"I don't understand the feelings of the weak. The law of the world is survival at its fittest. Its how the weak are weeded out. It just means those people that died were too weak. Its only natural for the weak to perish." - Esdeath

Esdeath has wielded one of the 7 fragments of the Original Witchblade: Witchblade Arctic 

Witchblade Arctic increases Esdeath's Teigu Demon's Extract into unfathomable proportions. The use of the Witchblade enhances her Ice ability that can't be cut or melted easily. These ice are unmeltable, even in arctic levels. If someone gets cut by the Witchblade's sabre, it'll freeze the opponent in about 1.5 seconds.
