Code

is an Inner from the organisation Kara.

Personality
Code appears to have a mocking and arrogant demeanour, as he grinned when Jigen put Victor in place and mocked Delta for being weaker than him, being confident that either he or Boro could handle Naruto and thus assured one of them would be sent in to deal with the Hokage and retrieve Kawaki. In the anime, he laments at Koji killing Victor, wishing he could have done it.

Appearance
Code is a young, lanky adult with large green eyes and disheveled curly auburn hair. A black craniofacial prosthetic resembling a studded belt covers part of his scalp and face, crossing from above his right eye to under his left eye, partially hiding facial scars. He has the Roman numeral "Ⅵ" tattooed under his right eye and wears silver triangular earrings. He wears a black Kara cloak with lavender lining over a long-sleeved black shirt with a black waistcoat and white cravat, and black pants. The right half of his waistcoat and the ends of both pants and sleeves have a lined lavender section, and he has a silver pocket watch chain attached to his waistcoat. In the anime his eyes are instead purple, his facial prosthetic is silver, his earrings are lavender, and he doesn't wear the pocket watch chain.

Abilities
Being an Inner of Kara, Code is regarded as completely monstrous in terms of power, and has had his body modified with Scientific Ninja Tools by Amado. Describing himself as stronger than Delta, Code even seemed confident he or Boro would be sent in next after Delta was decisively defeated to retrieve Kawaki from Naruto. Kara also held his might in high enough regard that he was sent to guard the valuable Ten-Tails and when he was about to attack Jigen, Koji Kashin, another powerful Inner, showed caution at the possibility of either him or Boro being there to defend Jigen, suggesting his strength may be a match for Koji's.

New Era
At some point after the Chūnin Exams, Code looked into Naruto Uzumaki to determine whether or not Momoshiki Ōtsutsuki had marked him with his Kāma before being killed, but found no evidence of the mark on his body.

Kara Actuation Arc
In the anime, Code was present when Jigen called a meeting with the Inners, informing them of the destruction of one their facilities in Amegakure set by an Outer.

Ao Arc
Code attended a meeting held by Jigen to discuss the urgent situation relating to the missing "vessel". As Jigen dispelled the genjutsu, he voiced that they must recover the vessel at all costs. In the anime, he was called by Amado alongside the other Inners to have their bodies checked to detect anything suspicious regarding the traitor under the pretense of just being a maintenance; Amado also confirmed Victor's death, surprising Code. During which, Code found it interesting that Victor swore his efforts were sabotaged. He wondered if someone within Kara was after the Vessel now that it is in Phase 3. He also grew suspicious when Boro already knew about Victor's execution.

Later, Code silently eavesdropped on Jigen and Amado's conversation when the former confirmed nothing unusual was detected within them. Later, Code ambushed Jigen, who easily repelled his attacks. Code requested to deal with the traitor, which Jigen ignored, and reminded him of his assigned mission, much to Code's dismay. Afterwards, Delta taunted Code about Koji Kashin being on Jigen's good side, as well as Code's own need to impress him.

Growing impatient, Code decided to uncover the traitor himself, starting his interrogation with Delta since her number was "I". As he accused her, Delta countered that Code seemed the most pleased at the vessel's disappearance. Code was furious and primed to attack, only for Amado to arrive to calm things down. He revealed that the system check on everyone revealed no signs of treachery. Amado insisted that Code not act hasty or he could risk angering Jigen. However, as Boro and Koji had declined to go through it, Code was now suspicious of them.

Kawaki Arc
After Delta was defeated by Naruto Uzumaki, Code was present when she debriefed Jigen on her failed mission. He told her that she was too weak to face Naruto, and thus the task would fall to either himself or Boro. He was also surprised to learn that Momoshiki had left behind a Kāma after all, wondering if it was placed on Sasuke Uchiha before Delta revealed that Boruto Uzumaki was the one who received the mark. Later, while Jigen was recovering after the battle against Naruto and Sasuke, Code was with the Ten-Tails. He reported to Jigen, who informed him that there has been no contact from Boro in a while, and was instructed to keep a close watch, as Konohagakure had learned of the location.
