Kagari

is a Genin from Amegakure

Chunin Exam arc
In the second phase of the Chunin Exams, Kagari and his teammates use a number different genjutsu to cause Naruto, Sasuke, Sakura and Kabuto to waste time and tire themselves out. After having them fight illusions for a while, Kagari and his teammates engage them. They quickly find out that what appeared to be the Konoha ninja were really just shadow clones in disguise, the real ninja having been resting. Kagari and his teammates are quickly defeated and do not pass the second phase.

Land of Tea arc
In the anime, Kagari and his teammates, under the leadership of Aoi Rokusho, are assigned by Amegakure to help the Wagarashi clan win the Todoroki shrine race held in the Land of Tea. While Oboro went to stall Idate, Kagari and Mubi prepped a ship for naval combat. After sinking Idate's ship, the Rain Genin went to battle Team 7 underwater, where they held the advantage. However, Naruto used his Rasengan training to hand them another humiliating defeat as the Rasengan created a whirlpool that sucked Oboro's team into a trench. They are assumed to have survived because of their masks.
