Gate Keepers 21 (ゲートキーパーズ21, Gēto Kīpāzu Nijūichi?) is a six-part sequel OVA series to the Gate Keepers animated TV series and has a darker and more serious plot than its predecessor. Some of the questions left unanswered in the TV series are answered in this sequel. Linking the two series are the characters Reiji Kageyama, Yukino Houjo, and the former Far Eastern AEGIS Headquarters setting, Tategami High School.

Plot[edit | edit source]

Out of the reach of the common citizen. Coupled with the decline in the values and morals of the Japanese people comes the emergence of a new type of Invader. No longer an alien entity, the Invaders can now absorb ordinary humans into their ranks.

Officially disbanded and discredited, the few remaining remnants of A.E.G.I.S have formed a clandestine network of operatives to hunt down and destroy the Invaders. The premier agent of what's left of the A.E.G.I.S Network is the antisocial Ayane who collects the crystal remains of Invader in exchange for money doled out by the mysterious Nanzo.
