Eternal Filena (永遠のフィレーナ, Eien no Firēna) is a fantasy light novel series written by Takeshi Shudo and illustrated by Akemi Takada, which was serialized in the Japanese anime and entertainment magazine Animage from 1984 to 1994.

Interior illustrations as well as cover artwork for the collected volumes were done by Akemi Takada, known for her work on series such as Kimagure Orange Road and Creamy Mami.

[2][3] A six-episode anime OVA series, with original character designs by Akemi Takada, was released by Tokuma Japan Communications from December 1992 through February 1993 at a rate of two 30-minute episode per month.

[14] The game's story follows that of the light novels, in which Filena journeys with Lila to free her homeland from the tyranny of the Devis Empire and discover her true lineage as Filosena's lost princess.

[20] Todd Ciolek's Anime News Network review noted that while the series began as a light novel and had an OVA adaptation, its relevance seems mostly tied to its video game released.

Of the game, Ciolek noted that it played out much like any other RPG of the Super NES era and was only set apart by its supporting cast and the lesbian subtext of Filena and Lila's relationship.
