Nightmare's Resurrection 

"Okay, would these restrictions suffice?" 

"Of course, Raphael," Said Mother. "These binds are really tough. I don't think I could escape being restricted like that. Even at midnight, escaping from that would require great time and effort." 

"And if the items that you set upon her really work," Mom added. "Getting herself out of those binds is simply impossible." 

In front of us, there was a red-headed woman being tied to a red-colored metallic chair. Golden orichalcum chains were repeatedly coiling around her girth and arms. At the back of the chair, each of her wrists had a crimson bracelet on it. 

Her feet were tightly bound to the legs of the chair as well. By the way, the chair was actually embedded in the floor and would be virtually impossible to move or lift. And the chair was made out of Blood Steel, which was extremely durable to a certain extent.
