The Mechanical Beast Army is a delinquent group composed of K, M, and L at Bardos High. As the daughters/creations of their school principal, they were given special rights and privileges that made them untouchable by the staff and most of the other students of their school. They attempted to challenge and destroy Seto Magami and later the rest of the Mazinger Army, as it was the task given to them by their creator. All of their attempts have ended in failure though, no matter how devious. They had a small role in Mazinger Otome Taisen only appearing for a few short instances and were usually beaten.
