Power Progression

Stage / Realm / Level	Chapter	Notes
Heroic Spirit Summoning selected	2	Chooses summoning over Eye of Insight and Cosplay Mastery. His first attempt consumes all his cursed energy and produces extra-spicy mapo tofu.
Cursed-energy reinforcement	5	Instinctively learns to reinforce himself while fighting the cursed spirit threatening Sakura; his control improves during combat.
First Heroic Spirit possession: Red Archer	6 8	A blood-assisted summoning lets Archer possess him as a Pseudo-Servant and wield Unlimited Blade Works. The manifestation ends when Kaze reaches his limit.
King of Knights possession	16 17	Gains access to a holy sword capable of annihilating a cursed spirit and Sukuna’s Finger. Its destructive power reaches Special Grade level, although the higher-ups dispute the result.
Combat and Projection training	18	Trains with Heroic Spirits in his mental space and with Maki and Gojo at school. Learns Projection and can barely fight evenly with Yuta during training.
Vision and Geo shielding	35 36	Receives a Vision after attracting a god’s attention. Develops a golden shield that reinforces his body and weapons, allowing low-grade Black Keys to withstand Playful Cloud.
Karna possession	60 64	Karna agrees to lend him power after judging his purpose non-evil. Golden Armor provides formidable defense, but Karna’s disposition makes reasonable requests difficult to refuse.

World permissions	150	Uses newly acquired permissions to locate Brain in a hidden Kamo Clan chamber.
Popularity-driven spirit-power surge	157 158	His strength suddenly doubles after increased attention from higher-dimensional audiences. He identifies spirit power—not cursed energy—as the reserve that has increased.
Independent Vision development	169 172	Explores spatial and underground-detection applications, supplies Enkidu with power for a human manifestation, and later uses Rock Sealing and Rock Cage to contain an opponent.
Special Grade recognition	185	Rei Furuya’s information identifies him as one of the strongest Special Grade Sorcerers; the exact promotion event is not shown in the supplied material.
World pillar and future Heroic Spirit self	196	Gojo’s acknowledgment of him as “the strongest” removes the final barrier. Kaze gains access to his future Heroic Spirit self, rank A Clairvoyance, and an innate advantage over jujutsu sorcerers through “the strongest in jujutsu.”

Background / History

Original Life and First Transmigration

Kaze’s original parents died saving another person, leaving him an orphan. Although he did not hate them, their deaths shaped his opposition to self-sacrifice beyond one’s capabilities. He grew into a law-abiding person who helped others when doing so was within his means 42.

His first transmigration took him to the Detective World. Without an apparent special ability, he studied, skipped grades, attended university, and entered working life. Repeated murders around him eventually drove him to seek safety by becoming acquainted with Shinichi Kudo. He moved to Beika Town and became friendly with his neighbor Ayumi 166 185.

By his first successful Heroic Spirit summoning, he had crossed worlds twice and experienced three worlds 6.

Constructed Identity in Jujutsu Kaisen

The World Consciousness assembled Kaze’s new background through transactions with two deceased people: a Chinese heiress abandoned in Japan and a gifted, withdrawn boy who had been Sakura’s neighbor. The boy surrendered his “existence” in exchange for saving Sakura from her destined death 20.

The resulting records portrayed Kaze as a mixed-race child whose mother died young, leaving him an inheritance and an unusually advanced educational history. His body was adjusted to thirteen years old to match those records 20 38.

The abandoned woman’s partner was later revealed to be Toji Fushiguro. She and her unborn child had died, making Kaze’s supposed descent from Toji an identity arrangement rather than his actual origin. Kaze rejects Toji as his father but genuinely accepts Megumi as his brother 145 147.

Appearance

Kaze has a youthful, handsome appearance that makes him look younger than his school placement suggests 20 32.

• Natural features: Straight black hair and black eyes 80.
• Face: A baby face and cute smile; his looks are compared to a well-behaved top student or school heartthrob 20 32.
• Stature: Shortest among his classmates during the confrontation with Toji, despite having grown to 164.5 cm 145.
• Early clothing: Wears a ruby pendant and a long coat in summer so he can carry the Book of False Vassals inside it 3.
• King of Knights possession: Golden hair, clear green eyes, an azure coat, and silver light armor 16.
• Karna possession: White hair and gleaming golden armor 60.
• Dazai possession: Retains dark coloring, but his normally straight hair becomes naturally curly 80.

Personality

Kaze considers himself an ordinary person rather than a natural hero. He is cautious about danger, recognizes stronger opponents, and readily seeks allies instead of treating dependence on others as shameful. Nevertheless, Sakura’s peril rekindles his youthful wish to become a hero and pushes him to risk his life 4 6 23.

