Hakuoki: Demon of the Fleeting Blossom

Hakuoki: Demon of the Fleeting Blossom (released as Hakuouki Portable in Japan) is an otome adventure game developed by Idea Factory. The entire series was Japan-exclusive before Aksys Games decided to work on localizing Hakuoki Portable for American audiences under a new name. The game proved successful enough in the United States for Aksys to announce that they were localizing the sequel under the name Hakuoki: Warriors of the Shinsengumi as well. It is one of the few visual novels to have an official release outside of Japan.

Story
Japan's Edo Period was drawing to a close. The shogunate, who'd held power in the country for more than 200 years found itself challenged by the imperial court and by several domains who had chaffed under shogunal rule. In the midst of this political unrest, an organization rose to prominence: The Shinsengumi. Originally formed to protect the street of Kyoto from masterless samurai, they came to represent the last tragic bastion of the honor-bound samurai culture that had defined much of Japan's history. A young woman by the name of Chizuru comes to Kyoto in search of her missing father and soon encounters danger and the Shinsengumi in quick succession. When it becomes clear the Shinsengumi are also searching for her father, Chizuru is put under their protection. But odd things are afoot in Kyoto - possibly even supernatural things.
