Jujutsu Kaisen and Naruto are both popular manga and anime series within the shonen genre, but they are not copies of each other. While they may share some common themes and elements typical of the shonen genre, such as supernatural abilities and intense battles, they have distinct storylines, characters, and settings.

While there's no denying that Jujutsu Kaisen and Naruto are two different franchises with completely different storylines and characters, both titles quickly rose to fame right after their debut.
