Mari

Mari is the heir to the Kounat Royal Family, which was destroyed when Ashtaroth lost control of the Aernas Hammer, a legendary weapon only usable by the "Geas" imposed on the Kounat Royal Family, making Mari its "key." Mari was put in an escape pod which failed to activate properly due to the explosion that annihilated Kounat, but was saved by Void for his own purposes which are still unknown. The explosion caused the pod to malfunction and was put in hibernation mode in order to protect the passenger, though how she awakened is still unknown.
