The manga tells the story of Mira, who leads an evil organization trying to take over and destroy everything. Earth is under attack, but a magical girl named Byakuya Mimori stands up to Mira's group. As they face off, something unexpected happens—Mira falls in love with Mimori.

A large scale catastrophe is occurring across the planet. Ability users are discovered after the appearance of a mysterious fog, apparently having committed suicide, so the Armed Detective Agency sets out to investigate these mysterious deaths. The case seems to involve an unknown ability user referred to as "Collector," a man who could be the mastermind behind the incident.

Trust and courage are put to the test in order to save the city of Yokohama and ability users across the world from the grip of Collector where the Armed Detective Agency forms an unlikely partnership with the dangerous Port Mafia. 

Historically, 72% of all the deaths in London are related to dragons, fantastical beings invisible to the majority of the people. While unknown to most, some people have been standing up to these dragons. Only inhabitants of Reverse London who live in the hidden "reverse" side of London can see the dragons. Even then, only a selected few become qualified enough as witches or wizards to make direct contact with them. The protagonists of the story are witch duo Noel Niihashi and Ninny Spangcole. They are protection agents for Wing Bind (WB), an organization for dragon conservation and management. Their mission is to protect and manage the dragons within London on behalf of the people.
