Void Healing (空医, Kūi) was a Void Magic Spell.
A simple yet an extremely potent and effectively spell, it essentially allowed the caster to appear nigh invincible to those with an untrained eye. Whenever Dante sustained any form of injury, he enveloped himself in a blood-red aura of Void Energy. This aura of Void Energy was then used to heal Dante to an uninjured state, deleting garnered wounds and healing it back to perfection with negative energy. Upon using Void Healing, Dante was known to laugh hysterically, implying that each subsequent use caused the wielder to inch closer to insanity. As a result, Dante had been noted to sparingly use Void Healing unless the worst circumstances called for its use.
