"Devil's mark?" The Six-armed Snake Demon crossed her arms and looked down at Grace, hissing, "I see. A poor little creature caught in the web woven by a devil's conspiracy. How much of your current thoughts are truly your own? And how much are the whispers of that devil in your ear? Meeting Lord Gaven is your good fortune, as his power is one of the rare few able to sever such marks. Without cutting it off, as long as that devil lives, you'll have no means to escape this entanglement; it will draw you into hell, to join his collection of trinkets."
Ophelia's words were undoubtedly demonic murmurs.
She was neither helping Gaven out of kindness nor assisting Grace. She simply wanted to savor the complex expression of a toy played to its breaking point, to pull her into her own ranks; an additional little plaything by her side was not a bad choice.
