Since the day I was born I've never lied... not even once! I'm a good natured weakling! I deserve pity, but no one has any sympathy for me.
— Hantengu about himself in Get it Together, Moron!
Hantengu takes on the appearance of a short frail man with a very thin and skeletal body, covered with veins and wrinkles and is usually seen crouching. His most noticeable feature is a large bump on the top of his head, accompanied by two curved horns.
His face is thin with a sharp chin and constantly wears an expression of terror and fear, with a prominent brow ridge that lacks eyebrows. His eyes are narrow and often appear to be squinting, lacking any visible pupils. Hantengu also has the kanji for "fear" etched into this tongue.
He has dark shoulder length wavy hair with a low hairline, only growing out from the back of his head and ears, who themselves are sharper and longer then a normal humans. His nails are long but not sharp like most other demons and retain their natural square form.Clothing wise he wears a dark kimono that is split in the middle, the right half being covered in a pattern of flowers and lines with the left half being dark and lacking any detailed features. He also wears black hakama pants and a pair of zōri.
Sekido wears the same kimono as Hantengu, with the right half being covered in a pattern of flowers and lines with the left half being dark and lacking any detailed features. He also wears dark hakama pants and a pair of zōri. Sekido is always seen carrying around a Khakkhara (
Aizetsu wears a black kimono with white lines running through various areas of the clothing and rope-like accessories tied around his shoulders. He also wears hakama pants and a pair of zōri. Aizetsu is always seen carrying around a Jūmonji Yari (
Urogi has a bird-like physiology, possessing two large wings on his back and sharp talons that take the place of his hands and legs. Urogi only wears hakama pants tied together by a chain of large round pearls and a pair of zōri.
Zohakuten's clothing seems to be a combination of Sekido's, Karaku's, Aizetsu's and Urogi's clothes. He wears black hakama pants covered with a piece of cloth bearing a close resemblance to Sekido's kimono and tied together with a long strap of white cloth. He also wears long sleaves that bear a resemblance to Aizetsu's kimono. Finally, he dons on a plate of armor that is golden in color that only covers his chest.
Zohakuten has a series of drums connected to each other that is inexplicably floating behind his back, with each drum having the kanji of hatred displayed on them. He also carries around a bone-like accessory on each hand.
Hantengu's primary form has a persona of cowardice. He was easily frightened by what occurred in his surroundings, showing traits of paranoia, fear and delusion. He was always shown to cry out in fear at even the most insignificant things. This is especially evident in the fact that he always chooses to crawl instead of walking up straight. Even in combat, Hantengu was shown to be extremely cowardly and afraid, crying when he was slashed by Muichiro Tokito and when he was hiding from the Demon Slayers.Hantengu also seems to believe he is completely innocent despite the obvious evidence pointing towards his numerous crimes as a human. Even as a demon, killing and eating scores of innocent people, he still stubbornly and delusionally believed that he was innocent.
As the personification of Hantengu's anger, Sekido in a constant state of vexation, irritation and rage, even towards his fellow clones, which could be seen when he easily got angered when they failed to meet his expectations and got subdued by the Demon Slayers. Sekido is also seen to care very little about his brethren, shown when he forcibly absorbed them against their will even as Aizetsu protested. He also showed himself to be the most dominant of the emotion clones and appeared to be the leader, as he was the one who barked orders to them and took charge at critical junctures when they were battling the Demon Slayers.
As the personification of Hantengu's relaxation, Karaku showcased himself to be the most relaxed and laid back of Hantengu's clones. The entire time he was battling against Genya, Tanjiro and Nezuko, he was constantly praising them and, instead of taking the battle seriously, he instead saw it as nothing more than a game, seeming to only take interest in the new experiences he was obtaining from the battle. This could be seen when he happily expressed his interest at the new sensation upon being shot by Genya and commenting that was the first time he was ever injured in such a manner. This was demonstrated again, only this time during his battle with Nezuko, when, instead of finishing her off, he decided to tease and play with her despite being able to easily overpower her anytime he wanted.This behavior easily got on the nerves of his fellow clones, specifically to Sekido, who constantly berated him for taking so long in battle.
As the personification of Hantengu's sorrow, Aizetsu is portrayed to be completely dejected, sour and negative as he constantly described everything as being depressing. Out of all the emotion clones, Aizetsu was shown to be the most calm and collected out of all five of them, as seen where instead of frivolously wasting time on entertainment as Urogi and Karaku or immediately getting agitated and enraged by anything like Sekido, Aizetsu was shown to calmly analyze his opponents and think out his strategy and figure out his opponents abilities and weaknesses before attacking.
