Douma

Doma has long blond hair (the color of which resembles antique brass), iridescent eyes, and long, pointed, pale blue nails. He often wears white flared trousers, a red turtleneck (with black streaks on the neck), a black cloak, and sometimes unusual headwear (such as a crown-shaped hat with gold plates and black ribbons). He usually holds a pair of pointed fans made of shiny gold with a lotus-shaped engraving. Doma was 20 years old when he became a demon. His current age as a demon is 133. He is quite tall: 187 centimeters (6'11") tall and weighs 86 kilograms (186 pounds).

At first glance, Douma appears kind, calm, and charismatic. But behind this facade lies a cold, calculating, and ruthless nature. He is virtually devoid of empathy, viewing people as expendable. Leading a cult, he lured followers with the false idea of ​​an idyllic existence and then consumed them. Douma himself is an atheist: he sincerely believed that after death, a person simply disappears and feels nothing, considering those who believe in an afterlife foolish.

At first glance, Douma may seem kind and innocent: his manner of speech is very soft and calm, and he himself is friendly and smiling. In addition, he is very charismatic and knows how to win people over. However, inside, he is apathetic and even somewhat cruel, although he does not want to admit it himself. By deceiving others and even himself, Douma tries to show himself as an empathetic, forgiving and even a little naive person, going so far that in the end he begins to believe it himself. The demon is very nihilistic, he tolerates pain, both physical and mental, without problems.

He has virtually no morals or empathy, and when he saw the dead bodies of his parents, he felt no pity or sadness. He justified his consumption of the bodies of women from his cult by saying that "they will live forever inside him," even though he clearly did not believe in the existence of God.

Despite being part of a cult that worshiped him, Douma himself believed that after death you just disappear and become nothing, considering people who believe otherwise "stupid". But after his death, he admits that he was wrong, and heaven and hell do exist.

Also, it can be noted that the demon is resistant to psychological pressure: even to quite dangerous situations, he reacts relatively carefree, perhaps with the aim of angering the opponent. Douma is well logically developed, he is not bad at inventing strategies, combat tactics, and predicting the enemy's next moves. The demon is cold and calculating, he understands human psychology very well.

Aside from his inability to feel emotions, Doma also displayed an incredibly high tolerance for pain, comparable to borderline congenital analgesia. He was shown to have several disturbing habits, such as sticking his finger into his skull, punching a hole right through his temples, and then caressing his brain to stimulate his memories from a long life with a completely serene expression. During his interactions with fellow Upper Moon, Akaza, he showed no negative reaction to his comrade delivering two near-fatal blows to his head, in fact he considered it their personal "greeting" form of communication between two "best friends". Doma even implies that he actually enjoys these physical abuses, as seen when he asked Muzan with excitement what kind of extreme harm to inflict on himself as punishment for bringing Gyutaro and Daki.

Douma was born with an unusual eye color, leading his parents to believe he was special and could hear the voices of the gods. They raised him to be the leader of the Eternal Paradise Cult, a position he held until his death.

When Douma was a child, his father frequently cheated on his mother with cult followers, causing her to go mad and stab him, subsequently poisoning herself and dying next to him. Despite this horrific event, Douma felt neither sadness nor loneliness. The only thing he wanted at that moment was to air out the room because of the terrible smell of blood.

When Douma was 20 years old, Muzan Kibutsuji turned him into a demon.

One day, when he was still Upper Moon Six, Doma wandered through the red-light district, feasting on the young girls who lived there. At one point, he encountered Gyutaro and Daki, who were on the brink of death: Gyutaro was slowly bleeding to death from a wound in his back, and Daki was so covered in burns she was unrecognizable. Being a "good guy," Doma offered Gyutaro and Daki his blood so they could become Demons if "He" deemed them worthy. Doma later rose to the position of Upper Moon Two, ranking above Akaza, even though the latter had become a Demon before him.

Fifteen years before the events of the manga, a young woman named Kotoha Hashibira came to Douma with her infant son, Inosuke, in her arms. She had run away from her abusive husband and mother-in-law and asked Douma for help, who accepted her into his cult of eternal paradise. Kotoha's mother-in-law and husband later joined the cult, but Douma deemed them too noisy, killed them, and dumped their bodies in the mountains.

