"That is composed of three words, so I am not called 'Oh My Gods,'" he remarks drily.
Oh boy. You really did get every negative aspect of me, huh, Galaxian.
"The closer title would be 'In the name of *insert name of deity except Athena here*, dang you!'" he states.
Oh boy.

"That's just one word," he goes before he breaks into his little unnatural laugh. "Alright, you finally got it."

"No problem. I expected it," he replies breezily.

Maybe because it'd be awkward for him to continue being a "ghost," or maybe because the narrator knows full well that they will forget that they left him still invisible (hint: Definitely the second reason) and then forego whatever consistency is at this point, Galaxian does appear now. Though, he's still outside of her view at the moment, but she can see him if she turns now. By the way, he was only invisible for the handshake thing before. Before that, he was also fully visible, just...not. If that makes any sense.
He's not really different. Just his usual gradient of blue hair, soullessly black eyes, and...is that an outline of armor nearby him? Hmm.
"Fine," he answers to her question, which according to all the rules of reality and social interactions is most probably a lie. "You?"

"Good to hear."

"Not particularly," responds Galaxian without much thought. Perhaps he already thought of his "cool" standards beforehand? Who knows.

"Do they have piranhas?" he asks in the most unconcerned tone ever.

"A pity," states Galaxian. The narrator thinks he just likes fish with teeth at this point.

"No negative opinion on it thus far."

"Figure it out?" he repeats, as a question. It seems he doesn't really know what there is to be figured out about it, so enlighten him, please.

"If you're interested, I probably have books back at my base," he goes, adding the "probably" because if he doesn't, then one of the bookworms in his gang hello Hitan and Firas...(: definitely will.

He remains undaunted. "Well, feel free to stop by at any point in time to get it, preferably during the daytime, however," he says as he just starts...walking off. Apparently he thinks business is finished or that that's a good place to end it, or whatever. Though, he does add, "Hopefully the one who bares the entrance is someone who would know where the books are, but if not, don't be scared of the ones who open the door while holding laser guns. They're harmless, mostly."
'Bares the entrance,' huh.
