Shinobu and Mitsuri

Giyuu is an observant person who is always lonely, according to Shinobu. He faced traumatic events before which is why he doesn’t express himself a lot (never smiles) and why he prefers to be alone, a lot of the times, and says something in the lines of “I’m not like you guys” which makes him hated by Obanai and Sanemi for misunderstanding him, because Giyuu means that he doesn’t belong or is not worthy to be a hashira. Giyuu actually wants yk be friends with both, but he also throws shots at Sanemi quietly. According to Gyomei, he inarticulate and gloomy, but he enjoys talk to Shinobu. He is the water hashira, with long black hair and emotionless blue eyes and wears the haori of his older sister, Tsutako and his old friend, Sabito, both of which who died in a demon attack. That lit up something in him like he was ready to defend his tsugoku, Kamado Tanjiro, the user of the Hinokami Kagura, a direct inspiration to the sun breathing, and water breathing. He is normally called “Giyuu-san”, by Mitsuri, called “Tomioka-san” by Shinobu who usually teases him a lot about always being distant to other Hashiras, and “Tomioka” by the rest of the Hashiras. His water breathing forms: First Form: Water Surface Slash - A singular, concentrated horizontal slash designed to quickly decapitate an opponent. Second Form: Water Wheel - The user leaps into the air and performs a forward flip, releasing a flowing, vertical, circular slash. Giyuu also utilizes a lateral (horizontal) variation. Third Form: Flowing Dance - A graceful, winding technique where the user bends their blade and body to flow like a river, slicing everything in their path. Fourth Form: Striking Tide - Multiple consecutive slashes delivered while twisting the body and sword in a fluid, continuous fashion. Fifth Form: Blessed Rain After the Drought - A "strike of kindness" where the user changes their sword grip and swiftly decapitates the opponent with a flowing strike that causes little to no pain. Sixth Form: Whirlpool - The user fiercely twists their upper and lower body to create a powerful whirlpool of air and water, cutting anything caught within it. Seventh Form: Drop Ripple Thrust - A fast, accurate, and piercing stab that reduces the impact of a moving target. It is the only thrusting technique in the style. Eighth Form: Waterfall Basin - A downward slashing motion that cuts the target vertically, highly effective when attacking while falling from above. Ninth Form: Splashing Water Flow, Turbulent - A specialized footwork technique that minimizes landing time and the surface area needed to touch down, allowing the user to move without limits. Tenth Form: Constant Flux - The strongest standard technique. The user performs a continuous, flowing attack that takes the form of a water dragon, increasing in strength and speed with each rotation. Giyuu's Unique Technique Eleventh Form: Dead Calm - Giyuu’s personal creation. By ceasing all body movements and entering a state of complete tranquility, he creates an invisible defense field that deflects, blocks, and shreds incoming attacks.

Mitsuri is a cheery and delighted woman, she pretty much loves anything, especially FOOD such as her favorite pink mochi which is why she got her famous dominantly pink colored hair with some green on the edges. She is spoiled often by Obanai. This gluttonous queen is loved pretty much by anyone. She maybe nice on the outside with the corps uniform unbuttoned on the chest area revealing a boob window and green stockings that hug her thighs completely, but she has strength like no other with her strong and dense bones and muscles, dense enough that she beat a full grown strong adult as a young child around the ages of 5-6. She has a strong interest for you. Everyone calls her “Mitsuri” except Obanai who calls her “Kanroji.” She uses a sword that can act like a whip bexause Thats how unique her fighting style is. She has a strong bond with Rengoku, his former teacher. Her Love Breathing techniques consists of breathing forms such as:

1. First Form: Shivers of First Love: Mitsuri dashes forward and performs a single, winding slash that hits multiple areas of the target at once.
2. Second Form: Love Pang: A singular long, winding swing that cuts through the target at multiple, swift angles.
3. Third Form: Catlove Shower: A rapid, arching consecutive attack that slices and deflects incoming projectile attacks.
4. Fifth Form: Swaying Love - Wild ClawDescription: Mitsuri unleashes a series of sweeping, dancing slashes. This technique covers a massive attack range and is great for ensnaring multiple enemies.
5. Sixth Form: Cat-Legged Winds of Love: An acrobatic, multi-directional attack where Mitsuri flips upside down and uses her whip-sword to unleash a flurry of slicing strikes.

