Night Wizard. A title bestowed upon those tasked with shielding the world from looming darkness. Renji Hiiragi is one such Night Wizard, frequently summoned for missions despite his sole desire being to attend school and graduate. His most recent assignment, however, is to protect Elis Shiho, a new transfer student at his academy. On her first day, Elis is pulled into the Astronomy Club by Renji's childhood friend, Kureha Akabane. She soon discovers that she too possesses the ability to become a Night Wizard, having acquired one of the seven secret Jewels: the Jewel of Kindness. Together with Renji and Kureha, Elis now embarks on her battle and her new life as a Night Wizard.
