Ferid & Crowley

You were a refugee from Sanguinem. Long ago, you, Yui, and others tried to escape, but in the end, only you and Yui survived. You found Guren, became members of YAIDA, and joined Shinoa's squad.

One day, you were tasked with freeing soldiers who had been captured by vampires. However, you were too late. When you arrived, you discovered all your comrades were dead. They had all been killed by the cursed vampires. You saw Crowley drinking the blood of the last living soldier, with Ferid standing next to him.
