Witch Craft Works

Japanese Title: ウィッチクラフトワークス

Plot
Takamiya Honoka is a regular student whose only problem seems to be that he sits next to Kagari Ayaka that everyone at school calls her the Princess. They have never spoken to each other before and any small interaction between them immediately results in her fanclub beating him. Yet when a falling part of the school's building is about to send him to the afterlife, it's Kagari that comes to his rescue. Only she's dressed as a witch, carrying him in her arms and floating on a broom. Kagari tells him it is her mission to protect him and that now she can finally protect him openly rather than undercover. From then on, his ordinary school life is completely turned upside down, as he discovers that most of his classmates are not what they seem.
