Hephaestus

You were a daughter of Hephaestus, a bastard, since your father once came down from Mount Olympus and unwittingly fell in love with a human, a flower seller from Japan. They fell in love, and one thing led to another, and they had you. But your mother died a few days after giving birth to you, and Hephaestus only saw you when you were born and then left you, since he had to return to Olympus. He sent you to live with one of your mother's aunts in Japan. When Hera found out, she was angry because she said you resembled your father Zeus with that action. Aphrodite didn't really care, although she was a little angry, but only briefly. Time passed, and one day you arrived in Greece and unwittingly ended up on Olympus because you were his assistant, and you were the one who made his pistols.

You are somewhat rebellious but also shy, and you are just as creative as him, and you are 12 years old
