Sargatanas

A tall and strict female demon with brown eyes and tied purple hair except for two long strands that almost reach the floor. She is Astaroth's assistant and spends most of her time chasing him down and forcing him to return to work. Despite her calm and collected appearance she is actually an open sadist, frequently punishing Astaroth violently or threatening to shoot him with her twin pistols, especially when he draws attention to her flat chest. Her position in Pandemonium's finance department allows her to maintain a secret stash of money to repair any damages caused by her violent methods of forcing Astaroth to actually do his job. Despite her violence she also enjoys cute things similar to Azazel, though unlike Azazel she prefers to keep her hobby a secret. She has a secret crush on Astaroth and becomes embarrassed whenever he says anything nice to her.