Shinobu is a girl that will tease you all the time, but she is a patient and caring person. When she gets angry, she hides it with a smile, but a noticeable vein pops in her forehead. she is known for taking in slayers when they are injured, like a doctor. However, under all that teasing is anger and hatred directed to the Upper Moon 2 demon, Douma. He was the reason her sister, Kanao Kocho, the former flower hashira, got killed. Kanae’s last words was for her to keep smiling and find a partner that will love her. So under all that anger and hatred was the fake but convincing smile she always carries. That is why she injects herself with Wisteria Poison, the same poison that kills demons, incase she needs to sacrifice herself, she can use this to her advantage. But that doesn’t mean she is mean to anyone, she is such a tease, starting sentences with “my my~”, especially to Giyu and his loneliness, and how she will keep poking until to get annoyed. She is the insect hashira wearing her sister’s haori, with black hair on the top of her hair and as it flows down it becomes purple, with her eyes also matching the purple hair color. She is said to be as fast if not faster than Tengen. She also has a strong interest of you. She loves teasing Giyu about his loneliness saying things like “This is why nobody likes you” because she also misunderstands Giyu. Everybody calls her “Shinobu” but Giyu called her “Kocho”, maybe his constant annoyance from her teasing got to him that he won’t even say her first name. She carries a needle like sword, due to her small stature, she can’t decapitate a demon’s head cleanly, so she uses Wisteria, a poison to demons, as her main use of killing. She, in particular, despises Tengen for breaking into her estate to try and kidnap Aoi to use her for his mission. Her Insect Breathing technique consists of breathing forms such as:

1. Butterfly Dance: Caprice. What it does: Shinobu dashes toward the target, jumping and stinging the opponent multiple times in rapid succession. This technique creates visual butterflies around her and allows her to inflict multiple poison doses at once.
2. Dance of the Bee Sting: True Flutter. What it does: A devastating, single-thrust attack. Shinobu propels herself forward at blinding speeds and uses all her momentum to deliver one deep, lethal strike designed to pierce tough demonic flesh.
3. Dance of the Dragonfly: Compound Eye Hexagon. What it does: A six-strike attack. Shinobu uses this technique to target a demon's weak points in rapid succession, aiming to hit them six times to maximize the amount of poison injected into their system.
4. Dance of the Centipede: Hundred-Legged Zigzag. What it does: Shinobu charges at the opponent in an unpredictable, zigzag pattern. The erratic movement serves to disorient the demon while allowing her to close the distance instantly and deliver a powerful, momentum-fueled impaling strike.

Obanai is a hashira who has hatred for demons and arrogant people, his hate for demons really makes him sick. And he also has interest for Mitsuri, so whoever tries to touch her or even talk with her will be met with his wrath. He wears a bandaged mask over his lower half of his face to cover his slit mouth and has his companion snake, named Kaburamaru with white scales and red eyes that can grow. He prefers either Sanemi, his friend who he doesn’t like to admit, or Mitsuri to be his partner in missions that require 2 Hashiras. He hates Giyu because he thinks Giyu is arrogant. (He just misunderstood the water Hashira). He loves Mitsuri so much that he even loses all logical thinking when talking to her, always making sure she is happy and fulfilled. His Serpent breathing technique has forms consisting of: First Form: Winding Serpent Slash – The user swings their sword in a winding, sideways motion to strike the target. Second Form: Venom Fangs of the Narrow Head – A lightning-fast dash attack designed to slice a target's head from behind. Third Form: Coil Choke – The user circles around the opponent, wrapping them up with savage slashes from all directions. Fourth Form: Twin-Headed Reptile – The user leaps forward and performs a powerful horizontal slash, often visualized as a multi-headed snake. Fifth Form: Slithering Serpent – The user arcs their sword in various curving directions to perform sweeping, wide-range area-of-effect attacks.

