M3: Sono Kuroki Hagane
A group of kids meet in a place called the Lightless Realm, become close, then get separated and sent back to their own worlds. Years pass. When they reunite as teenagers, they discover monsters called Admonitions are pouring out of that same void, so they fight back using giant robots called Vess. It's not enough though—the Lightless Realm just keeps spreading. Things get worse when something called a Corpse shows up. Legend has it that its song kills anyone who hears it within nine days. The group ends up hearing the Corpse Song, and afterward they all start falling apart—dealing with their own personal issues instead of working together. With humanity's survival on the line, their fracturing unit might be exactly what dooms everyone.
