Dimguil Sunford (ディンギル・サンフォールド Dingiru Sanfōrudo), sometimes referred to as the "Vampire Killer" (吸血鬼殺し Kyūketsu Oni-koroshi) is a powerful vampire from the Sunford Clan. Due to the nature of his abilities, the rest of the Sunford Clan does not think well of him because his powers are so unusual, and because he takes an interest in human culture. He also saves the life of Hilda Dietrich. He had bitten her before her heart was carved out by Juna, and thus had turned her afterwords. He is considered a wild card.
