The Urusei Yatsura manga series features a large ensemble cast of characters created by Rumiko Takahashi. It tells the story of Japanese teenager Ataru Moroboshi, and the alien Lum, who believes she is Ataru's wife after he accidentally proposes to her. The series contains many other characters, whose unusual characteristics and eccentric personalities drive most of the stories. In addition to extraterrestrials, it includes many appearances from figures in Japanese mythology and history. Main characters Ataru Moroboshi is the main protagonist of the series. A 17-year-old lazy student at Tomobiki High School, Class 2–4, Ataru suffers from an incredible amount of bad luck, having been born on Friday the 13th, during a major earthquake, and Butsumetsu, the unluckiest day of the Buddhist calendar. Thanks to this lack of good fortune, his triumph in the game of tag that saves Earth from an Oni invasion turns into a defeat for him. His victory statement, intended to confirm his girlfriend Shinobu's promise to marry him if he won, is misinterpreted by Lum to be a marriage proposal. Much to his chagrin, she accepts. Lum's arrival strains Ataru's relationship with Shinobu. But Ataru has always been very lecherous. His main goal in life is to live in the center of a harem composed of exotic and beautiful women, including Lum and most of her alien friends. Usually, he just walks up to a woman he has never met before and asks for her name, phone number, and address. If Lum, who now views him as her husband, should witness these usually futile flirting efforts, she regularly zaps him with massive quantities of electricity, but they do nothing to slow him down. Ataru may come across as academically unaccomplished and unwilling to make an effort, but he is actually quite intelligent, able to manipulate situations to his advantage. Though he often tries to escape from Lum and openly flirts with other women, he begins to truly love Lum, while steadfastily refusing to admit it. Lum is the female protagonist of the series. She is a beautiful Oni (translated in English as "ogre") alien who is capable of flying and generating electrical shocks and even lightning (resembling the thunder god Raijin). She is usually seen wearing her signature outfit of a tiger-striped bikini and knee-high go-go boots. As an alien she has access to many bizarre gadgets whose use she does not always understand completely,
