Set on Wall Street during the 1987 Black Monday crash, The Devil: Faust follows John Faust, a successful stockbroker who loses everything and falls into despair. At his lowest point, two mysterious figures approach him: X-Black, who embodies temptation and darkness, and X-White, who believes that no human soul is beyond redemption.

Desperate to regain his former life, Faust makes a bargain with X-Black, exchanging his soul for wealth, power, and success. Under X-Black’s influence, he rises again and surrenders himself to ambition, greed, and excess.

Faust’s path begins to change when he meets Gretchen and experiences the possibility of genuine love. Yet he remains trapped between his desire for her and his hunger for worldly success. His eventual betrayal of Gretchen leads to loss, guilt, and self-destruction.

Throughout Faust’s decline, X-Black and X-White struggle for control of his soul. X-Black exploits his fear and desire, while X-White continues to remind him that another choice remains possible. Gretchen’s love becomes central to Faust’s final confrontation with the consequences of his actions.

At the edge of damnation, Faust acknowledges what his ambition has destroyed and asks for forgiveness. Gretchen’s selfless love and X-White’s intervention open a path toward salvation. Faust ultimately turns toward the light, forcing X-Black to retreat.
