Taking place in a fantasy world, the game follows prince Gerard Himerce, joined by the half-human fairy Elaine Shee and the exiled dragon duke Galahad, seeking vengeance for destruction of his homeland against the Zar Harc empire led by the King of Darkness and prevent him from resurrecting an ancient demon.

Through the journey, players explore and search for items to progress and power-ups, fighting enemies and bosses, and gaining experience points to increase their character's maximum health and level.

Joined by the half-human fairy Elaine, last survivor of the Shee clan, and Galahad, an exiled duke from the land of the dragons, Gerard goes on a journey to prevent his older half-brother Albert, now the leader of Zar Harc, the King of Darkness, from reviving an ancient demon.

Along the way, they are guided by a mysterious spirit known as the Warrior of Fire, who tells them to seek three keys that have been scattered around the world in order to enter the floating citadel of Gaiapolis.

Along the way, players can pick up items such as food to replenish health, weapon and equipment upgrades, eggs that carry guardian beasts inside, jewels with magic powers and treasures that give out more points.

[11][12] Both the plot and story were written by Tadasu "Tadasuke" Kitae, who also served as co-programmer alongside Hideo "Hides" Shiozaki and Tomohiro "Tom" Ishimoto.

[21] Konami Kukeiha Club members Satoko "Fairy" Miyawaki, Seiichi "Prophet" Fukami and Yuji Takenouchi (under the alias "Technouchi") produced the music and sound respectively.

[24] Fukami claimed that development proved to be long and it was difficult managing the amount of compositions he was working on, losing track of details when approaching the range of 40 songs in total.

[24] When having a writer's block, Miyawaki would look at the drawings and songs of her co-workers, while she also commented that Kenichiro Fukui would request their help with tracks for Lethal Enforcers, when Takenouichi was occasionally humming a tune when thinking over new ideas during lunchtime.

[27] The release was supplemented by an album containing the game's original soundtrack and other Konami titles was distributed in Japan by King Records on August 21, featuring two arranged tracks by Seiichi Fukami that were later included as part of a compilation album published in 1998,[22][28] as well as a one-shot manga adaptation in the August 1993 issue of Shinseisha's Comic Gamest manga anthology written and illustrated by Shūjirō Hamakawa.

[7] It remains exclusive to arcades and has not received an official home conversion, though an unlicensed port for Famicom was developed and published by the Taiwanese company Sachen in 1994.

French magazine Joypad noted its mixture of action and adventure genres, stating that the playstyle is more reserved for consoles, and found the addition of a password system innovative within the arcade scene.

[35] Gamest's five reviewers gave a positive remark to the audiovisual presentation but criticized its story and direction for being uninteresting, while noting that battling enemies by performing the same fighting actions was monotonous.

They felt that the game challenged the notion that the action role-playing genre was not suitable for arcades, recommending it for players that enjoyed titles like Cadash and Dark Seal.

Sega-16's Ken Horowitz highly commended its Dungeons & Dragons-esque hack and slash gameplay, character designs and colorful visuals but expressed disappointment towards the lack of a home release, specifically for the 32X.
