I would be a guardian because I'm always looking after people and giving them advice and guiding them, it's just the type of person I am. Also, I'm one of those people that if I get close to someone, then I'd do whatever it takes to give them what they want. So, I'd be prepared to die for the one I love if I really, really had to, if there was no other way.

I never actually considered why you can't summon the same Aeon in a fight with another summoner, your point is valid, if not definite. But still, my idea of a combined attack with the summoners is good, no? Anima, The Magus Sisters, Yojimbo all being summoned at the same time? Still, an awfully good fight, yah?
