Physical Description

His physical appearance is dominated by a perpetually handsome, sunny smile that never wavers, even in the heat of combat—a trait so incongruous with his brutal fighting style that it earned him the nickname "Smiling Devil" among his classmates 3. He is later described as possessing refined features beneath an irrepressible sharpness, while his body undergoes major changes after inheriting demon blood 296 352.

• Smile: Always fixed as a "handsome, sunny smile," maintained without interruption even when forcibly dragging a defeated opponent up from the ground 3.
• Demeanor: Displays no negative emotions whatsoever during a fight; the cheerful expression remains constant, creating a stark contrast with the violent recycling of sparring partners until their stamina is exhausted 3.
• Demon Transformation: After acquiring the Ghost King Body, Araki develops demonic eyes, greatly enhanced physical traits, rapid healing, and the ability to produce bone spurs from his body 352 353.
• Regeneration: His regenerative capacity is sufficient to heal deep wounds almost immediately, surpassing the recovery ability associated with Kaguya Black Bone's second Shikotsumyaku awakening 353.

History

Transmigration and the Book of Sword Masters

Araki was an illustrator in his previous world who became known for his drawings of sword-wielding characters. After accidentally falling asleep while working through the night, he awakened in the Naruto world as an orphan outside the Kirigakure Ninja Academy and chose the name Araki Yachiru for himself 2.

Within his consciousness, he discovered the Book of Sword Masters, an illustrated book containing characters he had drawn and collected in his previous life. By summoning and defeating the swordsmen represented in the book's pages, Araki can inherit their combat knowledge, sword techniques, physical qualities, and certain supernatural abilities 2 3.

Early Swordsmanship Development

Araki's first Sword Master was Asuna, whose rapid rapier techniques allowed him to acquire Stardust Splash and Flash Thrust. After repeatedly dying during training within his consciousness, he became increasingly detached from the suffering of others and focused almost entirely on his own strength 3.

He began practicing against his classmates after exhausting the usefulness of stationary targets, gaining the nickname "Smiling Devil" due to his relentless and cheerful approach to sparring 3. He later began teaching Ringo Ameyuri Asuna's Flash Sword Style, establishing a teacher-student bond that continued into their later service in Kirigakure 6.

After challenging and defeating Himura Kenshin, Araki inherited Hiten Mitsurugi-ryu and advanced into a more complete swordsmanship path centered on combining sword techniques with shinobi arts 15 19.

Kirigakure Leadership

Araki developed a close working relationship with Karatachi Yagura, whose trust in his ability and judgment led to increasingly important responsibilities 114 286. Following the death of the Third Mizukage, Yagura appointed him commander of the Hunter-nin Squad, which Araki reorganized into the Blade of the Bloody Mist, an elite force centered on swordsmanship commanded by ninjutsu 286 291 293.

After Yagura eventually abdicated, Araki succeeded him as Fifth Mizukage. During his inauguration, he demonstrated Conqueror's Haki before representatives of the other nations, consolidating his authority over Kirigakure 532 536.

Later Developments

Araki's later pursuits expanded beyond conventional shinobi power. He awakened the Demon Eye, researched demon blood and Blood Demon Arts, established the Spirit Arts Academy in the Pure Land, absorbed the Tenseigan's power, and developed his Zanpakuto to Bankai 353 501 496 613.

During his journey involving Kaguya and the Otsutsuki, Araki killed Kinshiki Otsutsuki, demonstrating that his strength had reached a level capable of threatening elite Otsutsuki warriors 628.

Relationships

• Karatachi Yagura: Araki's political ally and trusted superior before Araki became Mizukage. Yagura appointed him commander of the Hunter-nin Squad and entrusted him with the Blade of the Bloody Mist's reorganization 286 291. He later selected Araki as his successor as Fifth Mizukage 532.
• Ringo Ameyuri: Araki's earliest student. He taught her Asuna's Flash Sword Style after she witnessed his Stardust Splash training, while Ringo supplied him with his first proper sword 6.
• Zabuza Momochi: A former academy peer whom Araki later instructed in assassination-oriented swordsmanship suited to Hidden Mist and Silent Killing tactics 38. Zabuza subsequently became one of the notable members of the Blade of the Bloody Mist 470.
• Kisame Hoshigaki: A longtime training companion and ally. Araki trained alongside Kisame and Zabuza in ninjutsu, while Kisame's dedication motivated Araki to refine and simplify his own techniques 26.
• Hozuki Mangetsu: A friend, student, and collaborator in swordsmanship and weapon research. Araki taught Mangetsu the Spiral Wave Sword and later consulted him regarding Samehada and the creation of improved Ninja Blades 86 182.
• Sasori: A close collaborator in Kirigakure's technological and military development. Araki facilitated Sasori's acquisition of materials for Human Puppets and later supported his establishment of the Technical Research Institute 282 287 470.
• Kana: An Uzumaki subordinate and researcher whose knowledge of sealing arts and Death God Masks aided Araki's investigation into soul-based power 370 385.
• Asuna, Himura Kenshin, Yasuo, Sasaki Kojiro, Yamamoto Takeshi, Tanjiro, Keqing, Demon Eyes Kyo, and other Sword Masters: Summoned opponents and sources of Araki's swordsmanship inheritances through the Book of Sword Masters 2 15 100 195 293 358 359.

