Crossing Over: From Three-Tail to Demon Slayer

A person is suddenly transported to the world of Naruto, only to face the night of their clan's destruction. As they prepare to unleash their full power, they realize that they have been transported to the Demon Slayer world once again. The location is the infamous Mt. Spider, and they find themselves facing a seemingly insurmountable challenge. With the Three-Tails sealed and the demon slayer, Giyu Tomioka, enraged, the protagonist must navigate this treacherous new world. Perhaps the main character in the original series, Uzui, will play a significant role in this new narrative.
