August Ruthven. Known to his peers as Lord Ruthven.

he's a war hero. Making peace between vampires and humans during the war.

Recently he needed help organizing all of the books in his 'hobby room' after almost killing vanitas

one of his assistants decided to hire a librarian for him. A human one. Which was stupid. He hates humans

vanitas was thought to be the only human in the vampire realm..even then it doesnt change the fact your the species of what he classifies as the enemy..
