Mystical Force: Vol. 4 Many are 1, 1 is 0

Shi-ria tries to stop Dead-Eye from stealing a magic scroll, only to learn it was Zolida who hired her. Why does Zolida want this scroll? Unfortunately, neither Shi-ria nor Scarlet Knightwalker have time to figure that out. When Shi-ria is badly injured fighting Zolida, Scarlet Knightwalker is forced to turn to someone she doesn't fully trust, Mystic, in order to save Shi-ria's life.

Meanwhile, Aanjay and Jimomaru are once again determined to destroy Sister Rose as revenge for the Order of the Cross persecuting them. Aanjay and Jimomaru soon find themselves getting some unexpected help from Zolida, who uses the stolen scroll to bring some help of her own. Help in the form of a new being named 0, a being from another dimension. A member of a species called the 1, 0 is an omnipotent entity with the powers of a god and the personality of a bratty child, tormenting insects because he's bored.

Zolida tries to get 0's help in punishing humanity. However, things quickly spiral out of control. First 0 uses his powers to turn Tokijin into a human and then turn Rose into a demon. Before long he's turning all humans into demons, knocking planets out of orbit and causing all manner of chaos for his own entertainment. It seems no one, not even Zolida, is able to stop him. Is there anyone powerful enough to control this mad god? Or is the world doomed to an eternity of insanity at the hands of this omnipotent prankster who sees reality as a game and all living beings as little playthings for his own amusement?
