Ao's Gun

Ao wielding a scientific ninja tool.

Scientific Ninja Tools (科学忍具, Kagaku Ningu) are a product of Konohagakure's Scientific Ninja Weapons Team, leading to the village being viewed as specialists when it comes to this unique field of study.[1] Such inventions include weapons and tools for shinobi to use along with prosthetics and implants known as Shinobi-Ware. During the period of time Katasuke Tōno was being controlled, the technology was leaked to Kara.[2]

List of Scientific Ninja Tools

Scroll Cartridge

A Scroll Cartridge (巻物カートリッジ, Makimono Kātorijji) is a special type of scroll used as ammunition for certain scientific ninja tools. At first appearing as a normal sealing scroll, upon absorbing a technique it shrinks down to the size of a bullet and can then be loaded into a tool to be activated later. When a nature transformation technique is activated from a Scroll Cartridge, its elemental release is typically suffixed with "Bullet" (弾, Dan).

Shinobi Gauntlet

The Shinobi Gauntlet is a gauntlet developed by Katasuke that allows the user to quickly and easily activate techniques sealed in Scroll Cartridges.

Autonomous Puppets

Autonomous puppets, or automatons, are weapons that act independently without a puppeteer. They are used by Kirigakure[3] and Kara, the former of which can activate Scroll Cartridges to use Fire Release Bullet: "Blaze".

According to character trivia from Boruto: Naruto Next Generations:

  • The puppets' attributes are: 100 in strength, 10 in negotiation, 0※ in chakra, 30 in intelligence, 80 in perception, and 100 in dexterity. (※The Puppet Weapon's chakra is stored in and used from a condenser.)
    • They were also given a skill rating in these particular areas:
      • Mobilisation: ★★★☆☆
      • Marksmanship: ★★★☆☆
      • Wrestling: ★★★☆☆
    • Shinobi-Ware:
      • Fire Release Bullet (火遁弾, Katon Dan), Taijutsu Steel Nerves (体術鋼化神経, Taijutsu Kōka Shinkei), Armoured Model Rapid-Fire Shuriken Launcher (外装型連取手裏剣ランチャー, Gaisōgata Renshu Shuriken Ranchā), others

Smoke-Flash Bomb

Smoke-Flash Bomb is a weapon invented by the Scientific Ninja Weapons Team that has the ability to numb a person's senses with intense sound and light when their hearing and sight are exposed.


Shijima (シジマ, Literally meaning: Stillness) is a large device invented by the Scientific Ninja Weapons Team that negates sound by colliding specific phases of sound waves, the opposite principle of resonance. As it is large and currently negates all sound, its practical applications are limited.

Climbing mitts and boots

These climbing mitts and boots, which were invented by the Scientific Ninja Weapons Team, utilise Van der Waals forces in order to allow the wearer to climb and walk on walls without relying on chakra.

Kite Transport

This kite-like device, which was invented by the Scientific Ninja Weapons Team, is an invention that allows the user to fly, even though it's difficult to control.

Chakra Blade

The Chakra Blade (チャクラ刀, Chakuratō) is a bladeless katana invented by the Scientific Ninja Weapons Team that uses the wielder's chakra to create a Chakra Blade. As its chakra consumption rate is too high, it's not practical to use.

Powered Suit

The Powered Suit (パワースーツ, Pawā Sūtsu) was designed for nursing and rehabilitation care, but was modified by Katasuke for combat purposes, allowing its gauntlets to create orbs which absorb ninjutsu. The right gauntlet was stolen by Ao, while at the same time Boruto began wearing the left one.

Gatling Gun

The gatling gun that was supplied to Ao by Koji Kashin allowed the wielder to rapidly fire a barrage of Fire Release Bullet ninjutsu using Scroll Cartridges. It was destroyed by Konohamaru Sarutobi's Rasengan.

Foam Spray

The Foam Spray (泡スプレー, Awa Supurē) invented by the Scientific Ninja Weapons Team forms a film on an injured person's skin, sealing cuts and boosting their innate healing powers to heal wounds more quickly.

Mirror Drones

Remotely chakra-controlled drones that can be used to attack from high up in the sky.

Harōgakure's Ninja Tools

Hi and Mizu

Main article: Himizu (SNT) Himizu (火水) are a pair of Scientific Ninja Tool pistols owned by Nisshou Fuyutama and are individually called Hi (火) and Mizu (水). The pistols are unique in that they are used to fire pressurized "bullets" of chakra as its primary ammunition but in rare cases, Nisshou is able to use Chakra Flow to fire bullets made from his Sacred Flame Dance.


Arisa Rokuakari

Rokuakari (六明かり, six lights) is a flight system developed by Kurasa of Harōgakure's Research and Development. The device is seen consisting of a unique flight harness strapped on the users back which houses six miniature thrusters on it that then creates six light blue colored flame "Wings", The units are powered by Chakra batteries. There are only six currently in use in the Harōgakure Armada, the main two crew member users being used by Hiru and Arisa.

Unnamed Remote Drones

These are recon drones were created for the purpose of relying information both video and audio back to Harōgakure or its fleet. They are powered by batteries created from the chakra of the Six-Tails, and have no offensive capabilities. The use was inspired by records of the Six Paths of Pain and their linked vision.

Optical Camouflage

This is a device in which the shinobi is able to become invisible. The device is chest mounted and is powered by a small chakra battery. The unit works by projecting what is around the user to mask them from visual sight. The camouflage is not infallible as it doesnt mask heat or chakra, meaning sensors can detect the user.


  • According to Katasuke, Kawaki's body was modified with inorganic technologies to the point he can be considered a living scientific ninja tool.
