Shiren set

The Shiren set is a vanity set exclusive to the  and Wii U versions of the game that looks like the character of the same name from the game series Shiren the Wanderer. It consists of Shiren Hat, Shiren Shirt, and Shiren Pants. The Shiren Hat has a 1/250 (0.4%) chance to be dropped by Fire Imps and the Shiren Shirt and Shiren Pants are purchased from the Clothier during a full moon.

Trivia

 * This set was added as a replacement for the Plumber's set due to copyright concerns over the latter costume. As such, the method of obtaining both sets is completely identical.
