Witchcraft Works, Volume 13 in Bloomington, MN

Basis of the anime series, Witchcraft Works is a romance comedy where magic and supernational powers shape the lives of a handful of high school kids.
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?
