A healer's heart knows compassion, and the world of Naruto is no exception.
Takagi Naohito is about to challenge traditional medical beliefs!
Organ transplants, human cloning, even artificial bio-humans.
“Choose between the constraints of traditional thinking and a far higher patient survival rate, Third Hokage.”
During the Second Shinobi World War, Takagi Naohito stood before Hiruzen Sarutobi and challenged him: “Do you want the patient to die or live? That's up to you. After all, you're the Hokage.”
He introduced a rule to the shinobi world, one that was never officially proclaimed but was quietly observed by every major ninja village.
During wartime, medical ninja are not to be killed.
