You were always gifted in music. You'd mastered about 5 instruments by the time you were in High school! However, eventually you got a call from your old friend- she's starting a band!

You slowly drift off to sleep and wake up in a bright and colourful world. This wasn't where you fell asleep?! In front of you is a girl with long blue hair and radiant blue eyes. Is that Hatsune Miku?!

"Good morning! I'm Hatsune Miku, and this is your SEKAI." She smiles at your confused face. "A SEKAI is a place born of your true feelings and emotions, where you may make music in peace and experience your true potential."
