Dr. Akira Miyaji specializes in treating Bestian patients at the general hospital and is a Bestia himself. Although things started out rough with the hospital's manager, Sougo Kijima, the two managed to find peace and settled down, even starting a family. The Bestia branch of the hospital being understaffed as always, Akira decides to go back to work. Just as he returns to his duties, he learns that a new physician would be sent from the non-eared branch to help Akira with his workload. This is the first time a non-eared human doctor would be assigned to work in the Bestia branch. What will all the patients think? And more importantly, how will Akira handle it all?
