Stuck in a Dreadful Mission

Kagura, a member of the Harusame, was given a special task by the admiral to spy on the Shinsengumi. First thing she knew was that she joined the group as a male; second, she was found out by a certain sadist; third, she became their entertaining prisoner; fourth, they used her to foil the Harusame and the Kiheitai's plan; and fifth, lovesick puppies followed her wherever she went.
