Raised as a weapon, destined to become the body of a god. Sold to Jigen and then shaped by the Kara organization, Kawaki bears the Karma mark that makes him the vessel of Isshiki Otsutsuki. This profile follows his turning point: the weapon-child taken in by the Hokage's family, become the adopted son of Naruto and Hinata, and the ambiguous bond that ties him to Boruto, at once brother and rival. One of the darkest faces of the new generation.

Raised as a weapon, destined to become the body of a god, then taken in by the Hokage's family: Kawaki is one of the darkest and most important characters of the new generation. Here is his profile.

Contents

Kara's Weapon-Child

Kawaki grows up with an alcoholic, brutal father by the name of Kokatsu — a name spoken neither in the manga nor in the anime, and appearing only in the credits of episode 192. The manga shows Jigen, head of the criminal organization Kara, taking the child in and promising him that his suffering is over and that he is now his father (chapter 24, pages 15-19). The anime details the transaction: Jigen pays a large sum, Kokatsu accepts, and Kawaki, who refuses to leave, is knocked out with a bottle by his own father.

Next comes the ritual, described in chapter 27 (pages 18-32): fifteen candidates for the role of vessel are placed in artificial wombs connected by tubes to jars of fluid, through which Jigen attempts to transmit his Karma. The first thirteen die; Kawaki succeeds, on one of the last attempts. He is therefore not the group's only survivor, but the only success: Code, taken as a child as well, is the group's only failure to survive, and comes out of it bearing a white Karma. The anime adds that the ritual also targeted adults: Garo survived it at the cost of his arms (episode 188).

Under his left eye, Kawaki bears a tattoo to which no meaning is ascribed: the Roman numeral IX. The cover of chapter 1 in fact gave him a dagger shape in that spot — the idea of a "serial number" is interpretation, not source. Then come years of grueling training meant to make him Isshiki's perfect vessel, punctuated by blows whenever he asks a question and by reminders that he is worth nothing beyond his mark. He would later describe this period as a permanent hell.

In a dark room, a boy whose face is covered by a breathing mask connected to tubes floats curled up inside a translucent capsule; other capsules can be made out around him.
The fate reserved for Kara's test subjects: Kawaki was the only one of his group to escape it.

Isshiki's Karma Mark

The Kama — "Karma" in the Western translation — is not the tattooed seal it appears to be: it is better described as a pyramid-shaped barb embedded in the body, a compressed backup of the biological data of a member of the Otsutsuki clan. It gradually rewrites the bearer's genetic profile until it turns him into a perfect Otsutsuki; if the Otsutsuki dies in the meantime, his soul anchors itself to the vessel and eventually is reborn through him. The one belonging to Isshiki Otsutsuki sits in Kawaki's left palm, from which the marks spread over the left half of his body, glowing red — blue, in Boruto's case.

Jigen is himself only the body of a monk into which a dying Isshiki slipped to survive as a parasite before taking over his brain: an imperfect vessel, hence the search for a better host. Contact with Boruto changes the pace. The two marks resonate as soon as they are near each other, and both Isshiki and Amado see in this the reason why the two Karma are maturing faster than expected; Boruto's even activates on its own at times when Kawaki activates his.

The mark disappears all at once. Amado explains that a Karma automatically resurrects the Otsutsuki who placed it as soon as that Otsutsuki dies, without anyone, not even him, being able to prevent it: Jigen's death therefore forces Isshiki to be reborn in that dead, unsuitable body, and wipes out along the way every other Karma stemming from the same Otsutsuki. Kawaki's races for a moment, then goes out, leaving him unconscious. He had by then, it seems, extracted into his body about 80% of Isshiki's data.

The mark does not merely mark the skin: it gradually rewrites the body meant to host Isshiki.

Naruto's Adopted Son

Taken in by Konoha, Kawaki is housed with Naruto and Hinata. The beginning is rough: he tries to run away, breaks a vase given to the lady of the house as he flees, then has the replacement vase he brings back refused — Boruto hands him a tube of glue and sends him off to piece it back together. The visit to Ino Yamanaka, where Naruto took him to have the surroundings watched, goes badly: the dripping roots of the flowers remind him of Jigen's experiment, and Naruto defuses his panic attack by holding him close.

The taming happens through small details. Kawaki trades an extremely rare Fourth Hokage card for the Seventh's, hoping to learn more about Naruto. One night, while the Hokage sleeps, Kurama manifests his head to forbid him from wandering off, then corrects the false ideas he has about his host. Kawaki then discovers a childhood of loneliness and bullying very close to his own, and wonders whether he could become someone like him.

The word is spoken on the Hokage Rock, where Kawaki takes to looking out over the village while telling himself he has no place there, as Isshiki long drummed into him: Naruto brushes the objection aside and calls him his son. That same evening, he tries in vain to convince Himawari to use the vase he bought as a replacement: she keeps the one he glued back together, which in her eyes the repair makes even more precious. Boruto lends him his own forehead protector — he already wears Sasuke's — asking him to give it back the day he has earned his own.

