Aqua of the Back... first he beats the crap out of Touma and now he even seduces a princess/queen of England?! That guy is badass beyond belief!
EDIT: Ah yes, and how could I have forgotten about the fact that they needed an army of Amakusa Catholics to beat him? Seriously, can't wait to see him in anime... which will probably be in 3rd season which is far, far away
