In the hidden half of London, known as Reverse London, high school student Noel Niihashi leads a double life. To the public, she is simply a quiet student, but in this unseen city where dragons are a tangible and often dangerous reality, she is a witch for Wing Bind. This secret organization is tasked with the crucial purpose of regulating all contact between humanity and the powerful creatures that exist alongside them.

Her duties are a complex balance of the extraordinary and the mundane, chief among them the protection of Balgo Parks, a young man who uncontrollably attracts dragons and is therefore under the agency’s constant, complicated watch. This delicate equilibrium between her two worlds now ripples with new tension as Macy Baljure, a figure from her partner’s past, unexpectedly reappears in Reverse London, bringing with her circumstances that are far from clear.
