M3: Sono Kuroki Hagane Recap

A spreading darkness has swallowed part of Tokyo and given rise to monstrous beings called Admonitions. Akashi Saginuma and seven other young people are brought together to pilot machines against them, but their missions lead into a danger tied to their own pasts.

Akashi’s encounters with the darkness expose disturbing truths about the machines meant to protect them. Memories of his brother, the suffering of his companions and his wish to protect Sasame complicate a battle whose human cost becomes increasingly difficult to ignore.
