Requiem paused from greeting his crew, and finding out about their happenings, upon interruption from a girl who apparently had declared herself to be joining his crew.
All things considered, he was short handed. However, on the other side of things, she was a wildcard. An unknown in any game increased the risk, but quite often increased the game's interest as well. In this case, his biggest concern was simply that only a handful of people would ever volunteer as she did, and he expected that more than half of those worked for rival warlords. He had made more than a couple of enemies within the Warlord ranks, and she wouldn't be the first to have been spying for one of the others, assuming that she was in fact, a spy.
He listened quietly as the girl explained herself, and her intentions, and then he listened in amusement as his crew argued back. Eventually, it came down to his vote. "Well... You seem earnest enough about joining, but I don't actually know you. I don't know what you're like, or what your goals are. So, here's the deal. We're all going on something of a treasure hunt. Our target is somewhat popular as of late. The murderer of the island. There's also a side prize buried deeper in the caves that we're hunting in. The caves are remarked to be boobytrapped, but the prize is quite valuable. Depending on how you do in assisting us towards our goals will decide on whether or not I accept you as part of the crew" He informed her, ignoring her devil fruit powers entirely. He'd seen a lot of things in his travels, and quite frankly, while what she had most certainly qualified as unique and potentially useful, if she couldn't work together with his family, then she wasn't cut out for his crew.
He looked her over again before nodding to himself. "So, do we have a deal?"
