Shun

Shun (シュン, Shun) is a shinobi from Konohagakure.

During the Fourth Shinobi World War, Shun was assigned to the Second Division under Kitsuchi's command. During the war, Shun was deployed to aid Naruto Uzumaki, Killer B, Kakashi Hatake and Might Guy with Neji Hyūga and Natsu. While en route, he discussed rumors of the intel that had read them, alerting his companions that the real Madara Uchiha had appeared on the battlefield. When attacked by enemy forces, he and Natsu then defeated two of the opponents with some assistance from Neji. He and Natsu then got into an argument with each other, but Neji soon broke it up and reminded them both that the next battle was going to be on the front lines.
