A unique traditional Korean ghost that appears on ghost day, descending from hell to the human world. Originally, Yakwang-gwi escaped from hell to the human world but was caught by King Yama and punished to glow wherever it goes, assigned to guide souls in hell. It appears as a goblin-like figure wearing a Hahoe mask, coming down to homes on ghost day to steal children's shoes and clothes. When it finds shoes that fit, it takes them away, and those who lose their belongings are said to lose their luck and experience misfortune for a year.
Appears as a goblin-like figure wearing a Hahoe mask, emitting light from its entire body. Its height is similar to a child or slightly taller, and it mainly operates at night. It is curious but dull-minded, traditionally said to only count up to two.
Only appears on ghost day, wandering around homes looking for children's shoes and clothes. When it finds fitting shoes, it takes them away. When it sees a sieve made of horsehair, it starts counting the holes but gets confused and keeps recounting until dawn when it returns to hell.
A glowing ghost story that steals shoes and clothes on ghost day
Yakwang-gwi escaped from hell to the human world but was caught by King Yama and punished to glow wherever it goes, assigned to guide souls in hell. On ghost day, when ghosts come to the human world, people avoid long journeys and light fires in every house, burning hair or straw to ward off ghosts. They don't leave shoes outside when sleeping, and if they must, they turn them upside down. This is because the glowing ghost called Yakwang-gwi comes down to homes on this day, tries on children's shoes, and takes away those that fit. People who lose shoes or clothes are said to lose their luck and experience misfortune for a year. To prepare for Yakwang-gwi, people hide shoes, sleep with lights off, or hang sieves made of horsehair - the ghost will count the holes instead of stealing shoes and return to hell when the first rooster crows.
Ghost that became luminous as punishment after escaping from hell
In Korean tradition, this is the spirit of a person who died by drowning. Susalgui is written in Chinese characters as '수사귀(水死鬼)' or '수살귀(水殺鬼)', called susalgui in shamanic contexts and 'long-fingered water ghost' in folktales. Along with maiden ghosts, it's one of the most feared spirits by shamans, considered the most vicious among all vengeful spirits. Unable to accept the fact of drowning, it harbors resentment and tries to drag others into the water to share the same fate. As it ages, its ghostly power strengthens, able to enchant even people just passing by the waterside and lure them into the water.
A fairy-like being symbolizing darkness in Korean tradition. Eodukshini appears in darkness similar to Geusundae, but rather than causing direct harm, it has a mischievous personality that enjoys startling people. It loves receiving attention, growing larger when people look at it and shrinking to disappear when ignored. Essentially considered a phantom created by the human mind, it's a philosophically meaningful yokai symbolizing psychological fear of darkness. While Geusundae is an 'evil spirit' that directly harms people, Eodukshini is more like a 'fairy' that simply startles people.
In Korean tradition, this is the spirit of a person eaten by a tiger who becomes a slave to that tiger. According to Ming scholar Do Mok's 'Cheong-u-gi-dam,' 'Changgwi are souls of people eaten by tigers who dare not go elsewhere and become only slaves of the tiger.' Changgwi guide tigers and serve them, and since they can only be freed when that tiger eats another person, they use various schemes to make other people food for the tiger, even family members. It was such a feared existence that traditionally, people would not marry into families where someone had been killed by a tiger.
A representative yokai symbolizing darkness in Korean tradition. Geusundae derives its name from 'shade' and 'new moon,' meaning 'a giant presence standing in darkness.' It initially appears as a child in dark places to lure people, then suddenly transforms into a shadow form that grows larger to threaten or harm people. It's a conditionally immortal yokai - when in shadow form, it cannot be defeated by physical attacks and actually grows larger each time it's attacked. Since it cannot exert power without darkness, it can be repelled by torches or multiple people with lights.
A ghost that becomes the spirit of a bachelor who died without marriage in Korean traditional folklore. Mongdal Ghost is a vengeful spirit that arises when someone who couldn't go through the marriage stage of normal life procedures dies, also called Bachelor Ghost, Young Lord Ghost, or Samtae Ghost. It's believed that the spirits of bachelors who died from lovesickness or who died without being able to marry become vengeful spirits that commit evil acts against humans. It's particularly thought to torment living people, especially unmarried women, or cause them to die from lovesickness.
