Chief of Vector First R&D Division, and head of the KOS-MOS project. Shion took over the development of the KOS-MOS project after Kevin Winnicot, her former boss and fiance, after his death. Shion was always a very kind child and she cannot stand to see the ones she cares about being harmed. Because of this she sometimes forget that KOS-MOS is developed as a weapon and she struggles with the morality and acceptance of that fact.
