The only individual in Arzenal who utilizes Mana and serves as Jill's right-hand person while taking rules very seriously. It is believed that this person views Normas as objects or non-human entities. There are indications that they work for the Rosenblums, and their role extends beyond being second-in-command to also managing the island's overall operations as its caretaker.
