I'm starting to wonder if Tatsuya and Miyuki might not be a form of white mutiny by their mother and aunt against both those that want to make mages into weapons and the family that is tasked to do so.

Yuutousei seems to hint that their aunt may care about both of them.

Elder Kudou's, who was the sisters teacher, statement that " They originally existed to develop new weapons, but they are no longer like that. Something that only exists as a weapon will someday be excluded from the world of men." as well as Tatsuya's comment about genorators being the end product of mages as weapons. It's not that uncommon that students share the same views as their teachers.

Tatsuya is pretty much the enbodyment of what the exact goal of the Yotsuba. And even when he is limited and hideing most of what he can do he scares the hell out of people.

Then there is Miyuki who is extremly powerful in her own right and also has a will of iron. There is no way she would be a puppet as the head of the Yotsuba. And her veiws on what was done to her brother pretty much garentee that there will be a house cleaning and change of focus if she takes over.

basicly in short they have made the kids loyal to each other first and formost and made sure that they don't agree with any of the more shady stuff the house is doing as well as makeing sure it would take an act of war to stop them.