Boruto's Brother and Rival

Boruto does not call him "brother" because the family told him to: he does it on his own, in support, the day Kawaki admits in front of their friends that it was Jigen who placed his Karma on him and that he will have to face him. The rivalry, for its part, is settled in training. The two boys bet that the winner of a duel will impose his method: Kawaki, who advocates the extreme confrontations he inherited from Jigen, tries to absorb a Lightning Release (Raiton) technique out of reflex even though he no longer has a mark, and the opening is enough for Boruto to win.

The series' opening shows the two boys older, facing each other on the destroyed Hokage Rock: Kawaki swears to defeat Boruto and declares that the era of the shinobi is over. The scene sits four years after the encounter with Konohamaru's team, whereas the present of Boruto: Two Blue Vortex takes place three years after that same encounter. It therefore remains one year ahead of the story: neither how it unfolds nor how it ends is established, and nothing in it points to a winner.

Three years later, the balance has flipped: Boruto puts Kawaki on the floor with a single punch and blames him for not having trained since they parted. Kawaki does not budge — every trace of Otsutsuki must disappear, himself included — but he ends up accepting an alliance against Code and the God Trees, warning that they will settle their own business once the threat is out.

Two teenagers side by side, leaning toward the camera and pulling faces, press their fists into each other's cheek: one with black hair in a blue vest and green T-shirt, a Konoha forehead protector around his neck, the other blond in a pink and black jacket, a Konoha headband tied around his forehead
The rivalry between the two adopted brothers plays out first in everyday life, long before the face-off announced by the flash-forward.

The Body Amado Built

Behind the phrase "body modified by implants," lies a precise setup: Amado has sown throughout Kawaki's body scientific ninja tools so small they are microscopic, and they constantly modify his tissues down to the cellular level, through his circulatory and nervous systems (chapter 25, pages 37-39). From them he draws abilities close to a kekkei genkai: hardening, softening, extending or turning his right arm into blades and tendons, producing growths that he detaches and throws as projectiles, or releasing a shock wave.

Katasuke Tono judges these modifications to be at least as advanced as the prosthetic he had designed for Naruto, if not more so, and draws the useful distinction: Mitsuki is a synthetic human produced by organic technology, whereas Kawaki is a natural human transformed by inorganic technology — a living scientific ninja tool, just like Kara's other cyborgs. The details of his equipment remain classified; his profile published in V-Jump sticks to a single line: nothing will be disclosed about the "Vessel".

His right forearm, destroyed by the beam of Delta, first receives a prototype designed for Naruto: it works only with the Hokage's chakra, which he must supply continuously in a negligible amount, and stops dead as soon as he falls asleep — it is by that signal that Kawaki guesses, from a distance, that Naruto is alive. The body eventually rejects the prosthetic, and Amado regrows an arm for him from his own cells. The scientist kept three safeguards for himself: a voice shutdown command that puts Kawaki into stasis — which Jigen had forbidden him to install — a camera in his right eye, and power limiters.

The Clone That Made Isshiki Lose

Stripped of his mark by Isshiki's forced resurrection, Kawaki is put in a safe underground facility. There he notices that the chakra feeding his prosthetic is weakening — meaning Naruto is in danger — when a rift sucks him in: the chakra link between the arm and the Hokage has just pulled him into Isshiki's dimension. Isshiki, who has only moments left to live in Jigen's body, uses the downed Hokage as bait. Kawaki shows himself, attacks with the ninjutsu Naruto taught him, is swept aside, then marked with a new Karma.

The mark vanishes at once. One rule makes the trick unbeatable: a Karma placed on a shadow clone disappears and does not transfer to the original — it was not Kawaki. Isshiki's time runs out, his body crumbles to dust, and Kawaki tramples the remains. The next scene costs him more: Boruto, taken over again by Momoshiki, stabs Sasuke's Rinnegan.

Momoshiki notes that Kawaki's body is already mostly Otsutsuki — the extraction had reached 80% — and decides to sacrifice him to grow a God Tree. Kawaki then sets himself ablaze, forcing the Otsutsuki to absorb the flames, which is enough to give Boruto back control. The two boys apologize to each other. Sasuke's Rinnegan and Kawaki's Karma have both disappeared: it is Boruto, the only mark-bearer, who will open the rift home.

The Karma Isshiki has just placed vanishes at once: a mark applied to a shadow clone disappears without ever transferring to the original.

Kokugan: The Black Eye and the Two Shinjutsu

Amado secretly restores Kawaki's Karma while rebuilding his right arm (chapter 59): with Isshiki's soul gone, the mark now works only as a weapon, with no risk of possession. It develops until it opens the Kokugan, an eight-spoked "black eye" — set in the left eye in Kawaki's case, whereas Isshiki wore it on the right. The number of visible spokes tracks his mastery: one at rest, two to five depending on the technique used, and all eight three years later, without even activating the Karma. This progression recalls the tomoe of the Sharingan.

