What happens when, eight years into the future, a new "Twin Dark" rivalry is formed? Who is it? Will this one go the same direction as the rest? Or will the two find their own path? This book is basically my headcanons set to story. Bungo Stray Dogs and the characters are owned by Kafka Asagiri and Sango Harukawa, not me, as nice as that would be. Before chapter 113. Credits to the artists. I made the cover. No stealing pls.
