Yang Guifei is a Servant in the Fate series based on the historical Yang Yuhuan, a renowned imperial consort of the Tang Dynasty. In 740 AD, Emperor Xuanzong was captivated by her unparalleled beauty and exquisite dancing skills. She was designated as a Taoist priestess before being officially conferred as imperial consort in 745 AD. In the Fate universe, Yang Guifei possesses the unique ability to perceive imaginary space through hearing rather than sight. She encountered Van Gogh's Noble Phantasm, which creates objects with mass from the massless imaginary number space, causing contradictions that distorted perception and damaged minds. Her historical significance extends beyond personal influence—her family gained unprecedented power, with her cousin becoming prime minister, though this ultimately contributed to political corruption. She met a tragic end by hanging at Mawei Slope during An Lushan's rebellion, an event immortalized in classical literature.
