For a second Kuronotsurugi's eyes flicked to look at Hikari, who had spoken to him, saying that the person at the door was Kakashi, but even with that being said he doesn't lower his hand, nor does he lower his guard, eyes completely focused on the front door once again. A mere moment later it opens, indeed revealing the man whom Hikari said it would be, and only then does Kuronotsurugi place the kunai back in it's holder, though he was still gazing steadily at Kakashi, not blinking or looking away. Kuro knew that this was the other male's place, and it usually would be the other on guard finding a stranger inside their home, but this was just how he was. His face had gone back to the usual blank, lips in a set line, eyes unemotional, he was once again a plaster mold, showing nothing. Exactly like he'd been before the mission with Hikari, and for some time even when they'd been on that said mission.<br/><br/>He was silent as Kakashi spoke up, apologizing for walking in on them, which he thought was pointless, as this WAS his house after all, so it made no sense for him to have to say sorry for coming home. He had heard that Kakashi was a strange one, but all things said aside... Hikari confronts Kakashi, asking, or rather stating, that she thought Kakashi was on a mission, in which the latter replied to saying that it was a short one, before looking to him and saying hello. A shallow, almost unseen nod was given from Kuro as a greeting, saying nothing still. It was almost as if someone had stolen the voice right out from within him, leaving nothing but a soundless shell behind. Even when Kakashi goes on to talk more, saying that they haven't met officially, and introducing himself with his full name, Kuro says nothing, well, almost nothing. A near inaudible introduction of himself could almost be heard, but after that he is quiet once more.<br/><br/>He was relieved when the older male Shinobi turned his attention once more to Hikari, though his own eyes were fixated on Kakashi. There was something about him, that made Kuro wonder. He knew for sure that he'd been being followed, for quite some time now, actually, if he thought hard about it, it had been for years that he'd been tailed, maybe about two or so. The conversation between the two was almost muted to Kuro, his thoughts elsewhere, thoughts whirling in his mind, as he tried to figure out something to the sensation he was getting from this guy. Maybe...maybe this was the one. He'd have to check to be sure, but how was he to do that? And how would he do it without; one: being caught, and two: without seeming suspicious? Keeping one eye on Kakashi, he turns slightly, tilting his head just slightly, the gears turning within his mind, his eyes having a dim and faraway look, shaded almost.<br/><br/>He didn't turn his head when Kakashi moved to cross the room, standing against the door frame, feeling Kakashi's eyes on him now, almost as if observing him...yes, Kuro had to find out. For a split second he flicks his eyes towards Kakashi, looking straight back at him, a flash of red lighting up his vision, and it was rather eerie, since his pupils became slit like, but it was gone in a mere moment, almost as if it had been a trick of the light, or an illusion of the mind. It had not been though. It was something that Kuro had come up with quite a while ago, and he was pretty sure that no one knew he'd created this particular little 'trick'. It was a way of quickly assessing another's chakra using his Sharingan, in a split second, to read the flow and pattern, determining whom it belonged to, etc, and it took just a few moments, a few blinks of the eye. However, it wasn't a solid jutsu, and there were still flaws, so he'd need back up data somehow. But even from that, he could see that the chakra from Kakashi was VERY similar to the chakra of his supposed observer. He had no doubt in his mind that he was being followed, it would be just stupid to NOT have him followed, considering who and what he was.<br/><br/>Picking up the soft sigh of Hikari, he looks to her. All this took a few seconds, from looking to Kakashi, and then to Hikari. Hearing her mumbled apology, he simple shrugs it off, cold and frozen in personality once more. He was half tempted to leave, but the other half of him wanted to stay with Hikari. It was an internal struggle, and slowly the side that wanted to leave was starting to gain ground, especially now that Kakashi was here, and there was no sign of him moving from his spot in the doorway any time soon. He looked back at her as she gazed at him, his features as blank as an unpainted canvas, seeing the worry and slight flicker of fear on her own face. Lowering his head, he then closes his eyes, and takes a deep breath, slowly exhaling the air he'd taken in to his lungs. This was just getting really tense...What to do?<br/><br/>Slowly, he stands up, still quiet as the night in winter, no noise coming from even his movements. It was almost as if he didn't even exist physically, and all he was happened to be a false image. Opening his eyes now, he looks over to Hikari, not quite sure what he truly wanted to do. He wanted to stay, yes, as he was having quite an amazing time, something he'd not experience in quite a while, but he felt...trapped. Would she want to see him again if he left? Or would she be angry, and end up not wanting to talk to him? What was the answer? Not only that, he wanted to get a deeper look at Kakashi's chakra...<br/><br/>Finally he speaks up, his voice unfeeling and dull. "It's getting a bit late, so I probably shouldn't stay too long. I'll finish dinner, but first may I use the restroom?" He glances once more at Kakashi, before focusing his attention on Hikari, watching her face for her reaction to his words. He wanted to apologize, he was more of a coward than he wanted to admit.
