Nawaki

Nawaki (縄樹) was a genin level shinobi from Konohagakure's Senju clan, and is a descendant of the Uzumaki clan through his grandmother, Uzumaki Mito. He was the younger brother of Tsunade, and the first student to Orochimaru. He is also the past incarnation of Uzumaki Naruto. His dream was to become the next Hokage, like Naruto.

Background
Nawaki was born on the day of August 9th and his childhood is a complete mystery. However he also carries food for his family and eat too much. He was the younger brother of Tsunade including the grandson of Senju Hashirama, and Uzumaki Mito. He was also the grandnephew of Senju Tobirama. Nawaki had graduated from the Ninja Academy at the age of 11. He shared his dream goal of becoming the Hokage with his older sister on his twelfth birthday, who gave him their grandfather's necklace in the hopes that it would help him achieve his dream. The day after his birthday, Nawaki however died in battle after running into an explosive trap. Orochimaru was with him, along with two other genin, implying that Orochimaru was his sensei. His body was so heavily mutilated that it was beyond recognition. The necklace was retrieved by Orochimaru, and returned to a devastated Tsunade.

He was then bury in the Konoha cermontory, where Tsunade had visited his grave ever since before the Second Shinobi War ended.

Personality
In terms of personality, Nawaki was very much like Uzumaki Naruto and Kato Dan. He too held the dream of becoming the next Hokage, and was proud of the title for his grandfather's legacy. As the First's grandson he wanted to earn the title of the Hokage, and protect the village that his grandfather had founded. He was also described as someone that hated losing in battles, just like Naruto did when he became a genin. Just like Dan, Nawaki was an honorable man of justice. Nawaki also seemed to like Ramen just like Naruto. However he hated when Tsunade treated him like a little kid.

Appearance
Nawaki had short light brown hair, light brown skin, green grey eyes and distinct blushes on his cheeks. For attire, he wore a dark teal poncho top, and light green pants. He was also gifted with the First Hokage's necklace which he wore around his neck. He also wore the Konohagakure Forehead Protector on his forehead. According to Dan, Naruto bears striking resemblance to him.

Fourth Shinobi War arc
When Madara's Infinite Tsukuyomi was activated, Tsunade dreamed of a happy life with a still alive Dan as the Hokage. Including that a still alive Nawaki having a conversation with a still alive Jiraiya, and with Orochimaru.

Legacy
Decades after his death, Orochimaru would offer Tsunade the opportunity to bring Nawaki back to life, together with her lover, Kato Dan in exchange for healing his arms. The reincarnation would require a human sacrifice, though. She ultimately refused, realizing that Nawaki and Dan would not want her to sacrifice the lives of others in exchange for theirs.
