From ancient mythical creatures like ploos, orchs, and ghosts originating in distant Stories, to mechatrons, magical girls, and masked heroes born from anime and games—the variety is endless. This phenomenon is known as "imagenesis." "Imagenae" is the collective term for all sapient beings born from fiction, and they coexist with humanity in the present world.
