Fans of the original 2000 sci-fi series Gate Keepers can look forward to a new anime entry, building upon the established lore of the AEGIS organization and their fight against alien Invaders. The original series, produced by Gonzo, introduced a world where ordinary citizens could open "Gates" to another dimension, granting them special powers to combat the mysterious extraterrestrial threat.

The new sequel, titled Gate Keepers 21, directly follows the events of the first season. It continues the narrative established in the spring 2000 anime, which itself was adapted from a manga of the same name. This expansion offers a chance for long-time followers of the franchise to revisit the characters and conflicts that defined the original run, further exploring the ongoing battle for Earth.

Gate Keepers 21 promises to delve deeper into the ongoing struggle, offering more action and story for those invested in the fate of the Gate Keepers and their world. The announcement comes as a welcome development for a franchise that has maintained a dedicated following since its debut.
