Just an AU where Kuroko and Akashi are childhood friends who only ever separated during high school.
"I thought we're supposed to play basketball!" The Miragen drags Kagami on their shenanigans to get on to some stage, dancing and singing till their hearts and mics drop. All for vanilla shakes... and maybe some of those other stuff. It was all worth it at some point. Probably. It's what Kagami tells himself to literally keep him from killing these six idiots.
"...I'm dying"...Kuroko is slowly fading away and within that group of friends, Akashi's the only one who knows about it.
