In flashbacks, Eiji fails to save a girl amidst a foreign civil war. In the present, Satonaka meets with Eiji to collect Kougami's fee until an explosion occurs outside.

As Maki observes the bomber, Kougami Biotech Laboratory technician Toru Tadano, Ankh scolds Eiji, who later discovers Maki's whereabouts.
