The Chaos Harbingers

The Chaos Harbingers are a group of terrorists led by Shinji Yaga in the New Era that work to bring chaos into the world by any means necessary.

Background
The organization was started after Shinji became disillusioned with the newfound peace in the world after the war. Using his reputation in Iwagakure, he recruited followers and left the village after exploding a few buildings. While on the run, he comes across Tamiko, a young kunoichi from Kirigakure, who felt inspired by his cause. Over the years, Shinji has continued to gather followers that have wrecked havoc across the hidden villages
