The Progrisekey Connector (プログライズキーコネクタ Puroguraizukī Konekuta) is a device that stores up to four Progrisekeys. There are three in Hiden Intelligence's lab that are used to store and retrieve data from Zero-One's auxiliary Progrisekeys. Izu brings one of these Progrisekey Connectors with her when Zero-One goes into battle, as he can only carry two Progrisekeys on his person at a time using his Progrise Holders. A black variant named the Zetsumerisekey Connector (ゼツメライズキーコネクタ Zetsumeraizukī Konekuta) is used by MetsubouJinrai.NET to retrieve data from Zetsumerisekeys.
