Seina is unfortunate, so bad that he is kidnapped instead of his senpai Tenchi when he comes across a recruiter hunting for him. When he is compelled to join the Galaxy Police, his luck begins to change. He is given his own decoy to attract out pirates because he is a natural at randomly hopping near pirates. His good fortune leads him to four ladies who have a propensity of canceling out his bad luck and changing it into good. With this good fortune, they are able to destroy the Barta pirates by piloting the most powerful ships in the Tenchi Universe. The only question now is whether the sultry Kaunaq, a former model turned GXP officer, the stalwart Kiriko, who has known Seina for years, or the intriguing Ryoko, a former pirate named after the mythical one, will be the ones to save her.
