So when he sees Sougo Kijima, a Bestia who lets his instincts run him wild, there's something that makes the doctor snarl. Sougo Kijima is one of the directors of the hospital where Dr. Miyaji works. And to make matters worse, Kijima has designated Dr. Miyaji specifically to be his practitioner! What is it about him that Miyaji reacts to so much?!"
