Nanao Inusaka (犬坂 七緒) is a Bushi who fights alongside the Onis. She is a member of an unknown organization, who wants to capture the Obsidian Goddess. Nanao has a rather indifferent personality and gloomy expression. She takes the missions seriously and can be merciless on the battlefield, but wants to finish them as soon as possible, just to go home to lounge around in her room. She has also shown a slight concern towards Musashi when he was pushed into the pit by Shiro to forcefully turn him into a crystal or to lure out the Obsidian Goddess.

Orient
At age 10, best friends Musashi and Kojiro sat in excited silence as Kojiro's father spun tales of evil demons who preyed on the innocent, and the warriors who defeated them. Practicing swordplay, the two swear an oath to become the strongest in the world. But as they grow up, Kojiro turns cynical, and Musashi comes to realize that he can't turn back 150 years of demon rule on his own. He's being called a prodigy with a pickaxe, and he's almost ready to settle for a life of labor. Yet he can't shake the feeling that he still has a responsibility to act…and, soon, the injustices of his world will force his hand… [Kodansha]
