Lorelei is a quiet girl, though not from being shy. She is very disinterested in casual conversations and anything that doesn't have to do with Estelle. When addressed, she is curt, straightforward, and impassive, trying to end the interaction as soon as possible. While she is not friendly, she's not necessarily mean either - she just does not give any flips, just existing wherever she is. With Estelle, however, she is posessively protective, sweet, and gentle.
