He is an IJA spymaster, and the founder of the spy training school D Agency. He is often called by the moniker "Demon King," and he possesses boundless intelligence. He was once an excellent operative himself. Rumors say that his signature white glove and walking stick are borne from a botched operation in a foreign country, where his fellow operative betrayed him, and he was captured and tortured, but the details are unclear. Many have attempted to see if he is truly an ally, but all have met with failure.
