In a distant future, humanity is under siege by mysterious beings known as Phantoms. These entities defy the laws of nature and seem to come from another dimension, tearing at the very fabric of reality itself. They appear as shifting, intangible shapes that cannot be fought by any conventional means.
To counter this threat, humanity created the Valkyries — massive combat mechs, each with a soul of its own. These living machines are more than mere weapons; they have their own instincts and personalities, and they only accept pilots who can connect with them on a deep, emotional level.
In this endless war, the Valkyries and their chosen pilots stand as humanity’s last defense against the endless tide of Phantoms, fighting not just with steel, but with spirit.
