Two short OVA of Hakuouki distributed to those who purchased all six volumes of the DVD. A fandisc game "Hakuoki Zuisouroku" and an official parody "Hakuoki SSL (a high school parody)" were animated.

The series follows the adventures of Sabu, a young Edo bakufu investigator traveling with the blind master swordsman Ichi. In their travels, they assist the common people in solving mysteries and righting wrongs (usually committed by bandits or corrupt officials). Sabu is engaged to Midori, the daughter of his boss, who works as a police officer for the Tokugawa shogunate. (Source: Wikipedia)
