Kara

is a mysterious organisation whose motive-of-operation is mostly unknown. 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. Jigen 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. Their history is also currently unknown, but they appear to share mysterious ties with the ancient Ōtsutsuki Clan and its Kāma, including those borne by Boruto Uzumaki and Kawaki; the latter being very important to their leader Jigen as his future "vessel" and going to great lengths to retrieve him.

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.

 * Koji Kashin, a mysterious, masked man with ties to Konohagakure, who is Amado's one and only collaborator within Kara. Having no interest in his organisation's objective, his motive is to kill Jigen.
 * Code, a cocky young man with dishevelled hair and a craniofacial prosthetic who has the Roman numeral Ⅵ under his right eye.
 * 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.

Outers

 * Ao, a war veteran from Kirigakure. He was killed by Koji's Boiler Toad summon after pushing Boruto away from harm.

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.
 * In the seventh opening of Boruto: Naruto Next Generations anime, an eighth, as of yet unidentified, member was shown amongst the Inner members. This member has not been seen in the manga.
