This is a shikishi board of Kanade Yoisaki from the movie "Project Sekai: The Broken World and the Unsinging Miku," which was a bonus item. The serial code is not included. It was displayed in a frame for shikishi boards on a shelf away from direct sunlight. I hope it goes to someone who loves Kanade-chan. Please refrain from purchasing if you are concerned about the condition, as it has been stored by a private individual. Thank you for looking.
