Jiro Saburo Sai

Tradition: Japanese Mythology
Alternative Names: Jiro Saburo’s Wife, Demon Wife
Category: Demon


The Myth

Jiro Saburo’s wife was a cruel and intensely jealous woman who eventually transformed into a terrifying demon after her husband abandoned her. Before her transformation, she was already known for her vicious temper and unbearable jealousy, particularly toward the female servants of her household.

She became furious whenever a female servant even looked at her husband or spoke with him. Her constant abuse eventually drove all of the servants away. As the family’s wealth declined, her behavior became increasingly bitter and violent, and she refused to listen to anyone who tried to correct her.

Jiro Saburo finally warned her that if she did not change, he would leave the household. Enraged, she attacked him and choked him, declaring that even if she could not kill him while alive, she would kill him after her death. She accused him of wanting to leave her for another woman.

Jiro Saburo eventually disappeared. When his wife discovered that he had fled, she became consumed by hatred. She searched everywhere for him, repeatedly swearing that she would never allow him to escape her. During the day she wandered about looking for him, while at night she wept and repeated that she hated him for abandoning her.

After forty or fifty days, she had become almost unrecognizable. Her eyes were bloodshot, her cheekbones protruded, and she had become filthy and disheveled. She refused to wash or eat and behaved so strangely that the villagers became afraid of her.

Then her house suddenly became silent. At midnight, however, the villagers heard her speaking inside as though someone had come to visit her. The following day the house was silent again. Several brave villagers eventually looked through a hole in the wall and saw something horrifying.

Two horns had grown from the woman’s head. Her mouth had split almost to her ears, and fangs had emerged from both sides. Her eyes shone fiercely, making her indistinguishable from a demon. Terrified, the villagers abandoned the neighborhood.

People who knew where Jiro Saburo was hiding hurried to warn him. He remembered his wife’s threat that she would return from the dead to kill him and feared that she would find him.

A traveling monk named Gen’ō was staying nearby. He was the famous monk said to have destroyed the Sesshō-seki, the Killing Stone. Jiro Saburo went to him, explained everything, and begged for help.

Gen’ō told him that his wife’s obsession had transformed her into a demon. She had entered the demonic realm with nothing in her heart except the desire to kill her husband. According to Gen’ō, six days had passed since her death, and that night she would receive permission from the Sixth Heaven to travel through the three thousand worlds in a single night.

Gen’ō instructed Jiro Saburo to return home. There they found the corpse of his wife lying in the ruined house, its face already resembling that of a demon or rakshasa.

The monk stripped Jiro Saburo naked and covered his body with the Nio Hannya Sutra. He then ordered him to climb onto the demoness’s back, wrap his arms around her neck, and never let go.

Jiro Saburo obeyed despite his terror. As night fell, Gen’ō left him alone and told him that his survival depended entirely on holding on. Jiro Saburo remained clinging to the corpse and continuously recited Buddhist names.

In the middle of the night, the demoness’s cold body gradually began to grow warm. Suddenly it rose to its feet. Its eyes shone brightly, flames came from its mouth, and it spoke.

“Oh, how wonderful! Tonight I have been granted permission to kill you. Now, let’s see where you are.”

The demoness ran away, carrying Jiro Saburo on her back. She raced across mountains, rivers, and valleys like a bird flying through the night, searching everywhere for him. Jiro Saburo realized that this was his only chance to survive and held onto her neck with all his strength, determined not to release her even if his arms were torn away.

The demon searched throughout the night but never realized that Jiro Saburo was clinging to her back. When dawn approached, she returned home in frustration.

“I’ve searched so hard, but I can’t find you. I suppose you must have died before me.”

She laughed bitterly, lamenting that she had failed to find him. Immediately afterward, the demoness collapsed to the ground, and Jiro Saburo lost consciousness.

At dawn, Gen’ō returned and woke Jiro Saburo. Seeing that he had followed his instructions and survived the night, the monk told him that he no longer needed to fear his wife. Together they buried the demoness’s corpse and gave her a proper burial.

Not long afterward, Jiro Saburo cut off his topknot and became a disciple of Gen’ō.

Hime Oni

Tradition: Japanese Mythology
Alternative Names: Princess Demon
Category: Demon


The Myth

Hime Oni is the daughter of a demon who appears in the Kyōgen play Kubihiki (“Neck Pulling”). She is a young female demon who has never eaten a human before.

While Chinzei Hachirō Tametomo was passing through Inamino in Harima, a terrifying demon suddenly appeared and attacked him, intending to devour him. However, the demon decided that Tametomo would make a suitable first human meal for his daughter. He called his daughter and ordered her to eat him.

The demon princess approached Tametomo, but instead of attacking him, she was struck by his fan. Frightened by the blow, she cried out that it hurt and ran away. Her father became angry when he heard that Tametomo had struck his daughter and confronted him again.

Tametomo explained that he had only accidentally hit her while using his fan. He then proposed that he and the demon princess settle the matter with a contest. If she defeated him, he would allow himself to be eaten, but if he won, she would spare his life.

The first contest was arm wrestling. The princess reluctantly returned and, urged on by her father, accepted the challenge. However, she was far too weak to compete with Tametomo and was defeated almost immediately. She cried out in pain and ran away again, causing her father to become furious with Tametomo.

Tametomo then proposed a shin-pushing contest. Once again, the demon princess was easily defeated and burst into tears, while her father angrily confronted Tametomo.

Finally, Tametomo suggested a neck-pulling contest. In this game, a rope is placed around each person’s neck and the two opponents pull against each other. The princess agreed, and the contest began.

Her father acted as referee, but he became increasingly worried as Tametomo gained the advantage. He stopped the contest and declared that the difference in strength was too great. He then ordered his other demons to help his daughter.

