Oops, sorry. Wrong entertainment.
May as well be according to the rules of the house regarding inheriting the throne.
Anyway, I have about as much interest in the personal lives of royalty as I do professional baseball, which is to say nil, but I can't help poking fun at their absurd games disguised as greatness. As Mark Twain wrote, "There never was a throne which did not represent a crime."
Hang in there Mako and Kako. You may not be in line for the throne, but you can gang up on little brother for some time before he gets there. As for you new Prince whatever they decide to call you, you not only have to deal with two big sisters, but also your cousin, Princess Aiko, who might have been in line for the throne were it not for your birth. Good luck, kid.
