Human beings are not the only people that lived in this world. There are also called"humpire" who lived with humans. They are the new vampire generations, they are not afraid of sunlight, they can suppress their selves from wanting human blood.
They only drink blood once every red full moon, to maintain their strength.
Every full moon, the elderly humpire took any human blood and poured it into a coffin, where the"dark lord Nappun" is lying. Hoping they got the right blood to wake up the sleeping humpire.
Nappun is the most powerful among the vampire generations. He slept over 500 years ago when the first "sarang" succeed to make Nappun asleep.
The only way for him to wake up is the blood of "sarang".Sarang or the chosen sacrifice is the person who has a symbol that looks like a sword on his/her body.
Sarang is the only way to awaken the dark lord.
So, the elderly Myungsoo and Chanyeol who lived on the isolated island of Jeju ordered the shadow humpire to find and bring the sarang
"Shadow humpire are the humpire that served the elders. The place where the elderly lived is called "Tamra."The elders are the powerful, ruthless ruler of humpires nation. And they worship Nappun.
They thought that the waiting of sarang is over...
