Meh. Shush, I was tired. I'm not saying the sword is in and of itself 'holy'; more along the lines of a very famous relic of sorts with special properties like the holy swords are to us. The in-universe explanation would be that it's connected to his aura somehow, and thus can become stronger with his large aura reserves.

There also seems to be some sort of connection between his aura and his sense of justice/honor/confidence. When he gets knocked around or is unconfident fighting Cardin, his meter drops dramatically, yet with the Pyrrah scene and when he lets Cardin punch him thinking it's the 'right' thing to do, it seems to glow and get stronger. Thus as long as he's confident and pure in spirit, he becomes much stronger and in turn can bolster his weapon as well. That would be a classic setup for a typical knight in shining armor.

"But his aura drops because he get's knocked around" True, but it doesn't seem to take much, especially if he's considered to have 'a LOT of it'. I think there's more at play here, especially seeing how much abuse some of the others can take and keep on fighting.

I guess forget the rest, it's just references and tie-ins to justify the theory, though I doubt they'd get THAT deep into it.
