Ada

is a former 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 indifferent 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 and unable to physically oppose her, she actually finds someone able to resist her at all amusing. Stemming from this, 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 although she deemed Boruto too young for her.

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 although she stated she wouldn't allow Code use Kawaki as the sacrifice for the Ten Tails. Ada also has a derisive attitude referring to Delta and Shikamaru as "dears" for not being able to attack her over her ability.

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. 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. She readily admitted she's only helping Code as a means of getting Kawaki as a boyfriend, blushing as she said it. However, she remains bashful at the prospect of actually interacting with Kawaki, and him being aware of her, becoming flustered when Shikamaru told him about her.

Ada's relationship with most people as strictly pragmatic and professional, as she did not condone Code's reckless actions of going against the enemies while using Daemon as a shield without her consent. She also threatened him with death if he failed to uphold his part of the bargain, rationalising it as a business transaction. She considered Code, constrained by his limiters, as useless to her, and that if he remains below her expectations even after removing said limiters, she would not hesitate in disposing of him. Even more, she has no problem changing loyalties should it suit her interests.

Appearance
Ada has long blue hair with loops on the tips and pink streaks, and a beauty mark under the outer corner of each eye. Her eyes are blue with uniquely having crescent moons wrapped around the dark irises that curve to the right. She wears a white long-sleeved turtleneck shirt with bishop sleeves and turquoise bracelets on her wrists and dark shorts with patterns of blue stars and a moon, and a planet with a ring around it, blue shooting star-shaped earrings, and black high-heeled sandals with two blue crescent moons and blue heels. Ada also wears matching rings on her ring finger and her pinky finger, and has pink nail polish on her fingernails and toe nails, and blue mascara. In the anime, Ada wears a small pair of blue bracelets.

When using the Senrigan, the sclera of Ada's left eye turns black with three dots and has a crescent moon design. In the anime, Ada's Senrigan has an expanded design: the sclera of her left eye turns galaxy-coloured and her iris turns bright blue with a dark crescent moon design, two white orbit-like dots at both side and the other big planet-like pupil on the centre.

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.

Being infused with the DNA from the remains of Shibai Ōtsutsuki, Ada gained the power of clairvoyance and is able to perceive everything that is currently happening in the world and all that has happened in the past, even events in different dimensions, up to the point she was born. However, her extrasensory perception doesn't extend to the spiritual and mental planes. The infusion also granted Ada the ability freely levitate and fly about as she pleases.

Due to Amado's unique modifications all who see her face are instantly by her − both men and women, with the exception of blood relatives and Ōtsutsuki − into becoming completely captivated with her. Her influence affects them on an instinctual, unconscious level, unable to harm her or resist her commands. Trying to resist her control for too long will lead to vertigo, fever, headaches, and inevitably lead to brain damage. However, non-offensive and indirect means of opposition, such as the Shadow Imitation Technique, are still possible. She has no control over this ability, and the effect lasts until she dies. Shikamaru acknowledges Ada could easily take over the entire world with this ability. Despite Amado's claims, Momoshiki, having determined the identity of the entrancing power, affirms this is not a shinjutsu derived from Shibai's DNA.

Code's Assault 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 speculated that Amado had no intention of letting Kawaki decide if he wanted a Kāma back, and believes he applied it when restoring Kawaki's right arm, knowing he'd crave power. She continued watching the fight between Kawaki and Momoshiki until Boruto emerged again, and agreeing with Kawaki's opinion of Momoshiki, pushed Naruto out of the way and allowed Kawaki to strike through his chest.

Code pondered about his options, and Ada warned him she wouldn't let him sacrifice Kawaki. Kawaki stopped Code from leaving and began overwhelming him. He warned Code that his ally was also a target of his as an enemy of Naruto, and prepared to kill him. Code pulled Daemon through the Claw Mark on his face, reflecting Kawaki's attack back at him, knocking him out, and sending Daemon back through. He confirmed that Kawaki was alive, Ada warning him she'd send Daemon to kill him otherwise. After his return, Ada pointed out Code had no Claw Marks in the middle of Konoha, where Amado, who Code wanted to remove his power limiters, was protected. He assured her he had already taken measures for it.

Ada reviewed the events after Code's retreat, and revealed Boruto's resurrection through Momoshiki's Kāma, though she was unable to determine what the communicated about. She was displeased with Code using Daemon without her permission, and reminding him of the terms of their agreement, threatened to kill him after his power limiters were lifted if he became a hindrance. He assured her he had already taken measures. When he emerged through a Claw Mark on Shikamaru to get to Amado, Ada complained the conversation he interrupted had just gotten interesting. After Code was pinned by a reprogrammed Delta, Code pulled her through into the lab, shocking Amado.

