Kawaki (カワキ, Kawaki) is the key to the fulfilment of Kara's greatest wish.[1]


During his childhood, Kawaki was raised solely by his father, a physically and emotionally abusive drunkard, until Jigen bought him with a large sum of money. Upon taking custody of the boy, Jigen told him that the suffering he endured was over and there was nothing to fear, as he was his new father.[2]

Jigen's Experiment

Kawaki being subjected to Jigen's experiment.

Some time afterwards, Jigen took him to a laboratory where he met Amado, telling him that he would give him a gift when they truly become parent and child.[3] Kawaki was one of fifteen children placed in artificial wombs connected by tubes to jars of fluid, through which Jigen attempted to transfer Kāma to them. The first thirteen children all died, however Jigen succeeded with Kawaki, one of his last attempts. Kawaki later awoke with a Kāma branded on his left hand. Despite Jigen's promise of safety, Kawaki would later describe his life from then on to be a living hell.[4] He would constantly be put through gruelling training, all so he'd master the Kāma as Jigen wanted. During it, he would constantly berate Kawaki as only having value as a vessel for the Kāma and would strike the boy whenever he questioned him.

Kawaki eventually also underwent extensive body modification, with microscopic technology being implanted into his body that constantly alters his physiology at the cellular level, granting him unique superhuman abilities similar to a kekkei genkai.[5] At some point he battled Garō, delivering a blow that tore off the man's lower jaw, for which he claims to have apologised.[6]


Stemming from his harsh childhood, Kawaki is shown to be highly aggressive and vulgar to people he dislikes or opposes. At the same time, he can remain calm and collected when questioning strangers, such as when Kawaki listened to Konohamaru Sarutobi's explanation about himself and his team. When not letting his temper get the best of him, Kawaki is shown to be very observant and problematic, easily reading the flow of battle before him and how best to react. Due to the massive suffering he has endured while forced to be a vessel of the Kara, which he described as being a living hell, he would gladly die than be stuck in said hell for the rest of his life. He has even shown signs of post-traumatic stress disorder, as simply seeing dripping roots of plants serves as a reminder of his struggles and has left him panting in horror. He appears to loathe himself for what he has become over the years he spent with Kara, stating that he would learn the Shadow Clone Technique so he could beat himself up to vent out.

Kawaki harbours deep resentment towards Kara, becoming highly alert and aggressive when facing off against members of the group. He particularly resents Jigen for what he deemed as a violation of his promises of safety, as shown by how he quickly erupted to a rage while unconscious upon being reminded of Jigen's adoption of him and later on when he showed clear resentment while describing Jigen's experiment. His anger towards Jigen is greater than his fear of him, as while initially greatly terrified when Jigen revealed he could come to him anytime he desired, he soon angrily denied Jigen as his father and attacked him while demanding to have Kāma removed, using the most vulgar expressions upon having his rage peaked. However, while appearing to be confident in his ability to defeat the Outers, he knows better than to believe than he could possibly come out on top against an Inner and has shown fear of them, as he has been seen to be afraid of Delta and Jigen, sweating in the presence of Delta and describing her and the other Inners as complete monsters, and expressing brief but great shock that Naruto could be more powerful than even his adopted father. Having seen Naruto's performance against Delta, who Jigen far outranks, Kawaki offered to go with him willingly, believing he'd kill Naruto otherwise.

Due to his harsh childhood, he is a stranger to simply joys like pastries, as he is openly amazed at their flavor. He is also constantly on guard, instinctively attacking a child for bumping into him without hesitation, although he claims he was only interested in scaring the child to show him the harshness of life.

Kawaki also seems to possess a dry sense of humour, as shown when Kawaki mocked Garō for his part in disfiguring his jaw in the past. He is also shown to be quite ruthless, fully capable off killing anyone who either opposes or angers him. In addition, Kawaki is also antisocial, showing little to no respect for others and being openly blunt and rude in his decision and opinion, although he does have some manners, as he is shown to be not above apologising when he does something wrong even if he initially believed it to be unnecessary, as shown by how he apologised, even if half-heartedly, on how he broke the flower vase Himawari gifted to Hinata after seeing how much it hurt her. In addition, he is not above fixing his mistakes if necessary, as although begrudgingly, Kawaki was willing to buy another vase to make Boruto agree to work with him. Over time, Kawaki came to appreciate his relationship with Naruto and his family, risking his life to save Himawari, although he insisted that it was for self-preservation on needing to keep the Hokage alive.

