Rasuko Ōkuma is a Japanese manga artist known for creating the series Hoshikuzu Telepath, which was adapted into an anime. She has been active in the industry since around 2016 and primarily works within the Manga Time Kirara magazine lineup published by Houbunsha, a publisher famous for its many four-panel yuri and slice-of-life series. Her work is characterized by a focus on yuri-themed four-panel comics, often noted for their visually striking and ornate art style.

Ōkuma made her debut with a short manga titled Aruji no Inuma ni! in Manga Time Kirara in September 2016. Her first serialized work was Happy Sepia, which ran in the same magazine from March to December 2017. However, this initial series was cancelled before a compiled tankōbon volume could be released, ending after a total of ten chapters. She later reflected on this experience and took it as a lesson, planning the story structure for her next major work more thoroughly from the beginning.

Her most significant and well-known work is Hoshikuzu Telepath, which began serialization in Manga Time Kirara in 2019. The series follows the story of Umika Konohoshi, a girl who struggles to communicate, and her alien classmate Yuu Akeuchi, who claims to have come to Earth to learn about human emotions. The series gained enough popularity to be adapted into an anime television series, which premiered in October 2023. The announcement of the anime adaptation in October 2022 was a pivotal moment for the creator, as she began using social media for the first time at that point, having previously been a very private person who was uncomfortable with public speaking.

In addition to her own serializations, Ōkuma has contributed to several anthology comics for other popular series. Her work appears in official anthologies for Slow Start, Laid-Back Camp, and she also contributed cover art for the second anthology of the hit series Bocchi the Rock! In 2023, a collection titled Happy Sepia: Rasuko Ōkuma Works Collection was published, which compiled her cancelled debut series Happy Sepia, her short story Aruji no Inuma ni!, and a newly drawn Hoshikuzu Telepath manga.

Beyond her artistic career, Ōkuma holds an unusual educational background for a manga creator. She studied special education at both the undergraduate and graduate levels, focusing her research on children and individuals with developmental disabilities. She has applied this real-world experience to her writing and character portrayals in her manga, and she has also worked as a student volunteer and part-time lecturer in this field. Her early influences include fellow Manga Time Kirara artists such as Cherry Arai and Akira Kokonishi, and she was inspired to read the magazine after encountering the series Hidamari Sketch.
