"Lots of practice, no doubt." It's not that he can't imagine himself ever using something like this, but it's so far from his usual style that Inigo knows he'd really have to dedicate himself to practicing it for a long time to even be able to get used to this weight in his hands. Just holding it up like he does now is already much more of a struggle than he's used to with swords.

Although it makes sense, considering what Gladio looks like. That guy is so ripped! No wonder he'd be able to handle a sword like this.

"Don't get me wrong, I mean this in a positive way, but.. it really seems like a "you" kind of sword. It's exactly the kind of thing I'd imagine a guy like you would wield."
