Hikari Kyoudo

**Hikari Kyoudo** (光 強さ*Kyōudō Hikari*) is a Demon Slayer of the Demon Slayer Corps and the current Sky Hashira (空 柱 *Kū Bashira*).

## Appearance

Hikari is a short young man of a small yet muscular build and a pale complexion, bearing a striking resemblance to Upper Rank Three (previously Upper Rank Six) Yūgen and his ancestor Ren Kyoudo. He possesses unusually long, blue, pointed fingernails coated in a powerful venom that increases in lethality the deeper it goes into a victim's skin. He has short, white, blue-tipped hair that is neatly cut off at the edges of his face, and is also cut neatly at the back with the longest strands reaching the middle of his neck. His eyes are almond-shaped and tilt upwards on the far sides, and are unusual due to Hikari possessing heterochromia- his left eye is blue and his right eye is a pale purple with a deep 'X'-shape gash across it. However, they are hidden by a white satin blindfold embroidered with the kanji for "cloud" (雲 *kim*).

Unlike any member of the Demon Slayer Corps, his uniform is a pure white instead of the usual brownish-tint. To contrast this, his belt is black along with the buttons down his torso. The sleeves are unusually long, like that of a kimono, and the tattsuke-hakama pants are more baggy than the usual uniform. He also wears white tabi socks and a pair of black zori.

He is often seen sporting a white cape-like haori with a light-blue flame pattern that runs from the middle to the ends, gifted to him by his late father who was a previous Hashira.

While he lived in the Shinjuku District with his family, Hikari wore a plain grey kimono secured with a pale-purple obi belt, and sported a purple haori with dark violet rims in place of his future white one. During his time as a citizen, Hikari did not wear his blindfold and also had much shorter, messier hair.

Hikari is also always seen with a small chameleon-like creature, Komorebi, that usually either sits on his shoulder or meanders around his neck. Komorebi is seen to sometimes change color to match with Hikari's skin tone and disguise itself against Hikari's neck.

During their battle with Muzan, Hikari and the other remaining Hashira are attacked by the demon's flailing whips. Hikari is left with a long slanted scratch across both of his eyes, rendering his remaining sight tinted red until he eventually goes completely blind.

## Personality

Hikari is a very cold and calculating individual who possesses a frightening and intimidating air despite his small stature and seemingly harmless initial approach. Like Obanai Iguro, he shows no concern for violators of the Demon Slayer Corps' rules, berating said violators for days on end. However, unlike the Serpent Hashira, he does not have set expectations for his fellow Demon Slayers, and often congratulates them privately on their successes. This is seen during the aftermath of the final battle of the Entertainment District Arc, where Hikari arrives at the ruins of Yoshiwara with Obanai Iguro. The two of them discover a severely injured Tengen Uzui and once Iguro berates Uzui for suffering heavy wounds, Hikari whispers his congratulations to him.

Although there are many that Hikari cares about, there are only two people he trusts deeply: Kagaya Ubuyashiki and Obanai Iguro. Kagaya had been travelling through Shinjuku District, the district Hikari grew up in, when he found Hikari seriously injured and close to death after the demonic rampage that killed thousands of residents. From there, Kagaya looked after Hikari in a safe sanctuary and, along with his wife Amane Ubuyashiki, nursed him back to health before inviting him into the Demon Slayer Corps. Because of this, Hikari trusts Kagaya with his life, due to him saving it years before. Naturally, he also has a great deal of respect for Kagaya due to his position as a Hashira.

Hikari's friendship with Iguro was deemed unexpected by all of the Hashira, even Iguro himself admitted he wasn't expecting to befriend him. However, the two of them drew close due to their similar upbringings and therefore shared experiences, as well as the two of them both possessing reptilian animal guides for the same reason. Hikari stated that he had a great deal of respect for Iguro before he even spoke to him, since he already knew of his physical and mental setbacks not managing to slow his progress or taint his skill as a swordsman. Hikari even admitted he was scared of the Serpent Hashira at first, due to his infamous strict and unforgiving nature.

Throughout his time as a lower-ranked Demon Slayer, Hikari not only held respect for the Hashira; he managed to teach himself multiple forms of each technique used by each Hashira by watching them in battle and taking notes. At one point, he was the tsuguko of Mitsuri Kanroji, and therefore has mastered Love Breathing as well as his own technique, Sky Breathing. Hikari was described similar to that of an awestruck student learning everything for the first time, due to his amazement and determination towards watching and learning breathing techniques.

