Shizu Onuma  

Griselda is a close friend and loyal servant of Agito Makishima. Despite being female, she became the first Griselda to command the Libertus of the Zeus Thunderbolts organization. Her grandfather Yohei had been a devoted retainer of the Makishima family for many years before meeting Agito. It is unclear what happened to her parents, but Yohei treated her as his own daughter. Griselda is known by her battle form name, Griselda, when she fights as a Zoalord.
