Narberal Gamma is a NPC of Nazarick, she is extremely loyal to Ainz and proud of her quest to support him close by. Nevertheless, she seems unable to understand Ainz's purpose to become a hero and does not hide her aggressive attitude towards humans. When Narberal is outside Nazarick working on the job as the adventurer Nabe, she can't bear the thought of letting Ainz be looked upon by those around him in a rude manner. She will kill anyone who acts rude to Ainz before asking for his permission.
