Ada

is a member of Kara.

Background
In his plot to kill Jigen, Amado heavily modified Ada, along with her younger brother Daemon with Shinobi-Ware with capabilities exceeding that of Jigen. The effects of her modifications left her forever despising Amado. Because of her superior might, Jigen had ordered for her disposal. Boro was given the order. However, affected by Ada's powers, Boro could not bring himself to complete the task, and instead hid Ada and Daemon in a remote location operated by his cult for his own uses.

Personality
Ada is a very cold and distant person. She cares little for the events around her. This comes from having grown bored in the life that was forced upon her. With all people automatically drawn to her, her greatest desire is to find someone who will genuinely love her. Ada showed great interest in Kawaki after he deceived Isshiki Ōtsutsuki, yet she also showed interest in Boruto Uzumaki seeing him as cute and dreamy. It was because of Amado who gave her the ability to be irresistibly attractive to everyone that she hates him, accusing him of taking away her ability to be genuinely loved, and she expressed her desire to kill him for it. Despite her desire to feel true love, in which both Kawaki and Boruto were potentially able to give her due to being partly Ōtsutsuki, she was, by her own claim, monogamous, and was fine if Code would sacrifice one of them to the Ten-Tails.

While unconcerned with others, she openly voices her disdain of combat, viewing it as barbaric. Despite her cold personality, Ada showed that she cares about the feelings of others. Witnessing the admiration that Kawaki showed for Naruto Uzumaki, she asked Code to spare him. He denied it, but still she understood that as Naruto was most responsible for Isshiki's death, Code would get revenge for his master, and instead just asked to keep her involvement in aiding Code from Kawaki.

When Ada witnessed Kawaki's willingness to put himself in danger to protect Naruto, Ada's admiration towards him increased, and when Kawaki demanded Code take him to Ada (while still unaware of her identity), the mere thought of Kawaki meeting her face-to-face was enough to make Ada's heartbeat to increase, as well making her blush. Also, when Ada witnessed Boruto refusing to abandon Kawaki and hearing his words of brotherly affection towards him, Ada expressed her amazement towards him, and her attraction towards him was increased considerably.

Appearance
Ada has long blue hair with loops on the tips and pink streaks, and two beauty marks under her blue eyes. She wears a white long-sleeved turtleneck shirt with bishop sleeves and dark shorts with patterns of blue stars and a moon, and a planet with a ring around it, blue earrings, and black high-heeled shinobi sandals with two blue crescent moons and blue heels. Ada also wears two blue bracelets on both of her wrists and matching rings on her ring finger and her pinky finger, and has pink nail polish on her fingernails and toe nails. When using the Senrigan, Ada's left eye sclera turns black and has a unique design with three dots.

Abilities
As with most members in Kara, Ada had been modified with Scientific Ninja Tools by Amado. While the true depths of her power is unknown, and she claims she can only use taijutsu, Amado has noted that her combat abilities exceed Jigen's. Ada has the power of clairvoyance, able to perceive everything that is currently happening in the world and all that has happened in the past, up to the point she was born. From her modifications, her very presence makes all who sees her, man or woman, with the exception of blood relatives and Ōtsutsuki, automatically infatuated with her to the point they cannot hurt her.

Code Arc
After the deaths of both Boro and Isshiki Ōtsutsuki, Code located Boro's hidden establishment managed by Bug. Bug stated he would lend Ada to Code if he was paid, where she was found in stasis. Upon awakening, she indifferently passed Code. Code initially subdued her, but found himself unable to strike her down despite her provocation. Ada merely stated she just wanted to freshen up before talking. After doing so, she and Code discussed her abilities. She also knew about Isshiki's demise and Code's goal of killing all those responsible. She assured him that only through Amado's cooperation, or at least the code word said in his voice and his modified iris scan, would they be able to remove the scientist's limiters on Code. It was also noted that with the Ōtsutsuki-modifications that both Boruto Uzumaki and Kawaki underwent from their respective Kāma, either would be a suitable offering to further the God Tree development, and one of them could potentially be the boyfriend she desired. Ultimately, Ada agreed to help Code use her visions to keep him ahead of the enemies.

Ada began revealing all the current events of Code's enemies through her Senrigan, she also revealed her limited skill set in actual combat. This made Code bring up the possibility that despite her interest in making Boruto or Kawaki her mate, there was still a chance they might try to kill her, since they were unaffected by her powers. Ada suggested they have Bug awaken her brother Daemon. Immediately, the boy showed his protectiveness to her, but Ada calmed him down by assuring him that Code was just a friend and not her type, to Daemon's surprise. Several guards of the hideout came to destroy them per their directives, who Daemon swiftly killed with his power to instantly reflect their attacks back on them. Later, as Daemon quickly began warming up to Code, he tried to get the boy to explain the full nature of his power. Before Daemon could answer, Ada forbade him, noting that it was too early to tell Code everything about them.

Later, as Daemon was sleeping soundly in Ada's lap, she used her Senrigan to detect that Kawaki was alone near the outside of Konohagakure. Code decided to take advantage of this opportunity. She continued to guide his movements until Code met with Kawaki. Her pleas for Code not to kill Kawaki woke Daemon up, but she told him to go back to sleep. Ada kept watching as Boruto joined them. She was pleased that Kawaki wanted to meet her, having deduced someone could convince Code not to seek vengeance on him, and was flustered by Boruto's dedication to protecting Kawaki.

When Boruto managed to unleash more power from his Kāma, Code asked Ada how Boruto still held his conscience, she suggested it was due to Amado's medications and ordered Code to make sure he didn't lose before regaining his full power. Ada kept watching as Boruto collapsed in pain. As she continued to watch the events, Momoshiki took control of Boruto again. As he pressured Code in battle, Ada advised him to retreat. When the situation became further complicated with Naruto and Shikamaru's arrival, she was surprised to see Kawaki absorbing jutsu with a new Kāma to protect Naruto from Momoshiki.

Ada explained that Amada secretly reapplied the Kāma while restoring Kawaki's right arm. She continued to watch the fight as Kawaki quickly made use of Isshiki's techniques to overwhelm Momoshiki, with the clear intention of killing the foe. As Kawaki was questions about his rash actions, he insisted that Momoshiki's resurfacing was too great a threat to ignore anymore. Boruto, having regained consciousness, agreed held Momoshiki's control down long enough to let Kawaki strike him down.

Trivia

 * Ada Lovelace was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first computer programmer.
