Shin is the third son in a family of four sons. Coming from a family with a modest income, Shin was raised comfortably but never pampered in excess. From his childhood, his village sang praises of heroes who distinguished themselves in the Fourth Shinobi War; teenagers like Naruto Uzumaki, Sasuke Uchiha and Sakura Haruno, the heroic vigilante Densetsu Uchiha, the Five Kage, and even Jōnin like Kakashi Hatake and Might Guy. While he never excelled particularly in any given combat field, Shin was determined to forge his own reputation as a hero in the future. This led to a slow, but nevertheless consistent growth of character and skill, mainly done silently.
