Kara

is a mysterious organisation whose motive-of-operation is mostly unknown founded by Isshiki Ōtsutsuki. However, according to Koji Kashin, their agenda carries a sinister intent for the world at large, as they plot to cultivate a new God Tree huge enough to devour all life on Earth. Isshiki also states the Inners became affiliated with the organisation to fulfil their personal self-interests and collectively agreed they would acquire the God Tree's chakra fruit.

The group is made up of and, with each of the Inners being in charge of a particular region. Each Inner appears to bear a facial tattoo of a Roman numeral and wears a black hooded cloak with red lining, fastened at the right shoulder with a silver pin; all Inners are regarded as completely monstrous in power. Outers are people who assist Kara from the outside to complete missions requested by the Inners.

The Outers are responsible for significantly influencing the spread of Scientific Ninja Tools. As the Outers are engineers and scientists from various villages, they are able to significantly develop and improve the tools before bringing them back to Kara, leading to them possessing the latest in technology and engineering, which the organisation used to modify Kawaki.

The organisation has accumulated a great deal of wealth, makes use of Scientific Ninja Tools, and communicates over long range via genjutsu.

 * Delta, a woman with long, curly hair and prosthetic eyes. She has a tattoo of the Roman numeral Ⅰ in the centre of her forehead.
 * Boro, a giant, gregarious man with a beard and moustache. He had a trio of tattoos on his face that appear to form the Roman numeral Ⅲ. He was later killed by Boruto's Rasengan.
 * Victor, a short, stocky, elderly man with an eye-patch over his right eye and a prosthetic right leg. He had a tattoo of the Roman numeral Ⅴ on his left temple, and was known for his regeneration technique. He was burned to death by Koji Kashin.

Outers

 * Ao, a war veteran from Kirigakure. He was killed by Koji's Boiler Toad summon after pushing Boruto away from harm.
 * Garō, an associate of Delta who had prior interaction with Kawaki and was killed by him after a short fight.

Former Members

 * Koji Kashin, a genetic clone created from the DNA samples of Jiraiya, whose sole goal is to eliminate Isshiki. He was an Inner prior to his defection.
 * Amado, a genius scientist that served as Jigen's right hand and the head of the organisation's research and development division. He developed advanced Shinobi-Ware for Kara and is responsible for the creation of all its . Under Jigen, he was never granted leave, and is thought to know everything about the organisation. He has since formally defected to Konohagakure. He was an Inner prior to his defection.

Trivia

 * The kanji used for the two divisions of the organisation are and, respectively referring to the sanctum and the nave of a Heian-style Buddhist temple. When broken into individual kanji, they can be read literally as "inner team" and "outer team".
 * While not a member, Kawaki has a Roman numeral Ⅸ tattoo, which is located under his left eye.
 * Additionally, while viewed by Kara as just the vessel, Kawaki apparently held some access to Kara's information, as he noted that he had read Kara's files to learn about Tailed Beasts.
 * While Katasuke Tōno was never a direct member and was placed under genjutsu by a Kara agent, this made him act on the group's objectives which revolved around the development of scientific ninja tools and industrial espionage.
 * Until the advent of Boruto as Momoshiki Ōtsutsuki's vessel, Kara was pressed for time in their goal. Boro believes that Boruto's status has very well relaxed their time limit.