Abilities

Combo Technique (Stardust Splash)

Araki’s foundational swordsmanship skill, inherited from Asuna, is a rapid multi-hit combo known as Stardust Splash. Initially limited to an eight-hit sequence 3 7, he later pushes his speed and coordination to achieve nine-, ten-, eleven-, and finally twelve-hit combos in combat against Himura Kenshin 15. The technique relies on relentless forward pressure and precise chaining of cuts and thrusts to overwhelm an opponent’s defense.

• Applications: Used to break through guards, maintain offensive momentum, and force enemies into a war of attrition. The increasing hit count allows Araki to adapt to faster opponents.
• Limitations: Requires close range and a steady rhythm; if interrupted or parried, the combo chain is broken. The original eight-hit version can be predicted by experienced swordsmen.

Dash Technique (Flash Thrust)

A high-speed thrust that covers roughly twenty meters in an instant, comparable to a Body Flicker Technique 3. Araki obtains this skill after defeating Asuna, but initially struggles to control it – his nerves cannot keep up with the speed, meaning he executes the thrust automatically without full conscious command 3. Later, he integrates it into his tactical repertoire, using it as a surprise attack.

• Applications: Sudden closing of distance, piercing through defenses, and countering ranged attacks. Effective when combined with feints or the Transformation Technique.
• Limitations: Early lack of control makes it difficult to adjust trajectory mid-thrust. Leaves the user committed to a linear path; if dodged, recovery is slow.
• Later Development: Araki eventually combines Flash Thrust with Wind Instant Body Technique and Gale Palm-derived movement methods, substantially improving its speed and practical control 26 57.

Hiten Mitsurugi-ryu

After defeating Himura Kenshin, Araki absorbs the Hiten Mitsurugi-ryu iaijutsu style and incorporates its useful techniques into his own swordsmanship 15 19. He evaluates each technique for practical use in the ninja world, adapting some and discarding others as unsuitable.

• Dragon Cry Flash – A powerful iaijutsu technique that Araki considers vital to master before fully exploring Kenshin's remaining techniques 12.
• Nine-Headed Dragon Flash – A strong multi-directional slash technique that Araki deems essential to learn for its versatility and power 12.
• Amakakeru Ryu no Hirameki – The strongest and fastest single attack within Hiten Mitsurugi-ryu, a two-stage iaijutsu that combines speed and power 12.
• Earth Dragon Flash (Water Dragon Flash) – A crowd‑control skill that strikes the ground to send shattered stones toward enemies. Araki adapts its principle into Water Dragon Flash for the Land of Water environment 12 26.
• Dragon Hammer Flash – A powerful downward strike from a jump; Araki dismisses it as leaving too many openings for a ninja 12.
• Flying Dragon Flash – A throwing technique; Araki finds it inferior to his own kunai skills and considers it a trash skill 12.
• Twin Dragon Flash – A scabbard-assisted technique to overcome the single-strike weakness of iaijutsu; Araki finds it unnecessary as he lacks that weakness 12.
• Dragon Soaring Flash – A powerful upward slash; Araki considers it worth practicing 12.

Advanced Sword Techniques

By the later stages of his training, Araki’s sword repertoire expands far beyond the initial styles. His status page lists numerous additional techniques 367:

• Wind-Slaying Sword Technique – A wind‑aligned sword style. Its known techniques include Whirlwind Slash, Wave-Severing Ring Cut, Gale Blade, Wind Slash, Rending Wave Slash, Last Breath, and other wind-enhanced sword attacks 37 86 100 162.

• Yunlai Sword Technique – Includes variations such as Lightning Stiletto or Lightning Wedge, Stellar Restoration, and Starward Sword 195 229 314.

