{"id":"herramientas-cientificas-ninja","name":"Scientific ninja tools","japanese":"科学忍具","category":"science","subtitle":"Technique stored in a device.","summary":"A line of Konoha research that stores techniques and chakra in devices so any ninja can use them. Katasuke drives it in Boruto, opening a debate about effort and shortcuts.","facts":[["Aparece en","Boruto"],["Impulsor","Katasuke"],["Ejemplo","Kote"]],"lvl":2,"sections":[{"h":"Katasuke and Konoha's bet","t":"In Boruto's Konoha, the development of scientific ninja tools is in the hands of a team led by Katasuke. The idea is simple to explain and hard for veterans to accept: store complete techniques in a medium so that a ninja without talent or years of practice can release them in combat. Katasuke seeks political backing and sees Boruto, the Hokage's son, as the ideal face to promote his work. That is why he secretly offers him his prototype before the Chūnin Exams. The proposal is not villainous: the village already lives surrounded by trains, screens and phones, and the lab wants ninja technique to follow the same path.","lvl":2,"ch":"boruto-2","pos":702},{"h":"The Kote and its cartridges","t":"The best-known prototype is the Kote, a gauntlet loaded with small scrolls that serve as interchangeable cartridges. Each holds a technique another ninja sealed in advance, and the user only has to release it with a gesture, without hand signs or mastery of the chakra nature. Boruto uses it against the Mist triplets and against Shikadai, and Naruto discovers it in the middle of the final. The cartridges are single-use, so the number of techniques depends on how many are loaded. The article dedicated to the Kote tells the exam episode in more detail.","lvl":2,"ch":"boruto-4","pos":704},{"h":"The test against Momoshiki","t":"After Boruto's cheating, the exam ends with Momoshiki and Kinshiki Ōtsutsuki bursting in. To rescue Naruto, the Kage and Sasuke cross into another dimension equipped with scientific gauntlets, and there the limit no one had foreseen appears: Momoshiki absorbs ninjutsu, so every technique released from a scroll ends up feeding him. The episode does not entirely condemn the tool, but makes clear that storing others' techniques does not replace reading a fight. The final victory comes with a Rasengan Boruto did learn on his own, combined with his father's.","lvl":2,"ch":"boruto-9","pos":709},{"h":"Ryūtan, prosthetics and new weapons","t":"Research continues after the exam. Katasuke travels to the Ryūtan institute escorting the prototype of a prosthetic arm, and there Boruto meets Sumire again, who works as a researcher. The kids try out new equipment and, facing an enemy armed with technology, Team 7 builds its plan around a chakra katana. At this stage the series shifts its tone: Boruto no longer sees the tools as cheating, but as something that can be used well or badly depending on who wields it. He says so to Ao, the opponent who embodies the worst possible use.","lvl":2,"ch":"boruto-21","pos":721},{"h":"A prosthesis for Kawaki and Amado's contribution","t":"When Kawaki loses an arm protecting Himawari, Katasuke fits him with a prosthesis charged with Naruto's chakra. The implant works until Naruto disappears and Kawaki's body rejects it, a sign that these pieces depend on an outside source. The arrival of Amado, the scientist who defects from Kara, raises the level all at once: he restores a working arm to Kawaki, makes pills to slow Boruto's mark and works with the village under surveillance. Konoha gains a brilliant ally and, at the same time, a man whose motives no one fully knows.","lvl":2,"ch":"boruto-56","pos":756},{"h":"What the anime adds","t":"The Boruto anime expands this ground a great deal with its own material. It shows Ao and his views on the tools on the trip to Ryūtan, makes the lab the setting of several missions and adds inventions for the new generation: in the second Chūnin Exams, Denki beats Tsubaki with a suit full of ninja tools, and later the Funato pirates use an enormous technological cannon. These plots are exclusive to the animated adaptation and serve mainly to show how technology becomes an everyday part of the ninja trade.","lvl":2,"ep":"boruto-236","pos":758},{"h":"Science in Two Blue Vortex","t":"Three years later, technology is still at the center of the story. Amado remains in Konoha's service and, at Kawaki's request, agrees to unlock all his power; later, Kawaki enters battle with his limiters removed. Sumire, for her part, upgrades the sword Boruto uses. The line between ninja technique and laboratory is no longer debated as before: it is part of the arsenal the village uses against enemies who surpass any classic training.","lvl":3,"ch":"tbv-27","pos":807}],"characters":["katasuke","boruto","sumire","kawaki","amado","ao","denki"],"related":["kote","herramientas","cuerpos-modificados","kara","boruto-generacion"],"reference":"Boruto, manga, chapters 2–9, 16–22, 34, 44 and 56; anime, episodes 182–186, 226 and 236; Two Blue Vortex, chapters 18–27.","sources":[{"title":"Boruto: Naruto Next Generations · Índice de capítulos","url":"https://www.viz.com/shonenjump/chapters/boruto"},{"title":"Guía oficial de anime: Boruto","url":"https://naruto-official.com/en/anime"},{"title":"Boruto: familia y primeros pasos del Equipo 7","url":"https://naruto-official.com/en/news/01_1745"},{"title":"Boruto: Two Blue Vortex · Índice de capítulos","url":"https://www.viz.com/shonenjump/chapters/boruto-two-blue-vortex"}],"figures":[]}
