While Jukan is in Sage Mode, he molds chakra in his abdomen except the chakra gathers in between his hands akin to the way Naruto holds a Rasengan with two hands. When completed, the conglomeration of chakra-turned-fire forms into a tomoe shape. Jukan could then throw the completed jewel which would explode and engulf a 20-foot diameter circle. The explosion is in the fashion of a cone with the top portions slightly curved inwards.
