"Ah, jeez," Ijemaru muttered when he saw Heather take out a pack of cigarettes. He stood up, "I'll be in my room. Don't need to be destroying my body in more ways than I already am." He left the hunter's room and retreated to his own, finishing his steak before pulling out the boxy little contraption he'd been working on earlier. He then fished around in his pack until he found a secure little case. Inside were two vials of blood: one a deep red, the other black. He put a small sample of each into the device via a small retractable needle. First he sampled the red human blood. There was a quiet mechanical sound inside the box and a number appeared on the screen: 0%. He tested the demon blood next: 100%. So far so good, but he needed to make sure it worked with mixed samples. Cleaning the needle with some antiseptic, he stuck it into his own arm. 18%, so he was still much more than half-human. At least, that would be the case if his program was working as it was supposed to.<br/><br/>In design, the contraption was painfully primitive. Basically, it was a small metal rectangle with a little screen on the front. If you pushed two buttons on the side a little needle would stick out. When you released the buttons, the needle sucked in a small blood sample and retracted. From there, the blood went to a small compartment in the middle where an equal volume of holy water was exposed to it. Holy water destroyed demonic cells, so the percentage was based on the amount of blood left over, or how much holy water, if you wanted to think of it that way. When he was certain it worked properly he would see about making a version that wasn't quite so painful to look at. Well, despite it's unimpressive appearance, it was a revolutionary new technology.<br/><br/>He cleaned the needle again and a thought occurred to him. Battler and Ebisu would be at dinner a while longer, and he had a potential test subject two rooms away. Allowing himself to be hopeful, Ijemaru knocked on the door and let himself back into Heather's room after a short pause. "There<span style="font-style: italic">is</span>something I could use some help with," he said to her, holding up the ugly but ingenious little box. "I need a blood sample from a hunter who's, well, human."<br/><br/>((Human hunters range from 1%-6%, depending on the amount of toxins in their body))
