Who you are is already a name on a door
You are the detective the agency can send into EDEN. Face and first name are yours; the job is not. The collected Complete Edition page names Aiba — Takumi or Ami — as the person on this walk. The same box also holds a second campaign with a different person and a different first morning. Pick the story you want to walk, not the portrait that looks sharpest on the title screen.
Heads up. People start Hacker's Memory 'for the extra Digimon' and then ask why a case they have not opened will not explain itself.
