Trivia

 * Despite the name of this nature, it does not manipulate storms; it instead manipulates beams of electricity which 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.
