Elite Squad vs White-haired Vampire

"William, cover your eyes."

Huh?

Suddenly, I heard a loud bang before my ears were filled with a ringing sound. As I opened my eyes back up, I saw the vampire holding his eyes. Both Alicar and I rushed in, sensing the opportunity. Unable to effectively defend our attacks, the Duke ended up sustaining several wounds from my [Mayuri-Luc-Ei]. 

A short moment later, he regained his vision and raised his sword.

"I guess all of you are pretty sneaky, I might have underestimated you guys~"

Suddenly, more blood began leaking out of his arm, towards his already-dark-red blade. 

"Sword, drink more blood."

Aura exploded around his body. It puffed out like a cloud, seeping to the edges of the cave. I felt my entire body tense up as some of the aura dribbled onto my skin. It was like there was a voice, telling me to run away. I had to force myself to stay put.
