[@LetMeDoStuff]The mask is something personal to Ryuu. He'd kill somebody before giving it up. 


Not to mention Mikasa kept her scarf the whole time. 


But back to the mask, it was something his Sister made for him (Mind you without the Titan mouth, he added that one himself). Its actually important to the character. But its not gonna be an issue, its just a mask and I figured it would be fun to make the captain say something about it. 

Also, I'll have Ryuu part two up later. I was a little confused by your post, LetMeDoStuff. It made it seem like the parade formation is over and the trainees gotta meet each other. (With your character yelling something about hating talking to people or something like that), would that be correct or am I wrong in this assumption?
