Ryouko Hakubi

Ryouko is known as Ryouko Hakubi, a space pirate who was defeated by Yosho nearly 700 years before her release by Tenchi. Before that, she was a slave to Kagato. Her age is at least 5,000 - although she claims to be only 2,000. She was created by Washu, using one of her egg cells as a base, so she is indirectly Washu's daughter. Washu's DNA was combined with that of amorphous creatures called the Masu to create Ryouko. She has three red gems that are the source of her full energy, which also came from Washu. True to the meaning of her nomenclature, the gem on the inside of Ryouko's left wrist allows her to summon powerful, ferocious 'demon' spirits, which let physical attacks pass right through them, while the gem on the inside of her right wrist allows her to control the summoned spirits, and the last gem, which goes on her throat, gives her full power. She also has the ability to create false gems, one that she keeps hidden in plain sight on her left ear as an earring. This false gem is not as powerful as the originals, but allow her to balance her power and abilities. False gems also last for only a limited time, while the originals have an inexhaustible supply of energy.
