Ninja's are expected to always be loyal to the village and obey there rules and any mission given to them. Ninja's have for weapons "jutsu". To use a jutsu the ninja needs to use and manipulate their chakra. Also by using hand seals the jutsu is molded what the ninja is requesting. Specific jutsu's are Ninjutsu, Taijutsu, Genjutsu.
Chakra: Is a type of energy every living person has. The energy comes from both Physical and Spiritual. Chakra is essential for even the most basic jutsu. Chakra can be manipulated in different ways, mainly by performing hand seals. With chakra you can do basic things like walk on water, or make a shadow clone of yourself. Chakra is not normally visible to the human eye. But sometimes when a person release more chakra then usual their can be a image of the chakra, most chakra is colored blue (tailed beasts have a reddish type of chakra color). Their are two specific chakra stages or images (can't find a better word)
Chakra control- Its a term for controlling ones chakra and molding it how the user seems fit. Only the most skilled ninja can manipulate chakra the way they request. Some forms can vary one example is the rasengan which has a sphere shape, with great rotation speed.
Ninjutsu: Its a type of weapon used by a ninja for many purposes like Defense or Offense and Ninjutsu can even be used for healing someone. The effect's of a ninjutsu attack is real and can sometimes be life threatening. Ninjutsu vary is attack power by channeling more chakra or manipulating it. Ninjutsu, most of the time, relies on chakra and hand seals to be effective.When creating a ninjutsu, the two methods of manipulating chakra are referred to as shape transformation and nature transformation. Chakra shape manipulation and Chakra nature manipulation.
Elements: their are 5 basic Elements (lighting,water,fire,earth,wind). Elements are used in ninjutsu called Chakra nature transformation and its one of the two necessary tools of creating a ninjutsu. The five basic natures are all connected to each other in a circle, each being weaker than one and stronger than another.
Elemental Ninjutsu: Ninjutsu used with the 5 basic elements are usually nature transformation.Nature transformation is one of two necessary techniques for creating a technique. It is an advance form of chakra manipulation or control. It entails the moulding and defining of one's chakra into an innate type of chakra nature, giving it different properties and characteristics. Elements is the basis of Ninjutsu. All of the nature have weakness and strengths and this effects the ninjutsu as well for example... A water technique that is C-rank can easily put out a C-rank fire technique. But it would still lose to a C-rank earth technique. You can though use combine you chakra ninjutsu with elements that goes well with each other for example fire and lighting.
