Naruto is an ongoing Japanese manga series written and illustrated by Masashi Kishimoto. The plot tells the story of Naruto Uzumaki, an adolescent ninja who constantly searches for recognition and aspires to become a Hokage, the ninja in his village that is acknowledged as the leader and the strongest of all. The series is based on a one-shot comic by Kishimoto that was published in the August 1997 issue of Akamaru Jump.

Amegakure (Amegakure no Sato; Literally meaning "Village Hidden in Rain") is a small yet highly industrialized hidden village located in an unnamed country. A number of smaller villages surround Amegakure. As its name suggests, it rains almost constantly. Many shinobi from this village seem to wear a kind of mask that allows them to breathe underwater.
