Naruto and Mito his twin sister (carbon copy of Kushina) after running from villagers are taken by their father Apollo to Percy Jackson world where they meet up with Silena who is on her way to camp after losing her father to a monster sent by Ares. Ares continues to send monsters after them to kill silena but Apollo begs Artemis to take her hunt and find his kids and bring them safely to camp she agrees and when they get to camp Artemis asks Mito and silena if they want to join Mito jumps at the opportunity (same reason as Bianca) while Silena says no. Naruto and Mitos relationship is destroyed he hates her and she wants him to not hate her but also understand why she joined.
Pairing NarutoxSilena
Mito has chakra chains and her hunter training
Naruto was given scrolls that include hirashin and rasengan and toad contract
Real story starts at titans curse
You decide if Bianca joins or not if she doesn't it's because of Naruto telling her his reaction to Mito joining
Feel free to make changes but the premise must stay the same and the pairing aswell
