what is Ruby's real family (au crossover)

who is Ruby's real family? that was the question that everyone asked since rubeckia was the adopted daughter of the father (in this au of course) everyone asked that question but her simple answer was that her family is common people who could not raise a baby because of their low resources which led them to abandon her well that was what they believed but no one expected the truth except rubeckia she already knew since she was reincarnated or actually revived in one of her many lives but that is for the story.
(in this au for as it says it is an au then it has very different things to the original then that's why Ruby's family will be a crossover au so sorry if you get confused but take it as a new story and not in if the original, this au the found in some tiktoks and videos but not found stories in any case I prefer not to regret then credits to its original author or whatever but the story if mine well enjoy this story that will have several sagas this is the 1 and the other sagas are about Ruby's family.
