"Wha—" Moby mumbled under his breath.
Artorias's duel request seemingly came out of nowhere. He had just saved him from those two and now here he was challenging him to a fight.
Part of him thought that this was a perfect opportunity to see where he would stack up. There was no one watching them so he might be able to use more techniques and he would not have much of a loss in reputation when he loses.
But, at the same time, what was the point in all of that? If he fought him now, he might not have the chance to find time to contact his friends back on earth. He was more than certain that with his current power, even if he used his spirit mode, he would not even be able to bait out his ability. He would need to use sin mode to force it out of him, and for a simple spar, would it even be worth it to expose such a thing? It might cause some problems.
