Naruto 160

Introduces Nawaki and Dan. Shizune attempts to discourage Naruto, saying the necklace is cursed. Tsunade strolls down memory lane, remembering the death of her younger brother, Nawaki, after she gave it to him on his 12th birthday. Her proposal for each team to carry a medic was agreed upon by a man called Dan, who would later become her boyfriend and receive the necklace. Shortly after, Dan was injured and died even while Tsunade tried to heal him with hands saturated in his blood. Shizune explains Tsunade’s past to Naruto at the same time, but Naruto simply leaves to train.
