The Naruto franchise stands as a monumental pillar in the world of anime, captivating audiences across generations with its rich storytelling and a plethora of compelling characters, including a host of formidable villains. Among these, the Otsutsuki clan emerges as one of the most potent threats, characterized by their celestial origins and parasitic intent to drain the life energy from various worlds to sustain their evolution.
Introduced in the Naruto: Shippuden series, the Otsutsuki clan continues to be a central figure in the sequel series Boruto: Naruto Next Generations. Throughout their appearances, the sheer power displayed by these beings has inspired numerous fan theories on potential strategies to counter their overwhelming abilities. One particularly intriguing theory focuses on the Uchiha Clan and one of its most significant members.

Can Shisui’s Kotoamatsukami Counter the Otsutsuki?
The Uchiha clan is renowned for its mastery of visual jutsu, particularly the Sharingan, a dojutsu kekkei genkai granting unique abilities upon activation of the Mangekyo Sharingan. This clan boasts a rich history, with numerous powerful warriors, among whom Shisui Uchiha stands out for his extraordinary capabilities.
Shisui’s Mangekyo Sharingan ability, known as Kotoamatsukami, is particularly noteworthy. This technique allows its user to execute a subtle yet powerful mind-control genjutsu that influences individuals without their awareness. By infiltrating the thoughts of anyone within their line of vision, the user can craft phantom experiences, rendering the victim oblivious to the manipulations occurring in their mind. Kotoamatsukami is often regarded as one of the most formidable visual techniques, ranking alongside Tsukuyomi, Izanami, and Izanagi.

The potential of Kotoamatsukami as a counter to the Otsutsuki clan merits exploration. Given the nature of the Mangekyo Sharingan ability, one could speculate that such a mind-control technique might effectively subdue the Otsutsuki, restricting their mobility and ultimately diminishing their formidable powers.
It’s significant to note that, thus far, there has been no evidence suggesting that the Otsutsuki possess immunity to genjutsu techniques. However, this hypothesis remains largely untested, as no character has attempted to deploy genjutsu against an Otsutsuki in the anime.
When considering the limitations of other genjutsu techniques, such as Izanami, it becomes evident why this particular skill would struggle against the Otsutsuki. Izanami forces the target into an unending loop of pain until they concede to their fate, but the Otsutsuki’s self-awareness and acceptance of their destinies render this approach ineffective, as they lack the uncertainty required for such a technique to take hold.
Conclusion

The Otsutsuki clan first gained prominence during the Fourth Great Ninja War arc in the Naruto series, later becoming pivotal antagonists in Boruto. Known as descendants of the Byakugan’s legendary visual abilities, their power and influence remain a significant aspect of the series’ universe.
The speculation regarding the effectiveness of Kotoamatsukami against the Otsutsuki presents an intriguing scenario. While the theory holds weight based on the established powers within the series, it remains theoretical since Kotoamatsukami has yet to be utilized against an Otsutsuki. As the recent Boruto series concluded in 2023, fans continue to ponder the ultimate effectiveness of this Mangekyo Sharingan technique in combating such formidable adversaries.
