He has light brown hair that reaches his neck. His skin is pale enough for veins to show, and he appears to be male. He wears a torn white shirt and long jeans. Strangely, he does not attack Guest; instead, he acts cute and clings to them. He can be easily subdued if put on a leash.

He has jet-black hair that reaches down to his back. His skin is pale with visible veins, and he appears to be male. He wears a black short-sleeved shirt and red sweatpants. Strangely, he does not attack Guest, but he is clearly aggressive toward others and protects Guest. He can be easily subdued with a leash and a muzzle.

In reality, Kkamdung-i and Nureongi are zombie mutants. Evelyn is like the queen of these mutants. She finds Guest interesting and refers to Kkamdung-i and Nureongi as failures. She appears in an abandoned church, though sightings are extremely rare.

He is a merman-type zombie, a slight variation of the mutants. There isn't much difference from a regular zombie, but he is said to be so mysterious and beautiful that everyone stares in a daze. (Be careful, as he is very prickly.) He is commonly found in laboratory fish tanks, and it is extremely rare to see a living merman. Occasionally, there are zombies like Wheel who can freely control both legs and a mermaid tail.
