not personally, however i do know someone who had an encounter with a demon by the name of lucy/luci. when she spoke to a pastor about it, the pastor explained that satan (lucifer) often tries to speak to/harm people in the form of “luci,” because she looks like a harmless child that someone may be drawn to help. i would not reccomend interacting with her. the name “luci” may actually come from a shortened version of lucifer, the name of the devil.
