Shinobi

"Shinobi are people who endure to achieve their goals… but depending on what they choose as their goal they change… like Madara and I…"

otherwise referred to as in the English translation of Naruto, are the primary focus and the main military power in the series. A female ninja is known as a. Most come from a hidden village, of which some come from specialised ninja clans, and will perform missions for a fee. These missions can include: doing manual labour, acting as escorts, gathering secret information, retrieving stolen items, carrying out assassinations, etc. In times of war, ninja will come together to defend their villages and land. The clearest characteristic of a shinobi is their ability to manipulate chakra to create and use techniques. Shinobi are expected to be loyal to their villages for life, and any defectors are considered to be missing-nin, and will be marked for death.

Jutsu
Shinobi can use a variety of techniques often based on the utilisation of chakra. This allows shinobi to perform extraordinary feats such as walking on water or walking up trees. Jutsu are separated into three groups, ninjutsu, genjutsu, and taijutsu. Ninjutsu implies performing a supernatural or beyond normal ability, the most common of which is the elemental jutsu. These are created by the user transforming their chakra into a specific nature or 'release'. The chakra types are Lightning, Earth, Fire, Wind, and Water. Other sub-types of chakra natures such as Wood Release and Ice Release also exist, created by combining two of the basic five releases. Taijutsu implies physical body techniques, which may or may not require chakra. Genjutsu manipulates the chakra in an enemy's mind and disrupts their chakra flow. Their senses get fooled which creates illusions, things that the foe believes to be real that are in fact fake.

Tools
Ninja tools are used as alternatives to jutsu. They can include weapons, accessories, and even clothing. Some ninja such as Tenten have mastered the use of such tools, but all ninja are able to use the most common to some degree. A standard shinobi will have a pouch equipped with many tools, and nearly every ninja is equipped with at least a shuriken holster. Most also possess and wear a forehead protector with the symbol of the village they derive from, though the ninja does not necessarily have to wear it over their forehead. The Inuzuka clan's ninken and Aburame clan's insects are also classified as tools.
