Akaza Infinity Train Appearance (Anime).png
You're misunderstanding something, Tanjiro. The only people I hate are weaklings. I only spit in the faces of the weak. Yes. I’m repulsed by weaklings. They make me vomit. The laws of nature dictate that they will be eliminated.
~ Akaza to Tanjiro Kamado


Akaza ( Akaza?) is a major supporting antagonist of Kimetsu no Yaiba. He is a demon affiliated with the Twelve Demon Moons, holding the third highest position, Upper Moon 3 (じょうげんさん Jōgen no San?). As a Demon Moon, Akaza is one of the closest servants of the Demon King, Muzan Kibutsuji, whose main purpose is to find the Blue Spider Lily so that Muzan can gain immunity from the sun.

Over a century ago, Akaza was a human by the name of Hakuji (はく Hakuji?), a prodigious martial artist who trained under Keizo while nursing his daughter, Koyuki, who would later become Akaza's fiancée.

Powers and Stats

Powers and Abilities:

  • Superhuman Physical Characteristics
  • Acrobatics
  • Supernatural Willpower
  • Master Martial Artist (Is a martial arts prodigy and has over a century worth of bare-fisted martial arts experience. Was able to beat up a group of bloodlusted adults when he was 11 and mutilated 67 adult swordsmen all at once when he was 18)
  • Enhanced Senses (Demons can easily smell blood and poison being able to differentiate more or less nutritious blood types. Was able to locate Giyu and Tanjiro from a relatively far distance)
  • Extrasensory Perception (Able to sense the presence of others and malicious intent, this can be used to differentiate humans and demons, determine how strong someone is to a certain extent or detect an enemy in the vicinity)
  • Immortality (Type. 1, 2, 3)
  • Regeneration (High-Mid; Even after being reduced to a decapitated head, a low-level demon would have still been capable of regenerating if his head were to be "completely crushed")
  • Self-Sustenance (Type 3, Demons don't sleep)
  • Body Control and Limited Transmutation (A low-level demon could grow hands from its head after it lost its body. Superior to demons who can use their flesh to form clothes, rope, and metallic weapons. Created clothes from his flesh)
  • Battle Spirit (Overwhelming Aura that causes the opponent fear and paralysis with them feeling the air getting heavier, and can even cause internal bleeding and external lacerations)
  • Instinctive Reaction (Superior to Kyojuro, Mitsuri, Sanemi, and Giyu who can react instinctively)
  • Shockwave Manipulation (Akaza's Blood Demon Art allows him to generate and manipulate blue shockwaves that take on multiple forms, such as nigh-invisible air pressure, cannon-shaped spikes, or flowing streams)
  • Danmaku (Akaza can unleash dozens of shockwaves at once. Can surround his opponent with a hundred blows striking everywhere at the same time with Chaotic Blue Metal Afterglow)
  • Weakness Detection, Strength Perception, Precognition, Reactive Power Level, Enhanced Instinctive Reaction, Enhanced Awareness and Enhanced Accuracy with Compass Needle (Compass Needle allows him to accurately sense a person's Battle Spirit, allowing him to predict their movements, discern their location in his surroundings (even from his blind-spots), and find and instinctively aim for their weak points and vitals with such high accuracy that his attacks are described as "being attracted by magnets" and "clinging" to his opponents. Can tell someone's strength just by looking at them, was able to discern that Kyojuro was a Pillar at a glance. Can instinctively respond to attacks with an appropriate counter, was stated by Giyu to learn to anticipate his every move and strike back with equal accuracy as the fight went on. He can effectively fight and discern his surroundings and track his opponents without a head (deaf and blind) solely through detecting Battle Spirit)
  • Adaptation (Adapted to being beheaded by a Nichirin Blade which would normally kill a demon. Can make himself immune to poisons he didn't experience by being telepathically informed about its properties)
  • Limited Information Analysis (Demons can perceive details like blood type, sickness and genes)
  • Limited Sound Manipulation (His scream was able to hurt Tanjiro's ears from a distance)
  • Limited Telepathy (Can share his thoughts and sight with lower ranked demons if Muzan permits it)
  • Limited Corruption (Type 1) and Power Bestowal (Muzan can choose to transform a human into a demon if an Upper Moon gives them their blood)

Resistance to Disease Manipulation (Demons don’t get sick), Poison Manipulation (Superior to strong demons who have high poison resistance. Should be far superior to Gyutaro who shook off a poison dosage that would paralyze an ordinary demon for half a day within moments, and is inferior but somewhat comparable to Doma who can eventually adapt to poison strong enough to kill the average demon 700 times over), Pain Manipulation (Was unbothered by wounds made by Tanjiro's Dance of the Fire God techniques, which were stated to be especially painful by Daki), Regeneration Nullification (Up to High-Mid; Could regenerate from Tanjiro's Dance of the Fire God techniques which nullify regeneration), Fear Manipulation and Paralysis Inducement (Despite being paralyzed in fear by Muzan's aura, he's immune to the aura of Lower and Upper Moons that cause a similar effect but on a much lesser scale)

Attack Potency: Multi-City Block level (Overwhelmed Marked Giyu while holding back)