• Secret Technique: Swallow Reversal – A precise three-pronged counter-attack technique inherited from Sasaki Kojiro 195 228.

• Shigure Soen Ryu – A complete water-based sword style. Araki learns its principles from Yamamoto Takeshi and uses its water-controlling applications as a foundation for the Blade of the Bloody Mist 293 314.

• Mumyo Jinpu-ryu Killing Sword – A lethal sword style capable of manipulating moisture and forming cutting blades. Araki later masters its ultimate secret technique, Yellow Dragon 359 499.

• Secret Technique: Rain-Cutting – A chakra-neutralizing sword technique trained to counter elemental, non-elemental, and potentially Yin-Yang Release chakra 113.

• Mind’s Eye – An enhanced perception ability. Its first realm, Self-Knowledge, creates a close-range sword domain in which subtle movements cannot escape Araki's awareness; he later works toward Knowing the Enemy, an expanded form of perception 269.

• Mastery of Soji – Sasaki Kojiro's accumulated swordsmanship mastery, allowing Araki to repeat techniques without making their openings easy for opponents to read 290.

• Breathing of the Sage – A cultivation method that enhances physical and spiritual energy through the absorption and circulation of natural energy 348 358.

• Secret Sword: Heaven Tilt – A self-created technique capable of mobilizing atmospheric power for an overwhelming sword strike 520.

• Sage Art Secret Sword: Dragon Slayer – A Sage-enhanced sword attack used to destroy Hashirama's Wood Dragon and heavily damage his Edo Tensei body 520.

• Applications: Each technique serves a specific role – ranged cutting, finishing blows, counterattacks, chakra neutralization, perception, or environmental manipulation. The variety allows Araki to adapt to almost any opponent.

• Limitations: Not all techniques are fully detailed in the context; their exact conditions and drawbacks remain unspecified.

Passive Abilities

Araki possesses several innate or acquired passive enhancements 367:

• Ghost King Body – A passive physical augmentation that greatly improves durability, strength, regeneration, chakra recovery, and bodily adaptability 352 358.

• Mibu Blood – A Mibu-derived passive ability that grants increasing power through slaughter 367.

• Mastery of Soji – A passive skill that refines his overall swordsmanship and technique execution 290 367.

• Applications: Ghost King Body and Mibu Blood provide passive combat advantages without conventional chakra expenditure; Mastery of Soji continuously improves the quality of his sword strokes.

• Limitations: Mibu Blood's growth is tied to slaughter, while the exact upper limits of Ghost King Body and its associated bloodline powers remain undefined 367.

Demon Eye and Blood Demon Arts

Araki publicly identifies his Ghost King-derived Kekkei Genkai as the Demon Eye. It grants him extraordinary regeneration and bodily enhancement, while also serving as the foundation for further bloodline development 353.

• Demon Eyes: Araki can create and scatter large numbers of independent Demon Eyes, linking their vision to his own and using them as wide-area surveillance tools 495.
• Bone Manipulation: His transformed body can generate bone spurs throughout his frame, resembling an extreme form of Shikotsumyaku 352.
• Flesh Manipulation: Araki can manipulate and transform flesh, including creating the Flesh Clone Alucard, who possesses bat-like wings and other vampiric traits 356.
• Demon Blood Reinforcement: He can use demon blood to strengthen blades and plans to grant this enhancement to members of the Blade of the Bloody Mist, allowing ordinary weapons to gain cutting power without chakra-metal construction 352.
• Blood Demon Arts: Through experimentation, Araki successfully replicates several Blood Demon Arts derived from the Twelve Kizuki 352.

Sage Mode

Araki combines Breathing of the Sage, natural energy, and swordsmanship into his own Sage-enhanced combat methods. Unlike conventional summoning-based senjutsu, his approach is centered on personal cultivation and the direct integration of natural energy into sword techniques 116 348.

• Sage Mode: Tide of the Sun – A powerful Sage Mode used to defeat multiple elite Iwagakure shinobi, including the Four-Tails and Five-Tails jinchuriki, with decisive ease 458.
• Wrath of Heaven Research: Araki studies the Tsuchigumo Clan's natural-energy absorption technique as a possible route to expanding his senjutsu and swordsmanship, though the technique initially lacks a proper chakra-and-natural-energy fusion method 314.

Soul and Spiritual Abilities

Araki's later growth expands into spiritual combat and soul-based power.

