The video discusses the Naruto technique "Kamui," a space-time Ninjutsu tied to the Mangekyo Sharingan. It is used by Obito and Kakashi, who have unique Mangekyo Sharingan that grant them access to the same ability. Kamui allows its users to teleport objects or people into a pocket dimension, known as the "Kami Dimension."
The technique has two variants, one for each eye. The left eye can project a long-range portal to the Kami Dimension, while the right eye creates a short-range portal. Both eyes can be used to teleport objects or people, but the right eye has the added ability to make the user's body intangible, allowing them to phase through solid objects.
The technique has several weaknesses, including a time limit for remaining intangible, the need to materialize to attack, and a situational weakness when fighting Kakashi. However, when both eyes are used in conjunction, they can create two portals to the Kami Dimension and connect them, allowing for more complex and powerful uses.
The video also discusses the chakra cost and risk of blindness associated with using Kamui, which seems to be mitigated in Obito's case due to his possession of Hashirama cells.
Here are the key facts extracted from the text:
1. Kamui is a space-time Ninjutsu tied to the Mangekyo Sharingan of Obito.
2. Kamui's name is rooted in Japanese folklore, specifically referring to the power and authority of the Shinto Gods.
3. The word "Kamui" literally means "authority of the Gods" in English.
4. Obito's Mangekyo Sharingan allows him to access an unnamed pocket dimension, typically referred to as the Kami Dimension.
5. The left eye can project a portal to the Kami Dimension forward into space, centered around the focal point of his vision.
6. The left eye can control the shape and size of the portals created and choose how long they remain tangible.
7. The portals created by the left eye act like a black hole, drawing everything near it towards its center and forcibly dragging targets into the Kami Dimension.
8. The left eye can teleport pieces of an opponent's body into the Kami Dimension, allowing for strategic advantages.
9. The right eye can create a portal to the Kami Dimension centered at its own position, allowing for short-range teleportation.
10. The right eye can eject people or objects that have been teleported into the Kami Dimension.
11. Obito can use his right eye to teleport himself into the Kami Dimension, making him intangible and allowing him to phase through solid matter.
12. Obito can only remain intangible for five minutes continuously with his right eye.
13. The right eye has a weakness in that Obito can only attack targets while he's materialized.
14. The right eye can teleport both himself and other people into the Kami Dimension, and can choose to eject himself at any point in the outside world.
15. The combination of both eyes working together can create two portals to the Kami Dimension and connect them, allowing for advanced space-time Ninjutsu techniques.
16. Synchronizing with another space-time dimension is very taxing on a user of Kamui, potentially sapping them of all their chakra.
17. Obito's repeated use of Kamui has had no negative impact on his eyesight.
18. Kakashi initially showed signs of fatigue after using Kamui, but was able to increase the amount of times he can use it per day through training.
