세모괴(세상의 모든 괴이)

A yokai that frequently appears in the western regions of Japan, read as 'Ushioni' in Japanese and directly translated to Korean as 'U-gwi'. Its most famous form is that of a cow's face with a spider's body and legs, but depending on the legend, it can also be depicted with the face of a monkey, human, or oni, with a cow's horns and a tiger's body. It hides in the water and then leaps out when a person approaches, devouring their shadow. It is said that anyone whose shadow is eaten dies immediately. There are also cases where it disguises itself as a human to attack, but its reflection in the water reveals its yokai form, making it easy to recognize. As mentioned in the post about the Nure-onna, it is known as the Nure-onna's husband in western Japan. In the early Edo period Joruri (puppet play) 'Ushigozennohonnji', a variant called 'Ushigozenn' also appears. Being such a famous named yokai in Japan, it frequently appears in various forms, as shown in the attached image. Naruto - 8-Tails Gyuki One Piece - Saint Jaygarcia Saturn Digimon Series - Kyuukimon

Meaning 'wet woman,' this yokai from the Edo period was said to appear in rivers and seas. It has the body of a snake up to 300m long and the head of a wet woman. Depending on the legend, it may have arms or its upper body entirely depicted as a woman, like a Naga or Lamia. It usually disguises itself as a human holding a baby, asks passersby to hold the baby for a moment while it rests, then hands over the baby and disappears. The baby it hands over gradually sticks to the person and becomes heavier, eventually immobilizing them. The Nure-onna then reappears, wraps its long body around them, and devours them. In the western regions of Japan, it's not the Nure-onna but its husband, the Gyuuki (a yokai with the head of a cow and the body of a spider), who appears and devours the person. There is one way to escape from the Nure-onna: wear gloves when receiving the baby. When the baby starts to get heavy, take off the gloves and run away.

With the characters for 'dry' (고), 'thin' (수), 'like' (여), and 'lacquer tree' (칠), it means 'skinny legs look like they've been lacquered black'. Gosuyeochil is recorded in the Veritable Records of the Joseon Dynasty, Volume 197, the 4th entry on November 25th of the 17th year of King Seongjong's reign (Gansin Year), and in Yongjaechonghwa. The story is as follows: A ghost entered the house of Lee Du, who had become a left-rank official in the Ministry of Personnel. The voice was that of his aunt, who had been dead for 10 years. The ghost's upper body was invisible, but below the waist, it wore a paper skirt. Its legs were thin, with no flesh, only black bones. When asked why its legs were only bones, it replied, 'Isn't it natural since I've been dead for so long?' The ghost demanded meals every morning and evening, and anything it craved at the moment. If its demands weren't met, it would rage and cause a disturbance. If they were met, although it was not seen picking up chopsticks or eating, the food miraculously disappeared. Lee Du tried various methods to get rid of this ghost, but to no avail. Shortly after, Lee Du himself died of illness.

The characters mean 'well', 'same', 'cow', 'cry'. It translates to 'a well cries like a cow,' and it's said to be a legend passed down throughout the country since the Goryeo Dynasty. The most widely known among them is the story experienced by An Jong-yak, the maternal uncle of Seong Hyeon, who wrote Yongjaechonghwa, when he became the magistrate of the Imcheon region. Imcheon had a custom of worshipping ghosts. When those who moved into the government office kept dying, the villagers called it the Goblin Forest and abandoned it. When An Jong-yak, who had been appointed as the magistrate, tried to enter the office, the villagers tried to stop him, but he didn't listen. Instead, he burned down all the shrines around him that worshipped ghosts. To the south of the office, there was an old well where villagers believed there were ghosts and held rituals. When An Jong-yak ordered the well to be filled in, a sound like a cow crying was heard from the well for three days. The villagers then asked him not to fill in the well, but An Jong-yak pushed ahead, saying, 'What's the big deal if a well cries?' After that, all evil spirits disappeared.

During the Joseon Dynasty, in Sogong-dong, Gyeongseong, a man named Shin Mak-jeong bought a house. Inside the house lived a ghost that could speak but whose form was unseen. The ghost served the homeowner like a servant, calling him 'Master.' However, it constantly demanded food, and if not given, it would become enraged and act violently. Furthermore, it followed the owner everywhere. Every night, when the owner and his wife lay down on their bed, the ghost would crouch beneath the bed and laugh. One day, the owner, curious about the ghost's appearance, asked it to draw its own likeness. After a while, a hideous image appeared on the wall: a creature with two heads, four eyes, tall horns, drooping lips, a crooked nose, and a face and eyes that were red. Seeing its terrifying appearance, the owner grew to dislike the ghost. He secretly asked a Taoist priest for a way to kill it, who advised that if the ghost were fed roasted field mice, it would die. Some time later, the owner gave the ghost roasted field mouse meat. Upon receiving and eating it, the ghost wailed, "I am going to die now," then left the house and never returned.

The first monumental yokai is Kkeomeoksari, a mascot character that gained immense popularity for its cute appearance in the Netflix drama 'Donggong'. The legend of Kkeomeoksari was reported not too long ago in 2008, with a woman surnamed Shin reportedly witnessing it in the 1960s. Past midnight, as Ms. Shin was passing by a winding bend in the mountain path after shredding barley at the mill to return home, a pitch-black, human-shaped figure the size of a puppy suddenly emerged from the bushes and ran around frantically, repeatedly saying, "I am Kkeomeoksari, Kkeomeoksari, Kkeomeoksari, Kkeomeoksari." Ms. Shin, who had always had strong spiritual senses and had seen goblins multiple times before, was not frightened or intimidated. She threatened to kick it if it kept blocking her path, so it moved aside slightly. However, it continued to follow her home, repeating the phrase, "I am Kkeomeoksari, Kkeomeoksari, Kkeomeoksari, Kkeomeoksari." Shortly after, Ms. Shin crossed a stream and shouted, "If you have the guts to follow me this far, then come on!" but it did not follow any further.
