20 years after Edward and Alphonse Elric died/gone over to our world, things are going their way in Amestrian, a new Führer Darrel McKalvey has risen up and Roy is now a First General, a first in line for the Führership.

Mirosuji, the Ishbalian alchemist and one of Mustang's men, steals Ed's old notebook, which has all information about homunculus and the military's old mistakes, written in it. It's the military's most treasured possession and, because Ed and Al are heroes, a national treasure.

The military is furious and they send Lieutenant General Laquisha Rundall, the black blooded alchemist, after him, one of their best soldiers. Can she get Ed's notebook back and bring Mirosuji to justice, or will Mirosuji talk her to his side? A chase all over Amestrian is the outcome, while in Central, some high ups are planning something evil. Will history be repeated and will this end in a second rebellion among the military {like Ed and Al had} or will Laquisha and Mirosuji stop it? Or does Mirosuji have to do it alone?
