Shadow Ruler

Shadow Ruler is an organization that seems to be somehow related to the Kihara Family. They have yet to appear but, according to Kihara Noukan, don't seem to operate at all in inconvenient circumstances, even if it is orders/requests from the likes of the notorious Kihara family. Their plan apparently involves manipulating the top 3 likely candidates to become board of directors for replacing Yakumi Hisako after her "death" in Agitate Halation Project.
