Hakuoki OVA: A Memory of Snow Flowers

Beauty, grace, intelligence, wit - a geisha should posses all of these and more. The coming war grows more imminent with each passing moment and Kyoto is filled with turbulence as the various factions vie for power. When rumors reach the Shinsengumi that a group of rogue warriors intend to attack their headquarters, they must investigate the situation or risk perishing before they've even begun to fight.

The only safe meeting place seems to be the Sumi Inn inside the red light district of Shimabara. It is up to Chizuru to disguise herself as a geisha and infiltrate the inn. But life as a geisha can be filled with hazards of many kinds, especially for one as beautiful as Chizuru.
