Everything You Need to Know About Gate Keepers
#

Set in Tokyo in 1969, Gate Keepers tells the story of a world under secret attack by the “Invaders.” While the general public remains blissfully unaware, a secret organization known as A.E.G.I.S. works tirelessly to stop the invasion. The story follows Ukiya Shun, a high school student who discovers he has the ability to generate a “gate” of special power—a rare gift shared by a few others. Joining A.E.G.I.S., Ukiya strives to recruit other Gate Keepers and protect the city, all while struggling with the legacy of his late father.

If you are looking to dive into this retro sci-fi action series, you can watch the anime on Prime Video.

Is the Anime Really Finished?

If you are wondering if the story reaches a satisfying conclusion, it is important to note that the Gate Keepers experience consists of more than just the primary series. While the original anime run concluded in 2000, there is a sequel titled Gate Keepers 21 released in 2002. To get the full animated experience, you will want to ensure you watch both entries.

For those who want to explore every corner of the lore, there is also a related manga that debuted in November 1999. If you find the anime leaves you wanting more or you prefer the original source material, you can buy the Gate Keepers manga.

Who is this Anime For?

Its primary appeal lies in its themes of superpowers and secret organizations, wrapped in a unique 1960s setting.