As the personification of Hantengu's joy, Urogi is the most jovial and giddy of Hantengu's clones. Similar to Karaku, he seemed to view the entire battle against the Demon Slayers as nothing more than a game or as a source of entertainment, as seen when he happily complemented Tanjiro on his intelligence for correctly guessing that neither one of the four clones were the "real" body, and constantly exclaimed that the entire fight against Tanjiro was delightful.
As the personification of Hantengu's hatred, Zohakuten shared many personality traits with Sekido, as he too was easy to enrage and was incredibly spiteful and hateful towards his enemies due to him, deeming them as "evil" for bullying his "weak and innocent" self. Like Sekido, he was also incredibly foul-mouthed as seen when he constantly insulted his opponents and referred to Mitsuri as a harlot, constantly calling her various degrading names in his thoughts.He also seemed to harbor an immense sense of loyalty towards Muzan, as seen when he told Mitsuri that he only heeds and follows the orders of one man in the entire world. Out of all the clones, he was shown to be the most intelligent and insightful aside from Sekido, as seen when he easily analyzed why Mitsuri survived his powerful attacks and figured out the true source of her strength.
As the personification of Hantengu's resentment, Urami was shown to be just as hypocritical and delusional as Zohakuten and Hantengu, as he angrily told Tanjiro not to bully and hurt his "weak and innocent" self. He angrily asked why Tanjiro couldn't "see" his innocence and, true to his name, he has shown to be the embodiment of Hantengu's resentment due to him being punished and persecuted for crimes that he was "innocent" of.
Overall Abilities: As the holder of the fourth highest title in the Twelve Kizuki, Hantengu is an extremely powerful demon and can be considered to have been the fifth strongest demon in existence. Through Hantengu's Blood Demon Art, he is able to create four clones of himself, all of them possessing the same caliber of strength as an Upper Rank demon. These clones were able to hold off and overwhelm the combined efforts of Tanjiro, Nezuko and Genya, all of whom are seasoned and trained combatants. Genya stated that Hantengu was particularly difficult to defeat as Demon Slayers would have to play cat and mouse looking for the main body while being chased down by four Upper Rank-level demons.
As another testament to their strength, when the four clones fused into one form, Zohakuten, he was able to once again capable of fending off all three Demon Slayers as well as the Love Hashira, Mitsuri Kanroji, one of the strongest Demon Slayers in the Demon Slayer Corps singlehandedly. Even after the Love Hashira awakened her Demon Slayer Mark, she could only evade and dodge Zohakuten's attacks and stall until the Demon Slayers defeated the main body, Hantengu. As Zohakuten and Tanjiro stated, Mitsuri would've run out of stamina and died if not for the sun rising and Hantengu being killed.
Enhanced Stealth: Hantengu possesses immense skill in being stealthy, which can be seen when he managed to easily infiltrate the swordsmith village, one of their most vital and well fortified bases, without any of the numerous Demon Slayers stationed there noticing. Hantengu later managed to sneak into Muichiro's and Tanjiro's room without any of them detecting him, despite the former possessing the ability to sense the presence of demons and the latter possessing an incredibly acute sense of smell that would've sensed a demon's presences from extremely long distances. His stealth ability is so strong that none of them realized Hatengu was a demon until they saw it.
Immense Durability: Hantengu possesses a body so durable that not even Genya's bullets could leave a dent on his body, the same bullets which tore of the necks of his clones. Even when Genya tried to cut off Hantengu's body with his Nichirin Sword, his katana broke before it could do any damage. Even with Tanjiro's bright red blade, he couldn't make a dent in his neck.
Immense Speed & Reflexes: As an Upper Rank demon, Hantengu possesses incredible movement speed and reflexes, being able to evade Muichiro's Mist Breathing technique and Tanjiro's Hinokami Kagura's technique without much effort. When he was in his tiny form, he could run fast enough that Tanjiro, Nezuko, or a demon blood-enhanced Genya could not keep up.Size Alteration: Hantengu has the ability to change his size at will, as shown when he became a tiny version of himself in order to hide from the Demon Slayers.
Biological Absorption: Sekido displayed the ability to draw in and absorb the bodies of Karaku, Urogi, and Aizetsu, fusing to become Zohakuten.
