A character in the Various Tenchi Muyo Cartoons, fanfics, mangas, movies and hentais. Ryoko is a green haired demoness who was created by Washu's egg and some Masu (in the OAV). Supposedly an evil space pirate, shes not actually evil, however under the force of Kagato she attacked Jurai and quite a few other places for approximately 2300 years, before finally being tracked down by Yosho and being imprisoned for 700 years before being eventually let out by Yosho's Grandson Tenchi, (whom she is hopelessly attracted to.) Although she is over 3000 years old, the net result of her various imprisonments has been that emotionally and intellectually speaking shes still 17 years old. According to the Manga (which is in the same universe as the OAV), she has the latent power to generate the Light Hawk Wings, suggesting she happens to be somewhat of Jurai royal descent because of the gems on her wrist. She also eventually becomes Tenchi's daughters (Mayuka) god-mother.
