Self-Healing Technique

Upon forming the necessary hand seals, either immediately before or after being struck by an attack, the user's body will rapidly regenerate to heal all recent injuries, leaving no lingering traces of said wounds. This technique can also negate the effects of venom on the user's body.

With the aid of a special core made from Scientific Ninja Tools, the technique can be augmented to activate instantly and even restore the person from the most maiming of damage, including getting their head obliterated, restoring them to their original form within seconds. The core can be moved around the body via hand seals, lowering the chances of its destruction.

Trivia

 * Victor, another member of Kara, was said to possess a powerful regeneration ability, although it's unknown if it's the same technique as Boro's.
