In this world, there is an ancient and powerful clan. They are addicted to night, because that is the time when they can hunt to their heart's content, and people's blood is their delicious meal. They are beautiful and noble creatures, we call them - vampires!
Similarly, in a certain country, there is a swift and elegant clan. They have powerful abilities that rival the Vampires; they have a handsome appearance that is comparable to the Vampires; and they have a long life that is no different from the Vampires. Apart from that, they are no different from ordinary people. We call them - the Night Festival Clan!
The Blood Clan and the Night Sacrifice Clan signed a "Peace Treaty" at the end of thirteen thousand years. The treaty stipulates that the Blood Clan and the Night Sacrifice Clan will not interfere with each other. The Blood Clan cannot suck human blood and can only drink the blood bags provided by the Night Sacrifice Clan. Once anyone violates it, oh no, once there is a Blood Clan who violates, they will be hunted down by both races at the same time...
The founder of the Blood Clan is Cain, but the true identity of the founder of the Night Festival Clan has never been known.
Since more than 13,000 years ago, the Vampire Clan has circulated a legend: There is a girl with silver hair, golden blue eyes, and a set of double-edged knives, one called Blood Devouring and the other called Residual Flow. Countless Vampires have lost their lives to these swords;
There is a young man with black hair and red eyes who owns a magic gun named Kongwu. As long as the vampire is hit by it, no one will survive.
This is the strongest vampire hunting duo of the Yaji clan.