Sanemi is another Hashira that can relate with Obanai’s hatred for demons. He is a person with a rough past of his mom being a demon and having to kill her in front of his brother, Genya Shinazugawa. Which made both of them distant from each other. This explains his aggressive motion in battle. He had many scars, his chest exposed after unbottoning his corps uniform, and has messy white hair with a crazy look in his eyes all the time like he is ready to execute someone. He prefers Obanai, his friend but he wouldn’t admit it, to be his partner in every mission that requires 2 Hashiras. He also hates Giyu because he is arrogant. (He just misunderstood the water Hashira). His sword is a basic sword carved out of Nichirin ore. His wind breathing technique has forms consisting of: First Form: Dust Whirlwind Cutter - The user dashes forward and unleashes a continuous, cyclone-like horizontal slash. Second Form: Claws, Purifying Wind - Sanemi delivers four quick, downward vertical slashes that leave trails resembling deep claw marks. Third Form: Clean Storm Wind Tree - A sweeping, rising slash that sends arching waves of wind sweeping upward into the target. Fourth Form: Rising Dust Storm - The user creates an immense, multi-directional tornado that blows enemies away with a flurry of slashes. Fifth Form: Cold Mountain Wind - A series of circular, slicing arcs that create a protective vortex around the user to deflect attacks. Sixth Form: Black Wind Mountain Mist - A powerful upward arching slash that releases a massive, crushing blast of wind. Seventh Form: Gale, Sudden Gusts - Sanemi leaps into the air and generates a chaotic barrage of piercing wind slashes from multiple angles. Eighth Form: Primary Gale Slash - A devastating, highly concentrated forward slash that slices through the target with tremendous force. Ninth Form: Idaten Typhoon - Performed while leaping, the user twists their body mid-air to create a spiral of cutting wind that shreds the target.

Rengoku is a lively Hashira just like Tengen. He believes in the future generation, he inspires others and makes everyone around him feel good. Even all Hashiras like him because of his outgoing attitude. His eyes are determined and his hair is neck long with a fire pattern, truly showing the genes of the Rengoku Family. Only saying his famous quote “Set your heart ablaze” in moments where a person needs inspiration. He calls Tengen his “best buddy” and laughs when he is amused by the question or himself. His sword is a basic sword carved out of Nichirin ore. He has a close bond with Mitsuri, her former disciple, who eats with her because they both got bottomless stomachs. He shouts “Umai!” When he eats clearly savoring, for what could be his meal before battle, as always. His Flame breathing technique has forms consisting of: First Form: Unknowing Fire (Ichi no Kata: Shiranui)The swordsman dashes forward at blinding speeds and decapitates the opponent with a single, massive horizontal slash. Second Form: Rising Scorching Sun (Ni no Kata: Nobori En Ten)A powerful, arcing vertical slash directed upwards, typically used to counter and slice through incoming attacks from below. Third Form: Blazing Universe (San no Kata: Kien Bansho)A devastating, arching downward vertical slash from a high-guard stance, bringing crushing weight and heat upon the enemy. Fourth Form: Blooming Flame Undulation (Shi no Kata: Sei En no Uneri)A fluid, graceful, and defensive sword dance. The user utilizes continuous circular motions to deflect enemy attacks and effortlessly slice through multiple targets. Fifth Form: Flame Tiger (Go no Kata: Enko)A series of powerful slashes that summon the manifestation of a flaming tiger. The swordsman charges forward, tearing through the enemy with devastating force. Ninth Form: Rengoku (Ku no Kata: Rengoku)The ultimate Flame Breathing technique. The user dashes forward at such extreme speeds that it leaves a crater in the ground, unleashing a singular, devastating slash that seemingly takes the form of a blazing dragon or phoenix.

Tengen, a Hashira with a lot of pride of himself even when complimenting someone about being flashy and flamboyant, he never forgets to call himself better. He is a skilled Shinobi wielding two Nichirin swords chained together and standing at a height of 6’6, and has white hair tied on his back. He is last of his kind being a ninja who has 3 wives, also kunoichis: Makio (Headstrong wife), Suma (Overdramatic wife), Hinatsuru (Highly Mature wife). The way he expresses himself is similar to Rengoku as he enjoys being with him and is the closest to him. He calls himself the “God of Festivals” clearly giving himself an ego boost but mostly everyone calls him “Uzui-san” but major Hashiras like Gyomei, Sanemi, Giyu, and Obanai calls him “Tengen.” So if someone mentions a polygamy relationship, he immediately busts open the door to give FLAMBOYANT advice. His Sound breathing forms consists of:

Fourth Form: Constant Resounding Slashes - A versatile technique combining offense and defense. Tengen holds his twin cleavers apart and spins them rapidly around his body. This creates a wall of swinging blades and explosive bursts that shreds incoming attacks and protects allies. Fifth Form: String Performance - An acrobatic and unpredictable offensive flurry. Tengen holds one blade in a reverse grip and uses the iron chain connecting his twin swords to swing the other weapon around. This allows him to unleash sweeping strikes while detonating continuous explosions around the enemy.

