This is me retconning any mention of
Lizzie being an only child, sob. I just found out she has a big brother who looks and acts like Elliot from Pandora Hearts. (THANKS YANA.) Her male relatives are so tsundere, but at least we know where Lizzie got her touchy-feely "sooo cuuute" thing from. (Daddy is the bestest.)
Oh and there are zombies, too, but that's less important.
