Ruby Zhao is a member of the wealthy Zhao Family. She is Daniel Yoon's advisor and cousin.
Ruby Zhao originally had blonde hair (that was revealed in a flashback) but then she dyed her hair pink, it's long and she has aqua green eyes. She often wears office clothes and heels.
Ruby Zhao bears a well-endowed complexion and is initially shown as a very firm, serious girl. She always acts somewhat grumpy around others, even Daniel. Ruby has a certain appreciation for Henry Pomeroy (presumed love interest), who seems to be the only character so far that causes her to show a more kind, childish, even flustered version of herself.
