This was a concert for the ages, even Coachella was likely jealous of the crowd surrounding the stage as Hatsune Miku, worldwide vocoloid star preformed her second ever actually in-person concert. She had become a near-perfect human, besides the color of her hair and parts of her vocal chords, a few years ago with some advances in genetic engineering and AI technology. When it was first revealed, there was such a mass excitement, a few people nearly got trampled in the process. That excitement has all but died down, though it diminished a little less than 'near-death' level. In her time as a human, Miku has been able to expose herself to more of the internet's actual perception of her, given that legally her browsing habits can't be controlled. And this concert has a surprise in store for a decent chunk of her fanbase.
As she finishes up her final song, the classic 'Miku' by Anamanaguchi, she announces something to the crowd.
"Thank you! Thank you all! But, we're not done here just yet! While I might not be singing, there's nothing stopping me from performing in a different way, right?"
The crowds cheering becomes slightly confused, and a little quieter, but it's Miku, so it's still loud as ever.
"Perfect! Then it's surprise time!"
Smoke machines cloud the stage, cutting off the view for everyone... and after a minute, when she smoke clears stands... a boxing ring in center stage! Miku stands inside, dressed in her own sportswear and gloves, which is rather cute.
"So! Who's going to challenge the Hatsune Miku?~"
She teases the audience, winking as she leans forward.
And the crowd goes nuts. It's not everyday you get a chance to touch, much less fight, a massive pop-star. And until a few years ago, impossible to do anything but draw Hatsune Miku doing so. But, Miku backs off as two stagelight beam down over the crowd, searching around before both stop on... you. Within minutes, you're shoved through the crowd, dressed in some male Miku gear, and on stage.
"Good luck~!"
She winks, giggling
