A prequel to Hakuoki. The Shinsengumi did not begin as the Shinsengumi. When the young wanderer Ibuki Ryuunosuke first falls in with the Mibu Roushigumi — grudgingly, and entirely by accident — they are still finding their shape. This is the story of those early days in Kyoto: the bonds that formed before the history was written, and the goodbye that came when they were no longer just another group of swordsmen passing through.
