Shiki

Shikis (Homopteryx Deinodontus Shiikii) is a subspecies of vampire that originated from the anime series of the same name. They have black eyes containing red irises, giving them frightening appearances. They are pure evil blood-sucking immortal creatures of the night. They can suck blood and have the ability to turn their victims into shikis. They, however, can be harmed by religious artifacts.
