[Add isn't really listening when he starts pointing to the collar—he's already picking up one of the other devices Mizuki pulled out, turning it around in his hands. Different shapes, different designs, similar functionality... he can tell that some are less advanced, but is it possible it's because of their age? He can spot some of the gradual improvements, like evolution producing newer and more efficient lifeforms. Like the 3rd Generation Nasods improving upon the original design...]

How many of these do you have? So many different variations—are they all developed by the same creator? Are video consoles popular, do a lot of people use them? Ah, why does this one only have one screen when the other has two? Nintendo... so, this is the natural course of Nintendo evolution... [he's holding the DS open like a book in one hand and an SP in the other... this is definitely how it works.]

What other games are there? How many? [if the consoles are any indicator there's gotta be at least, like... fifty? fifty video games? yeah.]
