Naruto: My Body Heals Instantly

Reborn as an orphan in a brutal Konoha, Kimura Takuno faced a death sentence: Danzo's Root.

An unparalleled regeneration that healed any wound in hours, not weeks. Medical ninjutsu became his perfect cover, allowing him to cultivate strength far beyond a normal Jonin, all while remaining utterly overlooked. Now, with graduation and the Chunin Exams looming, the 'weakest' ninja must navigate a world of genii and danger. Will his immortal body be enough to master the legendary Eight Gates and defy the ruthless forces trying to control him?
