Gin-iro no Olynssis - S01

In the year 3567, humanity’s once-great civilization has collapsed, leaving people to survive in the ruins of the past. Their lives are constantly under threat from the Gardeners-mysterious unmanned weapons of varying strength, dispatched from the Moon. To survive, brave young hunters take on the dangerous task of fighting these machines. Though much of the world lies in decay, fragments of advanced, self-sustaining technology still function in the remnants of cities, offering meager support to those who remain. One day, Tokito Aizawa encounters a girl named Tea, awakening a power far older and greater than that of the Gardeners. Unknowingly, he sets in motion events that could lead humanity toward a new hope.
