Gangnam Dokkaebi

Someone has made a wish to kill all students. The Dokkaebis, man-eating creatures who are bound by rule that they can only act to help people, are now allowed to hunt down students... Students are going missing left and right and Ki-mok, a student who is also one of only 44 people in the world with the "Blood of Gold," is now in a fight for his life against these supernatural beings that vie for his blood to empower themselves.
