We were making jokes about Attack Titan characters one day and came up with the name Han-G, imagining her [{Amber] in gangsta gear and gold chains. Amber decided she wanted to do it for real and I came up with Mike Check to match it. Then we were up late one night trying to think of more stuff to add and came up with the boom boxes. We just keep adding more and more stuff over time. 

I remember a pro level Satsuki (Kill la Kill) cosplayer who saw us at another con and that we were her favorite. Here we are with our inflatable boomboxes and dollar store shades and this legit cosplayer is complimenting us. I guess cosplaying really is all about having fun and making a good impression.
