Nise Tengoku

is a Dōjutsu and Genjutsu accessed through both eyes of Kama Uchiha's Mangekyō Sharingan. It is a genjutsu of the highest calibre and it incorporates and synchronizes both Genjutsu used through Kama's eyes; Amenonaemasu and Amenowakahiko.

Usage
Using both eyes of his dōjutsu, Kama projects an illusion which is distinctively the same as reality itself. The target then experiences flashbacks about things that did not even happen. Kama manipulates the emotions of the user to be filled with penitence and stress, causing great depression until they die. Every single sense, including the ability to sense chakra, is hindered and, as a result, even those possessing dōjutsu will be manipulated to see and know what Kama desires. This illusion is cast by the target looking at anywhere the user has looked at, making evading next to impossible. Only those possessing the Rinnegan are capable of detecting the illusion, though there is no known way to release it beside the user releasing it. Any other entity or person that attempts to release the target will also find themselves trapped, making it extremely difficult to evade and impossible to release through help.

Drawbacks
This technique causes intense pain after use and causes both eyes to bleed. It also drains a lot of chakra and Kama cannot use it more than once a day.
