Hakuoki - S01

Whispers of a plot to destroy the Shinsengumi by burning down their headquarters are spreading wildly. Since most of these rumors trace back to an inn in Shimabara, the Shinsengumi turn to Chizuru Yukimura for help. She goes undercover as a geisha to gather information, but the mission soon proves far more complicated than anyone expected. Meanwhile, the Shinsengumi members have mixed feelings about sending their only female colleague into danger. Aware of the risks she faces, they vow to keep her safe no matter what.
