There are two types of kunoichi:
-A "shimma kunoichi" is a member of the ninja family, trained for her specific role. She typically worked under a kantokusha, or a commander, who usually tried to give her the impression she was his only kunoichi. Due to their highly emotionally sensitive natures, the kunoichi needed to be carefully handled so as not to fall in love with the target or lose sight of the goals.
-A "karima kunoichi" were usually hired only for a specific job, acting as a spy within the enemies walls. These women, usually maids, mistresses, or entertainers with access to the house may be purchased for the right price.
