Kawaki (in Japanese: カワキ, Kawaki) is a major character in the Boruto: Naruto Next Generations anime and manga series. He is a part of the Kara organization and like Boruto Uzumaki he was given a powerful seal that grants him a lot of power. Years after meeting Boruto, Kawaki ends up destroying the Hidden Leaf Village reducing it to rubble.
He is voiced by Chris Niosi in the English dubbed version of the anime.
As a young child, Kawaki suffered domestic abuse by his father and as a result was stripped of his own childhood and became colder. When he met Jigen, he was also fearful of him and did not want anything to do with Kara.
When he first encountered Boruto and the other Leaf ninjas, Kawaki displays a defensive and menacing personality. He does not trust them and threatened to kill them if they did not leave him alone. He particularly distrusts for members of Kara who he sees as the enemy. In his battle against Garō, Kawaki is shown to have a cold-blooded streak as he did not mind murdering Garō to show that he is not to be taken lightly. With his curse mark like Boruto, Kawaki confess that he does not want anything to do with the Kara organization. He particularly resents Jigen for having violated his promises of a good life, as not only did Jigen coldly experimented on him, he also cruelly strengthened him, meaning he is unaware that Jigen seemingly regrets how harsh he treated Kawaki. Kawaki also seems to bond with Boruto over their shared fate of being hunted by Kara and seems to genuinely want him to work with him, even going as far as to be, even if only begrudgingly, steal a vase to replace the one he broke. Around people, Kawaki tends to show little interest with communicating with people and can be rude and disrespectful. Kawaki is shown to be anti-social but was willing to fix issues that he caused like fixing the vase he broke. However over time, Kawaki begins to warm up to Hokage's family and was willing to protect Naruto and his daughter, Himawari, from Delta's attack.
Years later, Kawaki shows that he is willing to destroy the entire Hidden Leaf Village to tell Boruto that the age of ninja is over. He also holds a level of animosity against the ninja world. Kawaki, however, did warn Boruto that if he fights him, he will send him to where he sent Naruto and Sasuke, although whether he killed them or just banished them to another location or possibly incapacitated them, implying over the years, the two had grown to have something of a friendship and Kawaki may not want to kill him. He is content in all the deaths and destruction he has caused in order to put an end to the ninja era.
As a child, Kawaki was raised by a single father who would constantly beat him up and demean him. Kawaki was found by Jigen when the latter met the abusive father to take him as his son. At some point, Kawaki woke up in a testing tube where he witnessed Jigen attempting to give a boy the kāma seal which caused the latter to die. Soon after, Jigen did the same to Kawaki but unlike the other boys, he survived. He later became the vessel for the Kara organization. After becoming a vessel, Kawaki was subjected to brutal fights with Jigen where the latter would beat Kawaki senselessly while putting him through pain from the kama seal. Kawaki tried to plea with Jigen to get rid of the kama seal but Jigen reminded him that it was a part of his identity. When Kawaki persists with getting rid of the seal, Jigen would become physically violent. Because of his treatment and the conditions of the kāma seal, Kawaki chose to escape from the Kara organization and wanted to find a way to get rid of the seal that Jigen gave to him.
Leaf Village's Mission against Kara
After dealing with Ao and meeting Kashin Koji, Boruto, Mitsuki, Sarada, Konohamaru, and Katasuke saw an unconscious and injured Kawaki near the site of a blimp that had crashed. Kawaki woke up in terror and with his uncontrollable powers let out a powerful energy that nearly injured or killed the Leaf ninjas near him. He gained his consciousness and confronted the ninja wanting to know what was going on. He threatened to kill them if they did not go away since he wanted to get away from the Kara organization. He took note of Boruto who seems to have the same marks as him before a member of Kara, Garō spotted him.
Kawaki confronts Garō and fights him. At first he was overwhelmed by Garo's power but his Kāma seal gave him more power. With his power, he was able to defeat and kill Garō. However, since he used a lot of energy he passed out from the move. Koji Kashin told Delta that he would allow the Leaf Ninja to take Kawaki away since he is confident that he would not give the ninjas important information.
First Days in the Leaf Village
Konohamaru's team brings Kawaki to the Hidden Leaf Village to make him recuperate from over-exhausting himself. Naruto tells Kawaki that he is here to watch him but Kawaki was not interested and tries to escape from him multiple times. Naruto firmly tells Kawaki that he is hear to watch him and that he is also here to protect the village. Kawaki was surprised at Naruto's power thinking that he could beat Jigen. Boruto came home to meet Kawaki as his new housemate. Boruto was angry that Kawaki broke Himawari's vase that she made for her mother Hinata. Kawaki apologies and introduces himself to the family.
Kawaki continued to stay at Naruto's house. he clashed with Boruto after fighting over the bathroom Naruto was using. He observed Nauto's family during dinner. He asked Boruto about how he got his kāma seal to which the latter says he got it from Momoshiki Ōtsutsuki. Kawaki then told Boruto about how he got his seal, his treatment afterwards, and how he wished that he could get rid of his seal. He wanted Boruto to help him since they both had the seal but Boruto rejected the offer since he was mad at Kawaki for breaking Himawari's vase. Kawaki resolved to replace the vase that he broke.
