When the brutal warlord Gengetsu Kibaoni was killed by the ninjas of the Igasaki Clan, he declared he would return to unite the world through fear and terror. Kibaoni and his generals eventually resurrected as demons and led an army of Youkai to wreak havoc throughout Japan, but their reign of terror was stopped by Yoshitaka Igasaki who sealed Gengetsu away with the 48 Sealing Shuriken.
444 years later, in 2015, the seal wore off and Gengetsu was freed by the Kyuemon Izayoi and his remaining followers. Because Gengetsu was unable to assume a physical form, Kyuemon set about gathering the Power of Fear to fully revive Gengetsu by sending out Youkai to terrorize humans. Kyuemon also revived the three generals of the army, Raizo Gabi, Msakage Tsugomori and Ariake no kata, to assist in this quest.
Gengetsu Kibaoni was eventually revived following Mangetsu Kibaoni's death after Kyuemon used Ariake no kata's sorrow to revive Gengetsu. In the final battle, Gengetsu absorbed Kyuemon to power himself up but was destroyed by the Ninningers after Kyuemon broke free with their encouragement.
After Gengetsu's death, the Kibaoni Army Corps was taken over by a revived Ariake no kata and Juza Yumihari.
