Hakuoki ~Demon of the Fleeting Blossom~ A Memory of Snow Flowers
Taking place between episodes 8 and 9 of the first season of Hakuoki, Chizuru goes on an undercover mission in Shimabara for the Shinsegumi. Dressing as a geisha, each episode tells the story of the undercover mission through the point of view of each captain. But it isn't just the rival clans the Shinsengumi need to worry about. It's the demons that keep popping up with the intent to kill anyone in their path that makes this Hakuoki installment worth watching!
