Amado Sanzu

is a former Inner from the organisation Kara and the head of its research and development division. He has since defected to Konohagakure, where he used a mix of bluffs and gifts to gain official citizenship for the Hokage's protection.

Background
Amado had a daughter who died twelve years prior to Isshiki's assault on Konoha.

In his quest to kill Isshiki Ōtsutsuki, Amado joined Kara and was granted the rank of Inner, serving as the head of its research and development division. He even created cyborgs that exceeded Jigen's power, Ada and Daemon, but the latter quickly ordered them to be eliminated. Amado imbued Ada with the ability to become irresistibly attractive to anyone except blood relatives or the Ōtsutsuki clan and imbued Daemon with the ability to instantly turn an opponent's attack against him. Ada's skill prevented Boro from getting rid of her and her brother as ordered, and Ada came to hate Amado for taking the ability to be genuinely loved from her. At some point after this, Amado came up with an alternate scheme against Isshiki when he acquired genetic information of Jiraiya, and used it to create a clone, Koji Kashin, who became his secret ally in their goal of killing Isshiki through his vessel in Jigen. During his time within the organisation, Amado has gained complete knowledge of Kara and the Ōtsutsuki Clan. Because of this, Jigen had forbidden him to ever leave headquarters; to do so would amount to treason that could well result in Amado's execution.

Amado would assist Jigen on transferring a Kāma into various children as their vessel. As the project continued to show no progress as one child after another died, Amado suggested they change methods for their goal, Jigen reminded him that they have neither the time nor a viable alternative. After they lost thirteen more children, Kawaki and Code were the only survivors, and though Code failed to become a vessel, he attained the White Kāma, while Kawaki successfully became their vessel. In the anime, Amado begun secretly microdosing Kawaki with a drug he developed to weaken the Byakugan, which resulted in this Kāma development being slowed down.

Despite the latter child's failure, Code's White Kāma granted him might well-beyond that of Jigen. While normally Amado would be required to destroy Code, his unique unwavering and fanatical devotion to Isshiki spared him from demise, instead having Amado place various limiters on Code.

In the anime, Amado witnessed a young Kawaki being confronted by Garō, where Kawaki unconsciously activated his Kāma and blasted Garō.

Personality
Amado is a very stoic and detached individual. He is very blunt with his views, willing to speak his mind despite what others think of him. He is a regular smoker (in the anime, he is seen enjoying a regular coffee). While speaking very respectfully, like Jigen, he appears to care little for the lives of others in pursuit of their goals. At the same time, he apparently prefers to not to sacrifice lives unnecessarily and is more realistic, as when a project shows no improvement after a certain period of time, he believes that it should be abandoned for an alternative one. He sees Delta's violent and destructive tendencies as annoying, berating her for needlessly kicking open the lid of her spare body's containment unit. He did, however, look at her solemnly and longingly when Jigen mentioned that every member of Kara's wish would be granted, suggesting he had some attachment for her. Very composed by nature, he has yet to let any situation make him lose his calm. Even when technically taken prisoner by Konohagakure, Amado remained undeterred, having established a variety of factors to maintain leverage in succeeding in his goals, showing a very methodical and intuitive nature. He is also very business-minded, as even while he apologised for his actions, holding Shikadai hostage with an explosive collar, unwilling to waste time or remove the collar before completing negotiations. At the same time, he is shown to be very manipulative, able to use simple baiting and mind games to accomplish his goals. Overall, he views himself as one who plays the odds, taking advantage of the situation to the best of his ability. To which, he openly admits he is not a man of indomitable will, truly believing he cannot endure torture well.

On the surface, like other members of Kara, Amado's loyalty to the organisation was due purely to self-interest, expecting to be granted something important for his services. However, this was apparently a façade as he conspired with Koji, intending to eliminate Jigen. In truth, his grand goal is to do away with the entire Ōtsutsuki Clan. Viewing their actions throughout history as vile and parasitically shameless, he even risked his life to defect to Konoha and offered all of his intel on Kara, Jigen, the Ōtsutsuki, and their Ten-Tails.

