 Tomboyish and energetic with a well-endowed frame, Okoi (お胡夷) embodies the popular concept of the Kunoichi (in contrast to both Akeginu and Kagerou who embody the more historically traditional version).She shares a deep bond with her older brother Saemon and is one of the few people who can make him smile.In the anime, Okoi also has a strong friendship with the normally unapproachable Gyoubu whom she often goes with to hunt wild boar in the forests surrounding Manjidani.
