Kishi

The Kishi are monstrous creatures from the myths of Angola. They resemble humans with a hyena face on the back of their heads, often growing out their hair or wearing a headdress to hide their second face. They use their charm, and appearance of a seductive male to lure in victims, namely pretty young women. They then take their victims aside to reveal their horrifying nature. They feed on the fear released in this moment, and then consume the flesh of their victims. They are strong and smart and bite with more force than a crocodile, easily killing with just one bite. They can be killed through normal means and are repelled by fire.
