The video discusses the powerful genjutsu, Tsukuyomi, a Mangekyo Sharingan ability exclusive to Itachi Uchiha in the Naruto series. The name "Tsukuyomi" translates to "moon reader" and originates from Japanese folklore. The jutsu allows Itachi to create complex illusions, controlling both space and time perception, and can cause severe psychological trauma to the target.
To use Tsukuyomi, Itachi requires eye contact with the target, and the target cannot break free from the illusion once it is cast. The jutsu can even be fatal, as seen in the case of Azumi Uchiha. There are only two known counters to Tsukuyomi: cutting off one's eyesight, as demonstrated by Kabuto, or activating one's own Mangekyo Sharingan. However, the latter is only available to those with the Mangekyo Sharingan, and Itachi had already eliminated most potential users by wiping out the Uchiha clan.
The jutsu has a significant chakra cost and can deteriorate Itachi's vision over time. Despite this, Tsukuyomi remains one of the most powerful genjutsu in the Naruto series, with only a few jutsu, such as Amaterasu and Infinite Tsukuyomi, stated to be stronger.
