Captain Yukio Senzuri was an officer in the Akai Tora during the Great War. It was he who told Geraud Aurelac that the Akai Tora were not Yamatians at all, but the blood from which the Yamatian people sprang. According to Senzuri, his people had once lived in Grandbell, before the Explosion, and sought to redeem the dishonour of their people. These proto-Yamatians worshipped the Dragon God Rauhdrskal, and disapproved of the move in Yamato itself to the worship of a gaijin god, Mardük. Ironically Senzuri did not know that Rauhdrskal and Mardük were actually different names for the same god. Senzuri fell in the First Battle of Remonton.
