Ninja: A ninja is basically a soldier. They are trained to protect their respective villages and carry out missions. Each village has its own beliefs and ideals and as such each ninja from every village are different. ninjas are also the basic military force for each village and can or should rather act as ambassadors for theit villages
Chakra: This is the life force of ninjas, their energy source. Similar to an ordinary persons stamina, a ninjas chakra keep them going till it is almost exausted. With the chakra a ninja is able to perform techniques.
Ninjutsu: These are the techniques ninjas use chakra to perform. they can range from normal ninjutsu like clones to complex ones like Edo tensei; depending on the user's abilities.
Genjutsu: this deals with Illusions. But disturbing the opponents chakra flow, a skilled user is able to control and confuse the mind of his/her opponent by changing the way the see, hear, smell, or even think about things!
Taijutsu: Simple Taichi but on a higher scale. Taijutsu relies on strong physical attacks with the use of chakra. while seeming simple, taijutsu users can easily defeat certain Ninjutsu users and seem to have longer endurance.
Five elements: These are the basic elements on earth. Earth, Fire, Wind, Water and lightning. They are also the elements of the five nations and the five villages are named after objects relating to the elements: Leaves can be used to start a fire, mist is just water vapourised, Sand can easily be moved by wind, rocks are gotten from earth, and clouds produce lightning.
Five elemental releases: Each village has any element its high ranking shinobi can use very well. Elemental releases are difficult to learn and master, but most times can cancell out most normal ninjutsus. creating elements from chakra depends on how the ninja uses his/her chakra well: Increasing the temperature, slipting it into thin shapes, making it hard, vibrating, or turning it to liquid.
Cool! You got most of it right but i'll complete your knowledge with a set of definitions i myself made:
±± Ninja ±±
A ninja is someone who uses their full abilities in the service of his/hers beliefs, working to achieve a goal. This goal can be anything from peace to war, money, destruction, personal griefs or even revenge and can be shared with others or individual. Most ninjas are fighters and correspond to the bulk of the military force of the great nations. However, a ninja doesn't need to be a fighter. Even medics or a simple carpenter may, in times of need, use his abilities (medical knowledge or abilities in working with wood for example) to accomplish the goals he set to himself, following his beliefs.
±± Chakra ±±
Chakra is the energy that is formed through the passive combination of both the
Physical and the
Spiritual energies in a sentient being. Physical energy corresponds to the vitality of the body and its own energy. Spiritual energy corresponds to the mind or spirit, and comes from the awareness and "soul" of each sentient being.
Some ninjas have high levels of chakra because they have great physical energy (like the Akimichi or even Tsunade) and others because of their spiritual energy (like the Uchiha and the Yamanaka). However, its much more difficult to increase the spiritual energy than the physical one, thus why all ninjas pass through intensive physical workout.
±± Ninjutsu ±±
Ninjutsu, or Ninja Arts, is the ability to, through the use of chakra, accomplish tasks that would be otherwise impossible to do. Ninjutsu are done by molding the chakra and using it to produce the desired effect/technique. This is done by two basic principles:
Shape and
Nature Manipulations. These correspond to the two broad areas that one needs to change in the chakra to produce a jutsu. Shape manipulation pertains to the ability to give your chakra a desired form while Nature manipulation pertains to the ability to give your chakra a desired set of characteristics/properties. Sometimes, to better mold chakra, ninja use Handseals. Handseals are simply hand gestures that allow the ninja to more easily concentrate and mold the chakra into the desired technique.
±± Genjutsu ±±
Genjutsu, or Illusionary Arts, unlike ninjutsu, don't produce a real, palpable, feasible effect; it produces an illusionary effect. With a specific KG however, the illusions can become so strong that the body will be fooled into mimicking in real life the fake effects its perceiving through the illusion. There exists two types of Genjutsu: the passive, non chakra fueled ones (basically illusions to our senses like visual paradoxes and such which have little use in the RP and can be easily overcome through experience and logic) and the active, chakra fueled ones. Within the active chakra fueled ones two subtypes exist: Dojutsu fueled Genjutsu and Normal Genjutsu.
