Pronimo is one of the Key Spirits .In the very beginning it was split up with Zymot having half and the Kalbu-fu the other half. Hugh was able to combine the two together to form Pronimo in the invasion of Kalbu-fu. Later when Hugh was killed, Zed's mother took Pronimo. She then lost it to Xeem, who gave it to Tusk's savior, Mirette. After being unable to control Tusker, Noa took it from her.
