The Eminence in Shadow manga volume 11 features story by Daisuke Aizawa and art by Anri Sakano and Touzai.

Upon arriving at the Oriana Kingdom, Cid is broadsided by the news that Princess Rose is set to wed Duke Perv—an unexpected development that would throw a major wrench in his future shadowbroker plans! Seems like it'd be a good idea to crash the party and get the deets, but are there even bigger schemes at work behind this unholy matrimony?
