火影忍者 wear the necklaces that Tsunade gave it to him.First,she gave it to Nawaka,her little brother,then he died.After that,she gave it to Dan,her lover and then he died too.They 说 that the necklaces don't except anyone but her.And when Jiraiya and 火影忍者 went to find Tsunade to make her the 下一个 Hokage,she and 火影忍者 bet that if he can learn how to use Rasengan in 1 week,she will gave him the necklaces,and he ươn the bet.Actually that necklaces belongs to Hashirama!
