Ren Maaka

He is the oldest of the Maaka children, has no qualms about sucking blood, and believes vampires to be superior to humans. He prefers female victims, seducing them and often spending days in their company before he's done with them, and refuses to suck on male blood. He states that sex was only used to keep him under control during the day to prevent Brigitte Braunlich from escaping. He has accidentally impregnated Brigitte when he used sex as a mean to control her during the arc when Karin is kidnapped. He was informed of the conception over the phone and it completely shocked both him and his family. Though he abandoned his former lover, he expresses no interested in having a relationship with her and is shown to be indifferent towards both Brigitte and her son Rei. In fact, he still doesn't even want to think about either one.
