Evolver (2004)

Original title: イヴォルバー -EVOLVER-

An anti-alien task force with battle suits based on advanced technology, Evolver, returns to finish the war they thought they ended against the Efreet. Only a small percentage of the population has the genetic factor that allows them to use Evolver technology, leading to a ragteam team with wildly diverging backgrounds: a stubborn schoolgirl, a disabled soldier, a practical desk clerk, and an amnesiac murderer. Evolver not only has to deal with the returning threat of the Ifreet, but with their own personal issues. A mysterious girl dressed in white that wants to unlock their inner power that could change the tide of battle...but at what cost?
