Helen Keller is credited as the original creator for the 1981 anime television special Helen Keller Monogatari: Ai to Hikari no Tenshi (The Story of Helen Keller: Angel of Love and Light). This special, which aired on May 5, 1981, was produced by TV Asahi and NOW Project, with direction by Fumio Ikeno and a screenplay by Hiroshi Kitahara. The work is a biographical drama based on Keller’s own autobiography, depicting her early life and her relationship with her teacher, Anne Sullivan.

Beyond this single credit as the original creator for this specific anime adaptation, there are no records of Helen Keller having been directly involved in the creation of manga or other anime works. Various educational and biographical manga about her life have been published, including Helen Keller: From Darkness to Light, with a script by Megumi Sugihara and art by Naoko Takase, as well as a volume in the Kadokawa Manga Gakushū Series supervised by Hiroyuki Seki and illustrated by Tenjin Umemaru. However, in these cases, Keller is the subject of the work, not a credited creator.

As a result, no recurring themes or artistic identity can be attributed to her as an anime or manga creator, nor is there evidence of a broader industry significance in this specific field. Her known credit is limited to being the original source author for a single anime adaptation of her life story.
