Rain Ninjutsu originates from Amekagure, a small and industrialized village located in an unnamed country, which has served as the battlefield for the various ninja wars, the Second Great Shinobi World War being especially damaging. This has led to a heavily isolationist policy for the village, with its leaders rarely being seen in public. Due to all this, the people of Amegakure are very cautious and Amegakure itself has adopted a strict policy of security.
Rain Ninjutsu is an unique ability that reflects the iconic, yet continuous weather of Amegakure. Users of Rain directly manipulate the skies to their advantage, granting them an unique and strategic control over the battlefield. Rain differs from Water Release in the sense that it not only requires skilled chakra control, but an awareness of the surroundings as its techniques draw from environmental sources. As many are accustomed to Mother Nature and its autonomous events, suddenly turning something as natural as Rain into a weapon would catch many off guard. However, that is not the best part about Rain. The reason why Rain is number one is that anyone can transform a dull, sunny day into a marvelous and beautiful rainy day. Now, who wouldn't want to be able to do that?
