WARNING: The following contains major spoilers for Boruto: Naruto Next Generations #44, by Masashi Kishimoto, Mikio Ikemoto and Ukyo Kodachi, available in English from Viz Media.
In the Boruto manga, Konoha has struggled to gain leverage over Kara and its leader, Jigen. They’ve had soldiers infiltrating the Land of Fire and Jigen even managed to kidnap Naruto for a brief period while Kawaki and Boruto rescued the Hokage. Still, not even Sasuke has been able to figure out what the next plan of attack should be, which is very frightening since he’s already spotted Jigen’s alien form and a Ten Tails monster in storage.
However, Chapter #43 has finally given Naruto and Konoha their biggest weapon in the war on Kara, and it comes courtesy of a major defection: Jigen’s chief scientist, Amado.
The last chapter made the stunning revelation that Amado was working with Koji Kashin all along to bring Kara down from the inside. Here, Koji summons his teleporting frog and sends Amado to Konoha, but the scientist shows how powerful he really is before he departs. Delta tries to stop the duo, but Amado shuts her down with his voice command, which alerts Koji to how underestimated the doctor is. Even though they’re on the same side, Koji wonders if Amado has such shut-downs for all of Kara’s warriors –including himself.
When Amado gets to Konoha, all hell breaks loose, since he doesn’t know that Naruto has been rescued. On the outskirts, he attacks the kids and kidnaps Shikamaru’s son, Shikadai, hoping that could lure Naruto’s general out. The teenage shinobis try to fight back, but Amado already placed an explosive collar on Shikadai, and he’s wielding science tools that can neutralize jutsus — as seen when he warps Shikadai’s shadow paralysis jutsu. While this essentially makes Amado a one-man army, he doesn’t want to harm anyone. He just wants to defect but needs Shikamaru’s assurance he won’t be harmed.
Eventually, Amado mentally connects to Shikamaru and Naruto, and he expresses his apologies. He didn’t trust Konoha’s foot-soldiers, and he really wouldn’t have harmed the children. That said, he makes it clear what he’s bringing to the table — details on Jigen and how to take down his army. Amado engineered his soldiers, and that will give Naruto and Sasuke a much-needed advantage since they’re powerful enough to have shocked Konoha’s elite time and time again.
More so, Amado also knows the inner-workings of Jigen as he helped craft his body as a vessel for Isshiki Ōtsutsuki. Sasuke knows an Ōtsutsuki war is coming again, and he knows that he’ll need all the help he can get after fighting Kaguya. Amado can help provide insight on where this new Ten Tails came from and the Karma marks that make Kawaki Jigen’s vessel. His presence is a major benefit for Konoha’s science team too, since they could use some advancement in weaponry. Additionally, Kawaki will welcome Amado’s arrival, since his body is breaking down and Amado — the mastermind who helped engineer him — may well be the only one who can cure him. Ultimately, this looks to be a win-win for Naruto and Shikamaru, but there’s always a chance that Amado might not really be true to his word and could be working as a double agent for Jigen.
After Naruto and Sasuke struggled against Jigen and his terrorist cell, Boruto #44 just gave Konoha its biggest weapon yet in the war against Kara.
