グラスホッパー・マニファクチュア
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.
