STORY INFO:
The remnants of Zangyack and Enter set their aims on the "Gen no Ranger Keys (Phantom Ranger Keys.) When all 5 are gathered, they grant the mightiest power in the universe. The Final Key rests on Earth.
Zangyack, Enter, and the Gokaiger, who are for some reason acting alongside Zangyack, discover the Key near an Enetron Tank. However, the Go-Busters are called into action to protect the Enetron there, and a fight ensues. Then, the resonating of the 5 keys and the Enetron causes an explosion!
The Phantom Ranger Keys run wild and distort space and time! Yoko, Gorisaki, J, Joe, Luka, Hakase, Aihm and Gai are pulled into the time-space distortion!
Yoko, J, and Gai are dropped in 1772, Edo Period, Japan. J and Gai have an idea to return to the present. Gorisaki seems to have been flown to the Cretaceous Period (hmmm...interesting no?), and somehow, Jerashitto ends up joing our heroes in the Edo period!
Hakase and Aihm are dropped in France, circa 1600. They adapt the guise of Nobleman and Princess (guess that ain't exactly a guise for Aihm though) and come face to face with a Phantom Thief! The Thief seems to be none other than Jin Masato....
Joe, Luka and Ryuji are dropped in the Mediterranean, circa 1400, otherwise known as the Age of Exploration.
The Phantom Keys are also deposited throughout time alongside our heroes, and battles ensue between them and the Zangyack over the keys!
In the present, the people left out of the time-jumping use the time-travelling GozyuDrill's program to upgrade the BusterMachines via the Buddyroids' Vaccine Programs. This gives the Buster Machines the ability to time travel and rescue the friends who have been deposited throughout time! As their friends and allies are saved, the true reason behind the Gokaiger's alliance with Zangyack is revealed!
However, for this Rescue Plan to work, a big sacrifice is required of the Go-Busters. The Go-Busters give into grief, as the Gokaiger look on...
Meanwhile, Zangyack and Enter aren't just waiting around to attack the Earth. The greatest battle these two Sentai teams have ever faced begins now!
Also, what power does holding all 5 Phantom Keys grant to their user?!
