While technically being centuries old from her military droid origins, she has been recoded and refurbished for human life as a 15 year old girl, currently being home schooled by her 'parents' Sapphire and Crystal Vironica. Her original chassis was manufactured on Febuary 16th 1756 but she was "born" on july 23rd 2009 and was refurbished on june 6th 2021. She has very little presence before her presence in DX Playlist, being in a few arts and doodles made by Summer.
