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 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. Their civilization appears to be fairly advanced, best demonstrated by their usage of highly advanced forms of aviation not seen elsewhere in the Five Great Shinobi Countries. They include 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 "Fortress of the Empire"), which is described as the "ultimate weapon of destruction". Shinnō is from this village.

The main base, Ancor Vantian, was built after many research and construction by the Sky Ninja in the past, and is powered by the Zero-Tailed Masked Leech, which allowed the city to take flight. It possesses a powerful laser-like weapon at the front, which was strong enough to blast through a mountain and sweep a large section of the ocean, wiping out an armada. It was said that this laser is the ultimate weapon, and is capable of destroying the Five Great Shinobi Countries in an instant. 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. The fortress was then completely destroyed when Naruto used multiple Guts Rasengans to blow it up piece by piece, causing the debris to rain down into the ocean.

The terrorists who attacked Konohagakure possessed five 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 remnants of the fleet were completely incinerated when Shinnō launched a beam from the Ancor Vantian as a demonstration.
