Nagato Yorozuya

was a Jōnin from Yamagakure and the husband of Chiyo Yorozuya.

Background
Like his future wife, he grew up in the capital of the Land of Mountains, Edo. According to both Chiyo and their other teammate, Nagato was a natural prodigy and showed great potential even as a young man. Along with his teammates, he was eventually promoted to chūnin. However, among his team, he was the only to become a jōnin prior to the coming conflicts. When Ryun Uchiha began uniting the shinobi of the country for his Yamagakure, he and his team joined him on the frontlines, fighting in the Land of Mountains Civil War against the likes of the Mochizuki Clan. During peacetime, Nagato developed a strong rivalry with his other teammate, and the two frequently fought to prove which was the more powerful shinobi. One such fight broke out in the middle of the village, and it was rumored that the Yamakage himself had to intervene to prevent them from damaging the village's infrastructure. Nagato's skills became so well known in the village during this time, that he was asked to lead Ryun's personal security detail. Their rivalry grew more intense once both men realize that they were both in love with the same woman; Chiyo, whom they had grown up in Edo with, and whom had come to accept them both as her closest friends. However, much to his rival's dismay, Chiyo slowly began to fall for Nagato, and before long, the two stopped their constant fighting so as not to drag her into their bitter conflicts. Nagato went on to marry Chiyo, his childhood friend and teammate, who bore him a son not long after. Unfortunately, their marriage, while seemingly full of love, was cut short. Only a few years after the ceremony, the Samurai–Shinobi Civil War broke out between the remaining samurai, aiming to keep their way of life, and the rising bud of the shinobi, who were beginning to take root all over the Land of Mountains, thanks to Yamagakure's influence. Nagato, Chiyo, and their teammate were sent to the frontlines, only for them to become separated during the fighting. His rival arrived in time to back him up, however, he failed to miss a stray explosive tag, attached to a kunai, and Nagato threw himself in the way to protect him. The resulting explosion fatally wounded Nagato, and, as he died, he asked his rival to protect Chiyo and his son for him, as well as to always remain loyal to the village. His sword and jutte were returned to Chiyo after the war's end and his body was buried near Higurashi Shrine, while his name was inscribed on the shrine itself, along with the other dead-at-war. After news of his sacrifice reached the Yamakage, Ryun declared him the.
