Shimei Yuuki

A child prodigy, he holds mathematics and theoretical physics degrees at the age of 15. He is also the systems administrator of the AESOP computer, and is the only commissioned officer who remained on board the Amaterasu. Shimei spends most of his time away from the rest of the crew because of the need to work in a sealed room with AESOP. He always seems to smile even when in the face of imminent doom. Shimei dies in the final episode piloting the Amaterasu as a fireship, asserting his official rank as superior to the cadets'.
