Witchcraft Works manga volume 13 features story and art by Ryu Mizunagi.

Alcina, a high-ranking Workshop witch, continues to investigate Takamiya, since she finds it improbable that he could take in the White Princess without her power overwhelming his. Does the appearance of so many old witches—and their clashing wishes, preferences, intrigue, ideals and beliefs—portend the outbreak of a magical war?
