Recap: After meeting Juni on Shinagawa Station, Trent agrees to help Juni with a mission to recover the Proteus Tome. Juni introduces Trent to an old friend of hers from her days at the Kusari Academy, a man named Ozu, who is later revealed to be a Lieutenant in the Blood Dragons, "a counter-political organization opposed to the Kusari Shogunate", as Juni puts it. Ozu offers to assist Trent and Juni in retrieving the Tome from their mutual enemy, Governor Tekagi, who reportedly is planning to defect to Rheinland with a transport loaded with valuables and the Tome.
