Sakuma 佐久間中尉

He is a first lieutenant in the Imperial Japanese Army. Under orders from Col. Mutou, his CO, he is transferred to the newly minted and classified D Agency to report on its progress to the Army General Staff. What he finds when he inspects the members of D Agency shocks him. He is a straight-arrow officer, for whom the unrestrained and undisciplined attitudes of D Agency operatives are a source of frequent resentment.
