During the fight between Boruto and Code, Kawaki discovered that he still possesses karma that was believed to have been lost after the death of Isshiki Ootsutsuki. This new seal implanted by Amado hides a secret revealed in Chapter 71 of the manga series.
Code and Eida escape Konoha’s lab by kidnapping Amado and return to their secret base of operations. This is where code forces the former Kara scientist to do it remove its limiters with the promise to set him free and not kill him. However, the heir of Isshiki does not keep his word and prepares to kill him.
Only thanks to him infinite resources, Amado teases Eida, who orders Code to release him. Code is now more powerful than ever and does not accept this imposition: Amado is one of those responsible for the death of his god and must pay for his actions. In Boruto 71, the Kara are destroyed from within.
After a bitter battle with Daemon, Code is forced to flee. Finally, Eida and the scientist can talk in peace. Amado reveals his intentions in Boruto 71. Apparently Amado not only implanted a new karma in Kawaki, but He also made sure he always had some way of controlling the boy should the worst happen. The power of the protΓ©gΓ© of Isshiki’s former ship is immense, no one in Konoha could do anything about it, but with a simple word from him, the karma would vanish instantly.
Amado has become a unique and essential resource for Konoha. He is the only one who can stop Kawaki in danger. The Leaf Village and all other ninja nations will inevitably have to rely on him. This raises concerns about what Amado wants to achieve in the future and what other mysterious mechanisms he has built into Kawaki’s body.
