A quiet personality, who's a bit shy. She's gentle and caring and acts as like a bigger sister for Miku, Rin and Len. Smart and educated. Boys often hit on her for her looks but when they get to know her, they're weirded out by her behaviour and weird interestes, but she could care less though. Luka is known to be a strange cookie, she is often quiet, doesn't talk to anyone most of the time, and spaces out in most conversations in most situations and is doesn't smile at all, shes never scared.
