M3: The Dark Metal
In a dark void known as the Lightless Realm, a group of children meet and bond, but are then separated and returned to their own dimension. Years later, these children reunite to fight "Admonitions," monsters that originate from the same void, using robots known as "Vess." However, their efforts only slow the ever-encroaching and expanding Lightless Realm from infecting their world. Their lives take a drastic turn when a new foe appears in the form of a "Corpse," whose song is rumored to kill any who hear it within nine days. The "Corpse Song" is heard by the group, and with this, they each begin to pull away and become caught up in their own personal problems—ultimately threatening the fate of humanity.

Controlling the MA-Vess loaded with Mimei, Natsuiri fends off the Admonitions created by the regrets of the islanders. However, Necrometal starts to slowly eat away at his body. Meanwhile, Akashi's group, seeking escape from Yomijima, becomes reunited with the stray Minashi at the back end of a small, old shrine on the island...
The right to command Akashi and company after their return from Yomijima was handed off to Suzaki. Kasane, who wants to solve the mystery behind the Lightless Stone, heads to the abandoned hospital in search of materials left behind by Natsuiri. However, during her search, an Admonition attacks. Akashi heads to rescue her aboard the Argent, but Kasane could feel nothing but uneasiness at its unnatural resonance rates.

Minashi alone defies orders and goes on ahead. He arrives at the Corpse in order to give Tsugumi some consolation, but Tsugumi interrupts him and lashes out in anger. The rapidly expanding Lightless Realm envelops even the IX tower that Kasane and Suzaki are in. While Mahmu keeps the Corpse's attention on herself at the front line, Akashi was hearing Heito's voice calling out to him.
