Ouka has very long black hair that has square bangs and blue eyes. She wears a pink kimono with dark purple ends, black arm guards with dark purple wraps on her forearms and purple and white cloth on her upper arms.

Ouka is a quiet and cold woman who keeps to herself; as such, not much is known about her besides the fact that she is Muneyuki Manyuu's bodyguard. Nonetheless, she occasionally shows a more compassionate side.

A Manyu assassin and Muneyuki's bodyguard who is sent by the Manyuu to chase after Chifusa. She is cold and ruthless, showing no mercy against any foes. She is an incredibly skilled swordswoman, her skills matching and possibly even surpasing Chifusa's. She was the first person that Chifusa used the Breast Flow technique on, accidentally stealing her breasts during a duel when both of them were young. After she lost her breasts to Chifusa, Ouka endured the harsh lifestyle of a flast-chested commoner until Muneyuki employed her, ignoring her lack of social position due to her small breasts. It is implied that Ouka is in love with Muneyuki because of this kindness.
