and crimson eyes who should not exist. The older brother disappears protecting his sister. She picks up a sword and steps into the chaos of an era already burning, determined to find what happened to him. The men who gather around her in this disorder are unlike anyone she has ever met.
