Aleister is an idiot. He should just personally kill Hamazura if he really wants to get rid of him. There's noway anyone in the world will survive once Aleister gets serious. WHF is with that omni-present!?
ANd seriously, Touma is the only protagonist who never kills his opponent, but even saves them. Accelerator, Hamazura and Aqua all kill their opponents. He's actually the most awesome (or idiotic) character in the whole series that no one could match. :P
