Суґінамі Судзаку

The leader of the Alchemists faction as well as the organization's CEO. She is the unifying "conscious" of the Suginami Design Children. She had allied herself with the Inquisition and was responsible for keeping Kiseki Kusanagi asleep in a dreaming state before the attack on the First Laboratory.

Suzaku, much like her design children, is solely fixated on the progress of science and development. She takes child-like joy in discovering something new and shows juvenile mannerisms in her forwardness and gestures. However, as the leader of the Alchemists, Suzaku still exhibits cautious thinking and decision making to make her alliance with Sougetsu a lot less one-sided.