Flesh Manipulation: Like all demons, Sekido possesses the ability to control and alter his flesh to a certain extent. Sekido uses this ability to shape his flesh into a Khakkhara which he uses as a means to channel his Blood Demon Art. He is shown to be capable of creating more than one at a time.Immense Speed & Reflexes: As an Upper Rank demon, Sekido possesses superhuman speed and reflexes comparable to that of the Hashira. This was shown when he was fast enough to block the bullets from Genya's shotgun before they could reach him.
Flesh Manipulation: Like all demons, Karaku possesses the ability to control and alter his flesh to a certain extent. Karaku uses this ability to shape his flesh into a maple leaf-shaped Uchiwa. Similar to Sekido, Karaku can create more than one Uchiwa at a time, even creating an enlarged version of it to increase its area of effect.
Flesh Manipulation: Like all demons, Aizetsu possesses the ability to control and alter his flesh to a certain extent. Aizetsu uses this ability to shape his flesh into a Jūmonji Yari.Unlimited Stamina & Endurance: Like all demons, Aizetsu possesses infinite stamina and endurance. This was shown when he was able to engage in battle with Genya for an extended period of time without showing any signs of fatigue in the slightest. Aizetsu was also completely nonchalant when Genya destroyed his neck with his shotgun bullets, even managing to attack without his head intact.
Avian Physiology: Urogi has the ability to mimic the attributes and abilities of avian creatures, namely in his large feathered wings and sharp talons. These large wings grant Urogi the ability to fly at incredibly fast speeds while his talons are powerful enough to cut through diamond. A drawback to this ability is that his body has to be extremely light for him to fly, giving an opportunity for his opponents to use Urogi's flight ability against him.
Menacing Aura: Zohakuten possesses an extremely menacing and overwhelming presence. Tanjiro choked on his breath and felt immense pain in his heart from Zohakuten's mere gaze. His aura is so strong that Genya could barely stand and caused him to start sweating profusely.
Size Alteration: As Hantengu's last ditch attempt to escape from the Demon Slayers, Urami has the ability to greatly increase his size in order for Hantengu to hide in his heart.
Emotion Manifestation: Hantengu's Blood Demon Art allows him to manifest his emotions as powerful younger clones of himself with their own unique appearances, personalities and abilities. These clones are personifications of a certain emotion Hantengu has felt before, and mainly display that emotion. Each one is identified by a kanji tattoo on their tongue labeling their core emotion. Hantengu can control these clones however he sees fit, though he usually lets them act on their own will. However, he did control and command Urami's body to kill a bunch of swordsmiths after he was beheaded.
This ability is activated when Hantengu's head is cut off, where his head and body turn into two separate clones, with those clones splitting into two after they are decapitated. However, they are at their strongest when there are only four of them. Damaging the clones' tongues has shown to slow their regeneration speed momentarily. Additionally, his clones will never die as long as the main body is still alive, making it nearly impossible to fight and defeat Hantengu alone.It is later revealed that Hantengu developed this ability through being constantly cornered throughout his life, causing the intense emotions he felt to personify through his blood.
Lightning Generation: Sekido's Blood Demon Art allows him to generate lightning from his Khakkhara. The lightning generated have a wide area of effect and can cause those hit by it to lose consciousness or paralyze his opponents in an instant, allowing him to subdue multiple targets at once. One drawback to his lightning is that it cannot pass through anything made from his own cells, such as the body parts of any of Hantengu's clones.
Aerokinesis: Karaku's Blood Demon Art allows him to generate and manipulate wind using his flesh maple-leaf shaped Uchiwa. By simply swinging his Uchiwa down, Karaku can generate a gust of wind strong enough to blow Muichiro into a forest in an instant, leave gigantic craters, level an entire building, and crush Demon Slayer and demon alike under its immense pressure, even knocking them unconscious.Karaku is capable of using his Blood Demon Art tactically, turning the entie battlefield into gusts of strong wind that make it hard for his opponents to move. However, this ability can be used against him by anyone who has possession of his Uchiwa, as shown when Nezuko used Karaku's own fan to blow him away.
Spear Projection: Aizetsu's Blood Demon Art allows him to project the thrusting attack of his Yari over great distances, allowing him to attack his targets from afar.
Sonic Scream: Urogi's Blood Demon Art allows him to generate powerful sound waves from his mouth. The power from Urogi's scream is strong enough to make Tanjiro bleed from his nose and ear.
