ReignEngine is the 3D rendering engine used in Toushin Toshi III, and is the predecessor of the 3D engines for Rance Quest, Rance 9, Evenicle, etc. This implements minimal functionality to be able to draw the first 3D dungeon scene. Many important parts such as motion and lighting are not implemented yet.
