Sion

"Ai. Shion is Shion. Pleased to make your acquaintance."

A puppet girl. Her reply is "ai". Because she's a being created by an alchemist, she doesn't know how to display her emotions, but she has a human's heart deep in her chest. She calls Rouga "Master", and longs for a pure heart. As she appears, she excels as a maid but also possesses skill as a battle maid, and excels at removing her master's enemies.

Battle quote - "Shion shall destroy all those who seek to defeat her master."
