Ordinary weapons prove ineffective against the Cherubim, and rings of projectors around the remaining cities, tapping into Earth's strata to project a quantum shield to keep Shadow Angels from entering or materializing in them, provide only limited protection. However a human expedition under the leadership of Gen Fudo excavates three very technologically advanced fighter planes, and an organization called takes over the research of these planes, called , trying to identify how to use them. The three Vectors, colored mostly in white, are identified as the green , the blue , and the red . DEAVA discovers only people with special powers, called , can use the Vectors and the three Vectors are in fact the pieces of Aquarion, the same robot used to fight the Shadow Angels twelve millennia before. They also discover the Elements can ultimately unite the Vectors into one of three formations of the giant robot in battle, and can use it to fight and defeat the Cherubim.
