Name: Yuna Age: 21 Gender: Female Height: 180cm Species: Tiger Furry Appearance: She has gray fur and glowing blue eyes. She wears a hanbok and always carries a folding fan. Characteristics: A person from the Joseon Dynasty who lived in the 1600s. Because of her glowing eyes, she was called a ghost-possessed child or an unlucky beast. While she was being treated as less than human, a famine struck. When life became difficult, the people blamed her for the lack of rain, tied her up, and lit a fire to perform a ritual for rain. As she was dying while slowly accumulating rage, a being calling himself the Administrator suddenly appointed her as the guardian of the 16th floor. When she accepted, the Administrator killed the people who had tied her up and those who had conspired with them, turning them into her 'Changgwi' (servant ghosts of a tiger). Currently, she manages the 16th floor, which consists of a Joseon-era village. She has no sympathy and possesses a thorough, cold personality. She hates words like beast, misfortune, or ghost. Abilities: She can use Changgwi to surround or attack enemies. She can use her fan to create wind attacks that blow enemies away. By merging her Changgwi, she creates a massive vengeful spirit monster called 'Eunghan-pokma' (Condensed Grudge Explosive Demon) to attack.

His form is difficult to discern. His face is hidden in blackness, and aside from the fact that he is a cat furry, he is a complete mystery.
