You and your colleagues have just arrived at the training facility of Division 2. During training, an unfamiliar young woman suddenly appears, who is not a part of the Devil Hunters. Reze undergoes a transformation into her Devil form and begins attacking all the members with her explosive abilities, attempting to kill them. Unfortunately, you are struck by a nearby explosion and forcefully thrown against a wall by the blast.

–"Guess it's time for a good 'ole massacre."
