The Game Villain Was Raised to Death by Me

Top Race, Clearly Differentiated Race Levels!! Nurture System~

I want to read a book like "After becoming a vampire cub, she was forced to carry a knife and go into battle". There can be a male protagonist, but I prefer the female protagonist to be uniquely beautiful. Nurture system! Nurture system! Nurture system! There must be a clear racial hierarchy! The male and female protagonists are both rare pure bloods of the top races!
