Dōjutsu

Doujutsu
This subcategory is not one of the main skill arts. This jutsu ability stems from the unique qualities of the users genetics. Doujutsu techniques involve jutsu ability found inherent in the eye that do not involve hand seals. Doujutsu techniques have several abilities. It gives one the ability to read Genjutsu, Taijutsu and Ninjutsu and then defeat it. It also gives one the ability to cast jutsu techniques only possible by possessing the eye. The primary users of Doujutsu are the Uchiha Clan, the holders of the Sharingan eye.

Amaterasu - Goddess of the Sun (Heavenly Illumination) Technique Amaterasu, named for the Goddess of the Sun, is a Ninjutsu techinque which uses the Mangekyou form of the Sharingan eye to create a mysterious black fire. This powerful fire can then be used to cut through a strong barrier and is said to burn for 7 days and 7 nights. Because of the amount of chakra needed to use the technique, it can only be used on a very limited basis daily. Also because it requires Mangekyou to use, not many individuals know of or can wield the technique.

Tsukuyomi - God of the Moon (Moon Reader) Technique Tsukuyomi, named for the God of the Moon, is a Doujutsu illusion technique which uses the Mangekyou (Kaleidoscope) ability of the Sharingan eye. This highly advanced technique can not be used extensively because of the toll it places on the user. To utilize the illusion, the clan member will look into the eyes of his opponent and cast a Genjutsu spell on them. The spell takes place in the mind of the one affected, while the jutsu is cast the one it was cast upon is at the total mercy of the clan member. The clan member has full control over space and time in the jutsu and can place the one affected through any hell they desire for any length desired. The technique itself only lasts for but a second in reality, but the one affected could have lasted through several days of pain. It is said only a natural born member of the Uchiha Clan can defeat it.

Mangekyou "Implosion" Technique - This doujutsu is a Ninjutsu technique which uses a form of the Mangekyou Sharingan eye to launch a long range attack. This technique may be a third Mangekyou skill in a trio named after mythological deities. The first is Amaterasu, next is Tsukuyomi and this may be Susanoo.

To begin Kakashi formed a handseal to change his normal three tomoe Sharingan into a new Mangekyou form. He then focused on an area of his target. The surrounding area then began to warp and collapse in on itself, quickly reducing the surround area to nothingness. The technique will thus essentially transport the focused area away to another location. The technique caused a huge strain on Kakashi, utilizing a great deal of chakra. He was able to use the technique twice in succession and then revert back to three tomoe, it is unknown how many times he could use it before total exertion
