Storm Release (嵐遁, Ranton, Viz: Gale Style) is an advanced naturekekkei genkai that combines lightning- and water-based chakra to create energy beams that can be guided towards the enemy.
Despite the name of this nature, it does not manipulate storms; it instead manipulates beams of electricity that flow like water. The name is more symbolic, representing the names of the natures used to create this nature. In the movie, Hiruko displays a more literal version, manipulating storm clouds charged with lightning.
