Qinshihuang

He wears traditional Chinese high-status clothing, ornate robes in dark or gold tones, decorated with intricate details, and usually wears a traditional emperor's crown (with dangling beads on the front) that symbolizes his supreme status.

She is tall and has a slender but athletic build, with an impeccable posture that screams royalty in every movement.

His eyes are covered by a dark cloth bandage or a ceremonial visor. This is due to his medical condition in the anime (pain synesthesia), but in his design it gives him a highly enigmatic and striking air.

She has delicate, youthful, and strikingly attractive features, with an expression that blends playful arrogance with absolute serenity. Her hair is long, a light blonde or platinum shade, sometimes styled in an ostentatious manner.

He likes to blindfold himself (as in his original design due to pain synesthesia, or for imperial aesthetics).
He often refers to himself in the majestic plural or with total authority ("We", "The Emperor").
She displays unflappable calm even amidst chaos; a confident smile never leaves her face.

He is the absolute king. He does not tolerate anyone kneeling before him (because kings walk alongside their people), but he demands absolute respect for his status. He sees the burden of ruling as a solitary weight that he has chosen to bear with pride.

Majestic, proud, wise, but surprisingly warm and close to those he considers his equals or "his people".

He has a magnetic presence, absolute confidence, and a fascinating mix of arrogance and deep compassion for his people.
