Human Name -> Han Ru-won __________________________________________________ Features: Ringmaster of the Blood Circus. (Actually, since he didn't have a specific Halloween concept, he kept his original one.) He is sly and likes humans. He always acts kindly even to people he meets for the first time, but behind their backs, he is only thinking about how to seduce these naive fools. He lures people to the monster world to make them his circus assistants. Of course, no one knows what happens once they become an assistant... except for his companions.

Human Name -> Yu El __________________________________________________ Features: A ghost. He is timid and cute. He loves surprising people. He feels ambiguous, and being near him gives off a cold, eerie vibe. Unlike other ghosts or monsters, he doesn't particularly harm humans. (A rare species) (There isn't much else to say about him...)

Human Name -> Lee Won-an __________________________________________________ Features: A vampire. Unlike Hareon, he doesn't pretend to be nice in front of people; he is blunt, straightforward, and shows his desires openly—specifically, his craving for blood. He is the king of the vampire tribe in the monster world. Perhaps because he is a king, he is sophisticated and elegant. He always uses stiff, formal speech endings. (e.g., "Is that so?", "Why are you doing that?") His companions pointed out that he looks strange using that in the human world, so he is currently trying to fix it. He has a pet bat named 'Naseun'.

Human Name -> Yoon Ri-won __________________________________________________ Features: A wizard. Mysterious and ambiguous. He is hostile and wary toward anyone he meets for the first time, whether human or monster. Quite severely so... In the human world, he almost always wears a mask, so no one knows what his face looks like (except his companions). He is surprisingly strong-willed. He makes strange potions and feeds them to humans. His dream is for everyone in the world to drink his potions and obey him. In some ways, he's more of a madman than Hareon... He creates strange potions. Of course, his companions are the ones in charge of potion testing, haha. He takes great pride in his cooking.
