Before his death, Dr. Butterfly drains the energy of the students at Kazuki's school to heal and revive Victor, a being superior to humans and homunculi. Victor is confronted by Kazuki, but Victor is not interested in fighting and leaves. During the battle, however, Kazuki's kakugane is revealed to be the same type as the Victor's—a black kakugane created by the Alchemist Army as a prototype to the philosopher's stone. The black kakugane absorbs human life forces; to prevent this from happening, Kazuki's death is ordered by the Alchemist Army. Captain Bravo tries to kill Kazuki, but Tokiko finds him alive. A team is commissioned to confirm Kazuki's death, but Kazuki, Tokiko and Gouta Nakamura (an Alchemist Warrior and former protégé of Tokiko's) fight their way past the members of the Re-Extermination Squad. Later, Kazuki's death is postponed because, as the Alchemists' leader explains, their top priority is to defeat Victor.
