Kibaoni Army Corps
The Kibaoni Army Corps is an army of Yokai based in Kibaoni Castle that seeks to conquer the world through fear. After being revived as an oni in modern times, Gengetsu Kibaoni and forces were sealed away within forty-eight Sealing Shuriken by the Ninningers' grandfather Yoshitaka Igasaki. However, after decades of waiting, Kyuemon Izayoi manages to break the seal and release the Kibaoni Army Corps and use the three spearheads to gather the "Power of Fear" from terrorizing humans to restore their leader and resume their campaign with the power of the End Shuriken.
