This technique is The foundation of most if not all of the An'un clan's Hidden Cloud style. The user moulds chakra using special, one handed signs invented by the founder before expelling a mass of clouds from their body. These clouds are typically white, but may be any particular colour. These clouds may then be manipulated directly, or used in other Cloud Style techniques by adding additional signs. Of particular note is that while this style is based primarily on the water nature, lightning or wind natures can be added to techniques in order to bring about additional effects. The philosophy of formlessness behind the style is exemplified in this technique, in that it may flow or transform into any other technique with little to not warning.
