What would it be like to be a twelve-inch-tall girl among normal humans? To make things worse, what if you couldn't remember who you are or where you're from? That's Tierza Velvet's problem.

With her new friends, Tierza has to find her past, and quickly, because an unknown poison is weakening her.
