Lumi is the former artificial intelligence of the DFS Lavie. She was given a human form and her AI self was transferred to a human brain by ITC’s Medical Research Division. Due to the fact that she was once the ship’s AI she has all the knowledge the ship’s database had. As a result of this she has many equivalent degrees and could even be considered a medical doctor. Her physical appearance is that of a 26 year old. Her full bio is on the Lavie forums.
