As wordlessly as ever, Katsuro moved along with the rest of the students to the changing rooms. He hadn't paid much mind to the people that had arrived after him, simply focusing on his own well-being, but the attitude of one of the female students suggested that many students were at fault here. Yes, perhaps it isn't something that can just be excused, but Katsuro for one wasn't pointing fingers and slapping wrists, either. It was of his understanding that discipline was an art better left for the superiors rather than the students; Katsuro saw an impression that Sumiko had somewhat of the same idea, given the reaction to the girl's comment.

Now that it was time to suit up proper, the young man joined the rest of the students to the changing rooms, keeping somewhat near the head of the pack. Ducking into the male rooms, Katsuro took a few moments to recall the number and location of his locker, and several more moments to actually find it. From there, it was a matter of stripping down to his essentials, so to speak, and quickly slipping on the pilot suit. He took care to deliberately put on a suit in a vaguely smooth manner; one of the tips Katsuro got from his father was to make sure to put on the suit in a slow, fluid motion, so that later on he could don the suit in a single, quicker motion. Of course, like anything, it took practice to get to that level.

Katsuro gave himself a bit of time afterwards to adjust to the form-fitting nature of the suit. Hopefully working it into something more comfortable didn't take too long... but along as it didn't really impede him at all, it wasn't a big deal.
