Hakuoki: Visitor from the Dark

A mysterious princess is introduced, speaking of a "storm" arising. Meanwhile, the Shisengumi have marched to the front lines, and leap into battle on their own accord. Cleaning up after an enemy sortie, Saitou finds one of the mystery men from Ikedaya (Amagiri Kyuuju) defending Satsuma Clan soldiers; Harada encounters a third powerful stranger (Shiranui Kyou) wielding a Western-style handgun; and Hijikata with Chizuru are confronted by the blond stranger (Chikage Kazama) as they race to Mt. Tennozan.