Genjutsu works by using chakra to disturb the chakra flow of the opponent, specially in the brain, altering his senses. By doing this you can make him perceive any thing his senses are capable of: pain, heat, cold, tickles, iching, etc etc. A ninja can make the opponent taste, smell, feel, see or hear anything he wants. However, because this is done by using your chakra to manipulate his chakra flow, the ninja needs to be close or, many times, have direct eye contact or even physical contact. This is the main limitation of Genjutsu: range. The further you are away from your opponent, the harder it is to induce the fluctuation on his chakra flow to produce the genjutsu.
How exactly does it work? Well, every one has a balanced chakra flow. The chakra flows in a balanced combination of both physical and spiritual energies. The ratio between them vary from person to person (that is how each person has a different chakra signature) but its always calm and balanced. To produce a genjutsu, a ninja uses his chakra to disturb that balance in a controlled way. A fluctuation is created in the persons chakra "wave length" and makes it fluctuate in a given way. This produces the illusion by scrambling the users link between his Spirit and his Body which effectively is the link between his mind and his senses. To make your chakra be capable of doing the correct fluctuation, you need to use, most of the times, handseals. These help you mold and shape and focus your chakra to the correct wave length you want to induce, thus enabling you to use it to disturb the targets chakra flow.
±± Taijutsu ±±
Taijutsu is basically Hand to Hand combat. Its composed of several disciplines and arts, the most used of which is called Strong Fist. Other types include for example, Gentle Fist. Taijutsu uses the body as a weapon to attack or defend against your enemy. Its powered by chakra but in a different way than Ninjutsu or Genjutsu, as you don't need to mold chakra to perform Taijutsu (as seen in Rock Lee's case). Chakra in Taijutsu acts as the fuel, powering the body through its moves, specially in terms of Physical energy. The main characteristic of Taijutsu is that it can be combined with several other areas of a ninja's arsenal, such as Kenjutsu or Ninjutsu (in this case producing Nintaijutsu). This makes Taijutsu the basic skill every ninja has to have.
Taijutsu can be advanced through mastery of the Eigh Inner Gates. These are "limiters" that exist within the chakra circulatory system and that regulate and limit the chakra output, keeping it at safe levels, thus keeping the body safe. Through intense training and skill, a ninja can unlock them gaining access to increased chakra output and, through that, increased physical power. However, doing so damages the body and may even lead to death.
±± Kenjutsu ±±
Kenjutsu or Sword Arts, are the skills regarding the use of swords in battle. Its in essence a more advanced variation of Taijutsu in which you use a bladed weapon (sword) to increase the letal capability of your attacks and to increase your defensive ability. Sword Arts vary greatly, perhaps even more than Taijutsu, and can, as the former, be combined with Ninjutsu or Taijtusu to increase its abilities and power.
±± Gogyo/Godai or The Five Natural Elements ±±
In Narutoverse exists 5 main energies in Nature: Fire (Hi), Earth (Tsuchi), Wind (Kaze), Water (Mizu) and Lightning (Raikou). Fire represents rebirth; destruction as a means for creation and emotions. Earth represents resilience, strength and durability; stability and bounds. Wind represents freedom, absence of regret and freedom of spirit. Water represents tranquility and peace; life and nurturing. Lightning represents wildness and boldness; its the element that embodies the desire to break free and to rebel.
±± Godai Seishitsu Henka or The Five Elemental Ninjutsu ±±
Elemental Ninjutsu correspond to the ability to manipulate or use the basic 5 elements for Nature through Ninjutsu, more specifically through Nature Manipulation. These correspond to 5 releases or styles: Earth Release (Doton), Fire Release (Katon), Water Release (Suiton), Lightning Release (Raiton) and Wind Release (Fuuton).
Each of these releases has a weakness and a strength towards another element:
-Fire Release is weak against Water Release and strong against Wind Release
-Wind Release is weak against Fire Release but strong against Lightning Release
-Lightning Release is weak against Wind Release but strong against Earth Release
-Earth Release is weak against Lightning Release but strong against Water Release
-Water Release is weak against Earth Release but strong against Fire Release
Now, we are here for Fire Release or Katon. Please, before we continue can you tell me anything more about Katon? For example, why is it weak against Suiton while in the other hand being strong against Fuuton? What is the main use of Katon Techniques in battle? ^^
