A Tale of the Secret Saint Novel Volume 4 was written by Touya with illustrations by Chibi.

The yellow-speckle fever is running rampant in Sutherland, and the townspeople are suffering. But even as the disease grips the populace, they are still too distrustful of the knights to accept their help. Maybe what they need is some good old-fashioned fairy-tale magic. Can the “Great Saint” get through to them and provide the cures they need—healing both the disease and the scars of the past?
