Ataru's mother, often referred to simply as Mrs. Moroboshi, is a supporting character in Urusei Yatsura. She is the mother of the main protagonist Ataru Moroboshi and the wife of Ataru's father. The family lives in a typical lower-middle-class household in the town of Tomobiki. Mrs. Moroboshi is depicted as a standard housewife whose life is centered on managing the home and coping with the constant chaos brought about by her son and the various alien and supernatural beings that surround him. Her personality is defined by a sense of weary exasperation and a desire for normalcy, which is almost never achieved. She frequently laments her son's troublesome behavior and the havoc it causes, often worrying about how the neighbors perceive her family. Her motivations are largely grounded in maintaining a semblance of domestic order and dealing with the daily disruptions that stem from Ataru's lecherous antics and the presence of Lum, the alien who believes she is Ataru's wife. In the story, she functions as a comedic anchor to the ordinary world, reacting with understandable frustration to the extraordinary events that unfold around her. Her key relationships are with her husband, with whom she shares a common, sometimes rocky, domestic partnership, and with her son Ataru, whom she often scolds but occasionally shows a hint of grudging admiration for his resilience. She also interacts with Lum, whom she accepts as a live-in member of the household, and Lum sometimes helps her with housework. Over the course of the series, Mrs. Moroboshi experiences little dramatic development, remaining a static figure whose role is to provide a grounded, adult perspective on the absurdity of her son's life. She has no special abilities or powers, being an ordinary human without any supernatural traits. Her primary function is to highlight the contrast between her mundane concerns and the fantastical situations that regularly invade her home.
