* TelevisionTieInNovel: ''Gatekeepers 1985'', which bridges the gap between ''Gate Keepers'' and ''Gate Keepers 21.''

** Also the shtick of the "Ooh, intense!" girl. Over the course of no less than five {{Marilyn Maneuver}}s, more is visible each time, until we see a close-up of the front followed by her winking at the camera.

* {{Expy}}: Megumi is a strange case in that she coexists with the person she is expying, Misao Sakimori. However, Megumi became a {{deconstruct|ion}}ed expy of Misao after she pulled a FaceHeelTurn later on.

* PutOnABus (Francine, who was one of the main Gatekeepers in the game, was completely omitted in the anime. Likewise Misao's role in the game was replaced with Megumi in the anime (it should be noted that the characters do have different personalities). Both Misao and Jun also played a more important role in the game and were both main characters as opposed to their brief cameos in the anime.
