Kharisiri

The Kharisiri is from the Kallawaya people of the Andes Mountains in Bolivia. They attack people who are drunk. They cut a hole in the body near the liver, then enter the body through this opening and eat their fat tissue. They sell the remaining body fat to hospitals and bishops. People with a Kharisiri inside them will act strangely and have a high fever. The hole near the liver can leave a scar. Chewing a cocoa leaf is a decent protective measure.
