(OVA) sequel, '' Gate Keepers 21'', was released in 2002. The main characters in the OVA sequel were the next generation of Gate Keepers. All ''Gate Keepers'' series follow the same basic premise and share most of their characters, with some major discrepancies (mainly involving the character Reiji Kageyama). A character from the game, Francine Allumage is completely absent from the anime. Another character from the game Misao Sakamori, was replaced in the anime with the new original character Megumi Kurogane (though Misao does make a guest appearance towards the end of the anime).

. These superpowers are the only weapons that have any effect on Invaders. Although A.E.G.I.S. has branches around the world, the series focuses on the Far East division in Japan. The headquarters of the Far East branch of A.E.G.I.S. lies beneath Tategami High School, a facade created by the organization to mask the active recruitment of new Gate Keepers. Since many of the candidates were High School students, the location allowed the agents to be enrolled in school and be available for a mission at a moment's notice.
