In this DVD mini-series sequel to "Ultraman Mebius", two years have passed since Ultraman Mebius, Ultraman Hikari, and Team GUYS defeated the Emperor Alien. Monsters have continued to appear, with a newly restructured Team GUYS continuing the fight. Suddenly, a powerful alien armor created by the Emperor Alien, called Armored Darkness, arrives on Earth. It is up to the original Team GUYS to reassemble, along with Mebius and Hikari, to stop the new threat from destroying the Earth.