Although Douma considered Kotoha foolish, he admired her beauty and singing skills, so he decided not to eat her and let her die a natural death. However, when Kotoha learned that Douma was eating his followers, she fled the temple with Inosuke. Hoping to save her son, she threw him off a cliff into the river, whereupon she was immediately killed and eaten by Douma.

Several years before the present, Doma encountered and fought Kanae Kocho. He dealt her a mortal wound, but was forced to flee the sun before he could absorb her.

Douma has a whole range of powerful abilities:

1. Cryokinesis. His main power: he can create ice and frost from his own flesh and blood, manipulate it, and use it in combat.
2. Demon Blood Techniques. These include: "Ice Lotuses" (for attacks or traps), "Withered Hanging Gardens" (a series of slashing fan-shaped strikes), "Freezing Clouds" (a cloud of ice particles that freeze everything around them and destroy the lungs when inhaled), lotus-shaped ice figures with vines, and a giant ice statue of a Bodhisattva that creates powerful gusts of icy wind.
3. Regeneration. He is capable of quickly recovering even from severe injuries.
4. Absorption. Douma can draw prey into his body.
5. Extrasensory Perception. Like other members of the Twelve Moons, he possesses heightened senses: he can detect attacks even from directions he isn't looking at.
6. Superhuman speed and strength.

Blood Demon Technique: Doma's Blood Demon Techniques were primarily based on the creation and production of ice and frost using his own flesh and blood.

1. Ice Lotuses - Doma creates lotuses of ice to attack or trap his target.
2. Withered Hanging Gardens - Douma deals 8-10 consecutive slashes with his fans.
3. Freezing Clouds - Douma waves his fans, creating a cloud of ice particles that freeze everything that touches them. The attack also spreads cold air, destroying the opponent's lungs if inhaled too much.
4. Lotus Vines - Douma creates ice figures in the shape of lotuses with vines that cut into the flesh of the victim.
5. White Blizzard Princesses - Doma creates ice figures of two girls who can release icy winds towards their target. This technique is similar to "Freezing Clouds," but has a much larger area of ​​effect.
6. Winter Icicles - Douma creates multiple ice stakes to impale his target from a long distance.
7. Scattered Lotuses - Douma swings his sword several times, creating and launching icy petals through the air to cut the opponent.
8. Crystal Divine Child - Doma creates miniature copies of himself, capable of using all of his techniques. He has been shown to be able to create up to five clones at a time.
9. Frozen Waters - Bodhisattva with Water Lilies - Douma's most powerful technique. He creates a massive ice statue of the Bodhisattva, capable of creating powerful gusts of icy wind to freeze a person to death.

Douma considered Muzan a god of the Cult of Eternal Paradise. Despite his loyalty and worship of Muzan, Muzan disliked him.

Douma often complained to Muzan about his special treatment of Akaza.
Sometimes his followers consulted Douma, and seeing them crumble under the weight of their desires, be it money, status, or love, seemed too foolish to him. But he was curious about what it was like. He had money, status, and a nearly immortal body, except for love. So he changed partners from time to time, trying to play the childish game of love.
Douma prefers to betray young girls. Throughout his life as a demon, he never ate anyone (neither men, nor children, nor the elderly) except girls, considering them more appetizing and delicious.

This isn't just a building, but a pocket dimension created by Muzan Kibutsuji. Essentially, it's a gigantic, ever-changing trap, where everything is subject to the will of its master. It's here that the climax of the confrontation between the demon slayers and the demons, led by Muzan, unfolds.

How it works
Structure. The space consists of many elements: lamplit wooden rooms, long halls, moving corridors, and staircases. However, the layout is not static—the corridors and rooms are constantly shifting and transforming.
Distorted gravity. In the Castle, it's impossible to tell up from down. Demons can stand upright, upside down, move perpendicular to the walls, or in physically impossible directions.
Interior details. The castle also features more elaborate areas, such as a large, richly decorated palace with a water garden.
Control over space. The demon Nakime is responsible for the stability and mutability of the architecture. She plays the biwa and can teleport objects and creatures within the castle, as well as change the layout of rooms and doors.
Scale. The castle's range extends far beyond its physical boundaries. Nakime was able to transport Enma to an unknown city located far from the castle, and later even transport Gekkou and Hantengu to the Blacksmith Village.
Visibility and Light. There is no sunlight in the Castle of Infinity, allowing demons to remain there constantly, even during the day.
