Ranmaru

Purple hair of about chin length, split down the middle, surrounds a face that strikes many as faintly feminine. Whenever his dojutsu switches on, his red eyes light up. His usual outfit is a pale purple shirt striped in black along each side, worn with a waist sash, dark trousers, and sandals.

By his own reckoning, Ranmaru rates his dojutsu above even the Byakugan. Its loosely defined gifts grant extrasensory perception, so he can watch and listen to events playing out across great distances, pull the hidden thoughts from a person's mind, and foresee a string of oncoming blows. Beyond chakra, he perceives the very life force within a body, letting him judge at a glance whether someone lives or has died. His eyes cast genjutsu so overpowering that recognising the illusion brings no escape, and against rival dojutsu like the Byakugan he can raise a red dust that clouds their view of chakra. Most striking of all, he can channel a portion of his own life force into someone barely clinging to life and draw them back from death.

Born frail, Ranmaru scraped by on food from nearby farmers until his eyes accidentally marked him as abnormal, at which point the villagers cut off his meals and left him bitterly alone. Raiga, passing through on a mission and meaning to kill the boy, instead lifted him onto his back once Ranmaru sensed the grief locked inside him. Hidden beneath the swordsman's cloak, he lent his sight to Raiga's fighting and quietly observed the Mist's Seven Ninja Swordsmen. After Raiga turned rogue, the two seized a mining town, forced its people to labour, and drew in followers like Karashi, assembling the Kurosuki family. Gentle and soft-spoken, Ranmaru clung to a fierce devotion toward the man who had opened the world to him.

When Team Guy and Naruto Uzumaki arrive to bring down that family, Ranmaru is knocked clear of Raiga, whose despair lets Naruto send him over a cliff. Confessing his past, the boy begs to die, but the Konoha ninja instead carry him off to recover. He later revives a near-dead Raiga at nearly the cost of his own life, and Tenten nurses him back to health, insisting he has no right to discard a life others were denied. In the end his attempt to steer Raiga toward an atoning death unravels, and Raiga, understanding that the child can never be free while tied to him, holds his own funeral. Released at last, Ranmaru signs on as an apprentice within the Curry of Life Shop.
