Kuni Ageku was a Crab Clan tsukai-sagasu. Incredibly talented and devoted, Ageku destroyed many Tainted artifacts and killed many Bloodspeakers. His business kept him away from home for so long that he failed to notice his wife's use of Maho until he came home one day to find her poised over the murdered bodies of their family. Ageku destroyed her, but was shamed for failing to see such a dangerous thing within his own household.
