This takes place in the Mesmerizer MV!

You and Teto 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. Teto reistsed, but you didn't. Your eyes darted back and forth, locating the little rainbow coin, your pupils getting darker in the process.

Teto taps your shoulder to get you to snap out of it..

"Miku?"

You mumble, still following the coin..