According to Isshiki, Amado looked up to Jiraiya as a man who bore mighty fate, and his desire to cling onto that fate was the reason he cloned the late Sannin to create Koji. Per Isshiki's declaration that all beings have their fates determined by their genes, Amado may also share this belief, hence his choice to create another Jiraiya.

Amado is also known to have a twisted sense of humour. One instance was when he joked about how killing Kawaki was one option to prevent Isshiki Ōtsutsuki from reviving, even though he already made sure that would not be necessary. He also smirked when Shikamaru demanded the bomb around Shikadai's neck be disarmed before revealing that it was a fake. In the anime, despite his dubious methods of joining Konoha, he openly feels indebted to the village for taking him in, quickly rejecting a lucrative bribe to defect to another village. He also acknowledges Konoha as it views science as a tool to promote growth, not a source of power. At the same time, he is still shown to be secretive and a schemer, having reapplied Isshiki's Kāma to Kawaki without approval of anyone.

Appearance
Amado has white hair as well as his beard, a trimmed moustache, and thick glasses with orange lenses, and light green eyes. He wears a black collared shirt and matching pants. Later, when travelling to Konoha, he would dress in a beige jacket with a green collar and pants and green sandals and gloves. Beneath his travel attire, Amado wears a green-coloured open collar shirt (black in the anime) and white pants. He also has a golden chain necklace around his neck. In the anime, after he receives his citizenship, Amado wears his intial black attire.

Abilities
As an Inner of Kara, Amado is described as having completely monstrous abilities. Amado is fast enough to easily close the distance between him and Shikadai Nara in an instant and bind him upon being freed from his paralysis. He can also use Yin Release to project an image of himself to talk with people from a distance.

Intelligence
Amado is an exceptionally intelligent man with exceedingly advanced knowledge in science and technology, with Kawaki describing him as a technological genius. Even Katasuke Tōno, Konoha's lead scientist and a recognised genius himself, openly acknowledged Amado's talents as well beyond his own. He single-handedly greatly augment the various abilities of the Inners and likewise can create cyborgs whose power exceeded Jigen. He provided Jigen with the means to improve the chances of candidate being compatible with Kāma. He could also clone humans. Using the DNA of Jiraiya, he created a perfect clone the legendary Sannin in his prime in Koji Kashin. He also created a drug that weakens the Byakugan in the hopes of defeating Isshiki, and was useful in stopping Momoshiki from reincarnating in Boruto's body. In the anime, his technological prowess was such that he could even revive the recently deceased.

While his true capabilities remain unknown, Amado is shown to be a very methodical and knowledgeable man. Well-prepared, he skilfully uses a variety of technology to prevail. He is also shown to be a proficient tactician and deceiver, planning several steps ahead, such as pretending to plant an explosive collar device on Shikadai to use him as a leverage to fool Shikamaru and Konoha. He also came up with a successful plan to force Isshiki Ōtsutsuki to reincarnate in Jigen's body and simultaneously remove Kawaki's Kāma, which even earned him Isshiki's praise.

Scientific Ninja Tools
As head of Kara's research and development division, Amado has been credited with the development of all of its fearsome Shinobi-ware and cyborgs. His technological genius directly resulted in the proliferation and advancement of scientific ninja tools far beyond the Scientific Ninja Weapons Team's combined capabilities, having been able to invent a number of uniquely powerful devices or expand upon those already distributed. He has also designed the organisation's autonomous puppets, used for fighting or otherwise simple tasks.

