The Eminence in Shadow: Shadow Side Story.

This was an entertaining manga of Eminence in Shadow side stories (non-canon) that are pure comedy and fluff. If you're a fan, I would recommend you give this manga a try, but those who aren't Shadow fans already may find it boring or confusing to understand some of the comedy. I, for one, truly enjoyed the chibi art and fun little stories that incorporate the over-the-top comedy that makes this series so amazing. There is no central "plot" to this manga, and each chapter involves light-hearted interactions between beloved Eminence in Shadow characters. Definitely read this manga if you need something other than rewatching theanime and rereading the manga + light novels. Hope you enjoy!
