I guess Noblesse was really popular in Korea. This is from the game Dragon Nest. An action role playing game.
Might be a little too late since it was from July 2013. Maybe you've seen it yet maybe you don't.
Weapons featured are the Amore (Karias), Legasus (Gejutel), Blood Witch (Rozaria), Izarok (Ludis).
Not sure about the soul weapons on the girls on the far left and right.
