Chakra is the substance that signifies a Shinobi and what sets them apart from regular people. It acts as the life-force of a Shinobi, without which a Shinobi can die. It is also the medium through which a Shinobi performs their abilities, collectively known as Jutsu. Every Shinobi possesses a Chakra Nature, identifying which Jutsu they have an affinity for. These Natures can be either Fire, Water, Earth, Wind, or Lightning, and can be discerned using Chakra Paper. While a Shinobi's Primary Chakra Nature designates which Jutsu they will have the easiest time learning, this does not mean that they can only learn Jutsu from that one Nature. An experienced Shinobi can possess a Second or even Third Chakra Nature, allowing them to greatly expand upon their abilities.

Jutsu are a breed of supernatural technique utilized by Shinobi; these can be for combat or for utilitarian purposes such as high-speed movement. A Jutsu will expend a Shinobi's Chakra in an amount proportionate to the strength of the Jutsu. If a Shinobi tries to perform a Jutsu that expends more Chakra than the Shinobi has, the Jutsu will either not work or will be very weak. Each Jutsu has an assigned rank, based on their power. In ascending order, these ranks are E, D, C, B, A, and S. Shinobi use Hand Signs to perform these techniques, each of which has its own sequence of Hand Signs. There are around two million Jutsu in existence, with more being developed constantly. There are several different branches of Jutsu, such as Ninjutsu and Taijutsu.