The contest resumed with a large group of demons standing behind the princess. The father took the lead, and all of the demons pulled together on the rope.

Suddenly, Tametomo removed the rope from his own neck. The demons, still pulling with all their strength, were thrown backward by their own momentum and fell scattered across the ground. Tametomo used the confusion to escape, finally getting away from the demons.

Kowabakarachiki

Tradition: Japanese mythology
Alternative Names: Kowabakarachiki
Category: Demon


The Myth

Kowabakarachiki is a strange monster depicted stomping on a man. Its barking cry is described as “akirence,” while the man being stepped on cries out, “Oya wo ya, whatever.”

The creature appears in the Hyakki Yakō Monogatari, where it is listed as “Bamba Kowabakarachiki.” It does not appear in the Chinese texts associated with Heian and Han traditions, and the source describes it as a later local creation.

Kowabakarachiki was created as a wordplay based on the Yuri language, or Kaku language. Its name is said to play on a phrase meaning roughly “Koha — this is, well, stupid.” The strange cry of the monster and the words shouted by the man are constructed in the same playful manner.

The creature is therefore a yokai built around deliberately strange, foreign-sounding speech, turning unfamiliar language into a source of humor and supernatural absurdity.

Zheztyrnak

Tradition: Kazakh mythology
Alternative Names: Zheztyrnak, Jeztyrnak, Jez Tumshuk, Chulbus, Shulbus, Mu-shubun
Category: Demon


The Myth

Zheztyrnak is an evil demonic creature that usually appears as a beautiful young woman, although she can sometimes take the form of a terrible old woman. Beneath her attractive appearance she hides monstrous copper claws. Her ten fingers end in sharp, razor-like copper claws, while blue-tinted blades grow along her palms, each sharp enough to cut through stone. She usually hides these claws beneath long sleeves.

Zheztyrnak has tremendous supernatural power and possesses a loud, piercing voice. Her scream is deadly to birds and small animals. She is a frightening forest woman, especially dangerous to anyone who encounters her alone.

Zheztyrnak is sometimes compared to a vampire. She can hypnotize a person with her cold, unblinking gaze. Once her victim falls asleep, she attacks with her claws and sucks out all of their blood.

She is also fiercely vindictive. If a Zheztyrnak is killed, her husband seeks revenge for her death, and after his death, the victim may be pursued by their orphaned children.

One Kazakh tale tells of a hunter who encountered Zheztyrnak late in the evening. A young woman appeared at his hunting fire, and the hunter invited her to share his meal. He noticed that she constantly covered her nose with her sleeve, even while eating, and realized that she was no ordinary woman but a Zheztyrnak.

After she left, the hunter placed a log beside the fire and covered it with his clothes. He then climbed into a tree with his gun and waited. During the night, Zheztyrnak returned and threw herself onto the disguised log, believing the hunter was sleeping there. From his hiding place, the hunter fired and killed the demon with a well-aimed shot.

Alternative Names: Marawa, Myrlata, Myrlawa, Marava, Myrljata
Category: Demon


The Myth

Myrlyava is an evil demoness from Upper Sorbian folklore who appears as a repulsive, ugly, and perpetually dirty woman.

She was rarely seen, and nobody knew where she came from, where she lived, or what she fed on. Her mysterious nature made her a frightening figure in local folklore.

In Müllrose, in northern Upper Lusatia, people had a saying about a woman who had been working for a long time and was constantly busy with her work. They would say:

“She must be an old Myrlyava.”

The name was therefore used to describe a woman who was regarded as particularly unpleasant or unattractive.

Kulyashi

Tradition: Russian Mythology
Alternative Names: Kulyashi, Kuleshata, Kuleshi
Category: Demon


The Myth

Kulyashi are small water demons from the folklore of the Vologda region of Russia. They live in the water and are said to emerge during Epiphany.

People were afraid of accidentally scooping up a Kulyash when drawing water, and a saying recorded in Vladimir Dal’s dictionary warned that the Kulyashi came out of the water at Epiphany. Because of them, people were careful when going onto or drawing from the water during this time.

In the Russian North, these little water beings were also known as Kuleshi or Kuleshata. They appeared during Svyatki, the Christmas festive period, where they caused trouble and mischief for people. When the festive season came to an end, the creatures disappeared again.

Kulyashi were therefore imagined as small, troublesome supernatural beings that appeared for a short period, disturbed people, and then vanished. They were regarded as a kind of water-dwelling counterpart to the better-known Shulikuny.

Imp

Tradition: English Mythology
Alternative Names: Impe
Category: Demon


The Myth

Imps are small supernatural beings, usually described as lively, troublesome, and mischievous. They are often portrayed as lesser beings, sometimes resembling fairies and sometimes described as small demons or attendants of the Devil.

Imps are known for playing tricks on people. Their mischief can be harmless, but they can also mislead travelers, cause trouble, or otherwise disturb people. They were sometimes believed to seek friendship with humans, using jokes and pranks to gain their attention, although their behavior could just as easily drive people away.

In later folklore, imps became associated with witches and warlocks as familiar spirits. They were believed to serve their masters as companions, spies, or informants. Such familiars could take the form of animals such as black cats, lizards, or toads.

One of the best-known legends concerns the Lincoln Imp. According to a legend from Lincolnshire, the Devil came to Lincoln Cathedral accompanied by two imps. The imps began causing havoc inside the cathedral until an angel appeared and ordered them to stop.

One of the imps attempted to throw a stone at the angel. The angel commanded, “O impious imp, be ye turned to stone,” and the creature was immediately petrified. Its companion escaped, while the unfortunate imp remained as a stone figure inside the cathedral.