Wood Manipulation: Zohakuten's main Blood Demon Art grants him the ability to manipulate and alter wood from the flora in his surroundings by tapping one of the many drums on his back. This Blood Demon Art can be used both close ranged and far ranged. Zohakuten mainly uses this ability to shape the wood into 5 massive dragon heads that can stretch up to twenty meters in length. He uses his dragon heads to bite his targets or to swallow them and crush them inside their jaws. Zohakuten can also create dragon heads within the main dragon heads in order to increase its length. He also displayed the ability to manipulate branch whips to use to attack his targets.Ability Combination: As the combination of Sekido, Karaku, Aizetsu, and Urogi, Zohakuten can use enhanced versions of the Blood Demon Arts of all four demon clones as a part of his own Blood Demon Art. The dragon heads fashioned from wood that Zohakuten manipulates can unleash lightning strikes like Sekido, generate powerful gushes of wind that leave gigantic maple leaf-shaped craters like Karaku, emit powerful sound waves like Urogi, and manifest spear attacks out of thin air like Aizetsu. Zohakuten is also capable of using these abilities from his body, as seen when he generated Urogi's sound waves without the help of his wooden dragons.
- Weeping Spears (
激 涙 刺 突Gekirui Shitotsu?): Aizetsu violently thrusts his Yari, creating multiple long-ranged projections of the spear attack.
- Crazed Cry of Thunder Death (
狂 鳴 雷 殺Kyōmei Rai Satsu?): Zohakuten commands his wooden dragons to unleash bolts of lightning and powerful sound waves from their mouths.
- Countless Striking Trees (
無 間 業 樹Muken Gōju?): Zohakuten commands his wooden dragons to attack his target, making them rapidly grow bigger and multiply as they rush towards his opponent.
Khakkhara: Sekido carries around a Khakkhara fashioned from his flesh and blood. It serves as his main tool in combat when used in conjunction with his Blood Demon Art, allowing him to generate lightning from his Khakkhara itself at wide ranges to electrocute, paralyze and incapacitate his targets. They also seem to be sharper than it seems, as it can easily pierce through Nezuko Kamado's neck.
Uchiwa: Karaku possesses a maple leaf-shaped Uchiwa fashioned from his flesh and blood. It serves as his main tool in combat when used in conjunction with his Blood Demon Art, allowing him to generate powerful gusts of wind to launch his enemies a far distance and to level any battlefield and turn it into one full of torrents of wind, making it extremely difficult for his opponents to fight or even move. However, this Uchiwa can be used by anyone, which allows Karaku's opponents to use his wind Blood Demon Art against him.
Jūmonji Yari: Aizetsu carries around a Jūmonji Yari fashioned from his flesh and blood. It serves as his main tool in combat, being used to unleash close to mid-ranged thrusting or slicing attacks as well as allowing Aizetsu to block and parry attacks from his opponents. His Blood Demon Art works in conjunction with his Yari, allowing him to project and lengthen the spear's attack to attack his targets from afar.
- The alias "Hantengu" contains the On'yomi reading of the kanji for "half" (半 han?), "heaven" (天 ten?) and "hound" (狗 gu?). The last two kanji in his name means Tengu (
天 狗?), a winged yōkai that uses fans in battle. The aspects of the Tengu are shared between two of (and thus half of) Hantengu's four basic emotions (Urogi's wings and Karaku's fans), hence the name.
- Hantengu's first four emotions are derived from the "Yojijukugo (four-character idiom)" (
喜 怒 哀 樂kidoairaku?), which can be used to describe the range of human emotions people (rather demons in this instance) feel as a whole.
- The drums behind Zohakuten's back represent the Taiko drums of the Shintō kami "Raijin" (
雷 神?). Whenever Raijin strikes the drums levitating behind his back, lightning strikes upon both the human world and underworld.
- Muzan sees Hantengu as normal but sometimes he's so annoying it's intolerable.
- Even as a child, Hantengu lied to make those around him look bad and gain sympathy.
- Hantengu lied about his name, age, and background so much that he forgot about what his real name, age, or background really is.
- Hantengu has married and had children several times. This didn't last though as whenever he would be accused of dishonesty, he would feel as if he was mistreated and kill his wives and children in anger.
- This cycle of marrying, having children, and killing seem to have continued until he met Muzan.
- His appearance was described to look like an 87 year old man.
- (To himself) "Since the day I was born I've never lied... not even once! I'm a good natured weakling! I deserve pity, but no one has any sympathy for me."
