It's a Chou Masouki that was created by Zets Raath Bragio, a man who was banished from the academy. It wasn't capable of being piloted by a normal person, so the brain of Shumel was transplanted into it. Like Zamzeed, it's been blessed with protection from the Earth class' Saint Grade spirit, Zamzu.
