Yugi (幽戯, Yūgi?) is a fictional character in the anime Tenchi Muyo!, the main antagonist from the television series Tenchi in Tokyo. Her appearance is that of a young blonde girl with a red and black striped headdress and large spiked armor that hovers around her.
Throughout much of the series, her plans remain in shadow, and all the viewer sees of her much of the time is her watching a group of floating crystals which represent the Masaki Family, while commenting on the events of the episodes. She has three henchmen: Hotsuma, Tsugaru, and Matori, who do almost all of her work for her.
