Humanity faces extinction when colossal entities called Vertices materialize across the globe, reducing cities to rubble and forcing civilization to the brink. In desperation, the military develops massive mechanical suits designed to counter this overwhelming threat. Young pilots from around the world are conscripted into an elite international task force, each bringing their own skills, trauma, and reasons for fighting. As these recruits struggle to master their machines and work together against impossible odds, personal conflicts simmer beneath the surface. Trust becomes as fragile as their equipment, and some question whether their commanders truly have humanity's best interests in mind. Every sortie could be their last, yet retreat means watching the world burn. The series balances intense mecha combat sequences with quieter moments exploring what drives ordinary people to stand against extinction. Camaraderie forms in the heat of battle, but so do doubts about the cost of survival. The Vertices keep coming, and the only choice these pilots have is to keep fighting or let everything fall.
