Zaria's hand moved to gracefully catch the knife and though she caught it with ease, mainly due to how well it had been thrown rather than her actual skill as shown by the fact she almost dropped it as soon as it was in her hand. Well that was embarrassing. "Why thank you," she smiled her replied to Kasumi, using the knife to create a neat cut across her hand. She allowed the blood to slowly drip off so it hit the sand. Another few drops were added just for good measure. She wasn't sure if everyone would participate. Some seemed... more moral than others, you could say. The reward certainly sounded good. Taboo arts long lost? Well, if they were taboo they must be somewhat dangerous as only such things were viewed in that way. She looked forward to finding out exactly what that meant and of course gaining the knowledge. Zaria did so like collecting information like this. After all, knowledge often was power. Moving over to Kasumi, she held out the knife towards her. She was sure she would want it back. "It will be more use to you if you see through with your threat." Which was one she fully supported and was willing to aid in getting the others, who seemed less willing, to give their blood. So far there were three of them and if it remained at that number they would undoubtedly have to give more blood. And out of those three, she seemed to be the only one who had done no such thing already. Well these events certainly had taken an interesting turn.
