Shinjuku, in Japan. It uses technology. I didn’t even know that magic existed until a week before I came here. I nearly died, and then the city’s will picked me to defend her.

There’s yokai - monsters from folklore. But they only exist as long as people believe that they do, and most people don’t anymore. So they’re getting sick and dying. A Karas - a city’s guardian - has to keep the people and yokai in their city safe.
