フェリド・バートリー

Age: Unknown

Ferid is a seventh progenitor among all the vampires. He is the one who killed Yuuichirou's family, thus fueling Yūichirō's desire for revenge against all vampires. 

Ferid is chatty, happy, enthusiastic, playful, and sneaky. He is often described as unpredictable. He often says things to incite someone's temper but then says he is just kidding. Ferid enjoys irritating Krul and Mikaela to a dangerous level, and he has a great deal of fun teasing Mika as well. He is infamous for his eccentric behavior and tends to cause "interesting" things to happen, according to Crowley.

Ferid is self-serving and traitorous to serve his own ends, and he really appears to be assisting the humans somehow. He uses blackmail to stay Krul's hand when she desperately wants to see him dead.

On the outside, Ferid acts kind and polite. However, he keeps many secrets and tells many lies. He is sadistic and enjoys manipulating others in order to torment them. He immensely enjoys crushing the hopes of human children and watching their expressions become filled with despair. He says he wants to hear them scream. He prefers the blood of beautiful boys and girls. Regarding age, he claims the 16-year-old Mika is just barely within his preference range. He would like Mika to drink human blood and stop aging as soon as possible, and he frequently brings up the topic when he is alone with him..

Toward his own supporters, Ferid may say carelessly cruel things. His true objective is a mystery, even to his closest followers. He appears to be at work manipulating many things behind the scenes.

He considers the humans to be ugly, insatiable cowards. He also mocks the vampires' boundless arrogance.
