Izanagi is a Genjutsu that is cast on the user instead of others and is the most powerful amongst this type of genjutsu.
When activated, the caster removes the boundaries between reality and illusion within their personal space. To a degree this allows the user to control their state of existence, but it is normally active for only the briefest of moments.
While the user remains physically real while fighting, this technique is capable of turning any occurrence including injuries and even death inflicted upon them while the technique is active into mere "illusions". Whenever the user receives a fatal injury, he or she automatically fades away as though they were an illusion all along and then returns back to reality; physically real and unscathed. The technique is based on an ability the Sage of the Six Paths had, referred to as "Creation of All Things"(万物創造, Banbutsu Sōzō). The process he used is explained to have initially involved the administration of imagination, and the spiritual energy which forms the basis of Yin chakra to create shape and form from nothingness. Then, through the application of vitality, and the physical energy which forms the basis of Yang chakra, he would breathe life into the prior form. Thus, a technique with the power to turn imagination into reality was born, known as Izanagi.
Izanagi can be used only by those with the genetic traits of the Sage of the Six Paths. The Uchiha, descended from the Sage, are able to perform Izanagi with their Sharingan. Even with such an eye acting as a medium, gaining the power to briefly control reality's flow as the user sees fit comes at a price; one has very limited reserves of time within a single eye for invoking this technique. This technique would normally be used for only the most dire of situations as after the Sharingan with which Izanagi was casted exceeds its limit, the said eye becomes powerless and is rendered blind permanently, with the rare exception that sight is restored to the eye if it further evolves into a Rinnegan. For this reason the Uchiha labelled it a Kinjutsu.
Danzō Shimura, in an effort to make practical use of the technique, had ten Sharingan embedded into his right arm. To use Izanagi to its full potential, users must also have the genetic traits of the Senju, who are also descended from the Sage. Partially for this reason Danzō had some of Hashirama Senju's DNA transplanted into his arm, which extended the time span of each Sharingan's Izanagi to a minute, allowing him to use the technique for up to ten minutes in total, with breaks in between as he deemed necessary. However, because Danzō is not an Uchiha, his chakra levels drop substantially every time a new Sharingan is used to activate the technique.Obito also makes use of Hashirama's DNA but, in contrast to Danzō, he claims to have gained control over Hashirama's DNA and as such, boasts the completed form of Izanagi.
As with many Sharingan-based techniques, the Izanagi can be implanted into one's Sharingan to trigger the technique even after the user has already died; Madara demonstrated such usage after his actual death, as opposed to merely negating a mortal wound.
Like the various techniques used with the Sharingan, this technique is named after a Shintō god. In this case, it is Izanagi, who, together with his sister and wife Izanami, created the islands and other deities of Japan.
One of the most famous stories about Izanagi tells the tale of how he goes into Yomi, the Japanese underworld, to retrieve Izanami after she died giving birth to the Shinto fire god Kagutsuchi. In Yomi, he manages to get Izanami and they both try to leave. However Izanagi was not supposed to look at her before they escape. Right before they reach the exit, Izanagi looks back and sees her in a decayed form. Frightened, Izanagi flees from Yomi and blocks the cave. Izanami curses Izanagi saying that she will kill 1000 people per day. In response, Izanagi says that 1500 people will be born each day.
After his failed attempt to get Izanami, he washes himself in a stream. As he cleans his left eye, Amaterasu is born, as he cleans his right eye, Tsukuyomi is born, and as he cleans his nose, Susanoo is born.
- In the past, Uchiha clan members used this technique during an important battle that they had to win at all costs. However, they soon started to abuse the abilities granted by this technique and as such Izanami was created as a way to punish the abusers of Izanagi.
