A System in Naruto, but It's Jujutsu Kaisen?

Reincarnated into the Naruto world as Naruto Uzumaki, he finally awakens his system at age six—but something seems off. Why does it claim he has just enrolled in Jujutsu High? "Congratulations, Host! You have officially entered Jujutsu High—the Strongest Jujutsu Sorcerer System is now online." Naruto stares at the Ninja Academy gate, deeply confused. "Quest: Collect all of Sukuna's fingers!" "You mean this Nine-Tails inside me?" "Quest: Defeat Gojo Satoru." Naruto points at the white-haired, masked Kakashi, utterly baffled. "Isn't this system just plain stupid?" "Rewards: Ten Shadows Technique, Six Eyes, Limitless Cursed Technique, and Malevolent Shrine." "System, you're absolutely right! I really did transmigrate into the Jujutsu Kaisen world!" Years later, on the eve of the Fourth Great Ninja War, Naruto declares his victory: "We will win." "How boring, Obito Uchiha. I'll probably forget about you soon enough." "Madara Uchiha? You're the challenger." "Kaguya Ōtsutsuki? Just a mere mortal born in an age without me."
