Ahahah.
Funny...
I like how they try to make the sister seem like a normal lovable human being.
Nope, still a bitch, I still want her to disappear.
Also, Al is treated strangely. I mean, he's (outwardly) young, so of course you would not let him do anything he wants, you would try to teach him well even if he doesn't want it...
BUT! They let him go to the village alone, they force him through gruelling training sessions, they steal his ideas to make money but don't recognise him as a genius, they never seem even slightly concerned for his physical and mental well-being and they usually ignore his point of view completely, except, again, when they can make money off of it.
His family is actually shit. I think it would be better for him to be a noble orphan...
