Six-year-old Ataru steps on Elle's shadow during an impromptu game of shadow-tag; in Elle's culture, this is viewed as a marriage proposal. Eleven years later, Elle returns to Earth in order to marry Ataru — by which time not only had he forgotten the events of his childhood, but he was also going out with Lum. The rest of the plot focuses on Lum's attempts to prevent the marriage. The film was directed by Mamoru Oshii who was mad at the many requests that the producer made of him to alter the movie. Rumiko Takahashi considers this film her favorite and it is the most true to the original series.
Unfortunately the movie Urusei Yatsura: Only You is not yet available on HBO Max.