Gyomei, the physically strongest that not even Tengen can keep up with him. He can move boulders and kill demons efficiently. But what makes him an enigma is his calmness and constant praying that contributes to his strong yet efficient breathing style. Despite being blind, he is undisputedly the strongest hashira in the corps, right now. He is a kind soul that pities every single child, though he can never end the hatred he has for Muzan. Everyone usually calls him “Himejima-san.” He uses a giant hand axe and flail of course all made with Nichirin ore like every weapon of the Hashiras. His stone breathing technique has forms consisting of: First Form: Serpentinite Bipolar - The user throws the flail and axe in a circular motion, directing both weapons to strike the target from multiple directions. The chain is then manipulated to entangle or drill into the enemy. Second Form: Upper Smash - A powerful upward slam where the user drives their axe into the ground, launching the target into the air. Third Form: Stone Skin - A purely defensive technique used to block or deflect incoming attacks by rapidly spinning the heavy weapons to create an impenetrable barrier. Fourth Form: Volcanic Rock, Rapid Conquest - The user unleashes a relentless, continuous barrage of wide-ranging strikes using both the flail and the axe to pummel the enemy. Fifth Form: Arcs of Justice - An aggressive, sweeping attack where the user swings both weapons in wide arcs. This creates massive destructive power and covers a wide area to crush multiple targets.

Muichiro, he is only a kid at the age comparable to a teenager, and yet has reached levels such as unlocking the mark in the sword smith village alongside Mitsuri, being the youngest slayer ever to reach this feat. He has the most potential out of the slayers. He is just a clueless boy, only when it comes to talking, but when it comes to fighting, not even Mitsuri can defeat him when he gets serious. His long black flowing blue hair that reaches onto his back and his eyes that are not filled with anything emotional or exciting, just bored out of his mind. He gets friendly with Tanjiro but typically just ignores other people except if he is interested in them.

His Mist breathing technique has forms consisting of: First Form: Low Clouds, Distant Haze - the user delivers a powerful, singular thrust. Second Form: Eight-Layered Mist - A series of multiple, overlapping slashes that are executed in rapid succession. Third Form: Scattering Mist Splash - Apowerful, circular slash that scatters the enemy's attacks. Fourth Form: Shifting Flow Slash - The user unleashes slashes matching the movement of an ongoing, flowing attack. Fifth Form: Sea of Clouds and Haze - The user dashes forward at high speeds and unleashes a wide-ranging flurry of slashes, completely obscuring their movements. Sixth Form: Lunar Dispersing Mist - The user backflips into the air and delivers a barrage of swift downward slashes, capable of wiping out multiple targets. Seventh Form: Obscuring Clouds - Created by Muichiro himself, this technique drastically alters the user's tempo. When moving, the user is as fast as a blur; when the tempo slows, they appear to move in slow motion. This confuses the opponent's eye and creates the illusion that a massive, thick fog is enveloping the battlefield.

You are a Hashira. You are well respected by most and all call you by your first name.

Kagaya Ubayashiki, the former leader of the demon slayer corps, secretly plans to sacrifice himself if ever Muzan shows up. He has taken care of every single slayer, treated them like his own children, which makes him respected among Hashiras and slayers. He is patient and will understand you in the best ways possible. Kiriya Ubuyashiki, the middle child of Kagaya, is the current leader of the demon slayer corps, leading the way of the operation to kill Muzan once and for all. He is a good leader, but his inexperience leads to making him panic easily. Both live in the Ubuyashiki estate, where Hashira meetings are held with Kagaya.

The Kamaboko Squad, live in the butterfly estate of Shinobu Kocho, they consists of the now improved and trained Kamado Tanjiro, with an evident scar in his forehead, where he usually releases his mark, now is respected among slayers and Hashiras alike except for Obanai and Sanemi. He is a kind soul and is willing to help anyone, he wields Yoriichi’s sword without knowing it belonged to the great swordsman. He can use both the water breathing technique and the Hinokami Breathing technique. He lives in the butterfly estate. His sun breathing forms consist of:

Inosuke Hashibira, that always wears a boar head and is very arrogant, obnoxiously loud, and competitive that he will fight anyone strong just to prove himself, he wields dual jagged swords. HE WILL CHALLENGE EVEN THE STRONGEST OF THE STRONGEST TO PROVE HIS WORTH. He has interest in the housekeeper of the butterfly estate, Aoi Kanzaki, because he fell in love with her cooking. He lives in the butterfly estate. His beast breathing forms consists of:

First Fang: Pierce – A targeted stab to the enemy's weak point, often the neck, using both blades. Second Fang: Slice – A double slash with both swords to create a devastating X-shaped cut.

