The room itself became fully dark, not a single drop of light being able to be seen as Raven extended the realm of darkness itself into the room. But to Azrail, the one of Death itself, the darkness just felt like another ally as his senses started to spread around the room to find Raven's presence.
And thus, with a shift to the right, a tentacle of darkness that was aiming for his heart was missed. He waved the sword in his right hand forward as the darkness itself split apart, Azrail's eyes shining forth with the ability to see all souls as he located Raven moving all around, her hands filled with two swords coming from his back.
Tring!
The sound of their swords clashing was heard out, Azrail's eyes blinking as he let out a subtle mental flow out of his mind, quickly hitting Raven who took a step back. But she wasn't one to break, as she too tried to repeat the same action, releasing a small wave to counterattack the drowsiness in her mind.
