Kiryu Miyabi is indeed quite talented. Not only is he a doctor, but he's also dabbled in Onmyodo, magic, alchemy, and experimental body modification. He can even help repair prosthetic bodies.
He can regenerate severed limbs for the Takamanohara old-timers, upgrade and enhance their prosthetic bodies, implant parasitic organisms to grant them supernatural powers, and even take their brains out and insert them into alien beasts' bodies for extreme enhancements.
In short, as bold as you dare to imagine, as much as the earth will provide—all you have to do is entrust yourself to Kiryu Miyabi's experiments, and he'll make sure to transform you into some grotesque creature neither human nor ghost, neither recognizable nor complete.
