Ame orphans (Earth-2356)

The Ame orphans were a trio of Force-sensitive Human children—Nagato, Konan, and Yahiko—who lost their parents due to Ame's involvement in the Second Stark Hyperspace War. They looked after themselves until they were found by the legendary trio of then-Jedi Knights, the Sannin. One of the Sannin, Jiraiya, remained behind to provide the children food and shelter while also teaching them Force techniques to defend themselves.
