Witch Hat Atelier manga volume 12 features story and art by Kamome Shirahama.

Coco and Agott spun a well-received spectacle at the Silver Eve procession, but the wonder is quickly dispelled when an enormous terror descends upon the streets of Ezrest. The crowd is thrown into a frenzy, and the Knights Moralis, the King, and the Wise Ones rush forth to keep destruction at bay. Coco turns to Qifrey about Custas and Dagda, but no one's safety can be guaranteed once the intentions of all are laid bare under the starry sky.
