I didn't have much luck at first, because I'd chosen a direction which didn't take me to any of their large territories. The most I was likely to find was a loner, or one venturing too far out.
After about an hour of searching, I sensed one. Like Quatre had claimed Zechs could sense them, I could as well—because, as much as I tried to deny it, they were my kind. I wondered how Zechs did it, but then realized it would be extremely hard for humans to tell them apart; of course they had to have some way of sniffing them out, or they wouldn't be able to hunt. It was probably some rare and highly prized skill that was genetic, but I didn't waste my thoughts thinking much about it.
The demon, unfortunately, was walking with a group of regular humans. I knew she had to know I was there, but they never worried about my presence unless I entered the central part of one of their territories.
It wasn't until I got close enough that I realized who was walking with her—Zechs, Wufei, and the woman Zechs had been talking to on the roof. I could see the faint lines which denoted a shoulder holster under Zechs' jacket, which most likely meant that they knew the girl was a demon and were stalking her in plain sight. I couldn't tell if Wufei had any weapons, but then again I didn't know if he preferred something other than a gun; and I wasn't sure whether the woman was armed or not.
Just then, I sensed another one of them. If Zechs noticed at all, he didn't give any outward sign of it, and I made the decision to assume he hadn't noticed. For the time being, I decided to ignore the other demon and follow the one in the group, to see how they handled it.
After a moment, it occurred to me that if Quatre had said Zechs' ability to sense them sometimes failed, it was possible they didn't realize the girl was a demon. Perhaps they had found her walking along after dark, while they were out hunting, and had offered to walk her home. In that case, they might be caught off-guard. To me, the presence of a second demon keeping out of sight signaled that they were planning an ambush. Demons were perceptive—I, of all people, knew that fact especially well—and it was entirely possible that the two demons knew the three were hunting them, and had turned their roles around: becoming the pursuers instead of the pursued.
I changed my decision, and decided to take out the second demon; it might provoke the girl into attacking, and then they could take care of her. It would be a wonderful way to prove to them that I wasn't a demon (never mind that I actually was), and that I was on their side.
The demon was up on the rooftops, following them; I would have to find a way up, or try to lure it down. I didn't want to risk changing and have Wufei and Zechs—and the woman I didn't know—finding out the truth about me.
I turned into an alley—I had been following them at a safe distance after watching them pass by from the mouth of a different alleyway—and found a fire escape that I was able to climb up. I gained the roof of the building after a minute's time, hoping that I hadn't made enough noise to alert anybody to my presence—especially the three, because I couldn't really help the fact that the demons could sense where I was. I had a vaguely funny thought: what if Zechs could still sense me? If I was lucky, perhaps he would mistake me for the second demon—who had just paused upon sensing that I was now on the roof, and was turning around. I drew my sword, and waited for him to come to me.
They were always ready for a fight; he lunged for me, and I darted out of the way. He had the advantage, because of his wings, and could move faster in the air than I could on the ground. However, I had experience fighting such unbalanced battles, and he was confused because he knew that I was also a demon.
He didn't waste any breath asking me about it, and I didn't taunt him—it wasn't my style, I preferred the silent fights. It was easier when I didn't have anything to distract me from hearing his wings, especially when he was behind me or overhead. He dropped to the roof, thinking that I would be easy or that it was all a misunderstanding, but it was his loss because I switched to the offence, slashing at him. He backed away and stumbled, not having the time to get airborne, and I took him down with a practiced thrust between his ribs.
Just so the girl got the message, and so the three of them were alerted in case they hadn't known, I kicked the demon over the edge for good measure—he wasn't quite dead, and a good four-story fall would finish off even the best of them. I watched him fall; and as he hit the ground all four of them turned to see what had caused the muffled thud of a body hitting hard concrete (the girl knew with certainty what had gone on, but still needed to see the outcome). She looked up and saw me; Wufei looked up also, but I don't think he recognized me from such a distance. I nodded at them and disappeared from the edge just as the girl lashed out at Zechs, but I didn't need to stick around to see—I wanted to get down there and assist if needed. Either way, my hatred for the demons outweighed my dislike for Wufei and Zechs.
