Anime.
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. It was directed by Yoshikata Nitta, with character designs by Kenzō Koizumi and art direction by Geki Katsumata. Series creator Takeshi Shudo noted in a column for "Web Animation Magazine" that the anime adaptation was initially planned to be 52 episodes, before being cut down to a 12 episode season, and then cut again to its final 6 episode OVA.
A soundtrack for the anime series was released on October 23, 1992, two months prior to the OVA series. The soundtrack was performed by guitarist Jinmo, with vocals for the opening theme song, "Ocean", performed by Azumi Inoue.
Video game.
A role-playing video game based on the series was first released on the Super Famicom in 1995 exclusive to Japan. The game was developed and published by Tokuma Shoten. "Eternal Filena" was published late into the Super Famicom's life, having initially been planned to release alongside the OVA, however delays pushed the game back two years from the OVA's release.
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. Some aspects from the light novels were not reflected in the game, such as the characters Baraba, Razzle or Tess not making appearances or periods of time when Filena and Lila were parted, instead having Lila as the only permanent party member among the other members who join and leave through the game. 
The gameplay is typical of role-playing video games of its time, using a turn-based battle system with random encounters with monsters to gain experience and level up. Characters can equip up to three weapons and switch between them. Weapons have different abilities and a character can perform a technique at the cost of ability points.
Reception.
The series was popular enough to place in "Animage" polls for readers' all-time-favorite series as late as 1999.
On release, "Famicom Tsūshin" scored the game a 23 out of 40. 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. Ciolek surmised that the game "rarely lives up to its genre-defying promise, but there's still something intriguing there."
