Shouichi is part of the Millefiore Family and is captain of the White Spell 2nd Rose Squad, and one of the six A rank members in the Millefiore. It seems that Byakuran and Shouichi have a somewhat close relationship; Byakuran calls Shouichi "Shou-chan" and seems to trust him the most. He is currently involved in some very important research for the family.
