The player wakes up from a consciousness repair module, broken by an intruder. She takes a sample of the player's blood, morphing into their form. The player is later saved by Adjutant Nightingale, who reveals herself as the player's secretary, and the player is the Chief of the MBCC, where they "shackle" dangerous Sinners and keeps them from damaging DisCity. The intruder's invasion sets all the Sinners free, except two - Hella, and Hecate. They both are shackled by the Chief after Hecate teaches them to control their powers. They then take out waves of prisoners and mutant beasts until they reach the intruder. The application of the shackles reveals the intruder's true form, and she promises to wait at the end of their journey with all the answers they seek, and leaves.
