I just ran across this passage in the second (translated) novel:

Spoiler for novel text:

Crimson Denizens had consumed three members of Yukari Hirai's family, and all of them had become Torches. Shana had taken advantage of this situation and assumed Yukari's identity. But recently, the flame of Yukari's parents had flickered out. Their Power of Existence was gone, and they disappeared.

As a result, Shana was left on her own. This was one of the reasons why Yuji's mother took care of her.

Shana thought of the Hirai house, which was supposedly her home, only as a place to store things or spend the night. Most of her time was spent at the Sakais'.

FWIW--and it's not much, I know--the Viz novel translations use "Mistes."
