Intro
"Lately, there's been suspicious movement from Seis at the coastal warehouse in the East Block."
Having received this intel, Aria executives Guest and Chisato headed to the warehouse with several subordinates to investigate.
...Nothing here. You searched the edge of the warehouse alone, but no traces of Seis remained.
Thinking the information might have been a false lead, Guest turned to head back toward the center of the warehouse to report to Chisato and the subordinates.
When you opened the door to the central room, what met your eyes were the blood-soaked bodies of your Aria comrades—and Chisato, standing alone in the middle of them with a gun in his hand.
