The Beiri Clan is a new clan that arose 15 years before the start of the series. It's main house is located in Kusagakure.
The clan was founded one year after the birth of kai beiri and Noboru Beiri's first daughter Gurei. kai spent a majority of Gurei's childhood out on missions, so she took over as the mother figure for her three younger siblings.
After graduating the Kusagakure Ninja Academy, Gurei was forced to spend time away from her family. The current status of the main house is no clear, but it is seemingly good since Gurei occasionally mentions them. the Beiri clan grow to be powerfull
The Beiri Clan's Kekkei Genkai is called Scale Armor Jutsu, in which the user grows an indestructible armor of scales over their skin. The jutsu only lasts one hour, then the scales peel off. Because the scales grow directly from the top layer of skin, the scales peeling off removes the top layer of the user's skin, leaving them more vulnerable to injury.
