Tianzi (天子)
Age: 13
Height: 138 cm / 4'8" (original design, 2008); 152 cm / 5'0" (redesigned, 2011 onward)
Real name: Jiang Lihua
The young empress of the Chinese Federation, though "Tianzi"—meaning "Child of Heaven"—is just her traditional imperial title rather than a personal name. She's essentially a figurehead; while she holds the ceremonial position of emperor, actual political power rests entirely with the High Ministry. In practice, she functions as a living symbol of the state and national unity rather than a ruling authority.
She first appears in season two, where she becomes involved in diplomatic talks with Kaguya Sumeragi, before Kaguya's return to Area 11. Given her position as a young woman in a ceremonial role while real power operates behind the scenes, these negotiations suggest deeper political maneuvering at play.
