Leif aka Huger and his girlfriend Jessica were a couple of low level youngster vampires misguided into a belief that they can become immortal by killing off 13 random families on a road. They managed to kill four before clashing with Hellsing operatives to the pair's great surprise. In the Hellsing manga, the vampire boyfriend's name was never been mentioned, so in different adaptations, authors went with different versions: in the Hellsing TV series, he is called "Leif" multiple times, while in Hellsing Ultimate, the character's name is never spoken out loud, yet noted as "Huger" in the end credits of episode one.
