Natsu

is a shinobi from Iwagakure.

Appearance
Natsu has dark spiky hair, he sports the standard Iwagakure flak jacket along with the maroon-coloured headband which has the insignia of the Allied Shinobi Forces.

Personality
Natsu is seemingly a proud person, being very concerned with proving his abilities and not being humiliated by faring poorly in the war. In extension to this he also have a tendency to argue over whom deserves the credit for killing an opponent.

Shinobi World War Arc
Natsu was heading to aid Naruto, Killer B, Kakashi and Might Guy with Neji and Shun, when he and Shun defeated two opponents with the help from Neji. They then got into an argument with each other, but Neji soon broke it up and reminded them both that the next battle is going to be on the front lines.
