^Ryoko

Ryoko draws her power from three stones one around her neck and one on each wrist. Ryoko is a demon who until the first episode, Ryoko Resurrected, was imprisoned, by Yosho, in a cave just outside the Masaki Shrine. She was released by Tenchi who had gone into the cave after his grandfather had told him not to. Even after all those years Ryoko was still angry at Yosho and she decided to take revenge on the first person that she saw.....too bad for Tenchi. Fortunately her anger was only temporary. She only partially destroyed Tenchi's school before she stopped.

Ryoko is the protagonist in this series. She is an Oni, an ancient Japanese devil. She was created by Washu by using a simple life form called Mass and from one of Washu's egg cells. Because of this Washu considers Ryoko as more of a daughter rather than an invention. When Zero, sent by Dr. Clay, copied Ryoko she absorbed some of her memories. After Zero allowed her emotions to surface, Washu combined Zero and Ryoko. The result was Ryoko with more obvious emotions. Ryoko's chief rival for the affections of Tenchi is Princess Ayeka. Ayeka is the crowned princess of Jurai and has the mannerisms and powers that come with her position. While Ryoko is outgoing and brash, Ayeka is more withdrawn and proper.

Little is known about Ryoko's past before her battle with Yosho. Before and during the battle Ryoko was under the control of Kagato. He took over her mind after imprisoning Washu and taking Soja. Kagato used Ryoko to lead the only successful attack on Jurai. The power in her gems is so similar to that of Jurai's trees that she managed to slip by the Jurain border. During her attack on Jurai she shot down a ship that crashed into a building. Sasami was in that building and fell to her death. Kagato sent Ryoko there to find Tsunami and capture her. She could not find Tsunami and was forced to retreat. Yosho pursued her and eventually caught her on Earth.

After that she spent 700 years in the cave near the Masaki shrine. While trapped in the shine she created a pseudo-gem which she used to fight Tenchi with. That gem was incomplete when Tenchi found her. Tenchi later destroyed it during their fight. While Tenchi was growing up she watched over him and fell in love with him when he got older.
