The 4 Nin were tasked to take down the organization known as Blue Phanton.
The 4 Nin met at a cross-over between the Land of Fire and Sound, they followed a road to a clearing and saw smoke coming from beneath a mountain. They followed the smoke and reached a ledge where they spent a considerable amount of time thinking of a plan. They finally decided to push a boulder into the encampment. This caused confusion. Zumoni then tortured a Blue Phantom Grunt and cut open his fingers. Harumi and Reiko entered the Mountain side Cave and engaged the Target, not before long Hayate and Zumoni showed up and they brawled it out. Reiko finally managed to impale the target and they all left for their respective countries.
