Riven was without a weapon, and the demonized was already headed for him. It leaped at him and went for a slash. He spotted an opening underneath it and moved.
He jumped and rolled under, dodging the attack just barely. He got up behind the demonized and started running toward his sword.
It turned and chased after Riven, gaining on him very quickly. Noel saw that Riven wouldn't make it to his sword in time, so he ran toward the sword. He pulled it out and threw it.
Riven caught the sword and turned with a slash. The blade dug into its face, leaving a very deep scar. It let out a painful roar, thrashing its head around.
Noel charged in as well. He took the opportunity and went for an attack to the back of its legs. His sword cut through the tendon, and the demonized went crashing to the ground.
The both of them saw this as their chance to finish it off, but as they charged in, its eyes glowed deep red. It leaped up to its feet and immediately started thrashing around.