The eye grants access to two shinjutsu. Sukunahikona instantly shrinks its user or any non-living matter in his field of vision, including energy and chakra substances, but never another living being; the change in size escapes the eye, to the point that the technique is often mistaken for teleportation. It was by this means that Isshiki, dying after the betrayal of Kaguya Otsutsuki, slipped into the body of the monk Jigen to survive there as a parasite.

Daikokuten stores what has been shrunk in a dimension where time does not flow: the object comes back out intact and so fast that it has outpaced Sasuke's Sharingan as well as a Naruto in Six Paths Sage Mode. Seeing these powers, Code concludes that the Karma has reached 100% extraction and that Kawaki has become a complete Otsutsuki (chapter 72, page 29). A publishing detail: introduced in the manga in July 2020, this dojutsu was not given its name until June 2024, in an entry of the official database.

The Day Kawaki Stabbed Boruto

A remark by Inojin about concealing chakra gives him the idea: Kawaki swaps places with a clone and leaves Konoha while erasing his signature, an Otsutsuki reflex he taught himself (chapter 61, pages 32-34). Outside, he offers to let Code kill him, in settlement of Isshiki's debt, on condition that he leave Konoha alone. Code finds the offer ridiculous, keeps beating him, and tells him he is no longer the target of his revenge: someone else wants to meet him.

Momoshiki then resurfaces in Boruto's body. When he decides to kill Naruto, Kawaki steps in, absorbs his Rasengan and discovers on that occasion that his mark has been given back to him; he stands up to the Otsutsuki (chapter 66). Naruto demands that he stop as soon as it becomes clear that he intends to kill Momoshiki, and therefore Boruto. It is Boruto himself who settles it: he restrains Momoshiki, tells Kawaki that he trusts him, and Kawaki runs him through the chest before the eyes of Shikamaru, who is left frozen by the scene.

What follows strings one break after another. Kawaki later admits he was disappointed at having failed to kill him, which earns him a slap from Hinata; he sends Naruto and her into the Daikokuten dimension through a rift, to keep them from intervening (chapter 77); he slashes the eye of Boruto, who had stepped in to protect Sarada, before Sasuke puts a blade to the back of his neck. He stated his rule himself: past a certain point, he believes he must act without attachment — and Boruto refuses to see cruelty in it.

"Kawaki Uzumaki": The Life Swap

Exhausted from overusing Sukunahikona while Konoha hunts him, Kawaki is found by Eida. When she holds him against her, her wish — that Boruto be a stranger instead of the Hokage's son — triggers Omnipotence, a shinjutsu inherited from the genes of Shibai Otsutsuki that the young woman does not consciously control. The memories of the entire planet are rewritten: Kawaki becomes the Seventh Hokage's son, Boruto the outsider taken in, and the world now calls him Kawaki Uzumaki.

He exploits the situation at once, forcing Eida to spread the word that Boruto killed Naruto, so that no one will stop him from cutting him down. For three years, the spell maintains its own coherence: it smothers the contradictions — a body modified by Kara in a boy supposedly born and raised in Konoha, the absence of Momoshiki — and makes those who are confronted with it even more stubborn in the face of visual proof. The very notion of Omnipotence is erased from the minds affected: revealing the manipulation does not hold, the knowledge fades away.

The exceptions are named. Sarada and Sumire were made immune by Eida's own desire for sincere friendship; Kashin Koji, who had awakened his own shinjutsu before the spell, saw Boruto's true place and the rewriting before it happened. Momoshiki, for his part, warns that killing the user would undo nothing. Amado, meanwhile, will end up recognizing his own modifications in Kawaki's body and deducing that his memory has been tampered with.

Eida's Omnipotence triggers on a planetary scale: the memories of the whole world are rewritten, and in them Kawaki becomes the Seventh Hokage's son.

Three Years Later: A Slider Between Offense and Defense

Three years after the swap, Kawaki flies, hunts Code's Claw Marks by shrinking them as they appear, and keeps watch on Boruto. Himawari calls him "big brother," which annoys him, and Mitsuki follows him relentlessly, to the point of knocking him out with a snake bite so as not to give away a surprise attack. It is Boruto who tells him the essential thing: Amado is capping his power by diverting it toward his regenerative abilities.

Kawaki immediately pins the scientist to the wall to demand his real power; Amado speaks his shutdown command and puts him to sleep. On waking, the deal is struck: Amado agrees to strengthen him against the human God Trees, on condition that Kawaki transfer his completed Karma into the cloned body of his daughter Akebi. Kawaki refuses until his offensive power is at maximum and every Otsutsuki threat has been eliminated, reserving the right to kill Akebi as well if she were reborn Otsutsuki.

The setting is a slider. At 100% defensive, Kawaki is almost impossible to kill and regenerates at full speed, but his striking power collapses; pushed toward the offensive, he holds his own against the human God Trees, at the cost of an overheating risk that catches up with him against Mamushi. Against Jura, he strikes from behind, bursts the leader's eye and impales him on black rods, before the latter regenerates and credits these surges of power to love. Amado will later reveal to him that he had set him only to 85% of his offensive power, and will fit him with an artificial toad to switch his settings remotely.
