The Shusui, along with a collection of other Meito's are considered national treasures of Wano. The country follows a policy of isolationism, meaning that contact with outsiders such as pirates and other countries is prohibited. Leaving the country's borders is also considered a crime. Non-National Meito carries beware carrying your weapons in the open. This area is governed by Four Major Clans.
