Pokémon: the Strongest Winner in Life

Traveling to the world of Pokémon, I have an older sister, Sirona, who is controlled by a younger brother. I originally wanted to rely on my own ability to become the strongest trainer, but the system appeared... "Congratulations to the master for opening the newbie gift package and winning a divine beast lottery!" "Congratulations to the master for drawing the shining beast Lukia!" Maybe I was speechless looking at Lugia's Poké Ball in my hand. Obviously my dream is to become the most powerful trainer by my own ability. What does the system mean? "Why has my dream been realized before it even started?" Wuyou's face was troubled, but his heart was filled with joy. This novel and its characters are purely fictitious.
