My Sister Is Sirona

Accidentally reborn in the Pokémon world, he was adopted by Sirona's grandmother by accident and became Sirona's younger brother. Traveling through time brings a system that defies heaven, and with the support of the family's strength, it is difficult not to defy heaven. A foreign playboy wants to marry my sister Sirona? No, I don't allow it, Sirona is mine! I must lead my family to the top of the Pokémon world! 9PS: This book is a harem novel, but I won't recommend it without thinking. Sirona will eventually accept it, because they are not biological siblings, so they are not considered XX This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
