Takamiya Honoka is a regular student whose only problem seems to be that he sits next to Kagari Ayaka, the school's 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?'
