Okay, I am just going to lay it out right now:
Is the girl/boy in White Brick Barisol?
Yes, I know mothy has stated that White Brick is not Evillious, but he could be throwing us for a loop.
Anyways, the speculatory proof.
1. I was reading a forum post about the new album and someone mentioned that names that end with "ru" normally are gender-neutral, so I believe Levia's Barisol is the boy in White Brick, and Behemo's Barisol is the girl.
(Random Thought: Did the female Barisol kill her parents? After all, WBaBMG mentions that the girl had dead parents and was wandering the street. Could this also mean that she had HER?)
2. (Cont. of Random Thought) Is the ability to see another you in the mirror caused by the fact that they had Malice/HER? Behemo couldn't see Levia until he killed his girlfriend, and I think that Levia used the magic of Science to meet Behemo.
3. In WBaBMG, she mentions that "She had a son who looked like him" (refering to the boy in the mirror). The boy in the mirror is represented by Len, as shown in a part of the song with him speaking. It would not be too far fetched to assume that the boy had a son who looked like the girl.
Respond with your thoughts please. Rember, this is just my SPECULATION, I could probably be wrong
