Dark Magic or Erebus is one of the two main magical elements. It is the polar opposite of Light Magic. It is black in color and often used by the Evil Crucifix to sense whether who is taking it; if it is a normal person or anyone but the Antagonist, it generates more than usual weight using dark magic, but when the Antagonist is taking it, the weight is cancelled and becomes extremely light. The crucifix also uses dark magic to sense when the Antagonist has one of the hands stretched out, opened as if he were holding something thicker than the crucifix. Once it senses it, the crucifix dashes toward the hand and forces the brain to close the hand.