Kawaki walks down the street with Naruto and encounters Sarada. Kawaki gets into an argument with Sarada and a child accidentally runs into Kawaki. Kawaki uses his enhanced hand to scare the child but Naruto stops him from attacking the child. Kawaki tells the child to look out for danger and tells Naruto and Sarada that he was trying to warn the kids. Kawaki, Naruto, and Sarada gets to Ino's flower shop where he was to pick the vase. He is scolded by Sarada when he immediately picks a vase but Kawaki explains that the vase had a good design. When Ino tries to put the flowers into the vase, he got a vision of his traumatic mistreatment from Jigen and drops the vase on the floor breaking it. Naruto immediately comforts him and they got a new replacement. Sarada tells Kawaki that he if needs help, he can call her as she left but Kawaki was not impressed by her. Kawaki and Naruto made his way back to Naruto's house where Boruto gives him glue when he saw his vase.
Kawaki sits by when he heard about Naruto and Boruto planning for their sparring training. Kawaki and Himawari sits by and witnesses the fight and tells Boruto that he should activate the kama seal. Boruto activates it in his fight against Naruto but Boruto is defeated by Naruto. Kawaki asks what Naruto and Boruto's hand sign was and Himawari explains that it was the seal of reconciliation a way for ninjas to continue unity. Memory of Kawaki's abuse by Jigen resurfaces as he recalls a time where he was beaten mercilessly by Jigen during his training. Kawaki have a conversation with Naruto about ninjas, comradeship and the original purpose of chakra as a way of being able to connect with people. Kawaki decides to change a bit after the conversation and to glue the broken pieces of Himawari's vase back together. As he tries to put the pieces of the vase back together he loses is patience and interest. Boruto appears and tells him he wants to know about the seal he got, Kawaki suggest that they spar to get a better understanding of the seals. As they fight, Kawaki shoots an energy blast at Boruto to test his seal and the latter absorbs it. At the end of their sparring, Kawaki and Boruto did the seal of reconciliation but they felt a painful sensation from making contact with each other.
Moments later, Naruto tells Kawaki, Boruto, and Himawari to leave the training area as an enemy comes close to their location. Delta appears in front of everyone and reminds Kawaki about her punishments to him. Kawaki, Boruto, and Himawari, stand and watch Naruto fight against Delta. In his battle against Delta, Naruto tells her that Kawaki is considered his child and that he will not allow her to harm him. As Naruto's battle against Delta continues, Kawaki informs Boruto about the power of Delta's laser beam and how individuals with regenerative abilities cannot regenerate from the attack. Kawaki also reminds Boruto to not interfere in Naruto's fight against Delta since he has the upper-hand in the battle. However, when Naruto was about to get attacked by Delta's laser beam, Boruto attacks her with invisible rasengans which she absorbs. As a result, Delta attacks Boruto and attempts to kill Himawari by firing a laser beam at her after throwing her into the air. As Naruto was about to take the attack, Kawaki takes the laser beam causing him to lose a portion of his arm. Kawaki tells Boruto he is fine and that he could not allow the Seventh Hokage to get defeated. Kawaki tells Boruto that this makes them even after he broke Himawari's vase.
Delta yells at Kawaki for getting in the way of her attack by reminding him that he is Kara's vessel and that he specifically Jigen's vessel. Naruto continues to fight Delta and manages to overwhelm and defeat her. Kawaki along with Boruto and Himawari witness the conclusion of the battle. Delta lays at the bottom of the crater still alive from the attack. Naruto says that he wants to take her back to get information on her, but Kawaki tells him that she is too dangerous and that he should kill her. Before Naruto can retrieve her, she self-destructs in a large explosion. With everyone surprised at her suicide, Kawaki tells them that this how Kara deals with their situation.
Treatment and Training
After the battle with Delta, Kawaki was taken to the hospital to treat his arm. Unable to provide a prosthetic arm, Naruto opts to give him an arm that has his chakra to replace Kawaki's arm. Kawaki wants to know why Naruto helps him to which Naruto says he reminded him of himself when he was younger. Kawaki asks if Naruto can teach him ninjutsu and the Naruto agrees to help him.
Over time Kawaki trains with Naruto, fix up Himawari's broken vase, and socialize with other people in his village. Kawaki is close to fixing up the vase until he tries to find the last piece. As Kawaki tries to find the last piece, he walks up to a sleeping Naruto. Kurama's chakra emerges from Naruto and warns Kawaki that he should not get away from Naruto. Surprised by the Nine-tails, Kawaki wants to know what it is and it explains it's connection to Naruto and Naruto's upbringing in the Hidden Leaf Village. Kurama tells Kawaki that Naruto had a hard past for being hated by the village and was able to overcome his problem with his friends. Kawaki tears up realizing from Kurama that he has a some things in common with Naruto.
After training with Naruto, Kawaki is able to master the ability to walk on trees. He tells Naruto that he wants to eventually master the Shadow Clone Jutsu. Kawaki joins Naruto, Boruto, Sarada, and Mitsuki as they talk about the similarities between the Strength of a Hundred Seals (that Sakura Haruno and Tsunade have) and the Kama mark. Kawaki doubts there is a connection since the seals have a common shape, but the others are interested in the connection and wants to research it. Before Boruto and Kawaki leaves, Kawaki tells Boruto about taking down Jigen. Boruto calls Jigen his brother after their conversation and leaves.
Three Years Later
Kawaki destroyed the Hidden Leaf Village reducing the village to nothing but rubble. He proclaimed that Naruto and Sasuke have possibly been killed. He told Boruto that the age of ninja is over before clashing with him.
- Kawaki's name translates to "dry" in English.
