Void

Void (Japanese: 空ヴォイド, Kanji translation: Hollow, Romaji: voido) is a black magic teleportation spell.

The spell's effect seems similar to how stronger mazoku accomplish instantaneous movement: the caster disappears with all his clothing and equipment, and re-materializes somewhere else. The effect is not truly instantaneous however, as there is roughly a second of delay between the caster's dis- and reappearance. The range of Void is not surely known, but it should at least allow movement across several rooms at once. Apparently, the spell can only affect the caster; the sorcerer cannot take any of his allies with him.

The single appearance of Void so far is in the 10th novel; since it was used only by the mazoku-human chimeras among the organization of the antagonists, it is likely that the spell cannot be cast by ordinary humans because of the lack of magic capacity or other reasons.
