Amado Sanzu

- Amado's initial appearance and after gaining citizenship to Konoha. - Amado's appearance after defecting to Konoha. 1/2 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.

Amado's daughter Akebi died of an unknown disease twelve years prior to Isshiki Ōtsutsuki's assault on Konoha. Despite this, Amado wasn't discouraged, believing he could resurrect Akebi by cloning her and transferring her memories into her into a new body by preserving her brain, rather than try to develop a cure for her disease. However, Amado's hopes were crushed as her daughter's clones, later named Delta, despite having the same appearance and memories as Akebi, were completely different individuals. Amado tried to recreate Akebi's personality multiple times, but failed to do so and finally broke down, realising his daughter was gone for good. It was then when Jigen approached Amado, promising to bring his daughter back to life if Amado aided him with his plans, Amado accepting it immediately. During his time in Kara, he became an Inner and served as the head of its research and development division, used Scientific Ninja Tools to augment the various members. He also analysed the remains of Shibai Ōtsutsuki, transplanting his DNA in an effort to imprint his abilities onto other Kara members, with random successes. Eventually, he learned a lot about the Ōtsutsuki clan, discovering Isshiki's true motive which would destroy all life on the planet, making Akebi's resurrection moot. He switched his focus to destroying Isshiki. He even created cyborgs that exceeded Jigen's power, Ada and Daemon, but the latter quickly ordered them to be eliminated. As Ada's enhancements made her become irresistibly attractive and Daemon's enhancements could instantly reflect threats, Boro vould not get rid of the siblings and instead had them sealed away. 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 Jigen. All the while, Amado didn't give up on resurrecting Akebi, having realised that Kāma resurrection was able to accomplish the restoration of personality he failed at. During his time within the organisation, Amado has gained vast and intimate 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 and instead attained the White Kāma, while Kawaki successfully became a proper vessel. Amado modified Kawaki extensively with Shinobi-Ware, but did not put in an emergency shutdown command, as Jigen forbade the latter on his precious vessel. In the anime, Amado began secretly microdosing Kawaki with a drug he developed to weaken the Byakugan, which resulted in his 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 Kawaki being confronted by Garō, where the young boy unconsciously activated his Kāma and blasted Garō. When his research on the human heart hit a dead end, he augmented Ōga's brain so she could aid him, but her attempt to study Jigen's heart was considered treason, and she fled after Jigen gave her brain damage.
