Nagisa Shiowatari is a character who appears in the Urusei Yatsura OVA series, introduced late in the story. He is a young waiter at a seaside beach café. His father was a close friend of Ryūnosuke Fujinami's father, and the two men arranged a marriage between Nagisa and Ryūnosuke. Nagisa was raised as a girl by his father, so he looks and behaves in a feminine manner. He is deeply in love with Ryūnosuke and pursues her with great intensity. Ryūnosuke initially refuses him because she believes Nagisa is a girl and is uncomfortable with his forward advances. It is later revealed that Nagisa is a boy. He and his father had died a year before meeting Ryūnosuke; both died from overeating while trying to perfect a sea urchin shaved ice recipe for their restaurant. They wandered as ghosts until Nagisa drank the tear of a giant sea urchin, which restored his human form. Even after regaining a physical body, he retains some spiritual qualities. Nagisa is a voracious eater and a champion sumo wrestler, possessing strength that surpasses even Ryūnosuke's. His role in the story is that of a persistent suitor for Ryūnosuke, and his arrival challenges her father's expectations and complicates Ryūnosuke's life. Nagisa's motivation is to win Ryūnosuke's love and fulfill the arranged marriage. His development includes transitioning from a ghostly existence to a living one, while maintaining his determined and affectionate nature. His notable abilities include his superhuman strength and his skill in sumo wrestling.
