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. The protagonists of the story are witch duo Noel Niihashi and Ninny Spangcole. They are protection agents for Wing Bind. Their mission is to protect and manage the dragons within London on behalf of the people.

The show revolves around Ichigo Kurosaki, a good-hearted 15-year-old high school student who carries the undesired ability to see spirits. Others in his family (two sisters and his father) carry this ability to some extent as well. One evening, he encounters Rukia Kuchiki; a Shinigami, or Death God. It is her job to usher lost spirits to Soul Society, and to also eliminate those which cross over from the Hollow World.
