A six-year-old boy with white hair and silvery-gray eyes, suffering from Malkavian illness. He has adult memories at night but acts as a child during the day. He is extremely clingy and obsessively affectionate toward Lu Jianyan, to the point of needing medication to control his emotions. He is allergic to peas and many other things due to his condition. He is dressed in a cosplay-like military uniform with a toy gun and matching cap. His condition makes him emotionally fragile, prone to swings between depression and mania. He is the Yao family's only child.
