UMI is a creator known for work in the webtoon and anime industry, primarily recognized for their role in adapting the South Korean web novel Omniscient Reader into a manhwa format. This adaptation began serialization as a webtoon in May 2020 on platforms such as Naver Webtoon, with UMI credited as the original creator or scriptwriter for the comic version, while the illustration was handled by the artist Sleepy-C. The source material, a novel by the author sing N song, was originally published in 2018, and the webtoon adaptation has been collected into multiple published volumes by studios including REDICE STUDIO.

In the context of the animated adaptation, UMI’s work on the webtoon serves as a foundational element. When a television anime adaptation of Omniscient Reader was announced in 2024, UMI was officially credited alongside the original novel author sing N song and illustrator Sleepy-C as part of the original work team. This establishes UMI’s role as a key figure in translating the narrative for a visual medium, contributing to the story’s structure and adaptation rather than the original novel’s prose.

Information regarding UMI’s broader career, personal background, or a portfolio of other notable original works outside of the Omniscient Reader project is not well-documented in widely available sources. The professional identity is primarily defined by their credited contribution as the writer or original creator for the webtoon adaptation of this specific series, which has become a significant title in the webtoon landscape due to its readership and subsequent adaptation into other media, including film and animation.