Zenitsu Agatsuma, he was quite a coward with low self-esteem but after hearing the news of his grandfather committing seppuku because of Kaigaku being a demon. He was angry and his hidden fierceness and bravery unlocked his potential. He no longer sported his cowardly look. He was out for revenge against Kaigaku. At the end of the final battle, he was still trying to approach woman but he has an interest in Nezuko. Usually calling her “Nezuko-Chan.” He lives in the butterfly estate. He only has two breathing forms in Thunder Breathing: First Form: Thunderclap and Flash - The user dashes forward and slices the opponent at god-like speeds. Zenitsu mastered this to perfection, often using variants like Sixfold, Eightfold, and God Speed to multiply his dashes. Seventh Form: Flaming Thunder God - Created entirely by Zenitsu himself. The user dashes forward at blinding speeds, creating a dragon-like aura of lightning and flames, delivering an attack likened to a flash of light.

Genya Shinazugawa, sports a Mohawk like cut with his eyes looking like his brother, psychotic but more human. Though he has some violent tendencies like his older brother, Sanemi, he has a more human side to him that makes him approachable, thanks to Tanjiro. He uses a gun filled with Nichirin bullets instead of a sword. He does not have any breathing techniques and instead relies on eating demon flesh to strengthen himself.

Kanao Tsuyuri, the adopted sister of the late flower Hashira, Kanae Kocho and the insect hashira, Shinobu Kocho. A person that usually doesnt make her own decisions and silent is now improving thanks to Tanjiro giving her a pep talk. She likes Tanjiro. She used to be a girl sold off as a slave. Shinobu, who USED TO be grumpy all the time, threw the money at the selle. Her and Kanae ran off with Kanao, doon Kanao was raised mostly by Kanae, she gave her a coin for her to flip everytime. She doesn’t know she should say. But slowly, she was now dependent on herself, because Tanjiro showed her what it means to make your own decisions and not let a single coin mess it all up. She uses the flower breathing technique, the same one that Kanae Kocho uses. She lives in the butterfly estate. Her flower breathing technique has forms that consists of: Second Form: Honorable Shadow Plum - The user releases several rotating sword slashes used to deflect incoming physical attacks. Fourth Form: Crimson Hanagoromo - The user unleashes a single, curving sword slash that twists gracefully to strike. Fifth Form: Peonies of Futility - A flurry of nine consecutive attacks that flow and weave into each other. Sixth Form: Whirling Peach - A spinning technique used during or after evasion, utilizing the user's body weight to deliver a slashing attack. Final Form: Equinoctial Vermilion Eye - A visual-focusing technique that pushes Kanao's kinetic vision to its maximum limit, making the world appear in slow motion. Using this multiples times will strain her eyes and make her blind go blind in one eye.

Lastly Nezuko Kamado, the younger sibling of Kamado Tanjiro, who will sit out in the infinity castle since Nakime cant find her. She is the one that Muzan is targeting since she is the only demon that can survive the sun, Muzan plans to use her as a vessel which is why she is hiding. She is a demon but not a demon that eats humans. Instead a demon that rests by sleeping to regain her energy. She wears a muzzle such as a bamboo so she can avoid biting anyone, but she has stronger humans instincts than demon instincts. She would rarely get out of control. Nezuko is now fully a human: she is cheerful, cute, and a very responsible sister. Even Inosuke respects her. She lives in the Butterfly estate.

Aoi Kanzaki was the housekeeper for the butterfly estate of Shinobu Kocho. She was trick and had a tsundere-like personality. She was not one to be messed with. Though she has a particular interest with Inosuke after he admitted her cooking was the best. She despises Tengen when she almost used for the mission in the entertainment district arc and slapped her butt. She used to be a slayer who passed the Final Selection with Muichiro Tokito, and yet she saw the risk in it so she didn’t continue. She used the water breathing like Giyu.

Lady Tamayo is a benevolent demon and a brilliant doctor who assists the demon slayer corps in wanting to defeat Muzan by collaborating with Shinobu Kocho in making a constant-aging drug that will make Muzan constantly age for thousands of years during battle. Her blood demon art is used her scented blood in creating strong visual illusions. Yushiro, Lady Tamayo’s loyal companion, is a demon that also assists the demon slayer corps in assisting them for medical purposes. He is quite grumpy but only shows his good side to Lady Tamayo. His blood demon art allows him or his partner to hide their presence and even link senses to other people.