His politeness often conceals calculated provocation. He bluffs the conservative higher-ups with a projected holy sword, exploits binding-vow conditions, and patiently encourages Husky to lower his guard before extracting information. His classmates describe him as innocent-looking but sinister underneath 18 54 112 129.

He places family above romantic love and resents actions that leave dependents behind. His feelings toward selfless people are conflicted: he appreciates their kindness but distrusts idealism that ignores consequences. Despite initially describing himself as completely alone, he forms strong attachments to Megumi, Gojo, and the Oogami family 42 54 104 145.

Kaze enjoys games, attractive characters, and fluffy animals, particularly Panda. He can also misread social situations: he mistakes romantic gossip for combat questions and initially misunderstands Megumi’s anger after his battle with Sukuna as something to answer with explanations rather than an apology 18 29 62 180.

Abilities & Skills

Heroic Spirit Summoning

Kaze’s principal technique calls Heroic Spirits from other worlds. He eventually concludes that the system supplied summoning knowledge rather than creating the underlying talent for him 8.

• Early manifestation: World rules initially prevent Servants from appearing directly, so they lend him power through Pseudo-Servant possession 8.
• Energy conversion: The ritual reverses his cursed energy into positive energy, then gathers stronger positive energy called Spirit Power 68.
• Compatibility: Summoning depends on whether a spirit answers; compatible experiences, resolve, incantations, and relics can matter 6 8 39 60.
• Failed summons: The World Consciousness exchanges items for the unusual power he expends, producing the technique’s early gacha-like results 14.
• Teaching: Kaze agrees to teach Misato Kuroi summoning and recommends increasing Riko Amanai’s recognition through a manga or novel 183.

Borrowed Heroic Spirit Powers

Spirit / Form	Powers and Applications	Limits
Red Archer	Unlimited Blade Works, Projection Magecraft, and combat instruction 6 18	Effective use requires Kaze’s own weapon knowledge and combat proficiency. He cannot freely reproduce his initial battlefield manifestation early on 18 33.
King of Knights	Holy-sword attacks capable of destroying Sukuna’s Finger 16	Requires sufficient energy and an enemy satisfying the sword’s restraints; Kaze describes its ultimate attack as requiring a fight to protect the world 18 33.
Karna	Golden Armor and a powerful combat possession state 60 64	Influences Kaze toward granting reasonable requests. Karna’s form alone is insufficient assurance against opponents such as Sukuna 60 140.
Osamu Dazai	No Longer Human nullifies cursed energy, suppresses techniques and regeneration, and clears abnormal mental influence 80 112 160	The form weakens Kaze’s constitution. Switching to it sacrifices the protection supplied by Karna’s possession state 86 160.

Reverse Cursed Technique

Kaze learns healing by recognizing that his summoning ritual already performs part of the required energy conversion 68.

• Heals both himself and other people, including Shoko and Natsume 68 123.
• Functions independently of his current Heroic Spirit possession 85.
• Repairs severe injuries after he performs crude surgery with Megumi’s assistance 86.
• Does not prevent pain from incapacitating him before he can begin treatment 85.

Vision and Geo Techniques

His Vision is bestowed after a god notices him, an unusual case compared with Visions arising directly from their bearers’ wishes 36.

• Stele Shield: Covers his body and weapon in golden energy, improving protection and weapon durability 35.
• Detection: Trains spatial and underground-detection applications with Rabbit Escape bunnies 169.
• Rock Sealing: Seals a space with elemental power to prevent escape 172.
• Rock Cage: Raises stone pillars and walls around a target 172.
• His early shield is explicitly weaker than Zhongli’s 35.

Spirit Power and Higher-Dimensional Nature

Kaze’s underlying advantage comes from his higher-dimensional soul rather than the system itself 161.

• Higher-dimensional audience recognition increases his spirit power 157 158.
• Supplies Enkidu with enough spirit power to manifest in a youthful human form 169.
• Connects cursed energy, faith, despair, and other emotional power systems through their shared dependence on emotion 169.
• Gives Geto a meditation method and proposes using spirit power to nurture subdued cursed spirits into spirits or gods; this is a proposed development path, not an immediately demonstrated result 118.

Barriers, Teleportation, and World Permissions

• Uses teleportation arrays for travel and rapidly returns to Junpei when danger arises 84 87.
• Hides a Teleportation Circle at school to retrieve Sukuna’s Finger without attracting suspicion 129.
• Creates a barrier around the World Consciousness’s vessel and begins forming another to contain Uraume 144 160.
• Uses world permissions to track Brain to a concealed Kamo Clan chamber 150.