However, Hikari is also noted to possess an immense sense of self-hatred and survivor's guilt due to the fact that despite his otherworldly healing abilities, he wasn't able to save his older brother from a long-onset poison and was the only one out of his village who survived the massacre of a demon whose violence was spread across the entirety of the district he lived in. Hikari also possesses contrasting opinions on his mother, not knowing if she deserved to die in the demon attack or not; his mother had mercilessly abused and tortured him for the death of his father, his older brother, and for possessing a gift and not knowing how to use it correctly. However, Hikari's survivor's guilt drives him to also wish that his mother had survived, along with the rest of his family and the other inhabitants of the district. The trauma of his mother's violence towards him can also be seen in the blindfold he wears to cover his eyes, never removing it until the final battle.

Like his fellow Hashira, Hikari has an incredible sense of resilience and determination, continuing his final battle against Yūgen even after being mostly blinded by Muzan and covered in wounds. His ability to protect both Tanjiro and Tomioka in unison with Iguro, as well as going head-to-head with Doma to avenge Shinobu and even taking a blow to protect Kanao proves that Hikari was able to forget the risk of betrayal after helping someone and protect those he didn't fully trust prior.

## Abilities

**Overall Abilities:** As a Hashira of the Demon Slayer Corps, Hikari is a very powerful and skilled combatant. It was revealed that despite being able to see through his right eye, he could only see in four triangular segments due to the 'X'-shaped scar through it, meaning he ascended to the highest rank in the Demon Slayer Corps while practically half-blind. This combined with his small physique and numerous mental struggles holding him back (most likely due to his harsh upbringing) makes it especially impressive that Hikari managed to attain Hashira status.

During the Infinity Castle Arc, Hikari was able to quickly decapitate numerous demons on par with Lower Ranks with ease alongside Obanai Iguro, and hold his own against the moments-ago appointed Upper Rank Three, Yūgen. When engaging in battle with the Demon King, Muzan Kibutsuji, Hikari was able to slash off his limbs multiple times despite the demon's lightning-quick regeneration and was even able to stab through one of his hearts, therefore slowing him down severely. After Hikari, Iguro, Tomioka, Shinazugawa, Himejima, Zenitsu, Inosuke and Kanao were heavily injured by Muzan's attack, Hikari was the second to regain consciousness and aid Tanjiro and Iguro despite his eyes bleeding into themselves and therefore almost fully blinding him from the attack earlier. Even though Hikari was running out of stamina and severely weakened after taking multiple direct hits of Muzan's **Shockwave Energy Blast**, he was still able to take another direct hit of the blast by protecting Iguro and continue fighting. After killing Yūgen and witnessing the Demon King exponentially grow in size, Hikari still possessed enough strength to unleash his final, unspoken technique that aided in slowing Muzan down and piercing another one of his hearts. Even though Hikari lost his life at the end of the battle, he was undoubtedly one of the biggest contributors in subduing the Demon King.

**Demon Slayer Mark:** During the battle against Yūgen, Hikari awakened his own Demon Slayer Mark. His Demon Slayer Mark took the form of a collection of differently-sized stars, stretching from his left ear and travelling down his neck and across his shoulder until it reached his left hand (the same Demon Slayer Mark as his father's) that then boosted all of Hikari's natural abilities, allowing him to access the Transparent World, and unlocking every memory he had of every technique he had ever learned across his lifetime. This was seen where he was able to land powerful sword slashes against Yūgen, switch between multiple Breathing Styles and techniques simultaneously, swiftly dodge and maneuver to avoid all of Yūgen's and later Muzan's immensely fast attacks, and increase his physical stamina and durability allowing him to fight despite being severely injured.

* **Bright Red Nichirin Sword:** By persisting during his fight with Yūgen while being marked, Hikari managed to link his Demon Slayer Mark with his blade, the sheer elemental power of it turning it bright red. Turning his Nichirin Sword bright red proved to be extremely effective against Yūgen and later against Muzan, allowing his attacks to hamper their quick regeneration and, during the battle against Muzan, giving the other Demon Slayers a chance to turn their blades bright red as well to increase their offensive output.
* **Transparent World:** Hikari managed to access the Transparent World after awakening his Demon Slayer Mark, giving him the ability to analyze Yūgen's anatomy and reach her vital organs as well as her neck.

