Land of the Sky

The is featured in Naruto Shippūden 2: Bonds. The country was formed by ninja from several countries that could mold their chakra to mist in order to fly. It is said that they fought in the Second Great Shinobi World War, and their hidden village was destroyed in the war by Konohagakure for challenging the Five Great Shinobi Countries, but the country itself survived. They apparently have quite the reputation as Tsunade was terrified that the descendants of the survivors were attacking Konohagakure. They use fliers that use chakra to operate and kunai launchers that can fire rapidly along with the ability to drop bombs, and a flying contraption that can fire chakra lasers from the sky; due to this powerful and unexpected air raid, Konohagakure was easily devastated. The Sky ninja's base is a giant temple named Ancor Vantian (meaning "The Ultimate Weapon"), which is capable of flight and possesses a powerful laser-like weapon at the front. Shinnō is from this village.

The terrorists who attacked Konohagakure possessed three giant aircraft carriers in the sea for their fliers to launch and return to for replenishing chakra and weaponry. These were all destroyed when Shino Aburame's insects devoured the places, causing them to collapse and having all the ninjas on-board thrown into the sea or crushed. The main base was powered by the Zero-Tailed Masked Leech, and allowed the city to take flight. Upon Shinnō's defeat at the hands of Naruto Uzumaki and Sasuke Uchiha, the Zero-Tailed Masked Leech went berserk and devoured all the sky ninjas aboard the temple and caused it to explode and collapse.
