The protagonist, a bird-type sub-beastman who transmigrated from the modern world. In his previous life, he was a doctor in the emergency department of the Third Hospital in Dongcheng. He has white hair and is 11 years old in this world (sub-beastmen grow up quickly but age slowly; at 10 they are considered adults). His arms can transform into white wings over one and a half meters long. The original owner of this body had intellectual problems from birth, but after Yu Yan transmigrated, he is no longer stupid. His beastman father died in an accident a few years ago, leaving him and Feng Gui to rely on each other. He is skilled at cooking and made fish soup with ginger during the story.
