Witchcraft works. Volume 4 - Ryu Mizunagi

Witchcraft Works is set in a modern-day world where magic and supernatural powers shape the lives of these high-school kids. Takamiya Honoka is a regular student whose only problem seems to be that he sits next to Kagari Ayaka, the school's Princess'. 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 do it without secrecy.'
