Cop Craft: Dragnet Mirage Reloaded (Japanese: コップクラフト DRAGNET MIRAGE RELOADED, Hepburn: Koppukurafuto Doragunetto Mirāju Rirōdeddo) is a Japanese light novel series, written by Shoji Gatoh and illustrated by Range Murata.
Fifteen years ago, a mysterious hyperspace gate appeared over the Pacific Ocean in our world.
Elves, fairies, and other fantastic creatures came through the gate from the other side and established diplomatic relations with Earth.
In the present day, Kariana Island and its main city of San-Teresa serves as Earth's "front door" to the magical world on the other side of the gate, and over two million non-humans live within the city, mixing with additional human residents.
This results in both prosperous growth for the island, and a seedy underbelly of criminals who seek to take advantage of it.
