The Sankishin(三輝神, Three Radiant Gods), also known as the Original Units(オリジナルユニットOrijinaru Yunitto), they are the base for Nox Nyctores. Unlike the Nox Nyctores, the Original Units draw power directly from the Boundary. This is mentioned in the Tsukuyomi Unit's chant, as well as being shown by the Susano'o Unit being unaffected by Celica's power, while the Amaterasu Unit was physically present within the Boundary itself.
