Grasshopper Manufacture
Suda's studio Grasshopper Manufacture has borrowed settings and characters from "Moonlight Syndrome" for some of their works, including "The Silver Case" and "Flower, Sun, and Rain". Suda also hired a writer to work on "The Silver Case" after reading their work in "Twilight Syndrome Truth File", a guide retelling the incidents of the first two games from the perspective of fictional journalists reporting on it.