Each member of Kara was granted monstrous capabilities while outfitted with his technological advancements. Amado noted that he was even able to design cyborgs with capabilities that surpassed Jigen in terms of power, leading the latter to order their disposal. Among them were cyborgs that held unique abilities to perceive current and past events and to instantly reflect an opponent's attack. He also managed to modify Ada with the ability to infatuate those around her, protecting her from harm and submitting to her demands. Other powerful devices were implemented into Kara's cyborgs, including those that could heal virtually any injury, weapons that could counter an individual's regenerative abilities, and devices that could absorb, store, and release absorbed ninjutsu. He also developed a powerful virus capable of incapacitating those who are exposed to it. He was even able to modify Kawaki, Delta, and Code down to the circulatory and nervous systems, implanting an extremely high level of Shinobi-Ware in the form of microscopic scientific ninja tools throughout their entire bodies. Similarly, Amado was able to extensively augument Ao with Shinobi-ware, effectively rehabilitating him enough to engage in intense combat. Even the genius engineer, Katasuke Tōno, expressed awe at the level with which Amado had turned Kawaki into a living Scientific Ninja Tool and later noting that it was above his own level of expertise. Amado is also capable of restoring the arm Kawaki lost to Delta's Destruction Beam. Such modifications afforded him the opportunity to include power-limitters and shutdown commands into their shinobi-ware. Amado makes regular use of computers and tablets, using them to store the organisation's most vital information, monitor his teammates when operating on them, or check the status of his other scientific ninja tools.

Amado has revealed a number of tools that he can summon into his possession. Even when immobilised, he can programme them to activate with slight gestures. He makes use of devices such as explosive collars and a drug capable of instantly knocking people out that he administers through needles from his gloves. Against Shikadai, he used a tool shaped like a tuning fork to repel and nullify techniques that require concentration, such as the former's Shadow Imitation Technique. For espionage, he's developed tools that can be used to gather information, such as Delta's drone that can sense chakra, track invisible targets, and store information whilst being hidden from sensors. He can also modify and make use of animals. With similar modifications, he has been able to share their vision or project what they see, using his glasses. He also performed modifications on himself.

Ao Arc
In the anime, as Victor's body continued to deteriorate, he came to Amado for help. Despite Amado noting that his body would fail soon and could give him new body parts to extend his time, Victor bluntly refused being a lab rat again for Amado. Suddenly, Victor collapsed from a seizure. After Amado stabilised Victor, he was called for assistance by Delta, who voiced her annoyance that his work on her body didn't meet her standards. He was then contacted by Jigen, who wanted to discuss moving ahead with Phase 3 for the "Vessel" through a field test. While Amado was hesitant to agree, Victor appeared, offering to one of his new stealth blimps to help move the Vessel. Amado was wary, finding Victor's new cooperation very suspicious. As Victor said he was running out of time and needed the plan to be completed soon, Amado conceded to Victor's offer, on the grounds that he would have no direct part in the transportation. As apart of his plot to betray Isshiki, Amado had Koji shoot down the blimp, causing it to crash and allow Kawaki to escape, whilst also placing coordinates on the blimp to allow Konoha to discover Isshiki's Ten-Tails.

Later, with Jigen having doubts about Victor's claims that Deepa betrayed Kara by stealing its resources for his own agenda, Deepa's corpse was recovered and his brain was restored by Amado to get the truth, learning that it was Victor who betrayed the organisation. While performing a physical checkup on Jigen, the leader voiced his suspicions that a third party took advantage of Victor's betrayal to mask their own actions of causing the blimp to crash. Amado said he would investigate it. Later, Amado called all the other Inners to have their bodies checked to detect anything suspicious regarding the traitor under the pretense of just being a maintenance.

Later, as Delta prepared to test the maintenance work on her body, she was attacked by Code. He had 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. Delta however pointed out that Amado could have been using the situation to hide his own treachery. While Amado insisted he had nothing to gain from clearing the innocence of others if he really is the traitor, Delta remained wary of him.