Over time with his new life in Konohagakure, Kawaki began opening up to others, apparently enjoying the game Extreme: Shinobi Picture Scrolls and showing an interest in learning ninjutsu. He became noticeably more responsible in tasks placed on him and relatively more calm and respectful. This change in nature largely came from Naruto, who would continuously show such patience and compassion to the boy. Also stemming this, Kawaki came to respect the Seventh Hokage, as he offered to trade an extremely rare Fourth Hokage card for a Seventh Hokage card, hoping to learn more about Naruto. Later, in learning about how he shared kinship with Naruto, both having such trouble childhoods yet Naruto was able to raise beyond it to find joy, Kawaki came to deeply admire Naruto and driven to learn from his example. Even more, he become infuriated with Jigen after the latter insulted Naruto, ordering him to never speak ill of Naruto. He also later came to respect Boruto, happy when Boruto openly considered him a brother. His newfound loyalty towards his surrogate family was even willing to sacrifice his freedom to ensure their survival.

Later, Kawaki apparently came to despise shinobi as he became driven to end its era once and for all.


Kawaki Anime

Kawaki during Konoha's destruction.

Kawaki is a young man with grey eyes and bushy black hair, the sides of which are shaven and blond in colour. As noted by Ino, despite his gruff demeanor, he is very handsome. Additionally, he has a tattoo of the Roman numeral Ⅸ under his left eye, a pair of piercings on his right eyebrow, and stud earrings. Kawaki wears a green shirt with a blue sleeveless vest jacket with grey stripe patterns on the collar and dark pants with a studded belt. He has a Kāma on the palm of his left hand in the shape of a diamond, which spreads across the left half of his face, chest, and arm, glowing red upon activation.[7] During the battle between Naruto and Delta, Kawaki lost his right forearm. It was temporarily replaced by an advanced prosthetic that was powered by Naruto's chakra.

Later on in his life, his right arm was apparently restored. He is seen wearing a violet infinity scarf and belt, white overalls with his chest exposed, and a black vest trench coat.


Kawaki's Explosion

Kawaki creating a shock wave.

Though Kawaki is not a ninja and does not know how to harness his chakra, he is still a remarkably powerful fighter, having been not only brutally trained in armed and unarmed combat by Jigen but also having extensive body modifications with a high level Shinobi Ware and mastered the power of Kāma from his training with Jigen. In the past he was able to destroy Garō's jaw and dozens of robotic puppets. Even in an exhausted state, his power was enough to repel Team Konohamaru and fend off Garō, easily defeating and killing him upon activating his Kāma, and would have killed Team Konohamaru with a single attack had Boruto not tapped into his own Kāma and absorbed it, with Delta openly praising Kawaki's might.

Since living Konohagakure and taking an interest in ninjutsu, he began learning it from the Seventh Hokage. This included chakra manipulation and shurikenjutsu, to which he showed a noticeable talent for, mastering the basics in a short period of time.


Kawaki possesses the Kāma mark, which he acquired after being the only one to survive Jigen's attempt to transfer his own Kāma. Due to his training under Jigen, Kawaki was already capable of activating the mark at will, although at times it does activate out of his control, and properly using it's power. He could absorb ninjutsu and create large-scale explosions with it active. However, using the mark causes his body to overheat, leaving him unconscious.

With the continued advancement of this mark, Kawaki has begun to subconsciously access a transformed state, manifesting a small horn on the left side of his head.

Body Modifications

Kawaki's body has undergone significant modification at the hands of an extremely talented scientist, down to the level of his circulatory and nervous systems, transforming him into something of a living scientific ninja tool. Upon initial examination, Katasuke Tōno deems the cybernetics in his body a work of art, as advanced as the prosthetic arm he designed for Naruto Uzumaki, if not more so. He also clarifies that unlike Mitsuki, who is a synthetic human that was genetically engineered using organic technology, Kawaki is a human being who was transformed into something else using inorganic technology.

Kawaki's Blast

Kawaki generating a blast with his modified arm.

His Shinobi-Ware takes the form of nanoscopic scientific ninja tools implanted throughout his entire body, which seem to be able to make particular alterations at the cellular level. For example, his body tissue can undergo rapid cellular division, causing it to expand, and it can also instantly undergo sclerosis or malacia to harden or soften. This allows him to partially transform his body in a manner similar to Jūgo's Sage Transformation, weaponizing it to produce sharp blades or piercing tendrils; these growths can even be shed, or thrown as projectiles. He can also produce a powerful shockwave from his body, repelling all around, even the ground below him.