Amado was terrified by her presence, and Delta attempted to kick her, only for her to became infatuated with Ada. She ordered Delta to release Code, which she complied. Shikamaru paralysed her with his Shadow Imitation Technique, surprising her with actual, though non-harmful opposition. She commended him for his will power, and ordered him to release his jutsu, freeing her and Code. Shikamaru asked her goals, and she admitted she was only helping Code in exchange for getting Kawaki as a boyfriend. Shikamaru offered to join Konoha, offering another avenue for getting close to Kawaki, surprising her.

As she began to genuinely consider the offer, her Senrigan detected Kawaki's quick approach in the vents. Deciding to decline Shikamaru's offer, she and Code retreated into the Claw Mark, taking Amado with them. She also ordered Delta to handle Shikamaru as his technique still held her at bay. Before leaving, she thanked Shikamaru for the kind offer. Once returning to the base, Amado begged for his life in exchange for removing the power limiters. Ada watched as he did. Code moved to kill Amado, but he appealed to Ada's interest in Kawaki, which stayed Code. He reasoned that Code was now a hindrance to her, as Shikamaru's offer was an opportunity for her to develop a relationship with Kawaki. Unwilling to spare Amado in addition of Kawaki, he attacked, but Ada had Daemon stop him, reminding Code that she'd dispose of him if he remained a hindrance to her. She was grateful for releasing her, which she has repaid by restoring his full power, but has had enough of their partnership. Daemon maintained the upper hand when fighting Code, who retreated, telling her he'd return after becoming a proper Ōtsutsuki to see if he truly loved her, or if he'd want her dead. She was fine with him leaving as long as he didn't get in her way, reiterating she'd kill him if warranted. Amado explained how Kawaki was his ace, detailing his recent developments with the restored Kāma and Isshiki's abilities. She realised he also gave Kawaki something else, which he confirmed, explaining he implanted a shutdown command, meaning he's the only one who can keep Kawaki in check. She agreed when Daemon pointed out he could deal with Kawaki, and wondered if Konoha would be pleased if they killed Amado. He considered her point, but assured her his goal, which required Kawaki's Kāma was different, and suggested they go to Konoha, who he also had to explain his goal at length, promising to mediate for their alliance. She listened to Amado's phone call with Shikamaru, and criticised him for referring to her and Daemon as game pieces, barely containing her hatred for him over giving her her alluring ability, and threatening to kill him if he didn't help her with Kawaki.

On the train to Konoha, Ada spied on Shikamaru's mission briefing to Team 7, getting more flustered as she learned he was already setting her up to live with Kawaki, and informing him of her interest in him. Informing them of her clairvoyance, Shikamaru also addressed Ada, certain she was either watching or would watch the meeting later on. She hugged Daemon, elated at the prospect of getting what she wanted, finding Shikamaru's actions interesting.

Arriving in Konoha, she was welcomed by Shikamaru and Sai, her presence affecting everyone on the station. Having already learned about her living arrangements and refuse Sai's offer to accompany her, she flew off, carrying Daemon piggyback style. Upon landing on the house's balcony, she saw Team 7 watching her from afar. Inside, Konohamaru fainted upon meeting her, and Daemon knocked out both Boruto and Kawaki. When Boruto came to, she apologised for the harsh greeting, Daemon making it clear he's stronger than them. When Kawaki woke up, Ada blushed when he looked at her. Shikamaru contacted everyone through the comm system.

Amado explained the shinjutsu nature and origins of Ada's and Daemon's abilities, as well as his own goal of resurrecting his daughter. Still suspicious of Amado, Shikamaru asked Ada to confirm his claims regarding his daughter with her Senrigan. Finding it an awful attitude, but approving it, she confirmed that Akebi did exist and died 12 years prior. She noticed Boruto deep in thought, unaware that he was talking to Momoshiki's spirit. Shikamaru asked Ada what kind of person Akebi was, and she explained she was ordinary, completely unlike Delta. Feeling tired, she called it a day, agreeing to talk again the following day. The nex day, she answered Boruto that he was too young for her when he asked why she picked Kawaki instead of him. She became flustered when Kawaki asked her about her partnership with Code. When the boys began arguing, she asked Sumire and Sarada to join her, wishing to talk to girls. When Shikadai also stopped by, she sent him home. She told the girls how Kawaki made her feel, and Sumire asked exactly what about Kawaki she liked, though she was unable to give a concrete answer beyond his immunity to her ability. She asked Sarada about Boruto, and Sarada feigned being affected by her ability, causing her to resent it also robbing her of genuine friendships. Sarada asked to be her friend, surprising her. After Kawaki's departure following a commotion between him and Boruto, Ada decided to go out, asking the girls to join her. She warned Boruto not to restrict her freedom, and Shikamaru instructed him to accompany her. While shopping for clothes, she notified Shikamaru of Code's Claw Grime, detailing why he targeted the things Kawaki loves in retaliation for perceiving Kawaki as having stolen from him.

Later, when Naruto and Hinata suddenly disappeared, Ada discovered that Kawaki had sealed them away within a rift. Ada surmised from Kawaki's conversation previously with the married couple that Kawaki planned to kill Boruto again.

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 was often regarded as the first computer programmer.
