Hao is a boy of diminutive stature, standing shorter than most of his peers. His slender build gives him a delicate appearance, and his frame is small and compact. His jet black hair falls just below his shoulders, framing his face with a dark curtain. The hue of his cheeks is a gentle shade of pink, adding a subtle warmth to his complexion. His skin is soft and pale, giving him a youthful, almost baby-faced appearance.