• Blade of the Soul: A realm recorded by the Book of Sword Masters that allows Araki's swordsmanship to affect spiritual bodies directly. He can form soul blades capable of pinning an opponent's spiritual body in place 520 532.
• Spirit Devour: Araki can consume and assimilate spiritual power, though he initially finds a Death God's soul too powerful to absorb safely 370 475.
• Zanpakuto: Kenpachi: After absorbing Unohana Retsu's soul, Araki gains the Zanpakuto Kenpachi. It initially manifests at Shikai and later develops into Bankai 500 532 613.
• Tenseigan Power: Araki absorbs the power of the Tenseigan after meeting Otsutsuki Hamura. The process repeatedly destroys and regenerates his head until the absorption is complete 496.
• Three-Color Haki: After defeating the Lone Red, Araki awakens Armament, Observation, and Conqueror's Haki, the last of which he displays during his inauguration as Fifth Mizukage 536.
• Voice of All Things: An advanced sensory talent inherited from the Lone Red. It initially overwhelms Araki by exposing him to the thoughts and voices of those around him 536.

Ninjutsu and Other Skills

In addition to swordsmanship, Araki has trained in standard shinobi arts 7 367:

• Chakra Refinement Technique – Basic energy cultivation.

• Three Body Techniques – Clone, Substitution, and Transformation techniques, which he uses frequently in combat, including kunai-based Transformation feints 3 15.

• Shadow Clone Technique – Araki can create hundreds of Shadow Clones, using them as a training and research accelerator 352.

• Wind Style Ninjutsu – Includes Gale Palm, Grace of the Wind, Wind Instant Body Technique, and sword-enhancing wind chakra applications 26 37 57.

• Lightning Style Ninjutsu – Supports his Yunlai Sword Technique and thunder-enhanced sword attacks 195 229.

• Water Release – Used for Water Dragon Flash, water-based substitution, and swordsmanship support 26 293.

• Rasengan: Araki possessed and later sold the Rasengan's training method to the Hozuki Clan, while adapting its principles for Mangetsu's Spiral Wave Sword 86.

• Face-Face Fruit: A spatial ability that allows Araki to teleport directly behind a target, as demonstrated against Rasa 490.

• Applications: Ninjutsu supplements his sword skills – the Transformation Technique is key to his tactics against Asuna and Kenshin 3 15; Wind Release provides speed, ranged cutting, and mobility; Lightning Release improves his elemental versatility; and spiritual abilities allow him to confront non-corporeal enemies.

• Limitations: His primary focus remains swordsmanship. Several later supernatural abilities, particularly the Tenseigan, Bankai, and Voice of All Things, have not had all their conditions or limitations fully detailed.

Equipment

Wind Blade: Piercer

Araki acquired the chakra-conductive Wind Blade: Piercer from the Hozuki Clan for five million ryo. The sword's wind affinity allowed him to create highly lethal wind-coated edges at lower chakra cost than conventional Wind Release 36 37.

The weapon later revealed a hidden flaw when it snapped during a clash with Yasuo's Wind Slash, prompting Araki to seek a reforging solution 57.

Yachiru

After the Wind Blade and the Sword of the Thunder God were reforged together, Hozuki Ryuzuki created a compact hilt containing their combined material. By injecting chakra into it, Araki can generate an extremely sharp blade of light whose length and color change according to the amount and nature of chakra supplied 287.

The weapon is identified as Araki's light sword, Yachiru, during his battle with Sasaki Kojiro 290.

Samehada

Araki temporarily wielded Samehada during the competition to select the Ninja Swords' wielders. He rapidly learned its use from Hozuki Mangetsu and used it to disqualify Takano Kazuhiko 182.

Although he later returned Samehada to Suikazan Fuguki and was officially stripped of the weapon following the Third Mizukage's death, he showed little attachment to it because his personal sword path did not depend on any one blade 284 286.

Zanpakuto: Kenpachi

Araki gains Kenpachi after absorbing Unohana Retsu's soul. The Zanpakuto reflects his survival instinct and his desire for a sharp blade capable of eliminating all obstacles 500. It progresses from Shikai to Bankai as Araki's spiritual swordsmanship develops 532 613.

