Divine Beast Surgeon

Phantom beasts that were once protected humanity and worshiped as gods are losing their power due to the development of human technology. The phantom beasts that have lost their power become afflicted by disease, and eventually die. "The Staff of Asclepius" was established to save such beasts. They call themselves "phantom veterinarians" and use medical techniques to treat diseased phantom beasts. The full-fledged medical high-fantasy, with a detailed and realistic world view, is created by an active surgeon Haruka Minami, supported by powerful artwork from Kei Deguchi, opens here!
