The butler to the King's Righteous Man must be someone who is brave, skilled, loyal, and above all, ready for any eventuality—whether it be an assassin after his master or high tea for ten guests on short notice.

Vincent Sinclair is the replacement for Sir Percival's former butler who died under...unfortunate circumstances. It is now his duty to serve the Righteous Man in whatever he needs, whenever he needs it.

One of his duties is training the master's son, Lysander, who will take over the title of Righteous Man when Sir Percival ultimately retires—or is taken off the field by less savory means, whatever comes first. Sinclair finds Lysander to be a bright boy, but one weighed down by the shadow of his father's demands. Sinclair takes it upon himself to help the young master shine, so that Lysander can prove to his father that he has what it takes to be the next Righteous Man.

This prequel story to The New Emperor's Concerto shares a look at what it's like being in the family of the King's Righteous Man from the butler's perspective
