Hishōten

If Lady Tsunade's technique is referred to as the "absolute pinnacle of medical ninjutsu, created by the greatest of medical ninja", Magai's custom self-regenerating jutsu lies on a different plane of existence. It works in a similar manner to Creation Rebirth, using chakra to stimulate proteins and hasten the creation of new cells from previous tissue; However, it lacks Lady Tsunade's greatest weaknesses. What grants Magai his great medical prowess is his naturally immense vitality and life-force. Like a close relative, Magai possesses a unique healing chakra which is birthed from his powerful life-force. At base, it grants him incredible regenerative capabilities, gifting him a healing factor twice as powerful as a normal human. But by using his mastery over medical ninjutsu, Magai can course this healing chakra and increase its density and potency around a specific area. Causing his wounds to heal instantly.

Magai's technique surpasses Tsunade's in ways that it has no limit to what it can regenerate. By hastening cell division and using it to birth new tissue, Magai's entire body is capable of being regenerated. Giving him a form of immortality. He can recreate limbs, organs in a matter of seconds, and on various occasions his own eyes. Techniques and conditions that cause necrosis, consume flesh or induce rotting become useless as he will simply regenerate. Magai tries to keep from activating this technique as his healing factor is strong enough to heal most wounds at a rapid successions. It is one of three medical ninjutsu that lacks any use of seals. However, some call it the strongest due to its removal of preparation and body limitations.
