She is the daughter of Ei daren and his British mistress. She kills her father after she learns that he has been colluding with Ginga Kanashima.
Yili is a fairly icy individual; however, it is hinted that she has a soft spot for Seiichi Kugi, with whom she pretended to be in a relationship with for five years.
Yili has black hair pulled back into a thin ponytail, and wears a qipao that is completely white save for the blood-red breast. Her fair skin and blue eyes (from her white mother) set her apart from her fellow executives.
Her half-brother Lihuang Ei has used her blue eyes as a racial, derogatory means of insulting her.
