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 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 fourteen more children, Kawaki was the only survivor and became their vessel. At some point in time, Kawaki was placed in Amado's charge; however, the blimp carrying both Kawaki and the coordinates to Jigen's Ten-Tails was shot down, per Amado's plot to permit the former to escape and the latter to give Sasuke Uchiha a lead. Shortly afterwards, he was reassigned to another mission by Jigen, the details of which he refused to disclose to the other Inners of Kara.

At some point, Amado was given the research on Katasuke Tōno's Scientific Ninja Tools by Koji Kashin. Upon which, Amado began refining and expanding on the technology, incorporating it into the various Inners of Kara.

During his time within the organisation, Amado has gained complete knowledge of Kara and the Ōtsutsuki Clan. Because of this, Jigen has forbidden him to ever leave headquarters; to do so would amount to treason that could well result in Amado's execution.

Personality
Amado is a very stoic and detached individual. 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. 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 become 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.

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.

Appearance
Amado has white hair as well as a moustache and beard and thick glasses with orange lenses. He also is seen smoking. He wears a dark coloured 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.

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.

Intelligence
Amado is an exceptionally intelligent man with exceedingly advanced abilities in science and technology, with Kawaki describing him as a technological genius. He provided Jigen with the means to transfer his Kāma to multiple subjects through his scientific expertise, although it had a low level of success that killed many people until Kawaki successfully survived and received it. He also would extensively modify Kawaki down to the level of his circulatory and nervous systems, implanting inside him an extremely high level of Shinobi-Ware in the form of microscopic scientific ninja tools implanted throughout his entire body, with even the genius engineer Katasuke Tōno expressing 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. Delta also stated that Amado would be capable of restoring the arm he lost to her Destruction Beam. He also modified all members of Kara with fearsome Shinobi-Ware. Such modifications afforded him the opportunity to include shutdown commands into their shinobi-ware. He could also clone humans, as he created Koji Kashin, using Jiraiya's DNA.

While his true abilities remain unknown, in battle, Amado is shown to be a very methodical and knowledgeable man. Well-prepared, he skilfully uses a variety of technology to prevail, having devices such as a Scientific Ninja Tool able to emit powerful sonic waves that could repel and reverse the Shadow Imitation Technique, explosive collars that can be programmed or detonated with a command, and a drug capable of knocking people out that he administers through needles from his gloves, both of which he could seamlessly summon apparently from his hands even when immobilised. 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 against his father to get Konoha to listen to him, making it look convincing by detonating a genuinely explosive collar, which fooled Shikamaru and the others. He also came up with a plan to force Isshiki Ōtsutsuki to reincarnate in Jigen's body to remove Kawaki's Kāma by having Koji attack him when he was critically weakened from his victory over Naruto and Sasuke while deceiving Koji into believing he could defeat Isshiki even though he never intended for him to make it out alive, which even earned him Isshiki's praise.

Kawaki Arc
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.

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, as Jigen had only returned to 10% power, 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. 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 an escort and all his new 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, who was explained the situation by Amado. Kawaki's shock at losing his Kāma was quickly replaced by dread that Isshiki would come for him again and that no one can defeat him. Amado calmly reminded Kawaki that they don't have to directly defeat him, just wait him until his body finally breaks down, making sure that he doesn't brand Kawaki again during which. After it was realized that Boruto was fighting Isshiki alongside Naruto and Sasuke, Katasuke was worried about the boy. Amado noted that while he is no match directly for Isshiki, Boruto's usage against Isshiki is invaluable in another capacity.
