GateKeepers: Volume 6 - Discovery!

Spitzilla Attacks!

Megumi's insults force Reiko to face her own incompetence, so Reiko attempts to improve by emulating each of the other Gate Keeper's training methods. Even though her efforts continuously fail, Reiko eventually discovers her own way to contribute to AEGIS just in time to meet new challenges from the Invaders! Then, the Far East Branch of AEGIS uncovers evidence that the invaders have begun to replace real people with their agents, but HQ refuses to devote more resources to help. With the discovery of a canine Invader, Spitzilla, will HQ be forced to regret their decision?