Future Heroic Spirit Self

Gojo’s acknowledgment completes Kaze’s long-standing plan to become a Heroic Spirit capable of answering his own summons 8 196.

• Rank A Clairvoyance: Arises from later generations remembering him as “the man who could see the future” 196.
• Future-self perception: Lets him see his future Heroic Spirit self 196.
• “The strongest in jujutsu”: Becomes an ability granting an innate, absolute advantage over jujutsu sorcerers 196.
• World-pillar status: Makes him an irreplaceable pillar of the Jujutsu Kaisen world 196.

Equipment / Weapons / Items

• Jewel Sword — His regular sword; accelerates cursed-energy recovery. He also disguises it with a projected Excalibur illusion when threatening the higher-ups 3 18.
• Black Keys — Summoned cursed tools with enhancement effects. Gives Maki the strength-boosting red and speed-boosting green versions while retaining the blue version, which increases cursed-energy output 19.
• Rin’s Pendant — Ruby necklace that increases critical damage against weak points 3.
• Book of False Vassals — Provides mental resistance 3.
• Dragon Vein — Provides continuous cursed-energy recovery 3.
• Magecraft Ore, Rune Stones, and Mapo Tofu — Consumables for cursed-energy recovery, resistance, and stamina respectively 3.
• Hello Lion Plush — Crushes it to restore health to himself and Inumaki during a mission 33.
• Gilgamesh’s clay tablet — Gojo offers it in exchange for Kaze calling him “Dad,” a bargain Kaze immediately accepts 39.
• Chains of Heaven / Enkidu — Sentient Divine Construct that floats around his wrist and waist without adding weight. Independently intercepts attacks and can destroy Sukuna’s Fingers 140.
• Vision — Focus for his Geo-based shielding, detection, and spatial-containment techniques 35 169 172.
• Nintendo Switch — Takes it along while packing for an urgent mission; Uraume later attempts to use a Switch as leverage during an escape 29 160.

Relationships

• Satoru Gojo — Teacher, protector, and genuine friend. Their relationship includes relentless teasing and “Dad” jokes, but Gojo’s support helps Kaze challenge the higher-ups. His final acknowledgment enables Kaze’s transformation into a world pillar 24 39 129 150 196.
• Megumi Fushiguro — Accepted older brother and Kaze’s closest family bond. They initially argue over seniority; Megumi later assists his treatment and confronts him over risking his life against Sukuna 53 75 86 145 180.
• Tsumiki Fushiguro — Megumi’s sister, whom Kaze considers “half a family member.” He appreciates her kindness but challenges her overly gentle approach to danger 42 145.
• Toji Fushiguro — Father within Kaze’s constructed identity, not his actual origin. Kaze rejects the relationship, seeks justice for the woman Toji abandoned, and refuses to let him burden Megumi with supporting him 145 146 147.
• Suguru Geto — Co-conspirator and collaborator. Kaze challenges his pride, works with him on secret plans, and proposes a spirit-power development path for his subdued curses 23 53 118.
• Yuta Okkotsu — Classmate and training peer who wants to help with Kaze’s behind-the-scenes plans. Kaze initially hesitates to involve him in the danger 18 98 99.
• Maki Zenin — Classmate and combat trainer. They share experience of obstructed advancement; Kaze supplies her weapons, while his nullification accidentally reveals the potential of her fully realized Heavenly Restriction 19 86 98.
• Toge Inumaki — Classmate whose friendship with Kaze strengthens markedly after a shared mission. Kaze later delivers upgraded Doggie models to him 35 196.
• Panda — Classmate and favorite cuddling companion. Kaze asks him to accompany Megumi on missions; Panda mistakenly believes a synchronization exercise is a suicide attempt 18 75.
• Shoko Ieiri — Healing instructor who successfully teaches him Reverse Cursed Technique and proudly plans to demonstrate her teaching achievement 68.
• Sakura Oogami and her parents — Neighbors whose support gives Kaze a place to rest. Sakura’s determination to protect others helps redirect his ambitions toward a safer future for young sorcerers 2 104.
• Junpei Yoshino — Younger acquaintance whom Kaze protects from bullies and helps toward attending Jujutsu High 79 84 87 90.
• Natsume Takashi — Friend whom Kaze heals and guides. Kaze recognizes that Natsume dislikes conflict and does not expect him to participate in dangerous plans 123 126.
• Enma Ai — Ally who promises to answer whenever Kaze asks for help after he encourages her to seize the Mountain God’s power 52.
• World Consciousness / Husky — Initially a transactional partner, later an adversary. Its concealment, manipulation, and restrictions on contact with his former loved ones drive Kaze to retaliate 14 129 144 161.
