Yuriu Haigamine is a character from the anime Killed Again, Mr. Detective?. She is an up-and-coming actress whose involvement in the story introduces elements related to performance and deception, themes that resonate with the series' central premise of a detective who repeatedly dies and returns to life.

Physically, Yuriu is depicted as a teenage girl with brown hair that reaches her waist and orange eyes. Her design typically includes twintails, and she wears a school uniform complemented by a cardigan and a neckerchief. She is voiced by voice actress Yoshino Aoyama.

In the narrative, Yuriu serves as a supporting character whose profession as a rising star in the acting world adds a layer of complexity to the mysteries the main characters investigate. Her role as an actress is noted to create a parallel with the protagonist Sakuya Outsuki, whose own life is a series of performative deaths and resurrections, suggesting her character may be involved in cases where illusion and reality are blurred. The specifics of her personality, personal motivations, and key relationships are not extensively detailed in available sources, though her interactions are expected to challenge the central duo and act as a narrative pressure point within the story.