Kawaki Arc
In the anime, after Jigen gave Delta permission, Amado questioned Jigen about letting Delta go check on the mission's progress herself only for the latter to respond that it didn't matter. Amado stated it could make it difficult if people were moving freely and had plans he needed to attend to. However, Jigen reminded Amado that it didn't matter and told him not to let anyone near him for a while which Amado complied and watched Jigen leave. Later, Amado asked Code to get Boro to come in for his maintenance check. While Code stubbornly said he wasn't allowed to leave the base without Jigen's permission, Amado assured him he would vouch for Code's actions, insisting that it would be of good aid to Jigen.

Amado checked on data from his desktop and noticed Delta's still intact drone's arrival at the Kara base. Once it connected to one of Delta body's terminals, he entered a few commands and watched her kicking open her containment in anger after she had awakened. Amado complained of Delta breaking the lid of the containment all the time, but he was told off by her that if he has time to complain, he should do his job. After Delta left, he commented on her mouth. Amado was later attending the meeting with the other Inners and he was informed that Boruto Uzumaki had his own genuine Kāma. In the anime, Amado informed Code about the scanning of Boro that he was also not the traitor.

Later, after Jigen defeated Naruto Uzumaki and Sasuke Uchiha in battle, sealing the former away, he returned to Kara's headquarters with his body breaking down. Jigen was hooked up by Amado to treat his body. The man voiced his disapproval of Jigen being so reckless with his body, noting that it would take at least two days to fully recover. Jigen voiced that he couldn't help but get excited after seeing how far and quickly Kawaki's Kāma was evolving and him synchronising with it. He theorised that it was because of his exposure to Boruto's own Kāma, also believing that Boruto was going through similar development. From this, Jigen strongly believed the two of them would become "perfect Ōtsutsuki" and form a God Tree to consume the planet. He also assured Amado that everyone would get what was promised, which left the bespectacled man looking away solemnly.

Later, when Jigen had not even regained 10% of his power yet, Koji returned. Knowing that Boro was safeguarding the sealed Hokage and Code was watching over the Ten-Tails, Amado realised that Koji would use this opportunity to kill Jigen. Deciding to make their move, Amado gathered the essential tools to continue his work, believing that he could complete the rest of his research with the scientific equipment that Konoha had in disposal. They were then approached by Delta, who realised their intention to kill Jigen. Before she could act, Amado activated a command to shut her down. Koji summoned a toad to transport Amado, and reverse summoned it to the outskirts of Konohagakure. He came across Team 10, who tried to apprehend him, but Amado made use of his tech to incapacitate them. He took Shikadai hostage, placing an explosive collar on him for leverage against the reinforcements sent by Ino, who Inojin managed to contact. He managed to get in contact with Shikamaru, and was pleased to know Naruto had been rescued, which he felt made his attempt to defect to Konoha more worthwhile. In exchange, he was willing to share his intel on Kara, Jigen, their Ten-Tails, and the Ōtsutsuki.

Amado was detained, where despite his claims of seeking asylum, was very bold while being interrogated. After Naruto gave his word as Hokage he would not go back on his deal, Amado began explaining all he knew. He revealed that how the Ōtsutsuki have since before recorded history been travelling from planet to planet, harvesting its chakra for the sake of evolving themselves while destroying the planet in the process, using the Ten-Tails for the process. He also revealed that Jigen himself was turned into an Ōtsutsuki from being branded by his Kāma of Isshiki. Amado also revealed to have sabotaged the blimp to free Kawaki and likewise ensure that Sasuke would get the intel of Isshiki. Amado's glasses then began beeping. His glasses were taken off, revealing a holographic projection of Jigen talking with Kashin. They learned that Kashin and Amado were working together so that Koji could kill Jigen.

