Meanwhile, Nell has been working diligently to secure alliances in the demon world. Out of nowhere, she’s attacked by a mysterious group of people clad in black from head to toe. As she desperately tries to fight back, both her endurance and magic drain away, leaving her in a desperate situation with no escape.
