Damage: N/A
Description: Sarus is considered one of the fastest flying birds. It's not massive in size which grants its flying speed. With a wingspan of 6m, it can easily carry the user on its back. It is conspicuous and iconic and it's easily distinguished amongst the other cranes because of its red colored head that spreads to its neck, therefore the name, Redneck. The red head and neck aren't actually feathered, but rather bare flesh. Sarus is known for its loud trumpeting calls. These calls are, as in other cranes, produced by the elongated trachea that form coils within the sternal region. His calls are quite loud and can be quite unsettling to hear. His actions can be easily merged with the users own as Sarus, same as the other cranes, has the ability to easily communicate with its owner through a special mindlink or through speech. The main ability of Sarus, however, is its mastery over the wind element. Though it's considered a master it doesn't have the ability to perform all of the wind jutsus that the user knows, but rather a special ability, known only to Sarus. It can create a very thick atmosphere around a specific point, just inches thick but enough to disperse any lighting jutsu that tries to pass through it. It can form the thickening of the air in various of shapes, be it a sphere around the user or a shield-like formation in front of him (or to his sides, etc.). The thickening effects the short area around the thickening point. The process works by simply compressing the desired field of air and infusing it with its own chakra, in a way that cancels out lightning. This ability counts as 1 jutsu that the user is allowed to perform per turn.
Note: Wind ability counts as an S rank wind technique from one of the users 3 techniques per turn
Note: Must have signed the Crane Summoning contract
Note: Can only be summoned once and stays on the field only 4 turns