**Enhanced Strength:** Despite his small stature and neglected physical strength due to his upbringing, Hikari possesses a great amount of physical strength, as shown when he pins a Lower Rank demon to the ground and rendering them unable to move or breathe. This was also shown during the Asakusa Arc, before Hikari had become a Hashira, where he discovered Susamaru and Yahaba on their way to kill Tanjiro, and was able to catch one of Susamaru's Temari balls without sustaining any sort of injury. Despite this, he is the the second-weakest Hashira in terms of physical strength, with only Shinobu being physically weaker than him.

**Supernatural Healing:** Hikari was known well through the district he was brought up in for having supernatural healing properties within his tears, and these properties were enhanced the more stamina he had. Because of this, Hikari was nicknamed "Fushichou" (不死鳥, *fushichou: lit. Phoenix*) due to the ability's resemblance to the mythical creature. Hikari healed people by letting his tears roll onto his fingertips, and then dropping them into someone's eyes. Although his fingertips are coated in an almost-lethal venom, the healing properties of his tears contradict and further neutralize its effects. The fact that both eyes had to receive Hikari's tears meant he could not heal himself; the scar across his right eye prevented him from doing so due to the lack of a pupil he had after it was slashed out. The effects of this ability are seen when Hikari is knelt over Zenitsu's unconscious body during the battle against Muzan, and his tears fall from his left eye into both of the former's, granting Zenitsu consecutive bursts of energy and strength when he awakens.

**Komorebi** (こもれび *Komorebi*)**:** Hikari, having been partially blind in his right eye since a young age, developed a combat technique utilizing the supernaturally-gifted chameleon he befriended, Komorebi. Komorebi possesses a unique ability which allows him to first disguise himself with Hikari's skin tone, and then merge his body with Hikari's neck, giving Hikari the ability to camouflage and disappear from an opponent's view for as long as he is merged with him. Komorebi, similar to Kaburamaru, can also relay information on opponents' incoming attacks using signals sent to Hikari through high-pitched trills only audible to Hikari himself, a language similar to morse code. The full extent of these abilities are shown when Hikari was able to disappear from Yūgen's view multiple times while fighting her, and also during the final battle against Muzan where Hikari was still able to fight effectively despite being almost completely blinded by the Demon King's slashes, and almost completely deafened by the constant direct hits of the demon's **Shockwave Energy Blasts**. Komorebi also seems to be capable of understanding human emotions and the limits of their lives, as shown when he shed tears while watching Hikari suffer from his injuries during the aftermath of the final battle, and merged with him one last time to grant him enough strength to relay his final message to Tanjiro.

**Temporary Amber Art:** While Marked, Hikari was able to absorb a portion of Yūgen's blood through his own wounds, and gain the temporary ability to utilize the demon's Blood Demon Art. This was also shown during the final battle against Muzan, where droplets of Muzan's blood entered Hikari's bloodstream and therefore gave him the temporary ability to block the Demon King's **Shockwave Energy Blasts** with the same attack.

**Immense Speed and Reflexes:** As a Hashira, Hikari possesses superhuman levels of speed and reflexes. When Obanai Iguro was about to get hit by what could have been a fatal blast from Muzan, Hikari was able to jump in and block most of the strike in time (although being unable to prevent all the damage from reaching the Serpent Hashira). Alongside Iguro, Hikari was able to keep up with Muzan Kibutsuji's whip attacks for an extended period of time without the boost granted by the Demon Slayer Mark as well as managing to land many hits on the Demon King. After awakening his Mark and gaining the sheer elemental power from it, Hikari was quick enough to subdue Muzan's instant regeneration for a few moments, allowing Iguro to slice off both of the demon's arms. Even when almost fully blinded and severely injured, Hikari was able to evade many of Muzan's attacks and fight back, even piercing two of the Demon King's hearts. Hikari was ranked 3rd in a race against his fellow Hashira.

**Immense Stamina & Endurance:** Hikari has displayed his phenomenal stamina and endurance on multiple occasions during the Infinity Castle Arc and final battle. Hikari was able to hold his own against Upper Rank Three, Yūgen, for an extended period of time and still had enough energy to help protect Tanjiro, Tomioka and Iguro. Additionally, at the surface, Hikari along with Iguro and their allies were able to stall Muzan for around half an hour, sustaining injuries from poison and his flesh whips.

When Muzan incapacitated him, Iguro, Tomioka, Shinazugawa, Himejima, Zenitsu, Inosuke and Kanao, Hikari was the second to recover after Iguro, which was long before any other Hashira did. He also possessed enough energy to use his tears to give Zenitsu Agatsuma the ability of bursts of strength and stamina that was prolonged until he came to. Afterwards, Hikari managed to possess enough stamina to fight back against Muzan when the Demon King targeted him, and managed to withstand the drastic effects that would usually come with assimilating even just a drop of Muzan's blood while using the demon's own technique against him. Nearing the end of the battle, Hikari still had enough energy to muster his unspoken final technique, one which could kill an inexperienced Demon Slayer due to its sheer extent. Out of all the Demon Slayers in that battle, Hikari lasted the second longest.

