{"id":"herramientas","name":"Scientific ninja tools","japanese":"忍","category":"techniques","subtitle":"Origin, how it works and limits.","summary":"Boruto's technology, experiments and artificial resources.","facts":[["Procedencia","Boruto · Manga"],["Alcance","Original summary, not a universal repertoire"]],"lvl":2,"sections":[{"h":"Postwar technology","t":"Scientific ninja tools are devices developed after the war that store or reproduce techniques. In Konoha, the research team is led by Katasuke Tōno. His best-known invention is a gauntlet that stores techniques in scrolls and releases them with a trigger. Boruto uses it in secret in the Chūnin Exams and is disqualified for it. It is not a kekkei genkai: anyone can use the device, and that ease is exactly what unsettles traditional ninja.","lvl":2,"ch":"boruto-4","pos":704},{"h":"The gauntlet's limit","t":"Against Momoshiki, the limits of these tools show. The Ōtsutsuki absorbs the techniques coming out of the gauntlet as easily as if they were ordinary: the device does not change the nature of the chakra. Only Boruto, with a Rasengan of his own boosted by the Kage, manages to beat him. In the anime, Denki Kaminarimon, of Team 5, represents the useful side of this technology: he combines ninja training with technical knowledge. The lesson for Boruto is that a tool multiplies what you already know how to do, but does not replace training.","lvl":2,"ch":"boruto-8","pos":708},{"h":"Modified bodies","t":"Some tools are not loaded: they are implanted. Ao, a former Kirigakure shinobi, reappears with mechanical parts in his body, working for Kara. At the research institute he fights with a mechanical eye and arm that enhance his techniques. This line, modified bodies, is different from Katasuke's gauntlet: it cannot be removed and it changes the user. Kara uses this kind of body in its strongest members, and Konoha discovers that the enemy's technology is several steps ahead of its own.","lvl":2,"ch":"boruto-21","pos":721},{"h":"Kara and Amado","t":"Kara has more advanced technology than Konoha. Delta absorbs a Rasengan with her modified eye. Kawaki receives a prosthesis with Naruto's chakra, which comes loose when Jigen comes for him. Amado, Kara's scientist, created many of those bodies and, after defecting to Konoha, gives Kawaki an arm back. Amado modifies other people, but he is not the father of the beings he creates.","lvl":2,"ch":"boruto-56","pos":756},{"h":"Limiters and prices","t":"Amado also makes pills that help control the spread of Boruto's Kāma. The modifications have brakes: Code wears limiters, and when Amado removes them his power grows enormously. The cost of these enhancements is paid in the body of the one who receives them, and whoever controls the device or the code also holds power over the person. Rejection is a risk too: Kawaki's prosthesis ends up failing in his body before Amado solves the problem.","lvl":2,"ch":"boruto-70","pos":770},{"h":"In Two Blue Vortex","t":"After the time skip, Kawaki demands that Amado unlock all the power of his modified body, and Amado agrees. Sumire, who works in research, upgrades Boruto's sword. The technology is still in very few hands and every upgrade has a cost. Modified bodies are still in the fight too: Delta goes with Kawaki on his missions, and he himself faces Jura with his limiters released.","lvl":3,"ch":"tbv-27","pos":807}],"characters":["katasuke","amado","denki","delta","ao"],"related":["chakra","herramientas-cientificas-ninja","cuerpos-modificados"],"reference":"Reading guide for the series indicated.
