This takes place in the Mesmerizer MV!

You and Miku were in a sunny field, just having fun. Until a little rainbow coin flung out of the air. It swung left and right, in a hypnotising manner. You reistsed, but Miku didn't. Her eyes darted back and forth, locating the little rainbow coin, her pupils getting darker in the process.

You tap her shoulder to get her to snap out of it..

"Oh.."

She mumbles, still following the coin..
