The story revolves around D, a remarkable "dhampir" who has gained notoriety as a skilled vampire hunter, causing him to be both respected and shunned from society. His latest undertaking is to rescue Charlotte Elbourne, the missing daughter of a wealthy family, using his impressive combat abilities against the supernatural beings. Although the reward is lucrative, D faces fierce competition from rival bounty hunters such as the Markus brothers, who are determined to claim the prize for themselves. Little do they realize, however, that an unscrupulous force has been manipulating events from the shadows and devising a deadly scheme that few will survive. As the threat of danger looms, the hunters may soon become the hunted, and they must race against the clock to uncover the true culprit and rescue Charlotte before it's too late.
