[quote]Huh. Are these Red Laces magic then?[/quote]
Yes. They have magical properties. This is what makes them impervious to damage so they can't burn, rip, or tear. While in Red Fury, the Red Laces are giving magical powers to the wearer.

[quote]Legit question: if you cut off one of her hands while she's wearing the Laces, what happens[/quote]
The magical abilities she has acquired would go away. You need both of them to enter Red Fury. She's probably retreat from the battle.

I'll be editing Red Lace's bio here soon.

EDIT: Re-read Red Lace's bio. It is 'finished' but can probably be edited in the future to make it look better (needs to be revised and whatnot).