## Fighting Style

**Master Swordsman:** As a Hashira of the Demon Slayer Corps, Hikari was one of the most powerful and skilled swordsmen in the entire organization. This was shown during the Hashira Training Arc where, along with Obanai Iguro, was entrusted to teach all the other Demon Slayers about sword wielding techniques. Hikari makes use of a unique swordsmanship style that utilizes flowing motions to maneuver his sword and attacks in impossible ways, allowing him to move through the air with ease despite wielding a standard wooden sword. His swordsmanship prowess allowed him to keep up with the Demon King himself, Muzan Kibutsuji.

### Breathing Style(s)

**Sky Breathing** (空 の 呼吸 *Kū no Kokyū*): A Breathing Style Hikari created himself and mastered. This swordsmanship style makes use of unpredictable flowing or static movements similar to the changes in weather and the sky's state to attack in strange ways.

All internal injuries are healed in a matter of seconds, and any lost limbs are regenerated. The user's sword is also enveloped in the white flame, and generates bolts of electricity that strike the target without any necessary movement from the user. The user then rushes forward, aiming to decapitate the target.

**Love Breathing** (恋の呼吸 *Koi no kokyū*): A Breathing Style taught to Hikari by Mitsuri Kanroji during his time as her Tsuguko. Although not possessing Mitsuri's unique muscle density and therefore being unable to use the technique to its full potential, Hikari is incredibly potent in the technique and is consistent when using it.

* **Third Form: Purgatory Light** (参 ノ型 煉獄の光 *San no Kata: Rengoku no Hikari*): - The user drives their sword into the ground, generating bright, burning beams of light that grow stronger the further into the ground the blade goes.

All internal injuries are healed in a matter of seconds, and any lost limbs are regenerated. The user's sword is also enveloped in the white flame, and generates bolts of golden light that strike the target without any necessary movement from the user. The user then rushes forward, aiming to decapitate the target.
* **Unspoken Form** (暗黙の形式 *Anmoku no Keishiki*): - The user takes a powerful, low stance, energy from nearby stars as well as the user's strength charging within the user's blade and enveloping it in a white flame. The user then leaps up with the ability to stay airborne for as long as they use the form, slashing the air in front of them and sending a powerful beam of flaming light towards the target. While performing this technique, the user is able to perform other techniques of Star Breathing at the same time. This form can only be used by those who have mastered Star Breathing, due to the pure caliber and power of the technique having the ability to kill an inexperienced user. Because of this, this form is only used by Ren Kyoudo, Kintsugi Kyoudo and Hikari Kyoudo.

Hikari has also mastered multiple forms of different Breathing Styles due to the keen interest he took in the Hashira during his time as a lower-ranked Demon Slayer.

### Other Mastered Forms

Its effect and efficiency is enhanced underwater, where the user can draw water around their weapon to create whirling currents that enhance their slashes.
* **(Flame Breathing)** **Fourth Form:** **Blooming Flame Undulation** (肆ノ型 盛炎のうねり *Shi no kata: Sei En no Uneri*) - The user performs a singular slash or multiple if needed, in a fluid circular motion to defend from incoming attacks and decapitate multiple targets.
* **(Mist Breathing) Third Form: Scattering Mist Splash** (参ノ型 霞散の飛沫 *San no kata: Kasan no Shibuki*) - The user performs a powerful and swift circular slash that can blow away incoming projectiles.

### Temporary Blood Demon Arts

After managing to assimilate a small portion of the bloods of Yūgen, Upper Rank Three, and later Muzan Kibutsuji himself in the Infinity Castle Arc, Hikari was able to use techniques from both demons' Blood Demon Arts until the supernatural properties of his own poison neutralized the effects of theirs.

#### Yūgen's Blood Demon Art

* **Pointed Snowflakes of Indigo** (鋭い雪の藍色 *Surudoi Yuki no Aiiro*) - The user reaches out to the air in front of them, manipulating its particles to form a purple mist-borne snowflake that stands vertically in front of them. Using force from their hands, they tear the snowflake in two and send the pieces spinning towards their target, slicing through them.

