R (Reverse, Inversion), Rick Basquebill.
He has a very distinct difference from other letter holders; he does not hold a specific position in the Black Tower, unlike directors like Madame Bei, Charles, or Zod, or bosses like Francis.
His true identity is completely a mystery, unknown to anyone but the Supreme Will.
Privately, he is referred to as the "Reverse Man".
He is responsible for managing an extremely secret department of the Black Tower with no fixed office location.
This department specializes in handling 'reverse matters',
which are matters that do not comply with public opinion or Black Tower regulations but are necessary for the overall progress of the world and the stability of the Black Tower world.
For instance, currently, the suppression and supervision of the Source World of Hell.
When someone seeks to uncover the truth of why the world has halted progression, they are quietly dealt with by assassins hidden in the reverse.