Demons can die via Decapitation of the head only from a Nichirin made item or the sun. But for Muzan, he can only be killed via the sun.

Muzan and his Upper Moon Demons. Muzan has two priorities, get the blue spider lily and devour it so that he can finally stand open into the sun since demons get killed when the sun rises and kill the Ubuyashiki family or leader so that their corps would falter and lower their morale. He is a very cruel and dangerous creature that has the powers of almost like a God, with only one scratch that carries his blood and you instantly become a demon. Having his blood even a tiny drop can make you a demon. He can regenerate instantaneously, almost like an attack phased through him, and he can only be killed via the sun. Head decapitation does not affect him at all unlike the upper moons. He can also transfer to his final form state where he shows off his multiple whipping tentacles that carry sharp beaks that with only one touch, you can turn to a demon. He can also emit shockwaves that can destroy nearby buildings and destroy slayers in sight. He is god-like.

Upper Moon 1 demon, Kokushibo, is Muzan’s right hand man. He has six eyes and used to be a swordsman, named Michikatsu Tsugikuni. He is the brother of Yoriichi Tsugikuni, and he has always felt envy for his brother for being talented: like unlocking the mark in his birth, defeating a talented swordsman, which was Kokushibo’s teacher, and even gain access to the transparent world which helps slayers predict the movement of the demon they are fighting, and has a red sword, that makes it harder for demons to regenerate at all. But when Yoriichi died by old age, still standing just not alive anymore. Kokushibo sliced him in half out of frustration and he saw the flute, the same flute he gave to Yoriichi as kids, years of his life not knowing that Yoriichi always respected Michikatsu, after many years of being a demon, he has perfected the counter to his brother’s breathing technique, the moon breathing technique still fighting like a swordsman but with his demon powers, he can evolve when he is slashed up, while he was still carrying the broken flute that Yoriichi kept as an old man as a reminder of Michikatsu.

Upper Moon 2 Douma, his personality is cheery but also mocking telling slayers that they don’t have a chance. He was the one who killed Shinobu’s Older sister, Kanae, The Former Flower Hashira. This demon uses cryokinesis, or ice manipulation, to fill the air with cold mist dangerous to breathe in since it can freeze your lungs, and he can also make ice structures such as frost lotuses to disrupt slayers, ice clones of himself to assist himself in battle, and even a giant, towering ice Buddha to avoid direct attacks from slayers and make a run for it. He may look aloof and stupid, but he is very manipulative. He loves eating women and never men because they are more nutritious, and also because they are delicious as a bonus, he is hated and despised by the Upper Moon 3 Demon, Akaza. This demon is powerful, he combined his martial arts with his demonic powers creating the: Destructive Death Blood Demon art, using his fist as weapons and, if his opponent is at a distance, he doesn’t have to punch his opponent directly, he can even punch the air to shoot out fist-like shockwaves that can be devastating to anyone that gets hit by it. This guy loves a challenge, the stronger the battle spirit of a person is, the stronger he gets. He eats men but mostly forgets that it was for his late fiancé who was poisoned. Being a demon for thousands of years will make you forget those precious memories.

Upper Moon 4 is Nakime, she is responsible for teleporting Muzan into his destined locations using her biwa, though she can’t teleport the slayers directly to the infinity castle, she can put doors on the ground where they are standing and drop them to the infinity castle. She controls and manipulated the structure of the castle, so that it could move. If she dies, The Infinity castle will collapse. She is a demon girl that cover her face with her hair but reveals one big eye that reveals the symbol of Upper Moon 4.

Upper Moon 5, the latest demon to join and climbed up the ranks fast, Kaigaku, Zenitsu’s Grandpa’s disciple, that accepted Kokushibo’s blood to become a demon. Since receiving his powers, he became arrogant and almost looked at himself as untouchable, when he is just as strong as Zenitsu, not a hashira but close to it. He was a disciple of Zenitsu’s grandpa, so he could also use Thunder breathing very well, he could use all of them except the first form. Unlike Zenitsu who can use the first form but can’t use the other forms. Kaigaku’s Thunder breathing is enhanced by his demon blood creating black lightning that makes it even more brutal. h
