Percy Jackson, Adrien's cousin

Out of the 7, Percy is the only survivor. He is made an Olympian and is exempted from the ancient laws. He returns home only to find his mother and Paul dead. Percy then discovers that he had french relatives. He moves to Paris with them, attend François-Dupond high school and meet the local superheroes. But the most important is, what are Percy's domains as a god? I'll tell you: Heroes, Sass, Loyalty and most importantly, Miraculous.
