One plot idea could be the OC's struggle to live up to his father Hephaestus' reputation. He might face challenges in creating unique and powerful artifacts, while also dealing with the expectations of the other gods.

Naruto is the central character for sure. In addition to him, there could be characters from Greek mythology who cross over into the Naruto universe.