As they watched Koji continue to reveal his true nature and intentions against Jigen, Amado continued revealing his secrets, on the grounds that Naruto formally accepted Amado's request to officially join Konohagakure with full amnesty and protection. He explained that Jigen was but an empty shell of his form self, fully controlled by Isshiki Ōtsutsuki. He revealed that Isshiki was once partners with Kaguya Ōtsutsuki, but there was a falling-out which left Isshiki mortally wounded. He found Jigen and made him his vessel. It was also revealed that the Kāma is a condensed recreation of an Ōtsutsuki, designed to help them cheat death by using the mark to resurrect themselves with the branded target becoming the new body. Insisting that neither Isshiki nor Momoshiki can be allowed to return to this world, he said he knew how to properly kill an Ōtsutsuki and would show them.

As the battle began tilting to Jigen's death, Sasuke wondered if Kawaki would be taken over, as Isshiki's remaining vessel. Kawaki rushed into the room and attacked Amado, but was blocked by Sasuke. Amado explained that upon death, those branded by Kāma are instantly turned into Ōtsutsuki, something even the Ōtsutsuki themselves have no control over. However, as Kawaki's Kāma hasn't finished extracting Isshiki's data, Isshiki can't resurrect through his body yet. When Koji killed Jigen, it forced Isshiki's resurrection on the imperfect vessel, which caused Kawaki's Kāma to disappear. Amado theorised this is a security feature of Kāma to avoid the creation of duplicates. This led everyone to realise that Isshiki has no Kāma left, and thus vulnerable to a permanent death. Soon after, the paperwork was completed. Amado was officially recognised as a citizen of Konohagakure and even allowed to work with the Scientific Ninja Weapons Team. However, he was not permitted to leave the village without two escorts of at least Shikamaru's ranking and all his available research would be available to Katasuke at any given time.

Upon accepting these terms, Amado revealed that the bomb around Shikadai was a fake. He also noted that now that Isshiki has resurrected in his imperfect state and would die within days, he would be more adamant than ever to ensure a proper vessel be made for him. This meant he would inevitably come seeking Kawaki. He urged the officials to evacuate the village before Isshiki arrived and to keep Kawaki near both Naruto and Sasuke at all times, making sure that Isshiki fails to rebrand Kawaki. Soon after, Isshiki indeed arrived in the village. Sai and Shikamaru were tasked with taking Kawaki away while Naruto and Sasuke faced Isshiki. Amado was told to join them in an underground facility. While hesitant due to Isshiki's Byakugan, he was assured that special preparations were made against the Byakugan. Later in the facility, Kawaki awoke, and had the situation explained to him by Amado. He also attempted to assuage Kawaki, explaining they didn't have to defeat Isshiki, only keep him from branding him until Jigen's body gave out. Kawaki was concerned for Boruto's safety when he learned he had also gone to fight Isshiki, but Amado again speculated that Boruto had his own key value in the fight.

Amado explained that Boruto, as a wielder of a Kāma, was invaluable to Isshiki. As the God Tree could only reach full maturity by sacrificing an Ōtsutsuki, once Boruto was fully transformed by his mark, Isshiki can sacrifice the genin instead of himself. Kawaki was furious at Amado's calm demeanour, demanding to know how much of this he planned for. Amado insisted that he only made the best choices available to him. As the Konoha-nin managed to calm Kawaki down, Amado offhandedly asked Kawaki if he is more furious at his powerlessness, or no longer having a purpose without his Kāma. Kawaki remained silent. As Amado was intrigued by Kawaki's prosthetic arm, he was impressed to learn that it ran on Naruto's chakra. As Amado noted he could easily restore Kawaki's arm, Kawaki noted through the prosthetic that Naruto's chakra was getting weaker. Amado was surprised when a rift took Kawaki away.

Later, while Amado was lost in thought on how to act next, word was received that Naruto and the others had returned safely and managed to defeat Isshiki. Amado responded flatly to it.

