Yahiko

Yahiko (弥彦?), along with Nagato and Konan, was left orphaned by one of Amegakure's many wars when they were children, forcing them to fend for themselves. The three eventually encountered Jiraiya, who looked after them and taught them basic ninjutsu. Nagato had watched Yahiko die from a Stone Chunin and killed him using his Rin'negan, in a beserk rage. Yahiko has a strong "eye for an eye" philosophy, and hates the way Amegakure is looked at by the rest of the world and hates what it has become. He is defensive of the village, saying that his dream is to stop the endless rain, which he compares to tears, and protect the nation's citizens. He has the ability to use water-based jutsu. Sometime after Jiraiya's departure from Amegakure, the three quickly gained a reputation. At an unknown point in time Pein was able to control Yahiko's body as his own. Yahiko's name in Japanese means a "vulgar" or "mean child."