Power Progression

Stage	Key Events	Power Level
Swordplay Novice	Defeated Asuna in the first Sword Master battle, absorbing her rapier techniques and acquiring the Combo (Stardust Splash) and Dash (Flash Thrust) skills. Also learned basic Chakra Refinement and the Three Body Techniques (Clone, Substitution, Transformation). The Book of Sword Masters recorded his realm as "Swordplay Novice" despite having learned all of Asuna's abilities 3.	Could cross 20 meters in an instant with Flash Thrust, a speed comparable to the Body Flicker Technique. However, the movement was purely reflexive and not yet fully controlled. Still classified as a novice in the sword 3.
Swordsmanship Mastery	After fully digesting Asuna's swordsmanship, Araki's realm rose from Swordplay Novice to Swordsmanship Mastery. He then challenged the second Sword Master, Himura Kenshin, in pursuit of the Hiten Mitsurugi-ryu style 7.	His base swordsmanship, precision, and control had progressed far beyond an academy student. However, Kenshin's iaijutsu, explosive power, and Amakakeru Ryu no Hirameki still defeated him during their initial confrontation 7.
Sword Heart Initial Clarity	Defeated Himura Kenshin, absorbed Hiten Mitsurugi-ryu, and expanded Stardust Splash from eight to twelve hits. His status consolidated Asuna's and Kenshin's foundational skills under Draw-Sword Skill, while Dragon Cry Flash remained distinct 15 19. He later trained Wind Release with Kisame and Zabuza, developed Gale Palm applications, acquired Wind Blade: Piercer, and awakened Wind Sword Intent through Yasuo's swordsmanship 26 37 100.	Araki could seamlessly combine swordsmanship, Wind Release, iaijutsu, high-speed movement, and ranged wind slashes. His improved wind chakra could produce cyan wind blades and techniques such as Rending Wave Slash and Last Breath, giving him high-level jonin-class offensive power 86 100 162.
Clear Mirror Still Water	Achieved Clear Mirror Still Water after a lethal duel with Sasaki Kojiro and gained deeper insight into Mind's Eye and Mastery of Soji 290. He subsequently acquired Lightning and Rain Sword Intents, the Yunlai Sword Technique, Swallow Reversal, Shigure Soen Ryu, and Rain-Cutting 314.	Clear Mirror Still Water grants true immunity to conventional genjutsu and eliminates one of Araki's former weaknesses 290. His elemental swordsmanship, perception, and refined technique allow him to dominate most opponents in close combat while retaining long-range options.
Ghost King and Mibu Expansion	After defeating Tanjiro and Nezuko, Araki gained Breathing of the Sage and the Ghost King Body 358. His confrontation with Demon Eyes Kyo further led to the acquisition of Mumyo Jinpu-ryu Killing Sword and Mibu Blood 359 367.	His physical body gains overwhelming resilience, regeneration, and strength, while Mibu Blood lets him become stronger through slaughter 353 367. The combination of demon physiology, Sage cultivation, and advanced sword styles significantly raises his endurance and killing power.
Demon Eye Awakening	Araki formally revealed the Demon Eye as his Kekkei Genkai and began distributing samples of his blood for Kirigakure-led research 353. He developed Blood Demon Arts, flesh manipulation, bone spur generation, Demon Eye surveillance, and demon-blood weapon reinforcement 352 356 495.	His regeneration and physical constitution exceed those of many established bloodline users, while his Demon Eyes and Flesh Clone expand his reconnaissance, mobility, infiltration, and battlefield support capabilities 353 356 495.
Sage Mode: Tide of the Sun	Araki completed a more powerful Sage Mode application and used Sage Mode: Tide of the Sun against Iwagakure's forces 458.	He effortlessly defeated multiple high-level Iwagakure shinobi, including the Four-Tails and Five-Tails jinchuriki, while retaining sufficient control to spare them afterward 458.
Blade of the Soul	After researching Death God Masks and consuming spiritual power, Araki developed soul-based combat methods, obtained the Zanpakuto Kenpachi, and reached the Blade of the Soul realm 475 500 532.	His swordsmanship can directly affect spiritual bodies, allowing him to use soul blades against entities that conventional physical attacks may not adequately harm 520 532.
Tenseigan and Three-Color Haki	Araki absorbed the Tenseigan's power after meeting Otsutsuki Hamura, then defeated the Lone Red and awakened Three-Color Haki and the Voice of All Things 496 536.	His physical, spiritual, sensory, and leadership-based power all increase sharply. Conqueror's Haki alone is sufficient to overwhelm observers during his Fifth Mizukage inauguration, while Voice of All Things gives him extraordinary but initially difficult-to-control perception 536.
Bankai and Slaughter Sword Intent	After comprehending the Bankai of Kenpachi, Araki's Book of Sword Masters status records Sword Intent in Wind, Water, Lightning, and Slaughter, alongside Bankai and Three-Color Haki 613.	Araki possesses an exceptionally broad arsenal of elemental, spiritual, demonic, Sage, and Haki-based power. By this stage, he is capable of killing elite Otsutsuki combatants such as Kinshiki 613 628.
