Director of DEIMOS.
Grade Noriaki is the Director of DEIMOS, and has held that position since 2004. Although he is younger than the rest of the personnel in his agency, he is a genius, and his stoic (almost humorless) demeanor has helped the agency survive through the years leading up to The Interim.
As Director, he is infamous for information control.
Grade keeps close contact with Rika Shiroi-Miyamuri, whom he reluctantly considers a mother-figure.
