In the near future, various forces will compete for interests, and disputes will arise everywhere. Noah Technology has prioritized the development of a powerful malleable tactical exoskeleton - [E.T.E], and built a huge annular orbital base equipped with super weapons - [Sky Dome] over the equator to monopolize resources. The sky was obscured by a huge amount of steel, darkness shrouded it, and despair spread. As a result, the major forces of mankind united and launched a counteroffensive against Noah Technology, which almost wiped out the ecology on the surface. Since then, various forces have jointly developed a new type of combat mecha [E.T.E], established the "Human Alliance", and entered a state of confrontation with Noah Technology. Somewhere in the world, the Ninth Entente, a combat organization directly under the Human Alliance, is waiting for a visitor...... Your arrival will be a ray of hope for the E.T.E. Maidens, illuminating the long night in the ruins of the apocalypse. [previewyoutube=acL_d9ZHyoU;full][/previewyoutube]
