Via ANN:
Sentai Filmworks will release the Haku?ki television anime series on bilingual DVD. The anime adapts Idea Factory's Haku?ki Shinsengumi Kitan romance adventure game from Otomate, Idea Factory's brand aimed at female players. The story of the game and its anime adaptation center around the historical Shinsengumi samurai group in Kyoto during the 19th century. Sentai Filmworks told ANN that it will release "all of Haku?ki that is out right now." The Haku?ki anime franchise includes the 12-episode Haku?ki series, the 10-episode sequel series Haku?ki Hekketsu-roku, and the 6-episode Haku?ki Sekkaroku OVA series (the sixth episode will ship this June). The franchise also includes an upcoming prequel television anime series that will premiere this summer and two upcoming films that will premiere in 2013.
So looks like they'll be releasing all of it! Nice! I wonder if the game coming out helped pushed them towards localizing it?