Speed: Massively Hypersonic+ (Comparable to Marked Giyu)

Lifting Strength: At least Class 25, likely Class 100 (Superior to Kyojuro and Marked Giyu)

Striking Strength: Multi-City Block Class

Durability: Unknown, Multi-City Block level with his neck (While the durability of a demon's body is inconsistent and can be hurt by weaker foes, their necks are their most durable body part and can tank attacks from characters who are comparable to their AP)

Stamina: Infinite (Demons don't tire)

Range: Standard Melee Range, Tens of Meters with his Blood Demon Art

Standard Equipment: None Notable

Intelligence: Gifted (With over a century of combat experience and martial arts training under his belt, Akaza is able to fight effectively with foresight and tactical intelligence. This even surprised Giyu, who stated that Akaza could instantly evolve and adapt to any attack or technique that he uses, to the point that he can predict when his opponents will strike and how to counter them with equal power. Before he became a demon, Akaza has displayed natural aptitude in martial arts, shown when he was capable of beating up trained swordsmen from neighboring dojos while still in the midst of learning Keizo's Soryu Style. This is further exemplified when he could fight and defeat grown men without martial arts training)

Weaknesses: Sunlight reduces him to ashes. Wisteria is poisonous to him. When reminded of his days as a human, and his late fiancé, he loses the will to fight and allows himself to die.

Notable Attacks/Techniques:

Compass Needle (しん Rashin?): Akaza manifests a light blue snowflake-shaped compass underneath him with numbers ranging from 1 to 12. This technique allows Akaza to sense a person's "Battle Spirit (とう Tōki?)", a person's will to fight, which he uses to achieve numerous effects while in combat. Firstly, he is able to determine the strength of anyone at a glance, such as when he discerned that Kyojuro was a Pillar just by looking at him. Secondly, Akaza is able to detect the presence of his opponents in his immediate surroundings (even in his blind spots) and can use this to predict where and how his opponents will strike him. This technique also allows Akaza to tell where his target's weaknesses are located and instinctively aim for them. Furthermore, the precision of Akaza's attacks are greatly enhanced, to the point where Tanjiro stated that it was like magnets were pulling his fists towards his vitals, and even described them as having "unparalleled precision". This is hinted at when a slight scrape from his kick (even while his sword had blocked it) caused Tanjiro to bleed. Moreover, Tanjiro also stated that Akaza was able to pierce through any opening in his attacks without fail. Another trait of his Compass Needle allows him to reactively adapt to his opponent's attacks, learning to anticipate their techniques and attack forms and even strike back with equal accuracy over time. Additionally, the stronger a person's Battle Spirit, the stronger the response of his Compass Needle. His Battle Spirit detection is so accurate that he can find the location of Tanjiro in his surroundings and fight and overpower Giyu without a head, meaning that he is performing those feats while basically being deaf and blind.

Void Style (くうしき Kūshiki?): Akaza punches the empty air in front him, creating a shockwave that flies towards his enemies and hits them from afar. These airborne shockwaves can be created multiple times in quick succession and can be unleashed in the sky or on the ground.

War Style (らんしき Ranshiki?): Punching rapidly in front of himself, Akaza creates a barrage of large shockwaves. This attack was capable of overpowering Kyojuro's Flame Tiger technique.

Obliteration Style (めっしき Messhiki?): One of Akaza's most powerful techniques. Akaza crouches with both his arms at the side of his body poised to strike. He then lunges forward, creating two powerful circular shockwaves from the palm of his hands which he uses to strike his target with tremendous force. This technique was strong enough to go through Kyojuro's most powerful attack, Purgatory.

Leg Form: Cap Tip Slice (きやくしき かむろさきわり Kiyakushiki: Kamuro Saki Wari?): A reverse, rising axe kick that produces a shockwave once it connects with the target.

Leg Form: Flowing Light Flash (きやくしき りゅうせんぐんこう Kiyakushiki: Ryūsengunkō?): A flashing flurry of powerful straight kicks so fast that they create afterimages, with each kick producing powerful shockwaves. This technique was powerful enough to launch Giyu an extremely far distance.

Dual Layered Demon Wick (しんしん Kishinya Eshin?): Akaza unleashes eight powerful punches, each strike creating large and strong shockwaves in a similar fashion to his War Style technique.

Crush Style: Willow of a Thousand Flashes (さいしき まんようせんやなぎ Saishiki: Manyōsen Yanagi?): A powerful downward punch that delivers a large shockwave into the ground which expands outward.

Leg Form: Ring of a Thousand Flying Planets (きやくしき 飛遊ひゅうせいせんりん Kiyakushiki: Hyūsei Senrin?): A kick that utilizes a flowing motion which strikes Akaza's target from below and launches them upward.

End Style: Chaotic Blue Metal Afterglow (しゅうしき あおぎんらんざんこう Shūshiki: Aogin Ranzankō?): Akaza's ultimate technique. Akaza unleashes an omni-directional barrage of countless thin and sharp shockwaves that deliver a hundred blows to his target coming from everywhere almost at the same time. This attack was so powerful that it could negate Giyu's Dead Calm technique, a move known for its immense defensive capabilities.