Physical Prowess

Kawaki specialises in close-range combat. He is able to easily dodge Garō's blast and is shown to be very resilient, as he could continue fighting effectively despite his battered state. He is proficient in taijutsu, able to go toe-to-toe with Boruto in their fight. Kawaki is later shown to be proficient in using a , able to match Boruto's swordsmanship.

Kawaki Vs Garo

Kawaki fighting Garō.

Upon his body being discovered by Team 7, the shinobi discovered he had an identical mark to Boruto Uzumaki's. When both their seals began to hurt, Kawaki was dreaming of his first time meeting Jigen, leading to him abruptly waking up and destroying the area within his vicinity. Questioning who the team were, Konohamaru identified himself, and asked for information regarding the crash. Refusing to provide information and wanting to be left alone, Boruto revealed to Kawaki he also had Kāma, resulting in Kawaki believing they were pursuers from Kara. As they tried to correct him, Garō made his presence known, announcing his intentions of recovering Kawaki. Launching another attack, Kawaki dodged and began fighting while modifying his body, despite his weakened state. Upon Garō managing to subdue Kawaki, his Kāma activated and strengthened him, leading to Kawaki destroying Garō'a prosthetic arm. Walking towards Garō and absorbing his blast, Kawaki impales him with his modified arm, before killing the Outer with a shock wave.

To his surprise, Boruto instinctively activated his mark to absorb the shock wave and protect his team. This made Kawaki more convinced than ever that they were with Kara. Kawaki told Boruto to tell Jigen if he pursued him, the mountain of corpses would increase. Their conversation was cut short as smoke emerged from his body, leading to Kawaki collapsing and being examined by the shinobi. Ultimately, the Konona-nin decided to bring him back to Konohagakure to meet with the Seventh Hokage. When he awoke, he found himself in a hospital bed surrounded by the Konoha shinobi. Learning that he was in Konoha, Kawaki attempted to flee out of the room's window, but was restrained by Shikamaru Nara. Afterwards, Naruto introduced himself as the Hokage. Later, after an agreement between the five Kage, it was decided for Kawaki to remain unrestrained within Konoha while Naruto watched over him.

Kawaki & Uzumaki

Kawaki begins living with Naruto.

Naruto escorted Kawaki through the village to his house, during which he fled for not wanting to be used. To his shock, Naruto effortlessly caught up and blocked his path, prompting Kawaki to continue going to the Hokage's house. There, he attempt to flee again, but in the process destroyed a vase, leading to Naruto asserting his prowess and intimidating Kawaki into submission. When Boruto discovered Kawaki would be living with his family, he begrudgingly apologised before introducing himself. Later, after the frustrated boys fought each other, Kawaki revealed how he obtained his Kāma, and suggested they work together to remove their markings. Telling Boruto he'll replace the vase, Naruto took him to get a replacement. On their way, he met Sarada Uchiha, before arriving at Yamanaka Flowers. At the flower shop, Kawaki met Ino Yamanaka, to whom Naruto had entrusted to sense the enemies after him. There, he also had a panic attack after flower roots reminded him of Jigen's experiment. Seeing how traumatised Kawaki was, Naruto gave him a comforting hug, insisting that it was fine. Upon returning to the Uzumaki house with a new vase and flowers, Boruto rejected the new vase and instead gave him glue to repair the broken one, much to Kawaki's anger.

Boruto vs Kawaki

Kawaki training Boruto to use his Kāma.

Later, while watching Boruto and Naruto spar, Kawaki insisted Boruto try using Kāma, prompting him to activate his to activate Boruto's. The mutual respect and support between the two after the match concluded surprised Kawaki, remembering his own harsh experience with father-figures. Later, Naruto offered for Kawaki to try sparing with Boruto next time. Kawaki declined as he couldn't use chakra and though Naruto insisted that all can learn to do so as chakra exists in all people, Kawaki only stated he would like learning to use a shadow clone solely so he could beat himself up to feel better when frustrated. Knowing the feeling of having nothing and no one, Naruto insisted that self-hatred would solve nothing and that with friends, he could change for the better despite Kawaki believing it to be a complete lie. Afterwards, Kawaki bitterly decided to repair the broken vase. While struggling to fix the vase, Boruto decided to take Kawaki's offer of learning what he knows about their Kāma. Deciding to do so through sparring, the two quickly activated their respect marks. Kawaki then launched a blast at Naruto with the intent of him absorbing it like previously, only for Boruto to instead damage his hand. Naruto called off the match and told the two to perform the Seal of Reconciliation. The event made their marks react. While Boruto saw vision, Kawaki insisted he saw nothing when asked about it.

