He... what? Was that a joke? Explaining the things here was one thing, but he hadn't expected to clarify something so... ordinary. Wouldn't someone that age have heard announcements through an intercom every day in school? Or maybe he was from some rural area without much technology. They were few and far between, but places like that still existed in Japan as far as he was aware, and he could only imagine the same was true in other parts of the world. But still, one would think he'd at least still know the word. On the subject or unfamiliar words, Kyousuke couldn't say he'd heard of "magitechnology" before, but made no comment on it; he half wondered if the other boy was simply making things up to sound more intelligent, and if that was true, he had no intention of taking the bait.

"It's... a system of speakers and mics you can use to communicate between places," he explained with a frown. His tone was uncertain, but less because he didn't know what he was talking about, but more because it was such basic knowledge he wasn't even sure he could describe it properly. That, and he still wasn't sure if this was some prank he was misreading.

Being told he sounded knowledgeable about the place came as surprise too, since as far as he was concerned, it couldn't be farther from the truth. "... Not really. Only what I've seen and heard so far. All the important pieces are missing." That... wasn't pleasant to admit, but it was true, and it was better not to give the wrong impression. Knowing the basics of what was going on didn't amount to much without any hint of the aspects behind them or how to maneuver against them, after all. But it was still reassuring to hear, and could make him feel a little less like he was dragging his feet or wasting his time. ... He wasn't about to admit that out loud, though.