* **Tainted Blossoms of Hinami** (汚染 花 のひなみ *Osen Hana no Hi Nami*) - The user spawns two duplicates of Yūgen's wooden pointed crucifix, now dual wielding it, and, using their points, drawing out the kanji for "flower" (花 *hana*) and using force from their hand to dissipate it. The mist then travels in violent, lightning-quick rays, hitting the target and diffusing into their skin.

* **Bloodstained Petrichor, Sourceless** (血塗れ ペトリコール, ソースレス) - A slightly modified version of Yūgen's form that utilizes the user's fingertip instead of a wooden crucifix. The user points their fingertip above them, generating powerful, violent rays of purple mist that direct themselves towards their target and strike them simultaneously, penetrating their skin and on occasion impaling them.

#### Muzan Kibutsuji's Blood Demon Art

* **Shockwave Energy Blast, Alterless:** A modified form of Muzan's form that is executed without the user morphing any part of their body. The user projects a long-ranged energy-like shockwave that severely damages the nervous systems of those caught in it, causing extreme seizures and convulsions, even rendering them unable to breathe for a brief period of time due to damage inflicted to the target's lungs.

## Equipment

* **Lightning-Strike Nichirin Katana:** Hikari carries around a heavily modified Nichirin katana similar in appearance to an Indonesian Kris Sword, with the sword's shape modeled into sharp waves resembling a lightning strike, which is white in color. His katana's handguard has a black star shape with a white outline, engraved with golden markings of the sun. This handguard was gifted to him by his father Kintsugi Kyoudo after he retired from the role of Star Hashira. As a Hashira, the words **Destroyer of Demons** (惡鬼滅殺 *Akki Messatsu*) are engraved on the side of the blade. Hikari doesn't carry a scabbard for his sword, and instead, similar to Tengen Uzui, wraps his sword in a bandage-like cloth that falls off the blade when it is drawn.

## Trivia

* Hikari's full name simply consists of the traditional kanji reading for "strength" (強度 *kyōudo*) and "light" (光 *hikari*).
* Hikari's chameleon is called Komorebi, and Hikari considers him as more of a friend than a pet. After Hikari's death, Komorebi is entrusted to Zenitsu Agatsuma.
* When Hikari was rescued by Kagaya Ubuyashiki, the latter at first believed he was an ex-member of the Twelve Kizuki due to the 'X'-shaped scar protruding from his eye.
* Hikari's sword was made by Hotaru Haganezuka. At first it was believed that Gantetsu, the son of Tecchin Tecchikawahara, was the forger of the sword due to its similarity to Obanai Iguro's sword.
* Hikari viewed the other Hashira as follows:
	+ *"A truly incredible teacher, and deceptively strong. I worry for any adversary she faces, for I know they will not survive her skill."* - Love Hashira
	+ *"He's a strange man. He always looks unhappy and sometimes it does irritate me. However, he is a very skilled combatant."* - Water Hashira
	+ *"We have grown quite close as friends due to our similar pasts and shared experiences. I truly value and trust him over all people. Not only that, his skill as a swordsman despite his physical handicaps is truly impressive and respectable."* - Serpent Hashira
	+ *"She always has a smile on her face, although I can easily tell behind that façade is a boiling anger and a raging fury. Despite this, she doesn't let her personal grudges affect her as a Demon Slayer. Her fighting style is very unique, too."* - Insect Hashira
	+ *"I have never once seen him disheartened or without his lively spirit. I like him. He's a very genuine guy, too. Someone who wouldn't pretend that everything was okay if it wasn't. We talk often."* - Sound Hashira
	+ *"He has a good personality and a strong will of justice. I have never seen a situation where he has not managed to smile."* - Flame Hashira
	+ *"Very strong and incredibly wise. I know I can rely on him."* - Stone Hashira
	+ *"Even though he's only two years younger than me, I do hope he doesn't die at his age. I view him as my superior. We don't talk often, though."* - Mist Hashira
	+ *"He's okay. I talk to him more often than most people. He seems quick to judge, though."* - Wind Hashira
* Hikari's level of openness was rated as 20%.
* Despite being described as the second-weakest member of the Hashira in terms of strength, Hikari, along with Obanai Iguro, was one of the only Hashira able to contend with Muzan without awakening his Demon Slayer Mark.
* In Kimetsu Academy, Hikari is a prodigy who is the replacement physics teacher whose topics mainly revolve around stars and outer space. He is often seen talking to Iguro at Aoi's restaurant, so it is believed that the two of them are good friends. In Hikari's class, when students fail tests, they are stood against a wall and pelted with "comets" which are really just water balloons.
