The Mamiya Household (間宮家 Mamiya Ie?) is an onmitsu clan of spies who work with the government, doing public covert affairs while maneuvering through life-risking difficulties. It is the primary household of Akari Mamiya, the AA protagonist. Also, the family is highly charismatic for having only females.

Living through generations, the household was split into 2 clans. One is the Dawn House (暁座 Akatsuki Za?) who are bound to contingency duties and VIP protection, the other is the Dusk House (宵座 Yoi Za?) which lives through assassinations, being info-brokers and other dirty work.

Their residence was in Ibaraki Prefecture, until it was raided and scattered by IU's special forces.
