The Progrise Key Connector (プログライズキーコネクタ Puroguraizu Kī Konekuta) is a device that stores up to four Progrise Keys. Two are seen in the possession of MetsubouJinrai.NET, who use them to retrieve data from Zetsumerise Keys. There are also several in Hiden Intelligence's lab that are used to store and retrieve data from Zero-One's auxiliary Progrise Keys. Izu brings one of these Progrise Key Connectors with her when Zero-One goes into battle, as he can only carry two Progrise Keys on his person at a time using his Progrise Holders.
