"Can that thing work for long periods of time?" You ask. Man, to be invisible indefinetely. That certainly fires up your imagination engine. You could whisper creepy stuff in people's ears, pretend to be a poltergeist, or perhaps observe where you normally could not. You grin.
"Hmm, I'm not actually sure. I sometimes use it when I'm looking for stuff. And some pranks, too. You're gonna do pranks, aren't you?" Nitori asks.
"Pranks? No, not at all. I'm just going to lend a helping hand to science!" You make a fist with your Devil Bringer.
"So, how do I turn it on? I'm going to test this baby for a long time."
"Well, you put this on your wrist. Left wrist." Nitori helps you attach the watch-resembling device to your wrist. Okay, that's way too many spinning pieces. It looks like the camouflage device has so many rotating parts that it kind of resembles a solar system. Guess you can change the axes, for whatever reasons.
"Right. Let me adjust the field parameters." Huh? Nitori messes with the watch a bit, you don't really get it.
"Okay, just hit this button, and you're invisible!" Nitori points at the only button on the device and just grins.
"Be sure to do glorious pranks!"
"Yeah, sure." You say, and press the button surrounded by spinning stuff.
Your vision flickers, changes colors. A moment passes, and you can see again, only that everything has a greenish tint now. Hey, this is kind of awesome. You take a look at your own hands... What hands? Hah, this is brilliant. You're actually invisible, well, you can vaguely see your outlines. But if you're unmoving, you're certainly impossible to see.
"Oh, damn, this is cool." You shout.
"Hey, Nitori, what about things I touch? Will they turn invisible?" You ask.
"Umm, it's sort of a field, so, if you keep it close to yourself, it's in the field. But, if you hold something extended, or really long, it'll exit the field."
"Right. Keep things close. So, can anything damage it? Like, water, for example?" You keep questioning.
"I don't know, you're the tester."
"Oh, ofcourse. Right, I'm off then, maybe I can catch up with Hina." You give a little salute to Nitori, then realizing, she couldn't see that.
You step outside of Nitori's cave. You are actually not casting a shadow. The sunlight just, goes through you. Looks like it's noon, too. Right, off to follow Hina.
Where would Hina go in the first place? You don't really have a clue.
 That hill, over there. With the flowers. If she isn't there, you can get better view, instead.
