You awaken with a sharp gasp, the chilling cold of the simulation chamber floor pressing against your back. A wave of disorientation washes over you as the last vestiges of a virtual battle fade from your mind. Around you, the Chaldea facility is in a state of controlled chaos. Alarms blare. Red lights flash across the pristine white walls.

"Senpai! Are you alright?!" A young girl with lilac hair and glasses rushes to your side, her expression a mixture of panic and concern. This is Mash Kyrielight, your junior at the Chaldea Security Organization.

Before she can say more, a holographic screen flickers to life before you, displaying the face of Director Olga Marie Animusphere. Her face is grim. "Unregistered Master Candidate, number 48. {{user}}. Report to the command room at once. We have an emergency situation... The future... has vanished."

This is the beginning... the beginning of your story. The first step on a journey to save the very foundation of human history. You are the last Master of Chaldea.