Chūnin Re-Examination Arc
In the anime, on the day of the Chūnin Exams finals, Amado was approached by a group of men at a train station. They quickly shoved Amado into a train car before it departed. In a warehouse, his abductors were revealed to be from the Land of Rivers that wanted to recruit Amado. They offered a very enticing deal, including lots of money. Amado however firmly rejected the offer, refusing to ally himself with people who only wanted his science for power. The men decided to take Amado by force. As Amado was about to make his move with his concealed tool, Boruto and Mitsuki arrived to save him, escaping the warehouse as it exploded in the fight. Amado indifferently thanked them, before reminding them that they had the finals to get to, to which they swiftly left.

Code Arc
Later, Amado was able to restore Kawaki's proper arm by cultivating it from Kawaki's cell samples. He considered asking Kawaki something but chose not to. Afterwards, he spoke with Naruto and Shikamaru about the remaining threats on Earth of the missing Ten-Tails seed and the last Inner, Code. He assured them there are other means for Space-Time travelling besides ninjutsu to find the seed and that the defeat of the last active Inner will cause all Outers to cease functioning. He also warned them of Code's tremendous might and limiters implanted on him, along with Code's fanatical devotion to Isshiki would make him seek out and kill all who were responsible for the Kara founder's demise. He flatly noted that if captured and tortured, Amado would not be able to resist removing the limiters. Taking to heart on Amado's warnings, Naruto requested Shikamaru to set up a Kage Summit.

After the meeting, Naruto approached Amado on how to handle Boruto's Kāma. Amado sympathised with the Hokage, having been a father himself years ago. He could tell that Naruto had yet to give up hope on saving his son. Amado gave Naruto a supply of pills that were designed to weaken the visual might of Byakugan users. He theorised that as the Hyūga had heritage from the Ōtsutsuki, it should help slow down or even suppress fully the advancement of the Kāma, but noted that it is still only a temporary solution. He also warned of potential side-effects from overusing these pills on Boruto. In the anime, proper dosage halted his Kāma progression, an in return Naruto allowed Amado to advise the entire Scientific Ninja Weapons Team.

Later, as Kawaki awoke following another checkup, having a nightmare about Code, proudly saying he was no longer a Vessel, Amado corrected him. He reminded Kawaki that even with the Kāma gone, his body remained partially modified into Isshiki's being. While Kawaki was angry at the statement, Amado revealed he already knew about Kawaki's idea of branding Code with a new Kāma based on Boruto to save Boruto's life. However, he reminded Kawaki that Code already had a different Kāma, so it might not work. At the same time, he noted that that with Kawaki's body already essentially housing Isshiki's body and Isshiki's spirit truly gone, Kawaki would have access to Isshiki's power without fear of being possessed by the man if Amado rebranded him. While Amado pointed out that Kawaki desired power to protect the Hokage and that Naruto, now void of Kurama's power, would probably lose against Code even with his limiters, Kawaki refused and stormed off. Afterwards, Sumire spoke up, asking why Amado was so insistent on rebranding Kawaki. As Amado noted that Sumire should have kept quiet if her goal was to spy on him, Sumire still asked what Amado's true goals were. Amado assured her that her fears were baseless and he truly intended to help the village. He also revealed that his newest project, a container near him, housed a powerful new ally for the village that he was working on with Katasuke.

Later, Amado reported to Shikamaru, who still voiced his lack of trust towards him. He assured Shikamaru that his manipulations never accounted for the most recent of events, openly surprised to see how close and loyal Kawaki has become to Naruto. When Shikamaru was notified that Kawaki had evaded surveillance to leave the village, he and Shikamaru wondered how and why Kawaki did it.

Sai reported that Kawaki was most likely fighting Code. Amado found it strange that Code found him so fast, knowing he had no sensory abilities. He considered Sumire's suggestion that he might have employed an Outer, but found it unlikely, not knowing any that skilled. He became lost in thought, ignoring Sai, and praying to himself for Kawaki not to ruin everything they managed to achieve so far, especially after he secretly reapplied Isshiki Kāma to Kawaki.
