Pokémon Was Born Noble and I Still Have a System

Born in a large hidden family, as the only son of the patriarch, the existence of the golden key actually has a system. This allows others to do whatever they want, so they have to let go of themselves. It's funny. Relying on my knowledge from my previous life, my superb training skills, and a little help from my family and system, I want to become the strongest champion in this league.
