Quick summary: François was born in France and was interrested in studying in Art. However following the death of his father, he went to work for law enforcement, until he made it to the GIGN. After encountering 049 during a mission, he was hired by the foundation. He worked for Nu7 until a tragic accident happened. This incident split him into 2 different beings, one that continued living as if nothing happened, and another one that was stuck in a limbo. The François that still was on earth was seen as responsible for the death of multiple site staff. He was judged for it but given a second chance in site65. After years of loyalty however he could not take any longer any of the things his superiors made him do and decided to betray them, ending in his execution by the hand of A1 under orders from O5.
Now the second François is out of this limbo and now works as a Site member of Site Administration in the hopes of cleaning up the name of his predecessor, and to fix the corruption that ended the life of the first François.