Kawaki Protects Naruto

Kawaki shielding Naruto and Himawari from Delta's attack.

As Naruto was alerted by Ino of an intruder, he informed the kids that an intruder was approaching them. The group was soon approached by Delta, who demanded Kawaki to be handed over. Informing Naruto that she was an Inner and how much of a threat she was, Naruto instructed Kawaki to protect himself while he engaged her in battle. Throughout the fight, Kawaki attempted to clam Boruto, explaining how Naruto was controlling the flow of the fight, leading it away from them by going on the defensive so he could go all out. Delta eventually unleashed eye beams that Kawaki noted to be designed to overcome regeneration abilities. When Delta attempted to use Himawari to get Naruto on the path of her eye beams, Kawaki shielded him from the beam, rationalising it as them being good as dead if Naruto had been hit, and considering him and Boruto even regarding Himawari's vase. While the battle continued, Naruto overcame Delta's absorption ability and immobilised her body with his Rasengan, before she self-destructed.

Following the battle, Kawaki was brought to Katasuke to repair his arm. When the scientist informed him that the technology in Kawaki's body was too advanced for him to handle, Naruto gave Kawaki one of his prosthetic arms that he powered with his chakra. Shocked at how sincere Naruto was at being nice, Kawaki asked to learn about ninjutsu, which Naruto agreed to and began training him. Proceeding this, Kawaki trained in ninjutsu and continued repairing the vase, as well as spent time with Boruto and his peers, during which he opened a Extreme: Shinobi Picture Scrolls and got a Fourth Hokage card, which he traded for Boruto's Seventh Hokage card. While Naruto slept and Kawaki discovered he was missing the last piece of the vase he constructed, Kurama manifested its head to warn Kawaki not to wander off from Naruto. While shocked, Kawaki remained composed enough for Kurama to explain its role in watching over him, and corrected certain misconceptions Kawaki had about Naruto, explaining the various hardships he had to overcome. Moved by it, Kawaki wondered if he could become someone like Naruto, which Kurama believed to be up to him.

Later, Kawaki impressed onlookers with his grasp over the basics of chakra control. When conversation turned to Kāma, he was initially dismissive of Sarada suggestion of a connection between it her mother's Strength of a Hundred Seal over their similar shapes. Mitsuki's claim that his parent was aware of the jutsu having a long and not fully understood history warranted further research. Kawaki admitted Jigen was the one responsible for giving him his Kāma, and that they would inevitably have to fight him. Boruto stood with Kawaki, even calling him his brother in support.

As Kawaki searched to no avail for the last piece of the vase, he eventually gave up and decided to stop the leaking parts with glue. However, his Kāma suddenly activated and opened a portal for Jigen to arrive, leaving Kawaki terrified and shocked at confronting him since his escape as he fearfully confirmed Jigen's identity and watched as he easily threw Naruto aside with increasing fear. He stood up to Jigen, but was effortlessly restrained as he demanded Jigen remove the seal from his arm and said he never recognise Jigen as his father. Jigen's disparaging of the Seventh Hokage enraged Kawaki and his Kāma activated, manifesting a horn from his head. As Naruto kicked Jigen away, Kawaki watched, still sweating, as Naruto and Jigen with their specific modes activated prepare to fight.

Knowing how powerful Jigen was, Kawaki immediately surrendered to him in exchange for him not harming the Seventh Hokage, reasoning that Jigen's power is on an entirely different level than Delta and he could potentially kill Naruto. Jigen agreed at first and asked Kawaki to come back cooperatively but Naruto made it clear he wouldn't stand by it despite Kawaki's protests so Jigen, much to Kawaki's horror, teleported Naruto and himself to another dimension, leaving Kawaki behind. Moments later, Sarada entered the house to inspect the damage and assess the situation. She found the melancholy Kawaki holding a picture of Naruto. When she asked Kawaki what had happened, his prosthetic arm suddenly snapped off, horrifying Kawaki as he realised Jigen had eliminated Naruto.


In the wake of Konoha's destruction three years after meeting Team Konohamaru, the two faced off on the destroyed Hokage Rock, where Kawaki vowed to defeat him and told Boruto that the shinobi era was over.
