And the question that stays on the air is, why? It doesn't make any sense All for One the biggest villain holds the most powerful peculiarity of MHA being afraid of a wealthy family. And it makes even less sense to MC's sister. Remember that the strongest figures in this world are around All might and All for One, it is absurd that she, being someone born normally in this world, being as powerful as the MC (which according to what was said to have, is already stronger than the previous two).
Honestly, giving him a super op sister that is just as strong as him makes his reincarnation worthless. What is the point of him being reborn in Mha with Gil's abilities if he has a sister who has another version and even call it Queens rule? I feel like it's a poor way to add anime comedy in the form of a bro-con while making her powerful enough to make any enemy that Gil makes become killed. You basically introduced someone stronger than All might into canon who is super young, because she existed before Gil was born. With this powerful family, I can't believe they wouldn'tve been able to make their business world wide even without golden rule.
