Dahlila Beaumont

From Kokorodatabase

Dahlila Beaumont is Elizabeth's older sister. She is a sharp contrast to her sister, being tall, somewhat bulky, and very tomboyish. She prefers wearing just jeans and a t-shirt. She has brown hair and blue eyes, and it's rumored that she's married to some up-and-coming Hollywood actor. Also unlike her sister, she has big dreams for herself, where Liz is just content to live a peaceful life without becoming well-known.

For unknown reasons, Dahlila has a strong dislike towards Shirogane Jishou, this may be out of jealousy since Liz talks about her husband and Ryou almost frequently when they are together.
