Hermina was a former member and chief researcher of the Elgos Order, an organization whose main objective is to guard Dracula's sealed material possessions, as well as the grimoires that contain the history of all heroes and battles that had been held against him throughout the years. She was the one responsible for the method to enter the grimoires.
According to Seward, one day she suffered a change of mind and destroyed her research on the grimoires, also taking several of them with her, including a catalogue containing an evil version of Soma Cruz, and disappeared.
She later reappeared within the grimoires after the representation of Soma within the grimoire attacked the group. After a short conversation, Hermina and Soma retreated.
